req.param()
Returns the value of the parameter with the specified name.
Usage
req.param(name);
Details
req.param()
searches the url path, query string, and body of the request for the specified parameter. If no parameter value exists anywhere in the request with the given name
, it returns undefined
.
- url path parameters (
req.params
)- e.g. a request "/foo/4" to route
/foo/:id
has url path params{ id: 4 }
- e.g. a request "/foo/4" to route
- query string parameters (
req.query
)- e.g. a request "/foo?email=5" has query params
{ email: 5 }
- e.g. a request "/foo?email=5" has query params
- body parameters (
req.body
)- e.g. a request with a parseable body (e.g. JSON, url-encoded, or XML) has body parameters equal to its parsed value
Example
Consider a route (POST /product/:sku
) which points to a blueprint, controller, or policy with the following code:
req.param('sku');
// -> 123
We can get the expected result by sending the sku
parameter any of the following ways:
POST /product/123
POST /product?sku=123
POST /product
- with a JSON request body:
{ "sku": 123 }
- with a JSON request body:
Notes
- If you'd like to get ALL parameters from ALL sources (including the URL path, query string, and parsed request body) you can use
req.allParams()
.
