400 Bad Request when sending http post request to get token from auth code?

Question

I am trying to access accounts.google.com to get token from authorization code received using HTTP post request.

    var searchurl = "https://accounts.google.com/o/oauth2/token";

    $.ajax({
        dataType: "json",
        url:searchurl,
        data: {code:auth_code, client_id:'client_id', client_secret:'secret', redirect_uri:'http%3A%2F%2Flocalhost:8085%2FGmailIntegration%2FgetAuthResponse1.jsp', grant_type:'authorization_code'},
        type:"Post",
        contentType:"application/x-www-form-urlencoded",
        success:function(data) {
            alert(data);
        },
        error: function(jqXHR, exception) {
            console.log(jqXHR);

        }
    });

Error:

"NetworkError: 400 Bad Request - https://accounts.google.com/o/oauth2/token?
 code=4/PlKII3f0vsPUhl1QNIUXkiIhlfGA.sq9lFf-oCiIcXE-sT2ZLcbRFnpEphQI&client_id={clientid}

here is the document which i am using: After the web server receives the authorization code, it may exchange the authorization code for an access token and a refresh token. This request is an HTTPs post, and includes the following parameters:

Field Description code The authorization code returned from the initial request client_id The client_id obtained during application registration client_secret The client secret obtained during application registration redirect_uri The URI registered with the application grant_type As defined in the OAuth 2.0 specification, this field must contain a value of authorization_code The actual request might look like:

POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded

code=4/P7q7W91a-oMsCeLvIaQm6bTrgtp7&
client_id=8819981768.apps.googleusercontent.com&
client_secret={client_secret}&
redirect_uri=https://oauth2-login-demo.appspot.com/code&
grant_type=authorization_code

A successful response to this request contains the following fields:

Field   Description
access_token    The token that can be sent to a Google API
refresh_token   A token that may be used to obtain a new access token. Refresh tokens are valid until the user revokes access. This field is only present if access_type=offline is included in the authorization code request.
expires_in  The remaining lifetime on the access token
token_type  Indicates the type of token returned. At this time, this field will always have the value Bearer

Thanks. This helped me out. I forgot to add 'charset=utf-8' to the content type and it solved my problem.

Google server expects Json. error in documentation. Send json instead of form encoding. but keep content-type as form-encoded

@pamu Can you post a complete answer. I tried sending json. But no luck.
