POST操作JSON通过在C＃中的WebClient URL [英] POSTing JSON to URL via WebClient in C#

问题描述

我有一些JavaScript code，我需要转换为C＃。我的JavaScript code的POST一些JSON到一个已经创建了一个Web服务。这个JavaScript code工作正常，如下所示：

I have some JavaScript code that I need to convert to C#. My JavaScript code POSTs some JSON to a web service that's been created. This JavaScript code works fine and looks like the following:

var vm = { k: "1", a: "2", c: "3", v: "4" };
$.ajax({
  url: "http://www.mysite.com/1.0/service/action",
  type: "POST",
  data: JSON.stringify(vm),
  contentType: "application/json;charset=utf-8",
  success: action_Succeeded,
  error: action_Failed
});

function action_Succeeded(r) {
  console.log(r);
}

function log_Failed(r1, r2, r3) {
  alert("fail");
}

我试图找出如何将其转换为C＃。我的应用程序是使用.NET 2.0。从我可以告诉，我需要做类似如下：

I'm trying to figure out how to convert this to C#. My app is using .NET 2.0. From what I can tell, I need to do something like the following:

using (WebClient client = new WebClient())
{
  string json = "?";
  client.UploadString("http://www.mysite.com/1.0/service/action", json);
}

我有点停留在这一点上。我不知道是什么 JSON 应该像。我不知道我是否需要设置的内容类型。如果我这样做，我不知道该怎么做。我也看到 UploadData 。所以，我不知道如果我即使使用正确的方法。从某种意义上说，我的数据的序列化是我的问题。

I'm a little stuck at this point. I'm not sure what json should look like. I'm not sure if I need to set the content type. If I do, I'm not sure how to do that. I also saw UploadData. So, I'm not sure if I'm even using the right method. In a sense, the serialization of my data is my problem.

谁能告诉我什么，我在这里丢失？

Can someone tell me what I'm missing here?

感谢您！

推荐答案

您需要一个JSON序列来分析你的内容，很可能你已经拥有它，
您如何使一个请求最初的问题，这可能是一个想法：

You need a json serializer to parse your content, probably you already have it, for your initial question on how to make a request, this might be an idea:

        var baseAddress = "http://www.mysite.com/1.0/service/action";

        var http = (HttpWebRequest)WebRequest.Create(new Uri(baseAddress));
        http.Accept = "application/json";
        http.ContentType = "application/json";
        http.Method = "POST";

        string parsedContent = <<PUT HERE YOUR JSON PARSED CONTENT>>;
        ASCIIEncoding encoding = new ASCIIEncoding();
        Byte[] bytes = encoding.GetBytes(parsedContent);

        Stream newStream = http.GetRequestStream();
        newStream.Write(bytes, 0, bytes.Length);
        newStream.Close();

        var response = http.GetResponse();

        var stream = response.GetResponseStream();
        var sr = new StreamReader(stream);
        var content = sr.ReadToEnd();
