Issue Description

Breaking change on v4.12.0:

The c.Bind is now mapping query params & request body to list of string.

Example:

POST /test?query=param

request body

{"field1": "somevalue"}

The code

request := make(map[string]interface{}) if err := c.Bind(&request); err != nil { return err } fmt.Printf("%#v", request)

Previous behaviour (pre v4.12.0):

Result: map[string]interface {}{"query":"param", "field1":"somevalue"}

Current behaviour (v4.12.0):

Result: map[string]interface {}{"query":[]string{"param"}, "field1":[]string{"somevalue"}}

Expected behaviour

The behaviour from the code above should keep on returning non-breaking change and still return this on the newest version:

Result: map[string]interface {}{"query":"param", "field1":"somevalue"}

Actual behaviour

In v4.12.0, the result from the code above returned different result:

Result: map[string]interface {}{"query":[]string{"param"}, "field1":[]string{"somevalue"}}

Steps to reproduce

Working code to debug

package main func main() { }
