@cvo/plugin-wechat

WeChat integration plugin for CVO Framework, providing Mini Program authorization and PC Web scan-to-login functionality.

🚀 Features

• Mini Program Auth: Easily exchange code for openid and unionid.
• PC Web Login: Quickly generate WeChat scan-to-login redirect URLs.
• Structured Service: Encapsulates complex WeChat APIs into a clean WechatService.
• Built-in HTTP Client: Uses axios for robust communication.

🛠 Configuration

Register the plugin in your cvo.config.ts:

import { defineConfig } from '@cvo/core';
import { WechatPlugin } from '@cvo/plugin-wechat';

export default defineConfig({
  plugins: [
    new WechatPlugin({
      appid: process.env.WECHAT_APPID!,
      secret: process.env.WECHAT_SECRET!
    })
  ]
});

🧠 Usage

Mini Program Login

Access the service via useWechat() in your API handlers:

import { useWechat } from '@cvo/plugin-wechat';

export async function login(code: string) {
  const wechat = useWechat();
  const service = wechat.getService();
```,old_str:
  
  // Exchange code for WeChat OpenID
  const openid = await service.getOpenid(code);
  
  // Find or create user by openid...
  return { openid };
}

PC Web Scan Login

Generate the redirect URL for the WeChat login page:

import { useWechat } from '@cvo/plugin-wechat';

export async function getLoginUrl() {
  const wechat = useWechat();
  const service = wechat.getService();
  
  const redirectUri = 'https://myapp.com/api/wechat/callback';
  const state = 'random-string-for-security';
  
  const url = service.getPcLoginUrl(redirectUri, state);
  return { url };
}

🛠 Advanced: Custom WeChat Service

If you need to extend WeChat functionality (e.g., Pay, Template Messages), you can inherit from WechatService:

import { WechatService, WechatPlugin } from '@cvo/plugin-wechat';

class MyAdvancedWechatService extends WechatService {
  async sendTemplateMessage(to: string, data: any) {
    // Custom logic...
  }
}

Note: If you need custom service injection, consider manually registering your service using CVO's InjectorRegistry.
