Node.js Express req.query未定義
[英]Node.js Express req.query is undefined
I'm running the following code on Node.js with Express 4.7.2
我正在使用Express 4.7.2在Node.js上運行以下代碼
express.get('/test1',function(req, res) {
var ttt = false;
if (req.query.username === undefined) ttt = true;
res.json({query: ttt});
});
I call the URL:
我稱之為URL：
{{protocol}}://{{server}}/test1?username=1
{{協議}}：// {{服務器}} / TEST1用戶名= 1
And I get the result:
我得到了結果：
{query: true}
{query：true}
Which shows req.query.username is indeed undefined
這表明req.query.username確實是未定義的
What am I missing? How come the query param is not passed in?
我錯過了什么？怎么沒有傳入查詢參數？

The code you've shown works fine for me with node v0.10.30 and express 4.8.7:
您顯示的代碼適用於節點v0.10.30並表達4.8.7：
var app = require('express')();
app.get('/test1',function(req, res) {
var ttt = false;
if (req.query.username === undefined) ttt = true;
res.json({query: ttt});
});
app.listen(8000);
I then navigate to http://localhost:8000/test1?username=1 and it displays {"query":false}.
然后我導航到http：// localhost：8000 / test1？username = 1並顯示{“query”：false}。
