[![NPM Version](https://img.shields.io/npm/v/@uiw/react-native-alipay.svg)](https://npmjs.org/package/@uiw/react-native-alipay)

基于 React Native 的宝支付插件，支持 iOS/Android。适用于商家在 App 应用中集成支付宝支付功能，商家 APP 调用支付宝提供的 SDK，SDK 再调用支付宝 APP 内的支付模块。如果用户已安装支付宝APP，商家APP会跳转到支付宝中完成支付，支付完后跳回到商家 APP 内，最后展示支付结果。如果用户没有安装支付宝 APP，商家 APP 内会调起支付宝网页支付收银台，用户登录支付宝账户，支付完后展示支付结果。完整实例 [Example](./example)

## API

### `Alipay.alipay` 支付

> `Alipay.alipay: (payInfo: string) => Promise<OrderResult>;`

- ⚠️ 注意支付成功返回结果是一个字符串，[返回内容](https://github.com/uiwjs/react-native-alipay/blob/74140a294e850884ed1851b9d2c2d2c00ee75003/index.d.ts#L50-L74)  
- ⚠️ 支付宝需要设置 `Scheme` 和 iOS添加原生代码，才能支持支付和[回弹商家APP](#支付宝返回应用-ios-设置)的功能
- ⚠️ 支付宝 `管理中心-支付宝开放平台` 需要签约 [`APP支付`](https://opendocs.alipay.com/open/200/105310#%E6%B7%BB%E5%8A%A0%E5%BA%94%E7%94%A8%E5%8A%9F%E8%83%BD)

```javascript
import Alipay from '@uiw/react-native-alipay';

// 设置 支付宝 URL Schemes，要表述他是宇宙唯一性，可以使用 `bundle Identifier`
// scheme = `alipay` + `APPID`，`APPID` 为支付宝分配给开发者的应用ID
Alipay.setAlipayScheme(scheme);
// ⚠️ 目前不可用，设置支付宝沙箱环境，仅 Android 支持
// Alipay.setAlipaySandbox(isSandbox);

- ⚠️ 后台 SDK 根据所有数据生成 `sign`，建议通过 API 拿到这个数据，拼接数据会报错。  
- ⚠️ `out_trade_no` 订单 id 和 `sign` 签名 是唯一的，每次不一样，需要后台生成。

### `Alipay.getVersion` 获取 SDK 版本

> `Alipay.getVersion: () => Promise<string>;`

```js
import Alipay from '@uiw/react-native-alipay';

async function getVersion() {
  const version = await Alipay.getVersion();
  console.log('version:', version);
}
```

## 支付宝返回应用 iOS 设置

- ⚠️ Android 端不需要做任何设置。
- ⚠️ 如果用户从 `支付宝App` 跳转到 `商家APP`，是通过系统功能切换，而不是通过 `支付宝APP` 功能键返回 `商家APP`，回调函数是不起作用的，可通过 [`AppState.addEventListener`](https://github.com/uiwjs/react-native-alipay/blob/5daea87bf0af05d60d0ae9e4c04e1e2d1a6e4273/example/App.js#L8-L24) 监听事件请求后台 API，来优化这一用户体验。

1. 在代码中设置支付宝 [`URL Schemes`](https://github.com/uiwjs/react-native-alipay/blob/74140a294e850884ed1851b9d2c2d2c00ee75003/example/App.js#L7)，下面实例 [`uiwjspay`](https://github.com/uiwjs/react-native-alipay/commit/f6d21b6b7ec7236b195c56281f971092f3c9bb08) 是定义的 `scheme`，你也可以定义为 `alipay` + `appid`，`appid` 为支付宝分配给开发者的应用ID，用来表述 `scheme` 唯一性。

```js
Alipay.setAlipayScheme('uiwjspay');
```

2. 在请求支付的 [`payInfo`](https://github.com/uiwjs/react-native-alipay/blob/74140a294e850884ed1851b9d2c2d2c00ee75003/example/App.js#L11) 中必须包含 [`return_url=uiwjspay://`](https://github.com/uiwjs/react-native-alipay/blob/74140a294e850884ed1851b9d2c2d2c00ee75003/example/App.js#L11)，`return_url` 的值为定义的 `scheme` => `uiwjspay://`，才会返回[支付宝订单支付状态结果](https://opendocs.alipay.com/open/204/105301#%E8%BF%94%E5%9B%9E%E7%BB%93%E6%9E%9C%E7%A4%BA%E4%BE%8B%EF%BC%88iOS%7CAndroid%EF%BC%89)

```js
// payInfo 是后台拼接好的支付参数，这个参数必须包含 `return_url=uiwjspay://`
Alipay.alipay(payInfo, (res)=>console.log(res))
```

3. 用的 `URL Schemes` 列为白名单，在 [`ios/<应用名称>/Info.plist`](https://github.com/uiwjs/react-native-alipay/blob/74140a294e850884ed1851b9d2c2d2c00ee75003/example/ios/example/Info.plist#L23-L41) 中添加

```xml
<key>LSApplicationQueriesSchemes</key>
<array>
  <string>alipay</string>
</array>
<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string></string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>uiwjspay</string>
    </array>
  </dict>
</array>
```

4. 修改 [`ios/<应用名称>/AppDelegate.m`](https://github.com/uiwjs/react-native-alipay/blob/74140a294e850884ed1851b9d2c2d2c00ee75003/example/ios/example/AppDelegate.m#L60-L70) 添加下列代码：

```objective-c
#import <React/RCTLinkingManager.h>

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
  return [RCTLinkingManager application:application openURL:url
                      sourceApplication:sourceApplication annotation:annotation];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options
{
  return [RCTLinkingManager application:application openURL:url options:options];
}
```

**命令测试**

- iOS: `xcrun simctl openurl booted uiwjspay://`
- Android：`adb shell am start -W -a android.intent.action.VIEW -d "uiwjspay://test/router" com.uiwjspay`

## 错误处理

```bash
[NetworkInfo] Signal strength query returned error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied", descriptor: <CTServiceDescriptor 0x283317100, domain=1, instance=1>
```

在 `Product` -> `Scheme` -> `Edit Scheme` -> `Run` -> `Arguments` -> `Environment Variables` 添加 `OS_ACTIVITY_MODE` `disable`

## 其它

当前工程基于 [@brodybits/create-react-native-module](https://github.com/brodybits/create-react-native-module) 初始化。

```bash
npx create-react-native-module --package-identifier com.uiwjs --generate-example Alipay --example-react-native-version 0.62.2 --module-name react-native-uiwjs-alipay --github-account uiwjs --author-name "Kenny Wong" --author-email "wowohoo@qq.com"
```
