Question

我正在尝试将XML数据从一个MVC4服务器（服务器1）发送到另一个（服务器2）

以下简化代码。我的代码可以解决问题 - 调用服务器2方法，但数据似乎没有被传递。

任何想法我做错了（我认为问题的根源是我不理解如何正确转换xml数据以及服务器2应该如何接受它。）

我也尝试过使用client.UploadString和WebRequest（我不想使用它，因为它看起来很麻烦）没有任何成功。

在服务器1中 - 用于将XML数据发送到server2

public void SubmitClicked(String answersJsonStr)
{
    Debug.WriteLine("SubmitClicked() " + answersJsonStr);

    XNode node = JsonConvert.DeserializeXNode(answersJsonStr, "Root");
    var answersXml = node.ToString();
    //This gives: "<Root>\r\n  <question1>answer 1</question1>\r\n</Root>"

    String fullUrl = "http://localhost:61728/SubmitSurveyAnswers";

    WebClient client = new WebClient(); 
    byte[] bret = client.UploadData(fullUrl, "POST",
        System.Text.Encoding.ASCII.GetBytes(answersXml));

    Debug.WriteLine(System.Text.Encoding.ASCII.GetString(bret));
}

server2中控制器中的方法

[HttpPost]
public ActionResult SubmitSurveyAnswers(String answersXml)
{
    Debug.WriteLine("SubmitSurveyAnswers() " + answersXml);
    //answersXML seems to be null
    return Content("answers accepted", "text/html");
}

请注意，server2只是一个模拟模型 - XML的真正接收者将由另一家公司提供。

您好像缺少内容类型标题

public void SubmitClicked(String answersJsonStr)
{
    Debug.WriteLine("SubmitClicked() " + answersJsonStr);

    XNode node = JsonConvert.DeserializeXNode(answersJsonStr, "Root");
    var answersXml = node.ToString();
    //This gives: "<Root>\r\n  <question1>answer 1</question1>\r\n</Root>"

    String fullUrl = "http://localhost:61728/SubmitSurveyAnswers";

    using (WebClient client = new WebClient())
    {
      client.Headers.Add("Content-Type","application/x-www-form-urlencoded");
      byte[] bret = client.UploadData(fullUrl, "POST", System.Text.Encoding.ASCII.GetBytes(answersXml));

      Debug.WriteLine(System.Text.Encoding.ASCII.GetString(bret));
    }
}

Answer 2

这似乎有用......

加入：“answersXml =”+ answersXml，

[ValidateInput（false）]，

加上testydonkey的补充......

public void SubmitClicked(String answersJsonStr)
{
    Debug.WriteLine("SubmitClicked() " + answersJsonStr);

    XNode node = JsonConvert.DeserializeXNode(answersJsonStr, "Root");
    var answersXml = node.ToString();
    //This gives: "<Root>\r\n  <question1>answer 1</question1>\r\n</Root>"

    String fullUrl = "http://localhost:61728/SubmitSurveyAnswers";

    using (WebClient client = new WebClient())
    {
      client.Headers.Add("Content-Type","application/x-www-form-urlencoded");
      byte[] bret = client.UploadData(fullUrl, "POST",
          System.Text.Encoding.ASCII.GetBytes(("answersXml=" + answersXml)));

      Debug.WriteLine(System.Text.Encoding.ASCII.GetString(bret));
    }
}




    [ValidateInput(false)]
    [HttpPost]
    public ActionResult SubmitSurveyAnswers(String answersXml)
    {
        Debug.WriteLine("SubmitSurveyAnswers() " + answersXml);
        return Content("answers accepted ", "text/html");
    }
