Question

我正在尝试获取CSS样式表，由于某种原因，响应都是乱码。这是编码错误吗？响应头表示编码只是UTF-8。

var https = require('https');
var fs = require('fs');

var url ='https://d14pr3cu5atb0x.cloudfront.net/pkg/css/chimera-e6f0150f64.css';

var request = https.request(url, function (res) {
    var data = '';
    res.on('data', function (chunk) {
        data += chunk;
    });
    res.on('end', function () {
        console.log(data);
    });
});
request.on('error', function (e) {
    console.log(e.message);
});
request.end();

输出：

我从未使用过node.js，但对我而言，看起来数据是压缩的，并且基于此处的文档：https://www.npmjs.com/package/request看起来您需要启用gzip才能获得正确的响应。下面是文档设置gzip中示例的复制和粘贴，它会生成正确的数据：

var url ='https://d14pr3cu5atb0x.cloudfront.net/pkg/css/chimera-e6f0150f64.css';
var request = require('request')
  request(
    { method: 'GET'
    , uri: url
    , gzip: true
    }
  , function (error, response, body) {
      // body is the decompressed response body
      console.log('server encoded the data as: ' + (response.headers['content-encoding'] || 'identity'))
      console.log('the decoded data is: ' + body)
    }
  )
  .on('data', function(data) {
    // decompressed data as it is received
    console.log('decoded chunk: ' + data)
  })
  .on('response', function(response) {
    // unmodified http.IncomingMessage object
    response.on('data', function(data) {
      // compressed data as it is received
      console.log('received ' + data.length + ' bytes of compressed data')
    })
  })

https请求响应css文本是乱码
