快速入门

安装

你可以使用我们的 AI 辅助设置来安装插件。使用以下命令将 Capgo skills 添加到你的 AI 工具中：

bunx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下 prompt：

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-wechat` plugin in my project.

如果你更想手动设置，请运行以下命令安装插件，并按照下方各平台的说明操作：

bun add @capgo/capacitor-wechat
bunx cap sync

导入

import { CapacitorWechat } from '@capgo/capacitor-wechat';

快速入门

import { CapacitorWechat } from '@capgo/capacitor-wechat';

await CapacitorWechat.initialize({
  appId: 'wx1234567890',
  universalLink: 'https://example.com/app/'
});

示例：isInstalled

import { CapacitorWechat } from '@capgo/capacitor-wechat';

const { installed } = await CapacitorWechat.isInstalled();
if (installed) {
  console.log('WeChat is installed');
}

示例：auth

import { CapacitorWechat } from '@capgo/capacitor-wechat';

const { code, state } = await CapacitorWechat.auth({
  scope: 'snsapi_userinfo',
  state: 'my_state'
});
// Use code to get access token from your server

常见坑点

• 初始化一次: 在应用启动时运行 setup。
• 原生同步：运行 bunx cap sync 在插件升级后。
• 唯一可信来源：信任 src/definitions.ts 在 GitHub 仓库中。

API 概览

initialize

使用应用凭据初始化 WeChat SDK。

你也可以在 capacitor.config.ts 下的 CapacitorWechat 插件配置中设置这些值。在运行时调用此方法会覆盖任何已打包的配置。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

await CapacitorWechat.initialize({
  appId: 'wx1234567890',
  universalLink: 'https://example.com/app/'
});

isInstalled

检查设备是否已安装微信。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

const { installed } = await CapacitorWechat.isInstalled();
if (installed) {
  console.log('WeChat is installed');
}

auth

使用微信 OAuth 验证用户身份。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

const { code, state } = await CapacitorWechat.auth({
  scope: 'snsapi_userinfo',
  state: 'my_state'
});
// Use code to get access token from your server

share

将内容分享至微信。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

// Share text
await CapacitorWechat.share({
  scene: 0, // 0 = Session, 1 = Timeline, 2 = Favorite
  type: 'text',
  text: 'Hello WeChat!'
});

// Share link
await CapacitorWechat.share({
  scene: 1,
  type: 'link',
  title: 'My Website',
  description: 'Check out my website',
  link: 'https://example.com',
  imageUrl: 'https://example.com/image.jpg'
});

sendPaymentRequest

向微信支付发起支付请求。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

// Get payment params from your server first
const paymentParams = await fetchPaymentParamsFromServer();

await CapacitorWechat.sendPaymentRequest({
  partnerId: paymentParams.partnerId,
  prepayId: paymentParams.prepayId,
  nonceStr: paymentParams.nonceStr,
  timeStamp: paymentParams.timeStamp,
  package: paymentParams.package,
  sign: paymentParams.sign
});

openMiniProgram

打开微信小程序。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

const { extMsg } = await CapacitorWechat.openMiniProgram({
  username: 'gh_xxxxxxxxxxxxx',
  path: 'pages/index/index',
  type: 0 // 0 = Release, 1 = Test, 2 = Preview
});

chooseInvoice

从微信中选择发票。

import { CapacitorWechat } from '@capgo/capacitor-wechat';

const { cards } = await CapacitorWechat.chooseInvoice({
  appId: 'your_app_id',
  signType: 'SHA1',
  cardSign: 'signature',
  timeStamp: '1234567890',
  nonceStr: 'random_string'
});
console.log('Selected cards:', cards);
