Getting 404 error only when using .NET framework

I'm trying to create a version in JIRA for a specific project.
I'm able to do the process via Postman by building my requests manually, but it fails with a 404 when creating the version record via .NET.
I'm assuming .NET adds pesky parameters to the request that Postman doesn't do.
The weird thing is that the authentication call works, but the the version creation fails.
Here's the helper I wrote:
public class JIRA
{
private string AuthToken { get; set; }
private const string c_JIRAUrl = "https://org.atlassian.net";
private const string c_LoginUrl = c_JIRAUrl + "/rest/auth/1/session";
private const string c_CreateVersionUrl = c_JIRAUrl + "/rest/api/2/version";
public JIRA()
{
//this works...
var authResponse = ExecuteRequest(c_LoginUrl, "POST", new
{
username = "login",
password = "password"
});
AuthToken = authResponse["session"]["value"].ToString();
}
public void CreateVersion(string name, string projectKey, ProjectEnvironment environment)
{
//lets hardcode the same data I use in Postman for testing purposes...
var createVersionResponse = ExecuteRequest(c_CreateVersionUrl, "POST", new
{
description = "An excellent version",
name = "1.1.2",
archived = false,
released = false,
project = "TEST"
});
}
private JObject ExecuteRequest(string url, string method, object data)
{
HttpWebResponse response;
var jsonDataString = JsonConvert.SerializeObject(data);
byte[] dataBytes = Encoding.Default.GetBytes(jsonDataString);
var responseText = string.Empty;
var wr = (HttpWebRequest)WebRequest.Create(url);
wr.ContentType = "application/json";
if (!string.IsNullOrEmpty(AuthToken))
wr.Headers.Add(HttpRequestHeader.Authorization, $"Bearer {AuthToken}");
wr.Method = method;
wr.ContentLength = dataBytes.Length;
wr.Accept = "application/json";
using (var webStream = wr.GetRequestStream())
{
webStream.Write(dataBytes, 0, dataBytes.Length);
response = (HttpWebResponse)wr.GetResponse();
}
using (var sr = new StreamReader(response.GetResponseStream()))
{
responseText = sr.ReadToEnd();
}
return JObject.Parse(responseText);
}
}
The CreateVersion method always fails with a 404.
As I've said, doing the same (retrieving the token, creating the version) all works in Postman.
Any ideas what's going on ?
Thanks.

Apparently, when retrieving the token (/rest/auth/1/session) the response contains cookies that POSTMAN was sending back in the 2nd request (creating the version). I had to fire up Fiddler to find out it was doing so because its UI was not saying so.
My .NET client was not doing so. When making it do so, it works.
I'm a little miffed that a REST service expects cookies...

POST or Get Request with Json response in C# windows Form App

I made an API in server side with PHP + Laravel framework which accept both GET & Post requests with some special parameters.
It's address is : http://beresun.ir/API/Orders/0
and it gets these parameters :
token > string ,
restaurant_id > integer ,
admin_id > integer ,
token_id > integer .
if we send a request with GET method with these parameters, for example it will be :
http://beresun.ir/API/Orders/0?token=2JEuksuv86DcFmLrQa7nna4QDeowuGTqpyUK0pf9wSlbe6D5hLtEVxvzMT5gAZG0xBKy00HxS3J79mcr8F54dBD0uIg5HX5fzPOAP&restaurant_id=1&admin_id=2&token_id=40 which returns a json data , you can click on the link to see the results .
the response json data includes some information about customers and it's products.
now I want to make a windows application for this service with C# and request data from this API with POST or GET methods :
I want to use this API to get Json data from Web server and save them in my Windows application , So I created two functions in one of my Form Classes :
using Newtonsoft.Json;
using System;
using System.IO;
using System.Net;
using System.Text;
using System.Windows.Forms;
public partial class MainActivity : Form
{
string token = "2JEuksuv86DcFmLrQa7nna4QDeowuGTqpyUK0pf9wSlbe6D5hLtEVxvzMT5gAZG0xBKy00HxS3J79mcr8F54dBD0uIg5HX5fzPOAP";
int restaurant_id = 1;
int admin_id = 2;
int token_id = 40;
private void SendWebrequest_Get_Method()
{
try
{
String postData = "token=" + token +
"&restaurant_id=" + restaurant_id +
"&admin_id=" + admin_id +
"&token_id=" + token_id;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://beresun.ir/API/Orders/0?" + postData);
request.ContentType = "application/json; charset=utf-8";
request.Accept = "application/json";
request.Method = WebRequestMethods.Http.Get;
WebResponse response = request.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream());
String json_text = sr.ReadToEnd();
dynamic stuff = JsonConvert.DeserializeObject(json_text);
if (stuff.error != null)
{
MessageBox.Show("problem with getting data", "Error");
}
else
{
MessageBox.Show(json_text, "success");
}
sr.Close();
}
catch (Exception ex)
{
MessageBox.Show("Wrong request ! " + ex.Message, "Error");
}
}
private void SendWebrequest_POST_Method()
{
try
{
// Create a request using a URL that can receive a post.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://beresun.ir/API/Orders/5");
// Set the Method property of the request to POST.
request.Method = "POST";
request.Credentials = CredentialCache.DefaultCredentials;
((HttpWebRequest)request).UserAgent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";
// Create POST data and convert it to a byte array.
string postData = "token=" + token +
"&restaurant_id=" + restaurant_id +
"&admin_id=" + admin_id +
"&token_id=" + token_id;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/json; charset=utf-8";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
MessageBox.Show(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
MessageBox.Show(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
}
catch (Exception ex)
{
MessageBox.Show("Wrong request ! " + ex.Message, "Error");
}
}
}
Now Here is the problem , when I test the API it works fine , but when I request data from my application , it returns error and not working .
Can anyone explain me how I should request data from this API , to get data , I searched a lot , and I used many different methods , but none of them worked for me . maybe because this API returns very much Json data or maybe request timeout happen. I don't know , I couldn't find the problem . So I asked it Here.
I don't know what I should do .
Thanks

Oki so i run your code :
private string TestURL = "http://beresun.ir/API/";
string token = "2JEuksuv86DcFmLrQa7nna4QDeowuGTqpyUK0pf9wSlbe6D5hLtEVxvzMT5gAZG0xBKy00HxS3J79mcr8F54dBD0uIg5HX5fzPOAP";
int restaurant_id = 1;
int admin_id = 2;
int token_id = 40;
public async Task<string> test()
{
try
{
using (var Client = new HttpClient())
{
Client.BaseAddress = new Uri(TestURL);
Client.DefaultRequestHeaders.Accept.Clear();
Client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
string postData = "token=" + token +
"&restaurant_id=" + restaurant_id +
"&admin_id=" + admin_id +
"&token_id=" + token_id;
HttpResponseMessage responce = await Client.GetAsync("Orders/0?" + postData);
if (responce.IsSuccessStatusCode)
{
var Json = await responce.Content.ReadAsStringAsync();
// !
return Json;
}
else
{
// deal with error or here ...
return null;
}
}
}
catch (Exception e)
{
return null;
}
}
and its working am getting the json file ,, i think your mistake is in postData is string Not String ! a simple type can amazing harm !

try this:
private string URL = "Your Base domain URL";
public async Task<YourModel> getRequest()
{
using (var Client = new HttpClient())
{
Client.BaseAddress = new Uri(URL);
Client.DefaultRequestHeaders.Accept.Clear();
Client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage responce = await Client.GetAsync("Your Method or the API you callig");
if (responce.IsSuccessStatusCode)
{
var Json = await responce.Content.ReadAsStringAsync();
var Items= JsonConvert.DeserializeObject<YourModel>(Json);
// now use you have the date on Items !
return Items;
}
else
{
// deal with error or here ...
return null;
}
}
}

Unable to Post on Pinterest using their API

I'm receiving a 400 Bad Request error message when posting a pin on Pinterest. It works using Postman, but doesn't work programmatically. Using C#, has anyone been able to successfully post a pin on Pinterest without using the pinsharp wrapper?
private void postPinterest(string messages, string id, string usertoken, string image, string boardname, string username)
{
string link = null;
boardname = boardname.Replace(" ", "-");
string board = username + "/" + boardname;
string url = "https://api.pinterest.com/v1/pins?access_token=" + usertoken;
StringBuilder sb = new StringBuilder();
if (!string.IsNullOrEmpty(board))
sb.Append("&board=" + HttpUtility.UrlEncode(board));
if (!string.IsNullOrEmpty(messages))
sb.Append("&note=" + HttpUtility.UrlEncode(messages));
if (!string.IsNullOrEmpty(link))
sb.Append("&image_url=" + HttpUtility.UrlEncode(link));
string postdata = sb.ToString().Substring(1);
PostData(url, postdata);
}
private object PostData(string url, string postdata)
{
object json=null;
try
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
// req.Accept = "application/json";
using (var stream = req.GetRequestStream())
{
byte[] bindata = Encoding.ASCII.GetBytes(postdata);
stream.Write(bindata, 0, bindata.Length);
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
string response = new StreamReader(resp.GetResponseStream()).ReadToEnd();
json = JsonConvert.DeserializeObject<dynamic>(response);
return json;
}
catch (WebException wex)
{
if (wex.Response != null)
{
using (var errorResponse = (HttpWebResponse)wex.Response)
{
using (var reader = new StreamReader(errorResponse.GetResponseStream()))
{
string error = reader.ReadToEnd();
return json;
}
}
}
}
return json;
}
EDIT:
It doesn't work using the JSON format or x-www-form-urlencoded format.
I changed the content type to application/x-www-form-urlencoded and now I'm receiving the error message below. I receive 400 Bad Request error using JSON format:
"{\n \"message\": \"405: Method Not Allowed\",\n \"type\": \"http\"\n}"

The problem is the the parameter that you are posting.
In the Api i could find board as a parameter but both note and image comes under field parameter which specifies the return type JSON.
As per documentation on this page you can post in this format
https://api.pinterest.com/v1/boards/anapinskywalker/wanderlust/pins/?
access_token=abcde&
limit=2&
fields=id,link,counts,note
So I tried the following and its getting response
https://api.pinterest.com/v1/boards/?access_token="YourTokenWithoutQuotes"&fields=id%2Ccreator
Would suggest you to first test the Api you are hitting putting a breakpoint inside the PostData function and check if the passed url is in the correct format and compare it with Pininterest API Explorer.
As you might have already received authorization code and access token so I am assuming your post function should be working fine.

public string postPinterest(string access_token,string boardname,string note,string image_url)
{
public string pinSharesEndPoint = "https://api.pinterest.com/v1/pins/?access_token={0}";
var requestUrl = String.Format(pinSharesEndPoint, accessToken);
var message = new
{
board = boardname,
note = note,
image_url = image_url
};
var requestJson = new JavaScriptSerializer().Serialize(message);
var client = new WebClient();
var requestHeaders = new NameValueCollection
{
{"Content-Type", "application/json" },
{"x-li-format", "json" }
};
client.Headers.Add(requestHeaders);
var responseJson = client.UploadString(requestUrl, "POST", requestJson);
var response = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(responseJson);
return response;
}

Signing into drupal website remotly using C#.net and json

I want to create a form in C#.net which can sign me in through a drupal website.
Service 3.x module is enabled and Rest server is running on my website correctly.
My only problem is how to serialize the username and password into json format?

Finally a solution :
I've got a windows form , contains a textbox , a masked-textbox and a button (called button3 below) ,
on button click event , the textbox and maskedtextbox contents will placed in the user object which is constructed using this class :
class User
{
public string username;
public string password;
public string name;
public string number;
public string address;
public string email;
public User(string user, string pass, string name = "", string number = "", string address = "", string email = "")
{
this.username = user;
this.password = pass;
this.name = name;
this.number = number;
this.address = address;
this.email = email;
}
}
then converted this object into json model using Json.net library
in the rest it makes a request the incoming cookie will store in cookieJar and for rest Requests you must copy this cookieContainer into your request cookieContainer and you will stay logged in.
this is the rest of Code :
private void button3_Click(object sender, EventArgs e)
{
CookieContainer cookieJar = new CookieContainer();
User user = new User(textBox1.Text,maskedTextBox1.Text);
string url = "http://"your-web-address"/"your-rest-service"/?q="your-resurce"/user/login.json";
try
{
var request = (HttpWebRequest)WebRequest.Create(url);
request.ContentType = "application/json";
request.Method = "POST";
request.CookieContainer = cookieJar;
using (var streamWriter = new StreamWriter(request.GetRequestStream()))
{
string query = JsonConvert.SerializeObject(user);
streamWriter.Write(query);
streamWriter.Flush();
streamWriter.Close();
}
var response = (HttpWebResponse)request.GetResponse();
using (var streamReader = new StreamReader(response.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
}
//Check to see if you're logged in
url = "http://web-address/rest-server/?q=resurce/system/connect.json";
var newRequest = (HttpWebRequest)WebRequest.Create(url);
newRequest.CookieContainer = cookieJar;
newRequest.ContentType = "application/json";
newRequest.Method = "POST";
var newResponse = (HttpWebResponse)newRequest.GetResponse();
using (var newStreamReader = new StreamReader(newResponse.GetResponseStream()))
{
var newResponseText = newStreamReader.ReadToEnd();
}
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString(), "Can't access server");
}
}
note: Second request is just to test if drupal knows me.

Your question is quite ambiguos, but i could show you the method to log in.
To Log in into Drupal Site using services you can enable the user resource and the actions Log in ( and Logout ).
Use the following to log in, ( make changes according to your set-up).
URL
- HOST: "http://www.yourserver.com"
- PATH: "/service-end-point/user/login"
METHOD
- POST CONTENT-TYPE: application/json
BODY
- RAW Input:
{ "username":"demo#gmail.com", "password":"demo" }

Sending data to php from windows phone

I need to send some data from windows phone 7 to php page through POST method, I have the following code at wp7 side
public void SendPost()
{
var url = "http://localhost/HelpFello/profile.php";
// Create the web request object
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
// Start the request
webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
MessageBox.Show("data sent");
}
void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
// End the stream request operation
Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
// Create the post data
// Demo POST data
string postData = "user_id=3&name=danish&email_id=mdsiddiquiufo&password=12345&phone_Number=0213&about_me=IRuel2&rating=5";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Add the post data to the web request
postStream.Write(byteArray, 0, byteArray.Length);
postStream.Close();
// Start the web request
webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
}
void GetResponseCallback(IAsyncResult asynchronousResult)
{
try
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response;
// End the get response operation
response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamReader = new StreamReader(streamResponse);
var Response = streamReader.ReadToEnd();
streamResponse.Close();
streamReader.Close();
response.Close();
}
catch (WebException e)
{
MessageBox.Show(e.ToString());
}
}
and following on my localhost, to send the data to database
<?php
require_once("constants.php");
$user_id = $_POST['user_id'];
$name = $_POST['name'];
$email_id = $_POST['email_id'];
$password = $_POST['password'];
$phone_number = $_POST['phone_number'];
$about_me = $_POST['about_me'];
$rating = $_POST['rating'];
$query="INSERT INTO profile(User_ID,Name,Email_ID,password,Phone_Number,About_Me,Rating) VALUES ({$user_id},'{$name}','{$email_id}','{$password}',{$phone_number}, '{$about_me}' , {$rating})";
mysql_query($query,$connection);
mysql_close($connection);
?>
When I run the code I have no errors it means code is working fine, but no data is inserted in the database.

I think there is a better way than HttpWebRequest. That is WebClient. You can change the method there and append data like you do in get string. key=value&key2=value then when you invoke that request and get the response try debugging and getting the output from VS or if that is difficult simply assign he string to a textblock in the code. You will get to know if that page has been ever executed or not.
A sample code :
WebClient wc = new WebClient();
wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted);
wc.Headers["Content-Type"] = "application/x-www-form-urlencoded";
wc.Encoding = Encoding.UTF8;
Parameters prms = new Parameters();
prms.AddPair("email", email);
prms.AddPair("password", password);
wc.UploadStringAsync(new Uri(loginUrl), "POST", prms.FormPostData(), null);
private void wc_UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
{
// e.Result will contain the page's output
}
// This is my Parameters and Parameter Object classes
public class Parameters
{
public List<ParameterObject> prms;
public Parameters()
{
prms = new List<ParameterObject>();
}
public void AddPair(string id, string val)
{
prms.Add(new ParameterObject(id, val));
}
public String FormPostData()
{
StringBuilder buffer = new StringBuilder();
for (int i = 0; i < prms.Count; i++)
{
if (i == 0)
{
buffer.Append(System.Net.HttpUtility.UrlEncode(prms[i].id) + "=" + System.Net.HttpUtility.UrlEncode(prms[i].value));
}
else
{
buffer.Append("&" + System.Net.HttpUtility.UrlEncode(prms[i].id) + "=" + System.Net.HttpUtility.UrlEncode(prms[i].value));
}
}
return buffer.ToString();
}
}
public class ParameterObject
{
public string id;
public string value;
public ParameterObject(string id, string val)
{
this.id = id;
this.value = val;
}
}

First error: assuming that no error messages means success
Second error: gaping SQL injection holes
first fix: always assume queries will fail, and check for that condition:
$result = mysql_query($query) or die(mysql_error());
second fix: ditch the mysql_() functions and switch to PDO using prepared statements with placeholders. Boom. No more injection problems, and your code won't stop working on you when mysql_() is removed in a future PHP version.
ps..
3rd error: no quotes on your phone number value. So someone submits 867-5309, and you end up inserting -4442 because mysql saw it as two numbers being subtracted, not a string.
