jQuery - How to PUT JSON via Ajax?
提问by Juri Glass
I am trying to put some JSON formatted data via Ajax with jQueryto a server. My code looks like this:
我试图通过带有jQuery 的Ajax 将一些 JSON 格式的数据放入服务器。我的代码如下所示：
$.ajax({
type: "PUT",
url: myURL,
contentType: "application/json",
data: {"data": "mydata"}
});
But on the server-side, I receive a data=mydatastring, instead of the expected JSON. Firebugtells me the same.
但是在服务器端，我收到一个data=mydata字符串，而不是预期的 JSON。Firebug告诉我同样的情况。
Where is the error?
错误在哪里？

I think the data needs to be a String. Objects are converted to query strings which is what you are seeing here.
我认为数据需要是一个字符串。对象被转换为查询字符串，这就是您在此处看到的内容。
You can use the JSON.stringify(obj)method to convert your Object to a String. The code for the JSON object is available from: https://github.com/douglascrockford/JSON-js/blob/master/json2.js.
您可以使用该JSON.stringify(obj)方法将对象转换为字符串。JSON 对象的代码可从：https: //github.com/douglascrockford/JSON-js/blob/master/json2.js 获得。
Alternately, just pass the code you are using to create the object as a literal String, but I imagine this is just an example and you'll want to encode some object you've already created.
或者，只需将用于创建对象的代码作为文字字符串传递，但我想这只是一个示例，您需要对已创建的对象进行编码。

If you always have to send JSON in your application, then you can just execute this somewhere in your init and then use default $.ajaxcall as in your example, and it will always serialize as a JSON string instead of the Ajax default query string.
如果你总是需要在你的应用程序中发送 JSON，那么你可以在你的 init 中的某个地方执行它，然后$.ajax像你的例子一样使用默认调用，它总是会序列化为 JSON 字符串而不是 Ajax 默认查询字符串。
Here I use the JSON object mentioned above:
这里我使用了上面提到的 JSON 对象：
$.ajaxSetup({
contentType : 'application/json',
processData : false
});
$.ajaxPrefilter( function( options, originalOptions, jqXHR ) {
if (options.data){
options.data=JSON.stringify(options.data);
}
});

//url: this is a reference to the XML, where you need to define the mapping.
//<entry key="/getEmpDetails/transEfileGenerate.app">
//<bean class="com.adp.ems.framework.spring.MappingItem" p:delegate-ref="efilePageDelegate"
//p:action="passJSONObjectAndGetWebServiceOutput" />
//str1 is the input JSON that you need to pass... Ajax will automatically take care to get the response.
//</entry>
var kw = {
url : "getEmpDetails/transEfileGenerate.app",
timeout : 30000,
handleAs : "json",
sync: false,
putData : str1,
headers: { "Content-Type": "application/json"},
load : function(result) {
},
