JSON嵌套对象发布到node.js服务器? [英] JSON nested object post to node.js server?

问题描述

我想通过JSON将对象发布到node.js服务器.

I want to POST an Object via JSON to node.js server.

对象结构是嵌套的，从未成功在node.js服务器站点上正确接收和解析.

The Object structure is nested, and never succeeded to receive and parse correctly on node.js server site.

我找到了解决方案:请参阅答案部分...

我发现了

     console.log(body);

自身输出

val1 = hello& val2％5Bval3％5D = world

val1=hello&val2%5Bval3%5D=world

//= {"val1":你好"，"val2 [val3]":世界"}

//= {"val1":"hello","val2[val3]":"world"}

怪异的JSON方式

client.js

client.js

    var data ={val1:"hello",val2:{val3:"world"}};
    console.log(data); // -> *1
    $.ajax({
        url:"/",
        type:"POST",
        dataType: 'json',
        data:data,
        success:function (res)
        {
            resHandler(res);
        }
    });

对象

val1:你好"

val2:对象

val3:世界"

server.js

server.js

var onreq = function (req, res)
{
    if(req.method == 'POST')
    {
        var body = '';
        req.on('data', function (data)
        {
            body += data;
        });
        req.on('end', function ()
        {
            var json = qs.parse(body);
            console.log(json.val1); //hello
            console.log(json.val2); //undefined
            console.log(json.val3); //undefined

            console.log(JSON.stringify(json)); 
            //{"val1":"hello","val2[val3]":"world"}
        });
    }

我了解

I understand

val2 [val3] 是 val2.val3

val2[val3] is val2.val3

但是，

问题1

JSON.stringify打印出来

JSON.stringify prints out

{"val1":你好"，"val2 [val3]":世界"}

{"val1":"hello","val2[val3]":"world"}

不是

{val1:你好"，val2:{val3:世界"}}

{val1:"hello",val2:{val3:"world"}}

这很丑，我不知道为什么会这样.

It's ugly, and I don't know why it's like that.

问题2

我永远无法获得{val3:"world"}

I can never get {val3:"world"}

console.log(json.val3); //未定义

console.log(json.val3); //undefined

任何人都可以解释，如何将嵌套的JSON发布到node.js服务器?

Anyone can explain, and how can I POST a nested JSON to node.js server?

谢谢.

推荐答案

请勿在jQuery Ajax上使用JSON类型的数据，而应使用Stringified JSON

Do NOT use JSON typed data on jQuery Ajax, instead use Stringified JSON
