/search?name=:name

but this works : 但这有效：

/search/name=:name

how to make the former work with the ? 如何使前者与之配合使用? (Question mark) （问号）

Answer 1

Query strings are not part of the route path. 查询字符串不是路由路径的一部分。

If you want to use the query string, use req.query : 如果要使用查询字符串，请使用req.query ：

app.get('/search', function (req, res) {
  console.log(req.query);
});

Answer 2

What you want is either route parameters: 您想要的是两个路由参数：

app.get('/foo/:bar', (req, res) => { //GET /foo/helloworld
    console.log(req.params.bar);     //helloworld
    //...
});

Or GET parameters: 或GET参数：

app.get('/foo', (req, res) => {  //GET /foo?bar=helloworld
    console.log(req.query.bar);  //helloworld
    //...
});

What you are doing right now is mixing them up, which doesn't work. 您现在正在做的是将它们混合在一起，这是行不通的。
