jQuery 在请求正文中发布有效的 json

本文介绍了jQuery 在请求正文中发布有效的 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

所以根据jQuery Ajax docs，它以查询的形式序列化数据发送请求时的字符串，但设置 processData:false 应该允许我在正文中发送实际的 JSON.不幸的是，我很难首先确定是否发生了这种情况，其次是将对象发送到服务器的样子.我只知道服务器没有解析我发送的内容.

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.

当使用 http 客户端 发布对象文字 {someKey:'someData'}，它的工作原理.但是当使用带有 data: {someKey:'someData'} 的 jQuery 时，它会失败.不幸的是，当我在 Safari 中分析请求时，它说消息有效负载是 [object Object] ... 太好了......而在 Firefox 中，帖子是空白的......

When using http client to post an object literal {someKey:'someData'}, it works. But when 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...

当在 Java 端记录正文内容时，它实际上得到 [object Object] 那么如何发送真正的 JSON 数据??

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

有没有人使用 Java 服务序列化请求正文中的 JSON 数据，请求从 jQuery 发送?

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

顺便说一句，这里是完整的 $.ajax 请求:

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' });

推荐答案

实际的 JSON 请求如下所示:

An actual JSON request would look like this:

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

您发送实际 JSON 字符串的位置.如需更通用的解决方案，请使用 JSON.stringify()将对象序列化为 JSON，如下所示:

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" }),

要支持没有 JSON 对象的旧浏览器，请使用 json2.js 将其添加进来.

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

当前发生的事情是因为你有 processData: false，它基本上发送了这个:({"command":"on"}).toString() 这是[object Object]...您在请求中看到的内容.

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.
