概要

用react-native-push-notification实现通知推送功能，类似的还有Firebase和OneSignal。但它们似乎都需要去官网注册一个App项目，使它们具有发送通知的功能。

虽然成功了，但其实没太弄明白，做个简单记录。

---

整体架构流程

1、初始化

初始化一个App项目。

npx react-native@0.73 init OUC

2、依赖

下载依赖。（第二个不一定需要）

yarn add react-native-push-notification

yarn add react-native-onesignal

3、注册

去官网注册，这次是在Firebase官网注册。

生效的似乎是第三个应用com.ouc。先前注册另外几个应用后yarn android都报错：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugGoogleServices'.
> No matching client found for package name 'com.ouc'

* Try:

> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
> Get more help at https://help.gradle.org.

BUILD FAILED in 4s

故而本人认为需要注意大小写，猜测以.ouc结尾就行，比如说com.study.ouc。

4、配置

将下载的google-services.json放入/android/app目录下。
配置：
/android/build.gradle

buildscript {

    ...
    
    dependencies {
        
        ...
        
        classpath("com.google.gms:google-services:4.3.2")
    }
}
...

/android/app/build.gradle

...
apply plugin: 'com.google.gms.google-services'

...

dependencies {
    
    ...
    
    implementation("com.google.firebase:firebase-core:9.6.1")
    implementation('com.google.firebase:firebase-analytics')
    implementation platform('com.google.firebase:firebase-bom:33.0.0')

    ...
}

5、功能

功能实现参考来自github大佬代码

小结

总体参考了一个大佬英文教程，还有中文翻译版本的。不过感觉文章似乎有点老，有些地方照搬会出问题。

gmail注册了一晚上，注册和配置搞了一上午。
成功以后有种如释重负的感觉……
