Concrete problem solved: WeChat API work requires many endpoint calls plus AES encryption, decryption, signature, verification, callback notification encryption, token refresh. PowerWeChat wraps lower steps. Users focus on API usage, not each WeChat security detail. README says goal reduce difficulty, install once, cover WeChat function interfaces. It says most interfaces support strong typing. It says complete test project supports Web API testing.

Key capabilities

• Covers mini program APIs, including auth login session code to OpenID.
• Covers official account APIs: server, messages, broadcast, user, user tags, OAuth, JSSDK, QR code, short key, media, material, menu, card, customer service, shake around, data cube, reply, comment, goods.
• Covers WeCom APIs.
• Covers WeChat Pay APIs.
• Covers open platform APIs.
• Handles AES encryption, decryption, signature, verification, callback notification encryption.
• Provides typed interfaces, tests, Web API test project, docs, tutorials, video tutorials.

Who uses it and how

• Go backend teams add mini program login. They create miniProgram.NewMiniProgram with AppID, Secret, HttpDebug, Debug from environment variables, then call app.Auth.Session(code) to get OpenID.
• Official account teams handle server callbacks, messages, broadcast, user tags, OAuth, JSSDK, QR code, media, menu, customer service.
• Payment teams integrate WeChat Pay API endpoints through SDK wrappers.
• WeCom teams call enterprise WeChat APIs through SDK wrappers.
• Open platform teams use documented open platform APIs.

Getting started

Install with go get -u github.com/ArtisanCloud/PowerWeChat/v3, initialize instance with config, then call API. README points to https://powerwechat.artisan-cloud.com/zh/start/ and https://github.com/ArtisanCloud/power-wechat-tutorial for examples.

When to use it — and when not to

Use when Go service needs broad WeChat API coverage and team wants SDK to handle crypto, signature, callback, token refresh. Avoid when non-Go stack, or when project must implement every WeChat request detail directly. README gives no paid product comparison, no hosted option, no database, storage, or SMTP setup; V2 to V3 upgrade adds context parameter and fixes v2 auto refresh token issue, so older code may need migration.

go get -u github.com/ArtisanCloud/PowerWeChat/v3

import (
	"github.com/ArtisanCloud/PowerWeChat/v3/src/miniProgram"
	"os"
)

// 1. 初始化小程序应用实例
app, err := miniProgram.NewMiniProgram(&miniProgram.UserConfig{
	AppID:  os.Getenv("miniprogram_app_id"), // 小程序、公众号或者企业微信的appid
	Secret: os.Getenv("miniprogram_secret"), // 商户号 appID
	HttpDebug: true,
	Debug:     false,
})

// 2. 调用小程序的授权登陆接口
code := "CODE" // 前端小程序登录时，从微信获取的code
rs, err := app.Auth.Session(code)

printf(rs.OpenID)
