I'm trying to figure out how to post a new task to a user in asana, but I keep getting the 400 error code. Can anyone tell me what I am doing wrong.
This is what I have so far:
string apiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string ID = "xxxxxxxxxxxxx";
string url = #"https://app.asana.com/api/1.0/tasks";
Data dat = new Data();
dat.workspace = ID;
dat.name = "Buy eggs";
dat.notes = "Testing";
string json = JsonConvert.SerializeObject(dat);
string data ="\"data\": " + json;
byte[] bytes = Encoding.UTF8.GetBytes(data);
var req = (HttpWebRequest)WebRequest.Create(url);
Console.WriteLine(bytes.ToString());
req.Method = WebRequestMethods.Http.Post;
req.ContentLength = bytes.Length;
req.ContentType = "application/json";
var authInfo = apiKey + ":";
var encodedAuthInfo = Convert.ToBase64String(
Encoding.Default.GetBytes(authInfo));
req.Headers.Add("Authorization", "Basic " + encodedAuthInfo);
req.ContentLength = bytes.Length;
Stream reqStream = req.GetRequestStream();
reqStream.Write(bytes, 0, bytes.Length);
reqStream.Close();
try
{
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
string res = new StreamReader(response.GetResponseStream()).ReadToEnd();
Console.WriteLine(res);
Console.ReadLine();
}
catch (WebException ex)
{
HttpWebResponse response = ((HttpWebResponse)ex.Response);
string e = url + " caused a " + (int)response.StatusCode + " error.\n" + response.StatusDescription;
Console.WriteLine(e);
Console.ReadLine();
}
I put the serial converter, did i do it wrong?
As the first comment points out, you need to serialize the data properly. The final body posted should look something like:
{ "data": { "name": "My Example Task", ... }}
(Except of course with the ... replaced with more fields.)
I have researched a long and found below code useful and working. I can successfully post Task to Asana through my application. I have used Json serializer for dot net. Thanks to Newtonsoft.Json.
string json = null;
byte[] bytes = null;
string url = "https://app.asana.com/api/1.0/tasks";
HttpWebRequest req = default(HttpWebRequest);
Stream reqStream = default(Stream);
string authInfo = null;
Task TaskData = new Task();
try
{
authInfo = apiKey + Convert.ToString(":");
TaskData.workspace = WorkspaceId;
TaskData.name = TaskName;
TaskData.notes = TaskNotes;
json = JsonConvert.SerializeObject(TaskData);
json = json.Insert((json.Length - 1), ",\"projects\":[" + ProjectId + "]");
json = Convert.ToString("{ \"data\":") + json + "}";
bytes = Encoding.UTF8.GetBytes(json);
req = (HttpWebRequest)WebRequest.Create(url);
req.Method = WebRequestMethods.Http.Post;
req.ContentType = "application/json";
req.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)));
req.ContentLength = bytes.Length;
reqStream = req.GetRequestStream();
reqStream.Write(bytes, 0, bytes.Length);
reqStream.Close();
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
string res = new StreamReader(response.GetResponseStream()).ReadToEnd();
Console.WriteLine(res);
Console.ReadLine();
string finalString = res.Remove(0, 8);
finalString = finalString.Remove((finalString.Length - 1));
AsanaObjectId newtask = JsonConvert.DeserializeObject<AsanaObjectId>(finalString);
return newtask;
}
catch (WebException ex)
{
HttpWebResponse response = (HttpWebResponse)ex.Response;
string resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();
MessageBox.Show(resp);
System.Environment.Exit(0);
}

I have following code which give "Error:MissingRegistration" response from GCM server.
public void SendPushNotification()
{

But exact string returned by 'postData' posted by Postman or Fiddler gives positive response and notification arrived at device.
What I'm missing in my code please help me.
The postData returns this value which successfully posted by Postman And Fiddler
{"collapse_key":"score_update","time_to_live":108,"delay_while_idle":true,"data": { "message" : "Hello","time": "5/13/2016 5:50:59 PM"},"registration_ids":["cXMf6hkYIrw:APA91bGr-8y2Gy-qzNJ3zjrlf8t-4m9uDib9P0j8GW87bH5jq891-x_7P0qqItzlc_HXh11Arg76lCOcjXPrU9LAgtYLwllH2ySxA0ADSfiz3qPolajjvI3d3zE6Rh77dwRqXn3NnbAm"]}
The problem in your code is in ContentType
Instead of using this:-
Request.ContentType = "application/json";
Use
tRequest.ContentType = "application/json";
It will work
Try This:-
private string SendGCMNotification()
{
try
{
string message = "some test message";
//string tickerText = "example test GCM";
string contentTitle = "content title GCM";
string registration_id = "cXMf6hkYIrw:APA91bGr-8y2Gy-qzNJ3zjrlf8t-4m9uDib9P0j8GW87bH5jq891-x_7P0qqItzlc_HXh11Arg76lCOcjXPrU9LAgtYLwllH2ySxA0ADSfiz3qPolajjvI3d3zE6Rh77dwRqXn3NnbAm";
string postData =
"{ \"registration_ids\": [ \"" + registration_id + "\" ], " +
"\"data\": {\"contentTitle\":\"" + contentTitle + "\", " +
"\"message\": \"" + message + "\"}}";
string GoogleAppID = "AIzaSyA2Wkdnp__rBokCmyloMFfENchJQb59tX8";
WebRequest wRequest;
wRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
wRequest.Method = "POST";
wRequest.ContentType = " application/json;charset=UTF-8";
wRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
var bytes = Encoding.UTF8.GetBytes(postData);
wRequest.ContentLength = bytes.Length;
var stream = wRequest.GetRequestStream();
stream.Write(bytes, 0, bytes.Length);
stream.Close();
var wResponse = wRequest.GetResponse();
stream = wResponse.GetResponseStream();
var reader = new StreamReader(stream);
var response = reader.ReadToEnd();
var httpResponse = (HttpWebResponse)wResponse;
var status = httpResponse.StatusCode.ToString();
reader.Close();
stream.Close();
wResponse.Close();
//TODO check status
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
return "sent";
}
The problem with this code is that the file, once it is uploaded, is not the correct format. I'm trying to upload a .zip file.

NetworkCredential credentials = new NetworkCredential("username", "password");
webRequest.Credentials = credentials;
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(parameter);
Stream os = null;
try
{ // send the Post
webRequest.ContentLength = bytes.Length; //Count bytes to send
os = webRequest.GetRequestStream();
os.Write(bytes, 0, bytes.Length); //Send it
}
catch (WebException ex)
{
MessageBox.Show(ex.Message, "HttpPost: Request error",

How to post JSON to a server using C#?
(15 answers)
Closed 1 year ago.
I am trying to make a json call using C#. I made a stab at creating a call, but it did not work:
public bool SendAnSMSMessage(string message)
{
HttpWebRequest request = (HttpWebRequest)
WebRequest.Create("http://api.pennysms.com/jsonrpc");
request.Method = "POST";
request.ContentType = "application/json";
string json = "{ \"method\": \"send\", "+
" \"params\": [ "+
" \"IPutAGuidHere\", "+
" \"msg#MyCompany.com\", "+
" \"MyTenDigitNumberWasHere\", "+
" \""+message+"\" " +
" ] "+
"}";
StreamWriter writer = new StreamWriter(request.GetRequestStream());
writer.Write(json);
writer.Close();
return true;
}
Any advice on how to make this work would be appreciated.
In your code you don't get the HttpResponse, so you won't see what the server side sends you back.
you need to get the Response similar to the way you get (make) the Request. So
public static bool SendAnSMSMessage(string message)
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{ \"method\": \"send\", " +
" \"params\": [ " +
" \"IPutAGuidHere\", " +
" \"msg#MyCompany.com\", " +
" \"MyTenDigitNumberWasHere\", " +
" \"" + message + "\" " +
" ] " +
"}";
streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
//Now you have your response.
//or false depending on information in the response
return true;
}
}
I also notice in the pennysms documentation that they expect a content type of "text/json" and not "application/json". That may not make a difference, but it's worth trying in case it doesn't work.
just continuing what #Mulki made with his code
public string WebRequestinJson(string url, string postData)
{
string ret = string.Empty;
StreamWriter requestWriter;
var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
HttpWebResponse resp = (HttpWebResponse)webRequest.GetResponse();
Stream resStream = resp.GetResponseStream();
StreamReader reader = new StreamReader(resStream);
ret = reader.ReadToEnd();
return ret;
}
Here's a variation of Shiv Kumar's answer, using Newtonsoft.Json (aka Json.NET):
public static bool SendAnSMSMessage(string message)
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
var serializer = new Newtonsoft.Json.JsonSerializer();
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
using (var tw = new Newtonsoft.Json.JsonTextWriter(streamWriter))
{
serializer.Serialize(tw,
new {method= "send",
#params = new string[]{
"IPutAGuidHere",
"msg#MyCompany.com",
"MyTenDigitNumberWasHere",
message
}});
}
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
//Now you have your response.
//or false depending on information in the response
return true;
}
}
If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json
Json(someDictionaryObj, JsonRequestBehavior.AllowGet);
Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5
as for your web request...it seems ok at first glance..
I would use something like this..
public void WebRequestinJson(string url, string postData)
{
StreamWriter requestWriter;
var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
}
May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.
Its just a sample of how to post Json data and get Json data to/from a Rest API in BIDS 2008 using System.Net.WebRequest and without using newtonsoft. This is just a sample code and definitely can be fine tuned (well tested and it works and serves my test purpose like a charm). Its just to give you an Idea. I wanted this thread but couldn't find hence posting this.These were my major sources from where I pulled this.

Code that works(unit tested)
//Get Example
var httpWebRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("https://abc.def.org/testAPI/api/TestFile");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "GET";
var username = "usernameForYourApi";
var password = "passwordForYourApi";
var bytes = Encoding.UTF8.GetBytes(username + ":" + password);
httpWebRequest.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(bytes));
var httpResponse = (System.Net.HttpWebResponse)httpWebRequest.GetResponse();
using (StreamReader streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
string result = streamReader.ReadToEnd();
Dts.Events.FireInformation(3, "result from readng stream", result, "", 0, ref fireagain);
}
//Post Example
