如何让一个ASMX文件输出JSON [英] How to let an ASMX file output JSON

问题描述

我创建了身后文件code的ASMX文件。它的工作很好，但它正在输出XML。

不过，我需要它输出JSON。该ResponseFormat配置似乎并没有工作。我的code-背后是：

  [System.Web.Script.Services.ScriptService]
公共类_default：System.Web.Services.WebService {
    [的WebMethod]
    [ScriptMethod（UseHttpGet = TRUE，ResponseFormat = ResponseFormat.Json）
    公共字符串[]的UserDetails（）
    {
        返回新的字符串[] {ABC，高清};
    }
}
 

解决方案

返回即使R​​esponseFormat设置为XML JSON ：

  

确认该请求是一个POST请求，而不是GET。斯科特格思里有一个<一个href=\"http://weblogs.asp.net/scottgu/archive/2007/04/04/json-hijacking-and-how-asp-net-ajax-1-0-mitigates-these-attacks.aspx\">post解释为什么。

  
  

虽然它的jQuery编写的，这也可能对你有用：

I created an ASMX file with a code behind file. It's working fine, but it is outputting XML.

However, I need it to output JSON. The ResponseFormat configuration doesn't seem to work. My code-behind is:

[System.Web.Script.Services.ScriptService]
public class _default : System.Web.Services.WebService {
    [WebMethod]
    [ScriptMethod(UseHttpGet = true,ResponseFormat = ResponseFormat.Json)]
    public string[] UserDetails()
    {
        return new string[] { "abc", "def" };
    }
}

解决方案

From WebService returns XML even when ResponseFormat set to JSON:

Make sure that the request is a POST request, not a GET. Scott Guthrie has a post explaining why.

Though it's written specifically for jQuery, this may also be useful to you:
