注意：具体参数根据请求的不同而不同，请参考微信官方文档的参数说明！

参考文档：微信支付文档

获取微信用户OpenId、UnionId、SessionKey

userIdRsp, err := gopay.GetWeChatUserId(appID, secretKey, "")
if err != nil {
	fmt.Println("Error:", err)
	return
}
fmt.Println("OpenID:", userIdRsp.Openid)
fmt.Println("UnionID:", userIdRsp.Unionid)
fmt.Println("SessionKey:", userIdRsp.SessionKey)

微信小程序支付，需要进一步获取小程序支付所需要的参数

• 小程序支付所需要的参数，最好由后端计算后给出
  • timeStamp
  • nonceStr
  • package
  • signType
  • paySign

官方文档说明微信小程序支付API

timeStamp := strconv.FormatInt(time.Now().Unix(), 10)
packages := "prepay_id=" + wxRsp.PrepayId   //此处的 wxRsp.PrepayId ,统一下单成功后得到
paySign := gopay.GetMiniPaySign("wxd678efh567hg6787", wxRsp.NonceStr, packages, gopay.SignType_MD5, timeStamp, "192006250b4c09247ec02edce69f6a2d")

//微信小程序支付需要的参数信息
payRsp := new(vm.WeChatPayRsp)
fmt.Println("timeStamp：", timeStamp)
fmt.Println("nonceStr：", wxRsp.NonceStr)
fmt.Println("package：", packages)
fmt.Println("signType：", gopay.SignType_MD5)
fmt.Println("paySign：", paySign)

付款结果回调,需回复微信平台是否成功

代码中return写法，由于本人用的Echo Web框架，有兴趣的可以尝试一下

rsp := new(gopay.WeChatNotifyResponse) //回复微信的数据

rsp.ReturnCode = "SUCCESS"
rsp.ReturnMsg = "OK"

return c.String(http.StatusOK, rsp.ToXmlString())

统一下单

//初始化微信客户端
//    appId：应用ID
//    mchID：商户ID
//    secretKey：Key值
//    isProd：是否是正式环境
client := gopay.NewWeChatClient("wxd678efh567hg6787", "1230000109", "192006250b4c09247ec02edce69f6a2d", false)

//初始化参数Map
body := make(gopay.BodyMap)
body.Set("nonce_str", gopay.GetRandomString(32))
body.Set("body", "测试支付")
number := gopay.GetRandomString(32)
log.Println("Number:", number)
body.Set("out_trade_no", number)
body.Set("total_fee", 1)
body.Set("spbill_create_ip", "127.0.0.1")   //终端IP
body.Set("notify_url", "http://www.igoogle.ink")
body.Set("trade_type", gopay.TradeType_JsApi)

body.Set("openid", "o0Df70H2Q0fY8JXh1aFPIRyOBgu6")

//发起下单请求
wxRsp, err := client.UnifiedOrder(body)
if err != nil {
	fmt.Println("Error:", err)
	return
}
fmt.Println("ReturnCode：", wxRsp.ReturnCode)
fmt.Println("ReturnMsg：", wxRsp.ReturnMsg)
fmt.Println("Appid：", wxRsp.Appid)
fmt.Println("MchId：", wxRsp.MchId)
fmt.Println("DeviceInfo：", wxRsp.DeviceInfo)
fmt.Println("NonceStr：", wxRsp.NonceStr)
fmt.Println("Sign：", wxRsp.Sign)
fmt.Println("ResultCode：", wxRsp.ResultCode)
fmt.Println("ErrCode：", wxRsp.ErrCode)
