从StackOverflow API请求JSON的编码问题

Question

我无法想象我的生活.下面是请求模块的实现,但我也尝试使用node-XMLHttpRequest模块无济于事.

var request = require('request');

var url = 'http://api.stackexchange.com/2.1/questions?pagesize=100&fromdate=1356998400&todate=1359676800&order=desc&min=0&sort=votes&tagged=javascript&site=stackoverflow';

request.get({ url: url }, function(error, response, body) {
    if (error || response.statusCode !== 200) {
        console.log('There was a problem with the request');
        return;
    }

    console.log(body); // outputs gibberish characters like ?
    console.log(body.toString()); // also outputs gibberish
});

似乎是一个编码问题,但我在浏览器中使用了完全相同的代码(使用本机XHR对象),它没有问题.我究竟做错了什么？

Answer 1

内容被gzip压缩.您可以使用request,并zlib解压缩从API流式的回应:

var request = require('request')
   ,zlib = require('zlib');

var url = 'http://api.stackexchange.com/2.1/questions?pagesize=100&fromdate=1356998400&todate=1359676800&order=desc&min=0&sort=votes&tagged=javascript&site=stackoverflow';

request({ url: url, headers: {'accept-encoding': 'gzip'}})
  .pipe(zlib.createGunzip())
  .pipe(process.stdout);  // not gibberish

(参考:https: //stackoverflow.com/a/14739453/112196)

Answer 2

虽然pero的答案是正确的,但有一种更简单的方法可以做到这一点.

由于您正在使用请求,您还可以添加gzip: true标记:

var request = require('request');

var url = 'http://api.stackexchange.com/2.1/questions?pagesize=100&fromdate=1356998400&todate=1359676800&order=desc&min=0&sort=votes&tagged=javascript&site=stackoverflow';

request.get({ url: url, headers: {'accept-encoding': 'gzip'}, gzip: true }, function(error, response, body) {
    console.log(body); // not gibberish
});
