jQuery 不会从 AJAX 查询中解析我的 JSON

我在使用 jQuery.ajax() 解析从我的服务器返回的一些 JSON 数据时遇到困难

I'm having difficulty parsing some JSON data returned from my server using jQuery.ajax()

要执行我正在使用的 AJAX:

To perform the AJAX I'm using:

$.ajax({
  url: myUrl,
  cache: false,
  dataType: "json",
  success: function(data){
    ...
  },
  error: function(e, xhr){
    ...
  }
});

如果我返回一个项目数组，那么它工作正常:

And if I return an array of items then it works fine:

[ { title: "One", key: "1" }, { title: "Two", key: "2" } ]

调用成功函数并接收正确的对象.

The success function is called and receives the correct object.

但是，当我尝试返回单个对象时:

However, when I'm trying to return a single object:

{ title: "One", key: "1" }

错误函数被调用并且 xhr 包含parsererror".在将它发送到网络之前，我已经尝试将 JSON 包装在服务器上的括号中，但这没有任何区别.然而，如果我将内容粘贴到 Javascript 中的字符串中，然后使用 eval() 函数，它会完美地评估它.

The error function is called and xhr contains 'parsererror'. I've tried wrapping the JSON in parenthesis on the server before sending it down the wire, but it makes no difference. Yet if I paste the content into a string in Javascript and then use the eval() function, it evaluates it perfectly.

任何想法我做错了什么?

Any ideas what I'm doing wrong?

推荐答案

您的服务器是否以 Content-Type "*/json" 形式发送数据?如果不是，请相应地修改响应标头.例如，发送 "application/json" 就可以了.

Is your server sending data as Content-Type "*/json"? If not, modify the response headers accordingly. Sending "application/json" would be fine, for example.
