expo-react-native-wechat

本库为 expo react native 项目提供 Wechat SDK 支持, 集成了微信SDK:

Android SDK 6.8.23 +
iOS SDK 2.0.2 +

安装

$ npx expo install expo-react-native-wechat

或

$ yarn add expo-react-native-wechat

或

$ npm install expo-react-native-wechat --save

设置iOS Universal Links

1、苹果开发者后台开启Associated Domains，查看项目TeamID

https://developer.apple.com/account/resources/identifiers/list

Set Associated Domains

2、创建文件【apple-app-site-association】（这一步需要后台人员配合）

{
   "applinks": {
       "apps": [],
       "details": [
           {
               "appID": "8P7343TG54.com.tencent.xin.SDKSample",
               "paths": [ "/test/*" ]
           }
       ]
   }
}

将上面的JSON保存为【apple-app-site-association】文件放到网站【.well-known】目录或者网站根目录中

注意事项：

（1）apple-app-site-association文件没有后缀名，appID前面部分是在开发者后台查看的TeamID, 后面部分是iOS项目的bundleId

（2）把【apple-app-site-association】文件放到网站【.well-known】目录或者网站根目录中

（3）域名必须支持https，保证下面路径可以访问: https://help.wechat.com/.well-known/apple-app-site-association 或 https://help.wechat.com/apple-app-site-association

（4）验证方式,通过下面链接可以查看我们设置的文件内容就说明成功了：https://app-site-association.cdn-apple.com/a/v1/help.wechat.com ，因苹果Universal Links更新机制，文件放好后不会立即生效，如果验证不过，可以过两天再试。

3、在Xcode中设置Associated Domains域名（放apple-app-site-association文件的域名）

在XCode中的 Targets > Signing & Capabilitles > Associated Domains > 添加【applinks:www.baidu.com】

Set Associated Domains

在expo中一键配置

1、在项目根目录的【app.json】中添加如下配置

{
    "expo":{
    ....
        "ios": {
          "infoPlist": {
            "LSApplicationQueriesSchemes": ["weixin", "weixinULAPI", "weixinURLParamsAPI"],
            "CFBundleURLTypes": [
              {
                "CFBundleTypeRole": "Editor",
                "CFBundleURLName": "wexin",
                "CFBundleURLSchemes": ["wx54d90c03e686b854"]
              }
            ]
          }
        },
    ....
    }
}

Set URL Types in XCode

2、执行命令

$ npx expo prebuild

在react native中手动配置

RN ios配置

1、在XCode中的 Targets > info > URL type > URL Schema 添加微信的AppID

Set URL Types in XCode

或者在Info.plist文件中添加：

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLName</key>
        <string>wexin</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>wx54d90c03e686b854</string>
        </array>
    </dict>
</array>

2、在XCode中的 Targets > info > Custom iOS Target Properties 添加 Queried URL Schemes 下面添加 weixin、weixinULAPI、weixinURLParamsAPI

Set URL Schemas in XCode

或者在Info.plist文件中添加：

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>weixin</string>
    <string>weixinULAPI</string>
    <string>weixinURLParamsAPI</string>
</array>

RN android配置

android无需额外配置。

调用库

import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';

export default function App() {
    return (

                    console.log("==registerApp==>",a);
                });
            }}>registerApp</Text>
            <Text onPress={()=>{

            }}>shareText</Text>
            <StatusBar style="auto" />
        </View>
    );
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        backgroundColor: '#fff',
        alignItems: 'center',
        justifyContent: 'center',
    },
});

API 文档

本库支持 TypeScript，使用 Promise 或 async/await 来接收返回。

接口名称和参数尽量跟腾讯官网保持一致性，除了嵌套对象变成扁平对象，你可以直接查看腾讯文档来获得更多帮助。

回调事件订阅

从小程序回到 APP，或者支付成功回到 APP 都会触发回调事件来返回相应信息，请在触发相应方法前提前添加事件队列。

    WeChat.registerApp(Global.APP_ID, Global.UNIVERSAL_LINK);
    DeviceEventEmitter.addListener('WeChat_Req', req => {
      console.log('req:', req)
      if (req.type === 'LaunchFromWX.Req') { // 从小程序回到APP的事件
        miniProgramCallback(req.extMsg)
      }
    });
    DeviceEventEmitter.addListener('WeChat_Resp', resp => {
      console.log('res:', resp)
      if (resp.type === 'WXLaunchMiniProgramReq.Resp') { // 从小程序回到APP的事件
        miniProgramCallback(resp.extMsg)
      } else if (resp.type === 'SendMessageToWX.Resp') { // 发送微信消息后的事件
        sendMessageCallback(resp.country)
      } else if (resp.type === 'PayReq.Resp') { // 支付回调
        payCallback(resp)
      }
    });
