我正在尝试在 C# 上检索 JSON 对象，这是我的 JavasSciprt 帖子，但我无法在代码隐藏中处理它，谢谢！

$.ajax({
    type: "POST",
    url: "facebook/addfriends.aspx",
    data: { "data": response.data },
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (msg) {
        location = '/facebook/login?URL=' + ReturnURL + '&UID=' + response.authResponse.userID + '&TK=' + response.authResponse.accessToken + '';
    }
});

我试图检索如下数据：

Request.Form["data"]
Request["data"]

这是来自Encosia.com的示例（我添加了一个表单参数）。您不需要访问Page.Form- 您可以使用方法参数来代替。

代码隐藏

public partial class _Default : Page 
{
  [WebMethod]
  public static string GetDate(string someParameter)
  {
    return DateTime.Now.ToString();
  }
}

Javascript

$(document).ready(function() {
  // Add the page method call as an onclick handler for the div.
  $("#Result").click(function() {
    $.ajax({
      type: "POST",
      url: "Default.aspx/GetDate",
      data: {someParameter: "some value"},
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(msg) {
        // Replace the div's content with the page method's return.
        $("#Result").text(msg.d);
      }
    });
  });
});

我就是这样做的，它对我有用：

$.ajax({
    type: "POST",
    url: "facebook/addfriends.aspx",
    data: "data=" + response.data + "&data1=anyothervaluelikethis",
    contentType: "application/x-www-form-urlencoded",
    dataType: "json",
    success: function (msg) {
        location = '/facebook/login?URL=' + ReturnURL + '&UID=' + response.authResponse.userID + '&TK=' + response.authResponse.accessToken + '';
    }
});

这两行被修改

 data: "data=" + response.data + "&data1=anyothervaluelikethis",
 contentType: "application/x-www-form-urlencoded",

代码隐藏 C# 方法签名应类似于：

[WebInvoke(UriTemplate = "MyMethod", Method = "POST", ResponseFormat = WebMessageFormat.Json)]
public Object MyMethod(Object data){
 // your code
}

其中 Object 可以是任何可序列化的类
