快递路线从哪里开始？

Question

I'm trying to create a route that begins with a question mark and I cannot get it done. This is what I have:

app.get('/?email=:e', function(req, res){
    console.log("here");
    console.log(req.body);
});

I'm trying to have the user enter something that will be 'e' and the route be '/?email='.

Am I dong it correctly? Is there something I am missing?

Answer 1

well api routing doesn't allow ? in the url, because it would automatically be resolved as a query parameter.

Answer 2

If you are trying something like http://localhost:3000/?email=abc@example.com then the function should be

app.get('/', function(req, res){
    console.log("email is " + req.query.email);
});

If you want to send email in your path something like http://localhost:3000/email/abc@example.com then you may try

app.get('/email/:email', function(req, res){
    console.log("email is " + req.params.email);
});

or email path with e query string something like http://localhost:3000/email?e=abc@example.com

app.get('/email', function(req, res){
    console.log("email is " + req.query.e);
});
