I am trying to retrieve values sent to the server:
"/stuff?a=a&b=b&c=c"
Can you please advise me on how to extract these values using express?
So far, I have attempted...
app.get( "/stuff?:a&:b&:c", function( req, res ){});
...but unfortunately, it seems that the route is not being recognized.
Thank you in advance for any assistance you can provide.
Avoid incorporating a query string directly into a route for better practice.
When using Express, it's recommended to create a specific route for "/stuff". Any query strings can then be accessed through req.query.
If you want to define your route directly using /items, then you can easily access query parameters through the req.query object, which is a JSON structure.
Here's an example for better understanding:
app.get("/items", function(req, res) {
var item = req.query.item;
...
});
In this scenario, the values in req.query would be:
{ item: 'item1',
quantity: '2',
price: '15' }
You can also refer to Express documentation (for versions 4.x and 3.x) for more examples: Express - req.query.
