How to get raw http header string in node.js with express.js
提问by cschaeffler
I currently work with node.js and express.js. For my current project i need to access the raw strings of the HTTP headers (charset and accpeted).
我目前使用 node.js 和 express.js。对于我当前的项目，我需要访问 HTTP 标头（字符集和已接受）的原始字符串。
There is a function in express.js which returns those charsets and accepted headers, however, these are sorted by quality and therefore not useable for me in this special case i need.
express.js 中有一个函数可以返回这些字符集和接受的标头，但是，这些是按质量排序的，因此在我需要的这种特殊情况下对我来说不可用。
req.accepted // Returns sorted array of accepted header
req.acceptedCharsets // Returns sorted array of accepted lang header
However, I need the raw strings (iso-8859-5;q=.2, unicode-1-1;q=0.8, text/*;q=.5, application/json).
但是，我需要原始字符串（iso-8859-5；q=.2，unicode-1-1；q=0.8，text/*；q=.5，application/json）。
Now is there a way how i can access those raw strings in my express app?
现在有没有办法在我的 Express 应用程序中访问这些原始字符串？

req.headers
请求头文件
as in
如
var express = require('express');
var app = express.createServer();
app.get('/', function(req, res){
console.log(req.headers);
res.header('time', 12345);
res.send('Hello World');
});
app.listen(3000);
