I have read and read and played with this code inside out and I still cant work out how to get the refresh token. This in c#
I have tried different combo of access_type, prompt and approval_prompt params.
I keep revoking access by my user to the app, so when the auth code is being requested it does ask for myself to approve the app to be able to access.
I just want to get the refresh token so i can store it and keep refreshing.
here is the code below. I have removed the parts to get the auth code, but if it is needed i can add in. I wonder if anyone can simply spot something simply wrong.
string GetJsonFromAPICall(string p_url,string p_post_data, string p_b64_id_secret)
{
//string C_TOKEN_URL = "https://oauth2.googleapis.com/token";
string l_auth_string = "Basic " + p_b64_id_secret;
print("p_post_data = ", p_url + "?"+p_post_data);
print("Authorization", l_auth_string);
HttpWebRequest request = WebRequest.Create(p_url) as HttpWebRequest;
string postData = p_post_data;// "grant_type=authorization_code&code=" + p_auth_code + "&redirect_uri=" + p_redirect_url;
request.Headers.Add("Authorization", l_auth_string);
var data = Encoding.ASCII.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
print("pos 20 in GetJsonFromAPICall");
print("length ", data.Length.ToString());
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
return responseString;
}
string getAccessToken(string p_b64_id_secret, string p_auth_code, string p_redirect_url)
{
//string l_url = "client_id="+ p_C_GBQ_ONLINE_APP_APP_CLIENT_ID + "&client_secret="+ p_C_GBQ_ONLINE_APP_APP_CLIENT_SECRET + "access_type=offline&prompt=consent&grant_type=authorization_code&code=" + p_auth_code + "&redirect_uri=" + p_redirect_url;
string l_params = "grant_type=authorization_code&code=" + p_auth_code + "&redirect_uri=" + p_redirect_url;
l_params += "&access_type=offline";
l_params += "&prompt=consent";
l_params += "&approval_prompt=force";
//return GetJsonFromAPICall("https://oauth2.googleapis.com/token", l_params, p_b64_id_secret);
return GetJsonFromAPICall("https://www.googleapis.com/oauth2/v4/token", l_params, p_b64_id_secret);
}
var credentials = string.Format("{0}:{1}", C_GBQ_ONLINE_APP_APP_CLIENT_ID, C_GBQ_ONLINE_APP_APP_CLIENT_SECRET_ID);
var b64_id_secret = Convert.ToBase64String(Encoding.UTF8.GetBytes(credentials));
string l_auth_code = "xxxxx"; // worked out successfully earlier
l_json_returned = getAccessToken(p_b64_id_secret, l_auth_code, C_GBQ_ONLINE_APP_REDIRECT_URL);
the returned json is
l_json_returned = : {
"access_token": "FFFFFFFF",
"expires_in": 3569,
"scope": "https://www.googleapis.com/auth/cloud-platform.read-only https://www.googleapis.com/auth/bigquery",
"token_type": "Bearer"
}
While exchanging access_token with google for user consent at GetResponse(), I am receiving this error
The remote server returned an error: (400) Bad Request
My code is:
var postData = "code=" + strCode;
postData += "&" + "client_id=" + ConfigurationManager.AppSettings["ClientId"].ToString();
postData += "&" + "client_secret=" + ConfigurationManager.AppSettings["ClientSecretKey"].ToString();
postData += "&" + "redirect_uri=" + ConfigurationManager.AppSettings["RedirectUrl"].ToString(); /*http://my-domain.com/GoogleOAuth/AccessToken*/
postData += "&" + "grant_type=" + "authorization_code";
var data = Encoding.ASCII.GetBytes(postData);
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://www.googleapis.com/oauth2/v4/token");
httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Method = "POST";
httpWebRequest.ContentLength = data.Length;
httpWebRequest.Headers["Access-Control-Allow-Origin"] = "http://my-domain.com";
using (var stream = httpWebRequest.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var httpResponse = httpWebRequest.GetResponse();
ViewBag.Result = Json(httpResponse);
var responseFromAPI = "";
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
responseFromAPI = streamReader.ReadToEnd();
}
I tried checking my request in, request bin and it looks correct to me as per https://developers.google.com/identity/protocols/OpenIDConnect#server-flow
here is a screenshot of my request
request for access token.
It would be of great help, if anyone can tell me where am i going wrong.
Is there a way to verify my authorization code, because for some reason I feel might be there is a problem with my authorization code.
Do let me know if any more detail is needed.
Thanks.
I cant see how you are applying the post values to the body
https://accounts.google.com/o/oauth2/token
code=4/X9lG6uWd8-MMJPElWggHZRzyFKtp.QubAT_P-GEwePvB8fYmgkJzntDnaiAI&client_id={ClientId}&client_secret={ClientSecret}&redirect_uri=urn:ietf:wg:oauth:2.0:oob&grant_type=authorization_code
They must be in the above format one long html request string. Your content type looks correct.
I am using postmates Delivery Quote API for the last one year, And it is working good by the time when I checked.
But now it seems to be not working
It is throwing an exception with an HTML text with some enable cookies and captcha
I can't understand if i am missing some updates from postmates
Here is my coding
HttpWebRequest req = WebRequest.Create(new Uri("https://api.postmates.com/v1/customers/" + PostmatesCustomerId + "/delivery_quotes")) as HttpWebRequest;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.Headers.Add("Authorization", "Basic " + Base64string);
StringBuilder paramz = new StringBuilder();
paramz.Append("pickup_address=" + PickUpAddress + "&dropoff_address=" + DeliveryAddress);
byte[] formData =
UTF8Encoding.UTF8.GetBytes(paramz.ToString());
req.ContentLength = formData.Length;
// Send the request:
using (Stream post = req.GetRequestStream())
{
post.Write(formData, 0, formData.Length);
}
string responseString = null;
using (HttpWebResponse resp = req.GetResponse()
as HttpWebResponse)
{
StreamReader reader =
new StreamReader(resp.GetResponseStream());
responseString = reader.ReadToEnd();
}
If you're outside of the US, try using a VPN as a workaround to test.
While posting data I am getting issue. The issue is in the & character. I am posting a string which may contain anything. like "this&this, how are you?".
But in the above case only "this" is sending. String from the character & is stripped.
Code I tried:
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://mywebsite.com/import.php");
httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write("tname=sanam&temail=sanam#" + Guid.NewGuid().ToString("N") + ".com&tbody=" + this.body + "&ttitle=" + this.title);
streamWriter.Flush();
streamWriter.Close();
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
retStr = streamReader.ReadToEnd();
}
//retStr = "POST: " + this.body;
}
Does anybody know how to send anything to the server using C#?
Thanks in advance.
Encode the free text fields trough
System.Web.HttpUtility.UrlEncode()
IE:
streamWriter.Write("tname=sanam&temail=sanam#" + Guid.NewGuid().ToString("N") + ".com&tbody=" + HttpUtility.UrlEncode(this.body) + "&ttitle=" + HttpUtility.UrlEncode(this.title));

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
var httpWebRequestPost = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("https://abc.def.org/testAPI/api/TestFile");
httpWebRequestPost.ContentType = "application/json";
httpWebRequestPost.Method = "POST";
bytes = Encoding.UTF8.GetBytes(username + ":" + password);
