Types

type CipherSuite

type CipherSuite struct {
	// contains filtered or unexported fields
}

CipherSuite 算法套件，包括验签和解密

type ContentMap

type ContentMap map[string]interface{}

ContentMap 将微信支付通知请求内容Json解密后的内容Map

type EncryptedResource

type EncryptedResource struct {
	Algorithm      string `json:"algorithm"`
	Ciphertext     string `json:"ciphertext"`
	AssociatedData string `json:"associated_data"`
	Nonce          string `json:"nonce"`
	OriginalType   string `json:"original_type"`

	Plaintext string // Ciphertext 解密后内容
}

EncryptedResource 微信支付通知请求中的内容

type Handler

type Handler struct {
	// contains filtered or unexported fields
}

Handler 通知处理器，使用前先设置验签和解密的算法套件

func NewEmptyHandler

func NewEmptyHandler() *Handler

NewEmptyHandler 创建一个不包含算法套件的空通知处理器

func NewNotifyHandler

func NewNotifyHandler(apiV3Key string, verifier auth.Verifier) *Handler

NewNotifyHandler 创建通知处理器 Deprecated: Use NewRSANotifyHandler instead

func NewRSANotifyHandler

func NewRSANotifyHandler(apiV3Key string, verifier auth.Verifier) (*Handler, error)

NewRSANotifyHandler 创建一个 RSA 的通知处理器，它包含 AES-GCM 解密能力

func (*Handler) AddCipherSuite

func (h *Handler) AddCipherSuite(cipherSuite CipherSuite) *Handler

AddCipherSuite 添加一个算法套件

func (*Handler) AddRSAWithAESGCM

func (h *Handler) AddRSAWithAESGCM(verifier auth.Verifier, aesgcm cipher.AEAD) *Handler

AddRSAWithAESGCM 添加一个 RSA + AES-GCM 的算法套件

func (*Handler) ParseNotifyRequest

func (h *Handler) ParseNotifyRequest(
	ctx context.Context,
	request *http.Request,
	content interface{},
) (*Request, error)

ParseNotifyRequest 从 HTTP 请求(http.Request) 中解析 微信支付通知(notify.Request)

Example (No_model)

package main

import (
	"context"
	"fmt"
	"net/http"

	"github.com/charleybin/wechatpay-go/core/notify"
)

func main() {
	var handler notify.Handler
	var request *http.Request

	content := make(map[string]interface{})
	notifyReq, err := handler.ParseNotifyRequest(context.Background(), request, content)
	if err != nil {
		fmt.Println(err)
		return
	}

	// 处理通知内容
	fmt.Println(notifyReq.Summary)
	fmt.Println(content)
}

Example (Transaction)

package main

import (
	"context"
	"fmt"
	"net/http"

	"github.com/charleybin/wechatpay-go/core/notify"
	"github.com/charleybin/wechatpay-go/services/payments"
)

func main() {
	var handler notify.Handler
	var request *http.Request

	content := new(payments.Transaction)
	notifyReq, err := handler.ParseNotifyRequest(context.Background(), request, content)
	if err != nil {
		fmt.Println(err)
		return
	}

	// 处理通知内容
	fmt.Println(notifyReq.Summary)
	fmt.Println(content)
}

type Request

type Request struct {
	ID           string             `json:"id"`
	CreateTime   *time.Time         `json:"create_time"`
	EventType    string             `json:"event_type"`
	ResourceType string             `json:"resource_type"`
	Resource     *EncryptedResource `json:"resource"`
	Summary      string             `json:"summary"`

	// 原始通知请求
	RawRequest *http.Request
}
