## 背景
|
|
|
|
|
|
|
|
|
|
|
|
本文我们将开一下脑洞，在 ReactNative 工程基础上下集成及运行小程序方案。
|
|
|
|
|
|
|
|
|
|
|
|
先看一下效果如下:

|
|
|
|
|
|
|
|
|
|

官方的[环境搭建文档](https://reactnative.dev/docs/environment-setup)已经有详细的说明，这里不再重复。大家可以看下我本地的环境配置版本，目前整个项目运行稳定，可以借鉴。

## 新建 ReactNative 样例工程
|
|
|
|

|
|
|
|
|
|
|
### 新建 ReactNative 工程
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
|
|
|
|
|
|
react-native init mopdemo
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
稍等一会...
|
|
|
|
|
|
|
|
|
|
|
|
初始化项目完成之后，你可以选择两种不同的方式运行 App 在 iOS/Android 平台：
|
|
|
|
|
|
|
|
|
|
|
|
注意！ReactNative需要依赖本地安装对应的 iOS,Android 开发工具，即需要安装 Xcode 和 AndroidStudio。具体安装使用方法这里不赘述。
|
|
|
|
|
|
|
|
|
|
|
|
这里我们用 VSCode+Xcode 作为开发组合环境。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 集成小程序解析引擎
|
|
|
|
|
|
|
|
|
|
|
|
这里我们采用凡泰集成免费社区版的小程序解析引擎，只需要 10 行代码量不到即可完成小程序集成。
|
|
|
|
|
|
|
|
|
|
|
|
1. 引入小程序引擎插件。在 package.json 文件中引入小程序 ReactNative 插件
|
|
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
|
"react-native-mopsdk": "^1.0.1"
|
|
|
|
|
|
```
|
|
|
|
|
|
|

|
|
|
|
2. 在 main.dart 文件中增加以下小程序引擎初始化方法。 Mop.instance.initialize 这里需要用到 sdkkey 和 secret。可以直接在[https://mp.finogeeks.com](https://mp.finogeeks.com) 免费注册获取。注册使用方法可以参考 [接入指引](https://mp.finogeeks.com/mop/document/introduce/access/mechanism.html)
|
2020-04-13 20:00:02 +08:00
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
|
import MopSDK from 'react-native-mopsdk';
|
|
|
|
|
|
// 1. mop初始化
|
|
|
|
|
|
MopSDK.initialize({
|
|
|
|
|
|
appkey: '22LyZEib0gLTQdU3MUauASlb4KFRNRajt4RmY6UDSucA',
|
|
|
|
|
|
secret: '4a915e447bcbd439',
|
|
|
|
|
|
apiServer: 'https://mp.finogeeks.com',
|
|
|
|
|
|
apiPrefix: '/api/v1/mop'
|
|
|
|
|
|
}, (data) => {
|
|
|
|
|
|
console.log('message;', data);
|
|
|
|
|
|
});
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
3. 打开小程序
|
|
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
|
MopSDK.openApplet('appid','','',(data)=>{});
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
* **SDKKEY** 和 **Secret** 可以从前面部署的社区版的管理后台获取。
|
|
|
|
|
|
* **apiServer** 为这里是小程序生态后端的服务地址也就是前文所输入的`IP:端口`。
|
|
|
|
|
|
* **小程序id** 为在管理后台上架的小程序唯一ID(在小程序小架时自动生成)
|
|
|
|
|
|
* 上述的参数可以在前文服务器部署的后台界面上获取，亦可以在没有部署服务端的情况下在[https://mp.finogeeks.com](https://mp.finogeeks.com)快速注册，免费获取。
|
|
|
|
|
|
* **重要事情说三遍，您可以在官方的github仓库中查看示例代码** [https://github.com/finogeeks/mop-react-native-demo](https://github.com/finogeeks/mop-react-native-demo)
