OData POST request returning 403 forbidden

Posted on Jun 24, 2013 at 10:50 AM 2.2k Views

Hi All,

I am trying to make a POST request from windows mobile 6.5 through SUP; I have included the headers X-CSRF-Token and X-SUP-APPCID. Please help me to correct the error in my code.

HttpWebRequest request =

(HttpWebRequest)HttpWebRequest.Create(url);

request.Credentials = cache;

request.Method = "POST";

request.ContentType = "application/atom+xml";

request.Accept = "application/xml,application/atom+xml";

request.AllowWriteStreamBuffering = true;

request.Headers.Add("X-SUP-SC", "Security1");

request.Headers.Add("X-CSRF-Token", XCSRFToken);

request.Headers.Add("X-SUP-APPCID", ApplicationConnectionID);

request.Headers.Add("X-SUP-URLREWRITE-ENABLED", "False");

request.Headers.Add("Set-Cookie", strCookie);

byte[] bytes = Encoding.UTF8.GetBytes(postData);

request.ContentLength = bytes.Length;

using (Stream putStream = request.GetRequestStream())

{

putStream.Write(bytes, 0, bytes.Length);

putStream.Close();

}

` WebResponse response = request.GetResponse();

    I resolved the issue by formatting the cookie which is returning from the response.

    What is the error you are getting?

    Are you passing the token and cookie correctly ?

      Hi ,

      Thanks for your response. Stack Trace is given below.

      Before post request I send GET request and stored the XCSRF token and cookie as below

      strXCSRFToken = response.Headers["X-CSRF-Token"];

      strCookie =response.Headers["Set-Cookie"];

      {System.Net.WebException: The remote server returned an error: (403) Forbidden.

    I believe that you are requesting a bad url.

    Please try the POST method in firefox restclient and make sure that the POST is working.

    Try removing these two lines from the request:

    request.ContentType = "application/atom+xml";

    request.Accept = "application/xml,application/atom+xml";

    If I remember on the JavaScript side for WM 6.5, above two lines caused issues. I would imagine the same code is being used when you try to do the same thing from C#.

    Hi,

    Try Adding this additional header.

    X-Requested-With : XMLHttpRequest

    and check if it works.

    Best Regards,

    Sujith

    Hi All,

    i am develoing a native iOS application where I am trying to consume Odata services through Sybase Mobile Platform 2.3 and Relay server.

    I have tested my Odata service url in rest client also and its working fine.

    In my iOS code I am able to fetch the application end point but while fetching the service document I am getting this error SUPJsonException:expected string, found 173/Location:-[ODPRequest startSynchronous].

    My code is

    NSString *urlStr = [ODPAppSettings getApplicationEndpointWithError:&error];

    NSURL *urlNew = [NSURL URLWithString:urlStr];

    [SDMRequestBuilder enableXCSRF:YES];

    id<SDMRequesting> request = [SDMRequestBuilder requestWithURL:urlNew];

    [request setRequestMethod:@"GET"];

    [request setUsername:@"xxxxxx"];

    [request setPassword:@"xxxxxx"];

    [request addRequestHeader:@"Content-Type" value:@"application/atom+xml;type=entry"];

    [request addRequestHeader:@"X-Requested-With" value:@"XMLHttpRequest"];

    [request startSynchronous];


    My netweaver server version is 7.4. Could anyone please help me to resolve this issue.



    With Regards
