请求参数

  • 支付内部调用参数传递类型Params util.Params
  • appid mch_id nonce_str sign sign_type 内部会自动传入
  • spbill_create_ip 如果外部传入参数没有，后续调用会自动获取
  • sign_type 外部不传入，默认MD5
import "github.com/fideism/golang-wechat/util"

// Params map[string]interface{}
type Params map[string]interface{}

// Set 设置值
func (p Params) Set(k string, v interface{})

// Get 获取值
func (p Params) Get(k string) (v interface{})

// GetString 强制获取k对应的v string类型
func (p Params) GetString(k string) string

// Exists 判断是否存在
func (p Params) Exists(k string) bool

//具体使用
p := util.Params{
		"openid":       "xx",
}

//alse can
p.Set("notify_url", "https://github.com/fideism/golang-wechat")
