Node.js-使用querystring以GET/POST的形式发送和接收数组

问题描述

我有以下代码，但似乎不起作用:

var post_req = {
    array: [
        [ {
            param1: 'something',
            param2: 123
        } ],
        [ ],
        [ ],
        [ {
            param2: 'something',
            param4: 1234,
            param1: 'hello'
        } ]
    ]
};
var data_send = querystring.stringify(post_req);

var request = client.request('POST', '/', headers);
request.end(data_send);

和

if( req.method == 'POST' ) {
    req.addListener('data', function(chunk)
    {
        POST = querystring.parse(chunk);
        console.log(POST);
    }
}

我最终得到了5个子数组，它们对应于对象中的5个参数，但它们的名称中带有额外的'] ['字符:

{ array:
   [ { '][param1': 'something' }
   , { '][param2': '123' }
   , { '][param2': 'something' }
   , { '][param4': '1234' }
   , { '][param1': 'hello' }
   ]
}

解决方案

有一个解决此问题的新节点程序包:"npm install qs".

https://github.com/ljharb/qs

用于支持嵌套的节点的查询字符串解析器，因为它已从0.3.x中删除，因此该库提供了以前的且通常需要的行为(并且速度是以前的两倍)"

如果任何人都可以告诉我为什么将其从0.3.x中删除，我将给您投票赞成您的评论. (我希望恢复对Node.js的信心.)

I've got the following code, but it doesn't seem to work:

var post_req = {
    array: [
        [ {
            param1: 'something',
            param2: 123
        } ],
        [ ],
        [ ],
        [ {
            param2: 'something',
            param4: 1234,
            param1: 'hello'
        } ]
    ]
};
var data_send = querystring.stringify(post_req);

var request = client.request('POST', '/', headers);
request.end(data_send);

and

if( req.method == 'POST' ) {
    req.addListener('data', function(chunk)
    {
        POST = querystring.parse(chunk);
        console.log(POST);
    }
}

I end up with 5 sub-arrays, corresponding to the 5 parameters in the objects but with extra '][' characters in their names:

{ array:
   [ { '][param1': 'something' }
   , { '][param2': '123' }
   , { '][param2': 'something' }
   , { '][param4': '1234' }
   , { '][param1': 'hello' }
   ]
}

解决方案

There is a new node package that fixes this: "npm install qs".

https://github.com/ljharb/qs

"query string parser for node supporting nesting, as it was removed from 0.3.x, so this library provides the previous and commonly desired behaviour (and twice as fast)"

If anyone can tell me why it was removed from 0.3.x, I will give you an upvote for your comment. (I want my confidence in Node.js restored.)
