C＃ - WebRequest的HTTP POST与曲奇（港从卷曲脚本） [英] c# - WebRequest HTTP POST with Cookie (port from curl script)

问题描述

IBM的RTC REST的API给一个shell脚本示例用于与服务器进行身份验证：

  COOKIES = /饼干.TXT 
 
 USER = my_user 
 PASSWORD = MY_PASSWORD 
主机=https：//开头myJazzServer：9092 /爵士
 
卷曲-k -c $ COOKIES$ HOST /认证/身份
 
卷曲-k -l -b $ COOKIES -c $ COOKIES -d为j_username = $ USER -d为j_password = $ PASSWORD$ HOST /认证/ j_security_check 
  

这完美的作品，但我需要使用C＃与服务器进行身份验证。

到目前为止，我有以下的，但它不工作（返回授权失败页）：

 的CookieContainer _COOKIE; 
 
公共字符串_RTC（）
 {
 HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（https://myJazzServer.com:9092/jazz/authenticated/identity） ; 
如果（_COOKIE == NULL）
 {
 _COOKIE =新的CookieContainer（）; 
} 
串; 
 request.CookieContainer = _COOKIE;使用（VAR响应= request.GetResponse（））
 {
使用
（StreamReader的SR =新的StreamReader（response.GetResponseStream（）））
 {
A = SR .ReadToEnd（）; 
} 
} 
 
 
 
 
字节[]数据=（新ASCIIEncoding（））GetBytes会（为j_username = MYUSER&安培;为j_password =为mypass）; 
 
 =请求（HttpWebRequest的）WebRequest.Create（https://myJazzServer.com:9092/jazz/authenticated/j_security_check）; 
 
 request.Method =POST; 
 request.ContentType =text / html的; 
 request.ContentLength = data.Length; 
 request.CookieContainer = _COOKIE; 
流reqStream = request.GetRequestStream（）; 
 reqStream.Write（数据，0，data.Length）; 
 
线B：使用（VAR响应= request.GetResponse（））
 {
使用
 
（VAR读者=新的StreamReader（response.GetResponseStream（）））
 {
B = reader.ReadToEnd（）; 
} 
} 
} 
  

解决方案

我建议你尝试以下方法：

 公共类WebClientEx：Web客户端
 {
私人的CookieContainer _cookieContainer =新的CookieContainer（）; 
 
保护覆盖的WebRequest GetWebRequest（URI地址）
 {
的WebRequest请求= base.GetWebRequest（地址）; 
如果（请求的HttpWebRequest）
 {
（要求为HttpWebRequest的）.CookieContainer = _cookieContainer; 
} 
返回请求; 
} 
}用
 
类节目
 {
静态无效的主要（）
 {
（VAR的客户=新WebClientEx （））
 {
 VAR response1 = client.DownloadString（https://myJazzServer.com:9092/jazz/authenticated/identity）; 
 
 VAR数据=新的NameValueCollection 
 {
 {为j_username，MYUSER}，
 {为j_password，为mypass}，
 }; 
变种响应2 = client.UploadValues（https://myJazzServer.com:9092/jazz/authenticated/j_security_check数据）; 
 Console.WriteLine（Encoding.Default.GetString（响应2））; 
} 
} 
} 
  

另外要简化调试，你可以通过激活把这个在你的app.config追踪：

 <结构> 
 
<&System.Diagnostics程序GT; 
<来源和GT; 
<信源名称=的System.Net.SocketsTRACEMODE =protocolonly> 
<&听众GT; 
<添加名称=的System.Net.SocketsTYPE =System.Diagnostics.TextWriterTraceListenerinitializeData =network.log/> 
< /听众> 
< /源> 
< /来源> 
 
<开关与GT; 
<添加名称=的System.Net.SocketsVALUE =详细/> 
< /开关> 
 
<跟踪自动冲洗=真/> 
< /system.diagnostics> 
< /结构> 
  

这将创建一个网络活动，这可能会简化调试的详细日志文件。

The IBM RTC RESTful api gives an example of a shell script for authenticating with the server:

COOKIES=./cookies.txt

USER=my_user
PASSWORD=my_password
HOST="https://myJazzServer:9092/jazz"

curl -k -c $COOKIES "$HOST/authenticated/identity"

curl -k -L -b $COOKIES -c $COOKIES -d j_username=$USER -d j_password=$PASSWORD "$HOST/authenticated/j_security_check"

This works perfectly, however i need to authenticate with the server using c#.

So far i have the following, but it isn't working (returns the authorization failed page):

    CookieContainer _cookie;

    public string _RTC()
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://myJazzServer.com:9092/jazz/authenticated/identity");
        if (_cookie == null)
        {
            _cookie = new CookieContainer();
        }
        string a;
        request.CookieContainer = _cookie;
        using (var response = request.GetResponse())
        {
            using (StreamReader sr = new StreamReader(response.GetResponseStream()))
            {
                a = sr.ReadToEnd();
            }
        }




        byte[] data = (new ASCIIEncoding()).GetBytes("j_username=myUser&j_password=MyPass");

        request = (HttpWebRequest)WebRequest.Create("https://myJazzServer.com:9092/jazz/authenticated/j_security_check");

        request.Method = "POST";
        request.ContentType = "text/html";
        request.ContentLength = data.Length;
        request.CookieContainer = _cookie;
        Stream reqStream = request.GetRequestStream();
        reqStream.Write(data,0,data.Length);

        string b;

        using (var response = request.GetResponse())
        {
            using (var reader = new StreamReader(response.GetResponseStream()))
            {
                b = reader.ReadToEnd();
            }
        }
    }

解决方案

I would suggest you try the following:

public class WebClientEx : WebClient
{
    private CookieContainer _cookieContainer = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = _cookieContainer;
        }
        return request;
    }
}

class Program
{
    static void Main()
    {
        using (var client = new WebClientEx())
        {
            var response1 = client.DownloadString("https://myJazzServer.com:9092/jazz/authenticated/identity");

            var data = new NameValueCollection
            {
                { "j_username", "myUser" },
                { "j_password", "MyPass" },
            };
            var response2 = client.UploadValues("https://myJazzServer.com:9092/jazz/authenticated/j_security_check", data);
            Console.WriteLine(Encoding.Default.GetString(response2));
        }
    }
}

Also to simplify debugging you could activate tracing by putting this in your app.config:

<configuration>

  <system.diagnostics>
    <sources>
      <source name="System.Net.Sockets" tracemode="protocolonly">
        <listeners>
          <add name="System.Net.Sockets" type="System.Diagnostics.TextWriterTraceListener" initializeData="network.log" />
        </listeners>
      </source>
    </sources>

    <switches>
      <add name="System.Net.Sockets" value="Verbose"/>
    </switches>

    <trace autoflush="true" />
  </system.diagnostics>
</configuration>

This will create a detailed log file of the network activity which might simplify debugging.
