1. field validate

   It provides a convenient method to verify the validity of the struct.

   type User struct {
      Name  string `validate:"min=4; max=16; noSpace"`
      Email string `validate:"email; noSpace"` 
   }
   
   user := User{
       ...
   }
   err := validate.Validate(&user)
   

   Built in tags:

   number
   eq	Equals
   gt	GreaterThan
   gte	GreaterThanOrEqual
   lt	LessThan
   lte	LessThanOrEqual
   ne	NotEqual

   String
   min	min length
   max	max length
   length	length
   noSpace	with no space

   other
   email	Email address format
   url	urladdress format

2. http client

   Based on net/http package, provide chain operation of HTTP request.

   	user := User{}
   	c := client.New("192.168.0.1:8080/api/v1/user")
   	err := c.AddHeader("Authorization", "Authorization token").
   		AddQuery("param1", "1").
   		AddQuery("param2", "2").
   		Get().
   		Do(&user)
   	if err != nil {
   		panic(err)
   	}
   
   
   // Prehandler: Server data preprocessing method
   type PreHandler interface {
   	PreHandler(body []byte) ([]byte, error)
   }
   
   type User struct {
   	Name string
   }
   
   type HttpResponse struct {
   	Code int
   	Msg  string
   	Data interface{}
   }
   
   func (r HttpResponse) PreHandler(body []byte) (data []byte,err error) {
   	...
   	return 
   }
   
   
   func main() {
   
   	user := User{}
   	c := client.New("192.168.0.1:8080/api/v1/user")
   	err := c.AddHeader("Authorization", "Authorization token").
   		AddQuery("param1", "1").
   		AddQuery("param2", "2").
   		Get().
   		AddPreHandler(&HttpResponse{}).
   		Do(&user)
   	if err != nil {
   		panic(err)
   	}
   }
