如何登录到WordPress程序？

Question

我需要以编程执行WordPress管理面板一些动作，但不能管理如何使用C＃和HttpWebRequest的登录到WordPress的。

下面是我做的：

private void button1_Click(object sender, EventArgs e)
        {
            string url = "http://localhost/wordpress/wp-login.php";
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            CookieContainer cookies = new CookieContainer();

            SetupRequest(url, request, cookies);
            //request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            //request.Headers["Accept-Language"] = "uk,ru;q=0.8,en-us;q=0.5,en;q=0.3";
            //request.Headers["Accept-Encoding"] = "gzip,deflate";
            //request.Headers["Accept-Charset"] = "windows-1251,utf-8;q=0.7,*;q=0.7";


            string user = "test";
            string pwd = "test";

            request.Credentials = new NetworkCredential(user, pwd);

            string data = string.Format(
                "log={0}&pwd={1}&wp-submit={2}&testcookie=1&redirect_to={3}",
                user, pwd, 
                System.Web.HttpUtility.UrlEncode("Log In"),
                System.Web.HttpUtility.UrlEncode("http://localhost/wordpress/wp-admin/"));

            SetRequestData(request, data);

            ShowResponse(request);
}

private static void SetupRequest(string url, HttpWebRequest request, CookieContainer cookies)
        {
            request.CookieContainer = cookies;
            request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; uk; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)";
            request.KeepAlive = true;
            request.Timeout = 120000;
            request.Method = "POST";
            request.Referer = url;
            request.ContentType = "application/x-www-form-urlencoded";
        }

        private void ShowResponse(HttpWebRequest request)
        {
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            responseTextBox.Text = (((HttpWebResponse)response).StatusDescription);
            responseTextBox.Text += "\r\n";
            StreamReader reader = new StreamReader(response.GetResponseStream());
            responseTextBox.Text += reader.ReadToEnd();
        }

        private static void SetRequestData(HttpWebRequest request, string data)
        {
            byte[] streamData = Encoding.ASCII.GetBytes(data);
            request.ContentLength = streamData.Length;

            Stream dataStream = request.GetRequestStream();
            dataStream.Write(streamData, 0, streamData.Length);
            dataStream.Close();
        }

但不幸的是在性反应，我得到的登录页面的唯一HTML源代码，似乎cookie不包含会话ID。这是我的代码执行后，所有的请求也返回登录页面的HTML源代码，所以我可以假设它不能正确登录。

任何人可以帮助我解决这个问题，或给工作的例子吗？

主要的是扫描在NextGen的画廊插件WordPress的新图像。有没有XML-RPC这样做的方法是什么？

预先感谢。

Answer 1

感谢大家。我设法如何使用插座时，使其只工作。 WordPress的发送数的设置Cookie 头但HttpWebRequest只处理一个这样的报头的实例，以便一些cookie丢失。当使用插座，我可以得到所有需要的饼干和登录到管理面板。

Answer 2

由于WordPress的实施重定向，留下页（重定向）防止从的WebRequest得到适当的cookie中。

为了获取相关的cookie，必须防止重定向。

request.AllowAutoRedirect = false;

不是使用cookie的conatainer登录。

见下面的代码： （基于从阿尔巴哈利的C＃书的一例）

        string loginUri = "http://www.someaddress.com/wp-login.php";
        string username = "username";
        string password = "pass";
        string reqString = "log=" + username + "&pwd=" + password;
        byte[] requestData = Encoding.UTF8.GetBytes(reqString);

        CookieContainer cc = new CookieContainer();
        var request = (HttpWebRequest)WebRequest.Create(loginUri);
        request.Proxy = null;
        request.AllowAutoRedirect = false;
        request.CookieContainer = cc;
        request.Method = "post";

        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = requestData.Length;
        using (Stream s = request.GetRequestStream())
            s.Write(requestData, 0, requestData.Length);

        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        {
            foreach (Cookie c in response.Cookies)
                Console.WriteLine(c.Name + " = " + c.Value);
        }

        string newloginUri = "http://www.someaddress.com/private/";
        HttpWebRequest newrequest = (HttpWebRequest)WebRequest.Create(newloginUri);
        newrequest.Proxy = null;
        newrequest.CookieContainer = cc;
        using (HttpWebResponse newresponse = (HttpWebResponse)newrequest.GetResponse())
        using (Stream resSteam = newresponse.GetResponseStream())
        using (StreamReader sr = new StreamReader(resSteam))
            File.WriteAllText("private.html", sr.ReadToEnd());
        System.Diagnostics.Process.Start("private.html");

我不知道别人会有所帮助，但我只是用WordPress的API登录。我创建了一个用户（CRON_USR）谁“日志中的”晚上的cron作业的一部分，并做了一些工作。 该代码是这样的：

require(dirname(__FILE__) . '/wp-load.php' );
$user = wp_authenticate(CRON_USR, CRON_PWD);
wp_set_auth_cookie($user->ID, true, $secure_cookie); //$secure_cookie is an empty string
do_action('wp_login', CRON_USR);
wp_redirect('http://www.mysite.com/wp-admin/');

Answer 4

NameValueCollection loginData = new NameValueCollection();
loginData.Add("username", "your_username");
loginData.Add("password", "your_password");

WebClient client = new WebClient();
string source = Encoding.UTF8.GetString(client.UploadValues("http://www.site.com/login", loginData));

string cookie = client.ResponseHeaders["Set-Cookie"];

Answer 5

我看不出有什么明显的问题与您的代码，对不起。但WordPress的有一个XML-RPC接口，它有在管理界面中启用。我写了一些Python脚本这个接口和它的工作就像一个魅力。

Answer 6

我想这与我的WordPress.com帐户（具有SSL保护）。我发现，最简单的方法是使用.NET插槽来获得HTTP“设置Cookie”标题，然后解析头到.NET Cookie对象，然后用它来的CookieContainer与饼干的HttpWebRequest的。

最容易通过套接字与SSL工作方式是实施SslStream以上的NetworkStream绑定到套接字。

示例：

private void LogIn()
    {
        string fulladdress = "hostname.wordpress.com";
        string username = HttpUtility.UrlEncode("username");
        string password = HttpUtility.UrlEncode("password");

        string formdata = "log={0}&pwd={1}&redirect_to=http%3A%2F%2F{2}%2Fwp-admin%2F&testcookie=1";
        formdata = string.Format(formdata, username, password, fulladdress);
        IPHostEntry entry = Dns.GetHostEntry(fulladdress);


        Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
        s.Connect(entry.AddressList[0], 443);

        NetworkStream ns = new NetworkStream(s);

        System.Net.Security.SslStream ssl = new System.Net.Security.SslStream(ns);
        byte[] data = Encoding.UTF8.GetBytes(String.Format(WpfApplication2.Properties.Resources.LogRequest, "https://" + fulladdress, fulladdress, form.Length, username, password));

        ssl.AuthenticateAsClient(fulladdress);
        ssl.Write(data, 0, data.Length);

        StringBuilder sb = new StringBuilder();
        byte[] resp = new byte[128];
        int i = 0;
        while (ssl.Read(resp, 0, 128) > 0)
        {
            sb.Append(Encoding.UTF8.GetString(resp));
        }

        List<String> CookieHeaders = new List<string>();
        foreach (string header in sb.ToString().Split("\n\r".ToCharArray(), StringSplitOptions.RemoveEmptyEntries))
        {
            if (header.StartsWith("Set-Cookie"))
            {
                CookieHeaders.Add(header.Replace("Set-Cookie: ", ""));
            }
        }

        CookieContainer jar = new CookieContainer();
        foreach (string cook in CookieHeaders)
        {
            string name, value, path, domain;
            name = value = path = domain = "";

            string[] split = cook.Split(';');
            foreach (string part in split)
            {
                if (part.StartsWith(" path="))
                {
                    path = part.Replace(" path=", "");
                }
                if (part.StartsWith(" domain="))
                {
                    domain = part.Replace(" domain=", "");
                }
                if (!part.StartsWith(" path=") && !part.StartsWith(" domain=") && part.Contains("="))
                {
                    name = part.Split('=')[0];
                    value = part.Split('=')[1];
                }
            }

            jar.Add(new Cookie(name, value, path, domain));
        }

        HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://" + fulladdress + "/wp-admin/index.php");
        req.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3";
        req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        req.KeepAlive = false;
        req.AllowAutoRedirect = false;
        req.Referer = "https://" + fulladdress + "/wp-login.php";
        req.ContentType = "application/x-www-form-urlencoded";
        req.CookieContainer = jar;
        req.AllowAutoRedirect = true;
        req.AutomaticDecompression = DecompressionMethods.GZip;
        req.Method = "GET";
        req.Timeout = 30000;

        HttpWebResponse response = (HttpWebResponse)req.GetResponse();

        using (System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8))
        {
            MessageBox.Show(sr.ReadToEnd());
        }
    }

的代码不是非常有效的，但它示出了登录到管理界面的过程。

希望它能帮助：）

Answer 7

TomerBu对我来说最好的答案，但缺了点什么。

在他的代码，remplace：

 foreach (Cookie c in response.Cookies)
            Console.WriteLine(c.Name + " = " + c.Value);

通过

if (response.Cookies != null)
    {
        foreach (Cookie currentcook in response.Cookies)
             request.CookieContainer.Add(currentcook); //This is the key !!!
    }

接着对即将成为请求，则必须重新使用的CookieContainer。

Answer 8

TomerBu 的回答对我的作品有以下补充。我不得不在网站上安装SSL证书，增加对TLS1.2的支持，并设置用户代理为了这个工作。如果没有TLS1.2，web服务器立即拒绝了我的连接请求。如果没有SSL证书，WordPress网站没有考虑后续WebRequests要记录在我的C＃BOT（即使登录成功）。

***约TLS重要提示：我是一个安全协议的新手，而且只提供我工作。我安装了.NET 4.7.2开发包，并改变了目标框架，我的C＃项目到.NET 4.7.2，但我仍然需要修改ServicePointManager.SecurityProtocol，如下图所示。搜索查找最佳做法，包括更新.NET和按位或运算语句中指定多个TLS版本。

// Add support for TLS 1.2 (note bitwise OR)
ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12;

...
request.Proxy = null;
request.AllowAutoRedirect = false;
request.CookieContainer = cc;
request.Method = "post";

// Add UserAgent
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1";
