jQuery的张贴在请求主体有效的JSON

本文介绍了jQuery的张贴在请求主体有效的JSON的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

因此​​根据 jQuery的Ajax的文档,它发送请求时串行数据在查询字符串的形式,但设置过程数据:假应该让我的身体发出的实际JSON。不幸的是,我有一个很难确定的第一,如果发生这种情况,并第二次是什么物体看起来像正在被发送到服务器。我所知道的是,服务器并不解析什么我发送。

使用 HTTP客户端发布对象文本时 {someKey:someData'} 它的工作原理。但使用jQuery与数据:{someKey:someData'} 失败。不幸的是,当我分析了Safari浏览器的请求时,它表示该消息负载是 [对象的对象] ...伟大的...而在Firefox后是空白...

在登录的主体内容在Java端,它确实获得 [对象的对象] 那么,如何发送实时JSON数据??

有没有人有一个Java服务序列化JSON数据请求体,与jQuery的发送请求的经验?

BTW这里是全$就要求:

  $。阿贾克斯({
    的contentType:应用/ JSON的,
    数据: {
        命令:上
    },
    数据类型:JSON,
    成功:功能(数据){
        app.log(设备控制成功);
    },
    错误:函数(){
        app.log(设备控制失败);
    },
    过程数据:假的,
    键入:POST,
    网址:'/设备/ {DEVICE_ID} /控制
});
 

解决方案

这是实际的JSON请求是这样的:

 数据:{命令:关于}
 

如果你发送一个实际的JSON字符串。对于更广泛的解决方案,使用<$c$c>JSON.stringify()序列化对象到JSON,像这样的:

 数据:JSON.stringify({命令:关于}),
 

要支持不具备 JSON 对象旧的浏览器,使用 json2.js 将在添加。


什么是目前发生的事情是,因为你有过程数据:假,它基本上发送此:({命令:关于})。的toString() [对象的对象] ...你在你的请求看到的。

So according to the jQuery Ajax docs, it serializes data in the form of a query string when sending requests, but setting processData:false should allow me to send actual JSON in the body. Unfortunately I'm having a hard time determining first, if this is happening and 2nd what the object looks like that is being sent to the server. All I know is that the server is not parsing what I'm sending.

Using http client when posting an object literal {someKey:'someData'} it works. but using jQuery with data: {someKey:'someData'} it fails. Unfortunately when i analyze the request in safari, it says the message payload is [object Object] ... great... and in Firefox the post is blank...

When logging the body content on the java side it literally gets [object Object] so how does one send REAL json data??

Has anyone had experience with a Java service serializing json data in the request body, with the request sent from jQuery?

BTW here is the full $.ajax request:

$.ajax({
    contentType: 'application/json',
    data: {
        "command": "on"
    },
    dataType: 'json',
    success: function(data){
        app.log("device control succeeded");
    },
    error: function(){
        app.log("Device control failed");
    },
    processData: false,
    type: 'POST',
    url: '/devices/{device_id}/control'
});
解决方案

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.


What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.
