Gorilla Mux Router GET URL with multiple query param only matches if called by all query params

Question

Below is a snapshot of a HTTP Get Call while using Gorilla Mux Router:

usersAPIs.HandleFunc("/users",
    middleware.WrapperHandler(th.List)).
    Queries("email", "{email}").
    Queries("order_by", "{order_by}").
    Queries("order_type", "{order_type}").
    Queries("page", "{page}").
    Queries("limit", "{limit}").
    Methods("GET")

Now when GET call happens with all query params e.g.

http://localhost:xxxx/accounts/users?email=a&page=1&limit=4&order_by=a&order_type=b 

then the gorilla mux router matches the pattern and takes it to the handler.

But when called like with fewer parameters e.g.

http://localhost:xxxx/accounts/users?email=a&page=1

then it says e.g. 404 not found means Resource path not mapped.

Questions :

#1. What has been missed here, is Go Gorilla Mux Router need all query params?

#2. What to be done If the GET query can come with zero or more parameters? e.g.

http://localhost:xxxx/accounts/users?email=a&page=1 

or

http://localhost:xxxx/accounts/users?page=1 

Answer 1

Queries(key, value) acts as a path matcher when passed to the route. Since 5 path params are expected, the route would match only if all 5 of them are present.

Though it's a little late to answer this question, but for anyone who stubles upon it later.
