编码转换获取响应 [英] Encoding conversion of a fetch response
本文介绍了编码转换获取响应的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
只要抓取完成,我正在尝试转换它到UTF-8。
这里的代码:
const iconv = require('iconv-lite');
fetch('http://www.band.uol.com.br/rss/colunista_64.xml',{
headers:{
Content-type: text / xml; charset = ISO-8859-1
}
})
.then(res => res.text()})
.then => {
const decodedText = iconv.decode(Buffer.from(text,'latin1'),'latin1')
,output = iconv.encode(decodedText,'utf8')
console.log(output.toString())
})
问题是:身体的所有特殊字符被¿½替换
对于转换,我使用的是 iconv-lite
这个问题的解决方法是什么?
解决方案>
最好的解决方法是使用 res.arrayBuffer()
而不是 res.text()
缓冲区构造函数接受 ArrayBuffer
代码:
取('http://www.band.uol.com.br/rss/colun ista_64.xml')
.then(res => res.arrayBuffer())
.then(arrayBuffer => iconv.decode(new Buffer(arrayBuffer),'iso-8859-1')。toString())
.then(converted => ; console.log(转换))
Inside a React Native method I'm fetching a xml encoded in ISO-8859-1.
As long as the fetching is completed I'm trying to convert it to UTF-8.
Here the code:
const iconv = require('iconv-lite');
fetch('http://www.band.uol.com.br/rss/colunista_64.xml', {
headers: {
"Content-type": "text/xml; charset=ISO-8859-1"
}
})
.then(res=>res.text()})
.then(text => {
const decodedText = iconv.decode(Buffer.from(text, 'latin1'), 'latin1')
, output = iconv.encode(decodedText, 'utf8')
console.log(output.toString())
})
The problem is: all especial characters of the body is being replaced by "¿½"
For the conversion, I'm using the package iconv-lite
What is the better workaround for this problem?
解决方案
The best workaround is to use res.arrayBuffer()
instead res.text()
, as long the Buffer constructor accepts ArrayBuffer
The code:
fetch('http://www.band.uol.com.br/rss/colunista_64.xml')
.then(res => res.arrayBuffer())
.then(arrayBuffer => iconv.decode(new Buffer(arrayBuffer), 'iso-8859-1').toString())
.then(converted => console.log(converted))
