微信支付

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，需要进一步获取微信小程序支付所需要的参数
  • 小程序支付所需要的参数，paySign由后端计算
    • 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)
微信内H5支付，同样需要进一步获取支付所需要的参数（与微信小程序支付类似）
  • 微信内H5支付所需要的参数，paySign由后端计算
    • appId
    • timeStamp
    • nonceStr
    • package
    • signType
    • paySign

官方文档说明微信内H5支付文档

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.GetH5PaySign("wxd678efh567hg6787", wxRsp.NonceStr, packages, gopay.SignType_MD5, timeStamp, "192006250b4c09247ec02edce69f6a2d")

//微信内H5支付需要的参数信息
payRsp := new(vm.WeChatPayRsp)
fmt.Println("appId:","wxd678efh567hg6787")
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
