Functions

func QueryUser

func QueryUser(doer Doer) error

Types

type Doer

type Doer interface {
	Do(req *http.Request) (*http.Response, error)
}

We define a Doer interface, that has the method signature of the `http.Client` structs `Do` method

func NewHTTPClient

func NewHTTPClient() Doer

This gives us a regular HTTP client from the `net/http` package

func NewMockHTTPClient

func NewMockHTTPClient() Doer

This gives us a mock HTTP client, which returns an empty response for any request sent to it

type PersonA

type PersonA interface {
	Greet()
}

抽象工厂模式，它和简单工厂模式的唯一区别，就是它返回的是接口而不是结构体。 通过返回接口，可以在你不公开内部实现的情况下，让调用者使用你提供的各种功能。

func NewPerson

func NewPerson(name string, age int) PersonA
