NodeJS Express encodes the URL - how to decode
提问by AlexD
I'm using NodeJS with Express, and when I use foreign characters in the URL, they automatically get encoded.
我在 Express 中使用 NodeJS，当我在 URL 中使用外来字符时，它们会自动进行编码。
How do I decode it back to the original string?
如何将其解码回原始字符串？
Before calling NodeJS, I escape characters.
在调用 NodeJS 之前，我会转义字符。
So the string: ?????
所以字符串： ?????
Becomes %u05D0%u05D5%u05D1%u05DE%u05D4
成为 %u05D0%u05D5%u05D1%u05DE%u05D4
The entire URL now looks like: http://localhost:32323/?query=%u05D0%u05D5%u05D1%u05DE%u05D4
整个 URL 现在看起来像： http://localhost:32323/?query=%u05D0%u05D5%u05D1%u05DE%u05D4
Now in my NodeJS, I get the escaped string %u05D0%u05D5%u05D1%u05DE%u05D4.
现在在我的 NodeJS 中，我得到了转义字符串%u05D0%u05D5%u05D1%u05DE%u05D4。
This is the relevant code:
这是相关代码：
var url_parts = url.parse(req.url, true);
var params = url_parts.query;
var query = params.query; // '%u05D0%u05D5%u05D1%u05DE%u05D4'
I've tried urland querystringlibraries but nothing seems to fit my case.
我试过url和querystring图书馆，但似乎没有什么适合我的情况。
querystring.unescape(query); // still '%u05D0%u05D5%u05D1%u05DE%u05D4'

escapeand unescapeare deprecated.
escape并unescape已弃用。
Use:encodeURIComponent('?????') // %D7%90%D7%95%D7%91%D7%9E%D7%94decodeURIComponent('%D7%90%D7%95%D7%91%D7%9E%D7%94') // ?????
用：encodeURIComponent('?????') // %D7%90%D7%95%D7%91%D7%9E%D7%94decodeURIComponent('%D7%90%D7%95%D7%91%D7%9E%D7%94') // ?????
Old answer
旧答案
unescape('%u05D0%u05D5%u05D1%u05DE%u05D4')gives "?????"
unescape('%u05D0%u05D5%u05D1%u05DE%u05D4')给 "?????"
Try:
尝试：
var querystring = unescape(query);
var querystring = unescape(query);

You should use decodeURI()and encodeURI()to encode/decode a URL with foreign characters.
您应该使用decodeURI()和encodeURI()对带有外来字符的 URL 进行编码/解码。
Usage:
用法：
var query = 'http://google.com';
query = encodeURI(query);
query = decodeURI(query); // http://google.com
