为什么我得到一个401错误发布到谷歌阅读器API时？阅读器、错误、API、到谷歌

我试图与谷歌阅读器（无证/非官方）从的此页面。我的第一个步骤是获得一个SID和令牌，它工作得很好，但我似乎不能没有得到一个401错误张贴任何。

I'm trying to interface with the Google Reader (undocumented/unofficial) API using information from this page. My first step is to get a SID and token, which works fine, but I can't seem to POST anything without getting a 401 error.

下面是code我用得到我的SID和令牌：

Here is the code I'm using to get my SID and token:

static string getSid()
    {
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://www.google.com/accounts/ClientLogin?service=reader&Email=username&Passwd=password");
        req.Method = "GET";
        string sid;

        HttpWebResponse response = (HttpWebResponse)req.GetResponse();
        using (var stream = response.GetResponseStream())
        {
            StreamReader r = new StreamReader(stream);
            string resp = r.ReadToEnd();

            int indexSid = resp.IndexOf("SID=") + 4;
            int indexLsid = resp.IndexOf("LSID=");
            sid = resp.Substring(indexSid, indexLsid - 5);

            return sid;
        }
    }

和生成cookie并获得令牌：

And to generate a cookie and get the token:

    static Cookie getCookie(string sid)
    {
        Cookie cookie = new Cookie("SID", sid, "/", ".google.com");
        return cookie;
    }

    static string getToken(string sid, Cookie cookie)
    {
        string token;
        string url = "http://www.google.com/reader/api/0/token";

        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.CookieContainer = new CookieContainer();
        req.CookieContainer.Add(cookie);

        HttpWebResponse response = (HttpWebResponse)req.GetResponse();
        using (var stream = response.GetResponseStream())
        {
            StreamReader r = new StreamReader(stream);
            token = r.ReadToEnd();
            return token;
        }
    }

现在，如果我尝试做一个POST使用以下（在本例中，插入一个新的标签），我得到的401错误。

Now if I try to do a POST (in this example, insert a new tag) using the following, I get the 401 error.

    static void insertTag(string tag, Cookie cookie)
    {
        string result = "";
        string data = Uri.EscapeDataString("a="+tag+"&T=" + Program.token);

        byte[] buffer = Encoding.GetEncoding(1252).GetBytes(data);
        HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create
            ("http://www.google.com/reader/api/0/edit-tag?client=-");
        WebReq.Method = "POST";

        WebReq.Credentials = new NetworkCredential("username", "password");


        WebReq.ContentType = "application/x-www-form-urlencoded";
        WebReq.ContentLength = buffer.Length;

        Stream PostData = WebReq.GetRequestStream();

        PostData.Write(buffer, 0, buffer.Length);
        PostData.Close();

        HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
        Stream Answer = WebResp.GetResponseStream();
        StreamReader _Answer = new StreamReader(Answer);
        result = _Answer.ReadToEnd();

        if (result.Length < 0)
            result = "";
    }

上线时，会出现错误流答案= WebResp.GetResponseStream（）;
