Node js http server accept POST and accept JSON

Question

I am trying to create one Node js server with http package. I want to receive only the POST request that I have already completed. The problem I am facing is that I cannot parse JSON correctly (I expect one JSON to be attached).

I tried using JSON.parse, but this does not parse all json content. It leaves some values ​​as [Object], which is incorrect. I saw several packages that are JSONStream, but I'm not sure how to implement in this case.

server.on('request', function(req, res){
    if(req.method == 'POST')
    {
        var jsonString;

        req.on('data', function (data) {
            jsonString = JSON.parse(data);
        });

        req.on('end', function () {
            serverNext(req, res, jsonString);
        });
    }
    else
    {
        res.writeHead(405, {'Content-type':'application/json'});
        res.write(JSON.stringify({error: "Method not allowed"}, 0, 4));
    }       
    res.end();
});

Request example:

Here d = the contents of the JSON file. (I did this in Python to make this sample request)

r = requests.post('http://localhost:9001', headers = {'content-type': 'application/json'}, data = json.dumps(d))

Note. I can parse JSON correctly, but there are times when it shows something like this:

{ 'Heading': 
   { 'Content': 
      { sometext: 'value',
        List: [Object],         // Wrong
        test: [Array] } } }     // Wrong

Update:

serverNext() , :

var testReq = Object.keys(jsonData)[0];
var testId = Object.keys(jsonData[testRequest])[0];
var test = jsonData[testRequest][testId]

, , - [Objects] .

Answer 1

"" data { "Foo": {"Bar": {"Some data": [43, 32, 44]} } } - : { Foo: { Bar: { 'Some data': [Object] } } }.

OP, JSON , , [Object] : JavaScript , String toString(), ( ) [Object] .

, JSON.stringify(). :

req.on('end', function () {
    serverNext(req, res, JSON.stringify(jsonString));
});

, jsonString jsonObject.
