nodejs使用请求编码

Question

我试图通过请求获得正确的编码.

request.get({
    "uri":'http://www.bold.dk/tv/',
    "encoding": "text/html;charset='charset=utf-8'"
  },
  function(err, resp, body){    
    console.log(body);
  }
);

无论我做什么,丹麦字符的编码都是不对的.

有什么想法吗？

Answer 1

您可以使用iconv(lite)来转换它.您还需要通过将encoding属性设置为null来告诉请求不要将编码设置为默认的UTF-8.因此你应该这样做:

var iconv = require('iconv-lite');
request.get({
    uri:'http://www.bold.dk/tv/',
    encoding: null
  },
  function(err, resp, body){    
    var bodyWithCorrectEncoding = iconv.decode(body, 'iso-8859-1');
    console.log(bodyWithCorrectEncoding);
  }
);

Answer 2

也许你的问题出在'Accept-Encoding'标题上。假设你有像这样的标题'Accept-Encoding': 'gzip,deflate'

如果是这样，您有两种方法可以解决此问题：

1. 删除此标头

2. 使用以下代码解压数据：

   const req = request(options, res => {
       let buffers = []
       let bufferLength = 0
       let strings = []
   
       const getData = chunk => {
           if (!Buffer.isBuffer(chunk)) {
               strings.push(chunk)
           } else if (chunk.length) {
               bufferLength += chunk.length
               buffers.push(chunk)
           }
       }
   
       const endData = () => {
           let response = {code: 200, body: ''}
           if (bufferLength) {
               response.body = Buffer.concat(buffers, bufferLength)
               if (options.encoding !== null) {
                   response.body = response.body.toString(options.encoding)
               }
               buffers = []
               bufferLength = 0
           } else if (strings.length) {
               if (options.encoding === 'utf8' && strings[0].length > 0 && strings[0][0] === '\uFEFF') {
                   strings[0] = strings[0].substring(1)
               }
               response.body = strings.join('')
           }
           console.log('response', response)
       };
   
       switch (res.headers['content-encoding']) {
           // or, just use zlib.createUnzip() to handle both cases
           case 'gzip':
               res.pipe(zlib.createGunzip())
                   .on('data', getData)
                   .on('end', endData)
               break;
           case 'deflate':
               res.pipe(zlib.createInflate())
                   .on('data', getData)
                   .on('end', endData)
               break;
           default:
               res.pipe(zlib.createInflate())
                   .on('data', getData)
                   .on('end', endData)
               break;
       }
   });
