node.js http get request parameters
提问by Alex Cebotari
I want to handle an HTTP request like this:
我想处理这样的 HTTP 请求:
GET http://1.2.3.4/status?userID=1234
But I can't extract the parameter userIDfrom it. I am using Express, but it's not helping me. For example, when I write something like the following, it doesn't work:
但我无法从中提取参数userID。我正在使用 Express,但它对我没有帮助。例如,当我编写如下内容时,它不起作用:
app.get('/status?userID=1234', function(req, res) {
// ...
})
I would like to have possibility to take value 1234for any local parameter, for example, user=userID. How can I do this?
我希望有可能1234为任何本地参数取值,例如,user=userID. 我怎样才能做到这一点?

You just parse the request URL with the native module.
您只需使用本机模块解析请求 URL。
var url = require('url');
app.get('/status', function(req, res) {
var parts = url.parse(req.url, true);
var query = parts.query;
})
You will get something like this:
你会得到这样的东西:
query: { userID: '1234' }
Edit:Since you're using Express, query strings are automatically parsed.
编辑:由于您使用的是 Express,查询字符串会自动解析。
req.query.userID
// returns 1234
