Express JS路由参数

Question

I need to use the data from quote_number parameter to create a query from this url:

http://localhost:3000/#/quote/line/?quote_number=1003

where quote_number = ${req.params.quote_number}

I'm expecting to get 1003 from this, but am getting line as the return parameter

Answer 1

The URL is not correct. Because you have the # symbol, Nothing is recognized after that. I don't know if you're doing it because there's no additional code.

If you try like this:

app.get('/quote/line/:id', (req, res) =>{
    console.log(req.params);
});

URL in browser:

http://localhost:3000/quote/line/quote_number=1003

result:

{ quote_number: 'quote_number=1003' }

if you use query instead of params :

app.get('/quote/line/', (req, res) =>{
    console.log(req.query);
});

in browser:

http://localhost:3000/quote/line/?quote_number=1003

result:

{ quote_number: '1003' }

and now, you can get the value by

req.query.quote_number
