Question

我正在尝试创建/修改dotclear博客。

对于大多数选项，我使用XmlRpc API（DotClear.MetaWeblog）。但我没有找到办法处理类别。

所以我开始查看Http数据包并尝试“与浏览器相同”。

这是我用来“Http POST”的方法

protected HttpStatusCode HttpPost(Uri url_, string data_, bool allowAutoRedirect_)
{
    HttpWebRequest Request;
    HttpWebResponse Response = null;
    Stream ResponseStream = null;
    Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(url_);
    Request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)";
    Request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
    Request.AllowAutoRedirect = allowAutoRedirect_;
    // Add the network credentials to the request.
    Request.Credentials = new NetworkCredential(Username, Password);

    string authInfo = Username + ":" + Password;
    authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
    Request.Headers["Authorization"] = "Basic " + authInfo; 

    Request.Method = "POST";
    Request.CookieContainer = Cookies;
    if(ConnectionCookie!=null)
        Request.CookieContainer.Add(url_, ConnectionCookie);
    if (dcAdminCookie != null)
        Request.CookieContainer.Add(url_, dcAdminCookie);
    Request.PreAuthenticate = true;

    ASCIIEncoding encoding = new ASCIIEncoding();
    string postData = data_;
    byte[] data = encoding.GetBytes(postData); //Encoding.UTF8.GetBytes(data_);  //encoding.GetBytes(postData);
    Request.ContentLength = data.Length;
    Request.ContentType = "application/x-www-form-urlencoded";
    Stream newStream = Request.GetRequestStream();
    // Send the data.
    newStream.Write(data, 0, data.Length);
    newStream.Close();

    try
    {
        // get the response from the server.
        Response = (HttpWebResponse)Request.GetResponse();
        if (!allowAutoRedirect_)
        {
            foreach (Cookie c in Response.Cookies)
            {
                if (c.Name == "dcxd")
                    ConnectionCookie = c;
                if (c.Name == "dc_admin")
                    dcAdminCookie = c;

            }

            Cookies.Add(Response.Cookies);
        }
        // Get the response stream.
        ResponseStream = Response.GetResponseStream();
        // Pipes the stream to a higher level stream reader with the required encoding format. 
        StreamReader readStream = new StreamReader(ResponseStream, Encoding.UTF8);
        string result = readStream.ReadToEnd();

        if (Request.RequestUri == Response.ResponseUri)
        {
            _log.InfoFormat("{0} ==> {1}({2})", Request.RequestUri, Response.StatusCode, Response.StatusDescription);
        }
        else
        {
            _log.WarnFormat("RequestUri:{0}\r\nResponseUri:{1}\r\nstatus code:{2} Status descr:{3}", Request.RequestUri, Response.ResponseUri, Response.StatusCode, Response.StatusDescription);
        }
    }
    catch (WebException wex)
    {
        Response = wex.Response as HttpWebResponse;

        if (Response != null)
        {
            _log.ErrorFormat("{0} ==> {1}({2})", Request.RequestUri, Response.StatusCode, Response.StatusDescription);
        }

        Request.Abort();
    }
    finally
    {
        if (Response != null)
        { 
            // Releases the resources of the response.
            Response.Close();
        }

    }
    if(Response !=null)
        return Response.StatusCode;

    return HttpStatusCode.Ambiguous;
}

所以要做的第一件事就是以管理员身份进行身份验证。这是代码：

protected bool HttpAuthenticate()
{
    Uri u = new Uri(this.Url);
    Uri url = new Uri(string.Format("{0}/admin/auth.php", u.GetLeftPart(UriPartial.Authority)));
    string data = string.Format("user_id={0}&user_pwd={1}&user_remember=1", Username, Password);
    var ret = HttpPost(url,data,false);
    return (ret == HttpStatusCode.OK || ret==HttpStatusCode.Found);
}

现在我已通过身份验证，我需要获取xd_chek信息（我可以在页面上找到，所以基本上它是/admin/category.php +正则表达式{{1}上的GET }））
因此我已通过身份验证并拥有dotclear[.]nonce = '(.*)'信息。最后要做的事情似乎是发布下一个类别。但当然它根本不起作用......这是代码：
```
xd_check
```

我哪里错了？

最终我找到了解决方案。

似乎在认证和使用页面之间丢失了cookie。

所以我决定不使用框架的de CookiesContainer，而只是将cookie保存在字符串中并在每次请求时传递它们。

它很棒！

代码示例：

private string _cookieAsString = string.Empty;

    protected string CookieAsString
    {
        get { return _cookieAsString; }
        set
        {
            if (value != null)
            {
                if (!_cookieAsString.Contains(value))
                {
                    if (_cookieAsString.Length == 0)
                        _cookieAsString = value;
                    else
                        _cookieAsString += string.Format(";{0}", value);
                }
            }
        }
    }

在HttpWebRequest中，我这样设置：

...
Request.Headers.Add(HttpRequestHeader.Cookie, CookieAsString);
...

将cookie保存在httpWebRequest中，如下所示：

...
CookieAsString = Response.Headers[HttpResponseHeader.SetCookie];
...
