NodeJS来自JSON调用的奇怪响应

Question

I got a strage response from my JSON call! This is my response output: Console Output

And that's my JSON request:

request({
url: url,
json: true
}, function (error, response, body) {
    if (!error && response.statusCode === 200) {
        console.log(body)
    }
})

I think it's something wrong about the charset, but i don't get how i can change this.

Solution:

// Had to decode url
var encoded = encodeURIComponent(name);
var url = "xxx" + encoded;

I've cleared a lot of misleading junk out of your code to get to the heart of the problem.

This now reproduces the original issue:

var request = require('request');

getItemPrice("StatTrak™ UMP-45 | Delusion (Minimal Wear)")

function getItemPrice(market_hash_name, callback) {
    var url = "http://steamcommunity.com/market/priceoverview/?currency=3&appid=730&market_hash_name=" + market_hash_name;

    request({
        url: url,
        json: true
    }, function(error, response, body) {
        console.log(body);
        if (!error && response.statusCode === 200) {
            console.log(parseFloat(((body.lowest_price).replace(/\,/g, '.')).split('&')[0]));
        }
    })
}

Your problem is that what you are calling is not a valid URL and the server is reacting to it badly.

You must encode special characters into the URL format:

var url = "http://steamcommunity.com/market/priceoverview/?currency=3&appid=730&market_hash_name=" + 
    encodeURIComponent(market_hash_name);

What kind of REST API do you call? If it's node js API, you can set the charset there

var req = http.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

And if that is not the case, set the request charset like this

request.setHeader('Accept-Charset', 'UTF-8)
