您好我已经实现了一个 Ajax POST 请求来调用 Web 服务。它总是返回 200 OK 但执行失败的事件我已经尝试了很多事情，但我没有得到我做错的地方。我在这里添加我的代码。Fiddler显示响应内容，但 Ajax 未执行成功事件。

<!DOCTYPE html>
<html><head>
<script src="http://code.jquery.com/jquery-1.7.1.min.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">

$.ajax({
    type: "POST",
    url: url,
    data: values,
    dataType: 'json',
    cache: false,
    success: function (result) {
        alert("success:"+result);
    },
    error:function (error) {
        alert("error"+error);
    }
});
</script>
</body>
</html>

我试过 dataType:'text'....来自服务器的响应是正确的 JSON 格式

请求 JSON 数据：

{
    "search": {
        "params_attributes": {
            "adults": "1",
            "children": "0",
            "depart_date": "2013-07-10",
            "destination_name": "OMS",
            "direct": "0",
            "infants": "0",
            "origin_name": "KUL",
            "range": "0",
            "trip_class": "0"
        }
    },
    "signature": "XXXXXXXX",
    "marker": "XXX"
}

响应 JSON 数据：

    "search_id":"66",
    "metadata" : {},
    "tickets" : [
        {
            "native_prices":{"7":"5500.0", "6":"5680.0", "3":"5657.0"},

在没有看到 JSON 响应的情况下，我不得不猜测，问题在于，您使用的是错误的（或没有）JSON 引号。您必须使用双引号（用于属性名称和字符串值），或者至少当我遇到这个问题时，双引号解决了它。

例子：

{"id":1,"name":"TOM"}

我希望这有帮助。

对于其他有此类错误的朋友，请尝试将 JSON 值返回到您发送值的页面。

就我而言，我在localhost:8080/sender将 JSON 数据发送到localhost:8110/receiver页面的页面上。接收者页面获取数据后，返回类似{}返回到发送者页面的内容。否则，即使服务器返回 200 HTTP 代码，也会调用错误回调。
