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.Code2Session(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，统一下单后，需要进一步获取微信小程序支付所需要的paySign

• 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
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，统一下单后，需要进一步获取H5支付所需要的paySign

• 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 ```go 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, "192006250b")

//微信内H5支付需要的参数信息 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)

### APP支付，统一下单后，需要进一步获取APP支付所需要的paySign

* APP支付所需要的参数，paySign由后端计算
    * appid
    * partnerid
    * noncestr
    * prepayid
    * package 
    * timestamp
    * sign
> 官方文档说明[APP端调起支付的参数列表文档](https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=9_12)
```go
timeStamp := strconv.FormatInt(time.Now().Unix(), 10)
//注意：signType：此处签名方式，务必与统一下单时用的签名方式一致
//注意：package：参数因为是固定值，不需开发者再传入
sign := gopay.GetH5PaySign(appid, partnerid, wxRsp.NonceStr, prepayid, gopay.SignType_MD5, timeStamp, apiKey)

//APP支付需要的参数信息
fmt.Println("sign：", sign)

支付结果通知回调：参数解析和Sign值的验证

微信支付后的回调通知文档支付结果通知

//解析支付完成后的回调信息
notifyRsp, err := gopay.ParseNotifyResult(c.Request())
if err != nil {
    fmt.Println("err:", err)
}
fmt.Println("notifyRsp:", notifyRsp)

//支付通知的签名验证和参数签名后的Sign
//    apiKey：API秘钥值
//    signType：签名类型 MD5 或 HMAC-SHA256（默认请填写 MD5）
//    notifyRsp：利用 gopay.ParseNotifyResult() 得到的结构体
//    返回参数ok：是否验证通过
//    返回参数sign：根据参数计算的sign值，非微信返回参数中的Sign
ok, sign := gopay.VerifyPayResultSign("192006250b4c09247ec02edce69f6a2d", "MD5", notifyRsp)
log.Println("ok:", ok)
log.Println("sign:", sign)

加密数据，解密到指定结构体

data := "Kf3TdPbzEmhWMuPKtlKxIWDkijhn402w1bxoHL4kLdcKr6jT1jNcIhvDJfjXmJcgDWLjmBiIGJ5acUuSvxLws3WgAkERmtTuiCG10CKLsJiR+AXVk7B2TUQzsq88YVilDz/YAN3647REE7glGmeBPfvUmdbfDzhL9BzvEiuRhABuCYyTMz4iaM8hFjbLB1caaeoOlykYAFMWC5pZi9P8uw=="
iv := "Cds8j3VYoGvnTp1BrjXdJg=="
sessionKey := "lyY4HPQbaOYzZdG+JcYK9w=="

phone := new(gopay.WeChatUserPhone)
err := gopay.DecryptOpenDataToStruct(data, iv, sessionKey, phone)
if err != nil {
	fmt.Println("err:", err)
	return
}
fmt.Println("PhoneNumber:", phone.PhoneNumber)
fmt.Println("PurePhoneNumber:", phone.PurePhoneNumber)
fmt.Println("CountryCode:", phone.CountryCode)
fmt.Println("Watermark:", phone.Watermark)

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())
