如何写一个HTTP请求 [英] How to write a HTTP Request

问题描述

您好，我试着写在C＃（POST）一个HTTP请求，但我需要一个错误帮助

Hello I try to write a HTTP Request in C# (Post), but I need help with an error

EXPL：我想送DLC的内容文件到服务器和recive解密的内容。

Expl: I want to send the Content of a DLC File to the Server and recive the decrypted content.

C＃代码

public static void decryptContainer(string dlc_content) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://dcrypt.it/decrypt/paste");
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    request.Accept = "Accept=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

    using (StreamWriter writer = new StreamWriter(request.GetRequestStream(), Encoding.ASCII))
    {
        writer.Write("content=" + dlc_content);
    }

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

    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
    {
        Console.WriteLine(reader.ReadToEnd());
    }
}

在这里我得到了HTML请求

and here I got the html request

<form action="/decrypt/paste" method="post">
    <fieldset>
        <p class="formrow">
          <label for="content">DLC content</label>
          <input id="content" name="content" type="text" value="" />
         </p>
        <p class="buttonrow"><button type="submit">Submit »</button></p>
    </fieldset>
</form>

错误消息：

Error Message:

{
    "form_errors": {
      "__all__": [
        "Sorry, an error occurred while processing the container."
       ]
    }
}

是，如果一个人非常有益可以帮我解决这个问题！

Would be very helpfull if someone could help me solving the problem!

推荐答案

您没有设置内容长度，这可能会导致问题。您也可以尝试直接写入字节流的转换，而不是它第一次为ASCII。（这样做是为了你如何在此刻做相反的方式），如：

You haven't set a content-length, which might cause issues. You could also try writing bytes directly to the stream instead of converting it to ASCII first.. (do it the opposite way to how you're doing it at the moment), eg:

public static void decryptContainer(string dlc_content) 
   {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://dcrypt.it/decrypt/paste");
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.Accept = "Accept=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

        byte[] _byteVersion = Encoding.ASCII.GetBytes(string.Concat("content=", dlc_content));

        request.ContentLength = _byteVersion.Length

        Stream stream = request.GetRequestStream();
        stream.Write(_byteVersion, 0, _byteVersion.Length);
        stream.Close();

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

        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            Console.WriteLine(reader.ReadToEnd());
        }
    }

我个人认为发布像这是一个在过去位fidgity。您也可以尝试设置上的要求ProtocolVersion。

I've personally found posting like this to be a bit "fidgity" in the past. You could also try setting the ProtocolVersion on the request.
