获取facebook用户令牌

Question

我试图通过这样做来检索facebook用户令牌.我知道它可以在python中完成.

    public string GetToken(string Username, string Password)
    {
        wb.DownloadData("https://login.facebook.com/login.php?login_attempt=1");
        var data = new NameValueCollection();
        data["email"] = UserName;
        data["pass"] = Password;
        byte[] responsebytes = wb.UploadValues("https://login.facebook.com/login.php?login_attempt=1", "POST", data);
       string responsebody = Encoding.UTF8.GetString(wb.("https://www.facebook.com/dialog/oauth?client_id=282892925078054&redirect_uri=https://www.facebook.com/&response_type=token"));
        Console.WriteLine(responsebody);

        return responsebody;
    }

但它没有返回令牌.我知道它可以做到,因为我已经在python中看到了这一点.还有一种从这里获取用户ID的简单方法吗？

编辑:

这是在python中完成的:

def get_token(self, username, password):
    self.session.get("https://login.facebook.com/login.php?login_attempt=1")
    self.session.post("https://login.facebook.com/login.php?login_attempt=1", data={'email': username, 'pass': password})    
    return self.session.get("https://www.facebook.com/dialog/oauth?client_id=282892925078054&redirect_uri=https://www.facebook.com/&response_type=token").url.split("=")[1].split("&")[0]

好的,我到目前为止.

        //Login to facebook.
        string formUrl = "https://login.facebook.com/login.php?login_attempt=1"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag
        string formParams = string.Format("email_address={0}&password={1}", email, pass);
        string cookieHeader;
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(formUrl);
        req.ContentType = "application/x-www-form-urlencoded";
        req.Method = "POST";
        byte[] bytes = Encoding.ASCII.GetBytes(formParams);
        req.ContentLength = bytes.Length;
        using (Stream os = req.GetRequestStream())
        {
            os.Write(bytes, 0, bytes.Length);
        }
        WebResponse resp = req.GetResponse();
        cookieHeader = resp.Headers["Set-cookie"];
        Console.WriteLine(cookieHeader);
        Console.WriteLine();
        //Get token
        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("https://www.facebook.com/dialog/oauth?client_id=282892925078054&redirect_uri=https://www.facebook.com/&response_type=token");
        webRequest.Headers.Add("Cookie", cookieHeader);
        //webRequest.AllowAutoRedirect = false;
        HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
        string redirectUrl = response.Headers.Get("Location");

        Console.WriteLine(redirectUrl);

但它并没有给我正确的URL.我究竟做错了什么？

编辑:我尝试过AllowautoRedirect true/false.如果为false,则返回此URL. https://www.facebook.com/login.php?api_key=282892925078054&skip_api_login=1&display=page&cancel_url=https%3A%2F%2Fwww.facebook.com%2F%3Ferror_reason%3Duser_denied%26error%3Daccess_denied%26error_description%3DThe%2Buser% 2Bdenied%2Byour%2Brequest.&fbconnect = 1&下一= HTTPS%3A%2F%2Fwww.facebook.com%2Fdialog%2Fpermissions.request%3F_path%3Dpermissions.request%26app_id%3D282892925078054%26client_id%3D282892925078054%26redirect_uri%3Dhttps%253A%252F% 252Fwww.facebook.com%252F%26display%3Dpage%26response_type%3Dtoken%26fbconnect%3D1%26from_login%3D1&RCOUNT = 1

我期待这样的事情:

除非你想自己重写这个库，否则你可以使用Facebook C# SDK，这就是注册你的appKey和appId。

看一下：https ://github.com/facebook-csharp-sdk/facebook-winclient-sdk
