[Context API Request] Add ReadQuery for convenient obtain query struct.

[zheeeng]

example code:

type Query structure {
    Foo *string `url:"foo"`
    Bar *int `url:"bar"`
}

// in handler, assume the path is: api.example.com/path?foo=hello&bar=42

func (c iris.Context) {
    q := Query{}
    err := c.ReadQuery(&Query) 
    fmt.Println(c.foo == "hello")  // true
    fmt.Println(c.bar == 42)  // true
}

This would be nice if it also support multiple same key values like ?a=car&a=motorcycle

Yeah, it should depend on that is the structure with 'a' is slice type or not.

Hello @zheeeng and @Dexus did you try the ReadForm? if it is a get request it should be reading from queries.

Seems that we can't rule the case conversion by tags? I tried github.com/gorilla/schema and it satisfies my demands.

Done @zheeeng and @Dexus on 11.2.1 as you exactly requested:

ReadQuery // with "url" tag name, strictly as you requested.
ReadForm // stays with "form" tag name, strictly.
