链接的API（身份验证令牌（oauth2））c＃.net

我想知道是否有人可以给我一些使用API中的链接的指示。我以为我很怀疑，但是由于某种原因，当尝试获取auth_token时，我只是收到了HTTP 400错误请求。

我的代码就是：

public string redirectUrl = URLTOREDIRECT;

public String apiKey = APIKEY;

public String apiSecret = APISECRET;

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        if (Request.QueryString["code"] != null)
        {
            VerifyAuthentication(Request.QueryString["code"]);
        }
    }
}

protected void Button1_Click(object sender, EventArgs e)
{

        Response.Redirect("https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=apiKey&scope=rw_company_admin&state=DCEEFWF45453sdffef424&redirect_uri=" + HttpUtility.HtmlEncode(redirectUrl));

}

public String VerifyAuthentication(string code)
{
   string authUrl = "https://www.linkedin.com/uas/oauth2/accessToken";

    var sign = "grant_type=authorization_code" + "&code=" + code + "&redirect_uri=" + HttpUtility.HtmlEncode(redirectUrl) + "&client_id=" + _consumerkey + "&client_secret=" + _consumerSecret;
   // var postData = String.Format("grant_type=authorization_code&code={0}&redirect_uri={1}&client_id={2}&client_secret={3}", code, HttpUtility.HtmlEncode(redirectUrl), apiKey, apiSecret);

    HttpWebRequest webRequest = WebRequest.Create(authUrl + "?" + sign) as HttpWebRequest;
    webRequest.Method = "POST";

    //This "application/x-www-form-urlencoded"; line is important
    webRequest.ContentType = "application/x-www-form-urlencoded";

    webRequest.ContentLength = sign.Length;

    StreamWriter requestWriter = new StreamWriter(webRequest.GetRequestStream());
    requestWriter.Write(sign);
    requestWriter.Close();

    StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());

    return responseReader.ReadToEnd().ToString() ;
}

出于测试目的，代码全部位于同一页面中，并且与redirectUrl位于同一页面中。

真的很困惑，尝试了所有变化。

当我被定向链接到允许应用程序时，第一位显然很有效。第二部分获取身份验证令牌失败。

经过长时间的挠头，尤里卡时刻-不需要发送请求中的信息。

    string authUrl = "https://www.linkedin.com/uas/oauth2/accessToken";

    var sign = "grant_type=authorization_code&code=" + HttpUtility.UrlEncode(code) + "&redirect_uri=" + HttpUtility.HtmlEncode(redirectUrl) + "&client_id=" + apiKey + "&client_secret=" + apiSecret;
    //byte[] byteArray = Encoding.UTF8.GetBytes(sign);


    HttpWebRequest webRequest = WebRequest.Create(authUrl + "?" + sign) as HttpWebRequest;
    webRequest.Method = "POST";
    webRequest.ContentType = "application/x-www-form-urlencoded";

    Stream dataStream = webRequest.GetRequestStream();

    String postData = String.Empty;
    byte[] postArray = Encoding.ASCII.GetBytes(postData);

    dataStream.Write(postArray, 0, postArray.Length);
    dataStream.Close();

    WebResponse response = webRequest.GetResponse();
    dataStream = response.GetResponseStream();


    StreamReader responseReader = new StreamReader(dataStream);
    String returnVal = responseReader.ReadToEnd().ToString();
    responseReader.Close();
    dataStream.Close();
    response.Close();
    return returnVal;
