Flutter中极光推送的使用----jpush_flutter

原文地址：https://www.cnblogs.com/niceyoo/p/11095994.html

1、申请极光账号和建立应用

极光推送的官方网址为：https://www.jiguang.cn/

注册好后，进入'服务中心',然后再进入'开发者平台'，点击创建应用。

这时候会出现新页面，让你填写“应用名称”和上传“应用图标”。

创建完成，极光平台就会给我们两个key。

• appKey : 移动客户端使用的key
• Master Secret ： 服务端使用的key

我们这里只做移动端不做服务端，所以只需要appKey。得到这个Key也算是极光平台操作完了

2、加入dependencies依赖

github网址:https://github.com/jpush/jpush-flutter-plugin

要使用极光推送插件必须先下载包，要下载包就需要先添加依赖，直接把下面的代码加入pubspec.yaml文件中。

jpush_flutter: 0.0.11

写完代码后，选择Android Studio右上角的Packages get进行下载，下载完成后进行操作。

3、build.gradle添加可以和cpu型号代码

打开android/app/src/build.gradle文件，加入如下代码：

defaultConfig {
    applicationId "sscai.club.flutter_shop"
    minSdkVersion 16
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    /*新加入的*/
    ndk {
        /*选择要添加的对应 cpu 类型的 .so 库。
        abiFilters 'armeabi', 'armeabi-v7a', 'x86', 'x86_64', 'mips', 'mips64'// 'arm64-v8a',
        /*还可以添加
    }

    manifestPlaceholders = [
        JPUSH_PKGNAME: applicationId,
        JPUSH_APPKEY : "这里写入你自己申请的Key哦", /*NOTE: JPush 上注册的包名对应的 Appkey.*/
        JPUSH_CHANNEL: "developer-default", /*暂时填写默认值即可.*/
    ]
    /*新加入的*/
}

详细请参考：https://github.com/jpush/jpush-flutter-plugin

4、主要代码编写

在 main.dart 中引入依赖

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:jpush_flutter/jpush_flutter.dart';

编写initPlatformState方法

Future<void> initPlatformState() async {
    String platformVersion;

    try {
      /*监听响应方法的编写*/
      jpush.addEventHandler(
          onReceiveNotification: (Map<String, dynamic> message) async {
            print(">>>>>>>>>>>>>>>>>flutter 接收到推送: $message");
            setState(() {
              debugLable = "接收到推送: $message";
            });
          }
      );

    } on PlatformException {
      platformVersion = '平台版本获取失败，请检查！';
    }

    if (!mounted){
      return;
    }

    setState(() {
      debugLable = platformVersion;
    });
}

编写build的视图

@override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('极光推送'),
        ),
        body: new Center(
            child: new Column(
                children:[
                  new Text('结果: $debugLable
'),
                  new RaisedButton(
                      child: new Text(
                          '点击发送推送消息
',
                      ),
                      onPressed: () {
                        /*三秒后出发本地推送*/
                        var fireDate = DateTime.fromMillisecondsSinceEpoch(DateTime.now().millisecondsSinceEpoch + 3000);
                        var localNotification = LocalNotification(
                          id: 234,
                          title: '我是推送测试标题',
                          buildId: 1,
                          content: '看到了说明已经成功了',
                          fireTime: fireDate,
                          subtitle: '一个测试',
                        );
                        jpush.sendLocalNotification(localNotification).then((res) {
                          setState(() {
                            debugLable = res;
                          });
                        });
                      }),
                ]
            )
        ),
      ),
    );
  }

main.dart 完整代码：

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:jpush_flutter/jpush_flutter.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String debugLable = 'Unknown';   /*错误信息*/
  final JPush jpush = new JPush(); /* 初始化极光插件*/
  @override
  void initState() {
    super.initState();
    initPlatformState();  /*极光插件平台初始化*/
  }


  Future<void> initPlatformState() async {
    String platformVersion;

    try {
      /*监听响应方法的编写*/
      jpush.addEventHandler(
          onReceiveNotification: (Map<String, dynamic> message) async {
            print(">>>>>>>>>>>>>>>>>flutter 接收到推送: $message");
            setState(() {
              debugLable = "接收到推送: $message";
            });
          }
      );

    } on PlatformException {
      platformVersion = '平台版本获取失败，请检查！';
    }

    if (!mounted){
      return;
    }

    setState(() {
      debugLable = platformVersion;
    });
  }

  /*编写视图*/
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('极光推送'),
        ),
        body: new Center(
            child: new Column(
                children:[
                  new Text('结果: $debugLable
'),
                  new RaisedButton(
                      child: new Text(
                          '点击发送推送消息
',
                      ),
                      onPressed: () {
                        /*三秒后出发本地推送*/
                        var fireDate = DateTime.fromMillisecondsSinceEpoch(DateTime.now().millisecondsSinceEpoch + 3000);
                        var localNotification = LocalNotification(
                          id: 234,
                          title: '我是推送测试标题',
                          buildId: 1,
                          content: '看到了说明已经成功了',
                          fireTime: fireDate,
                          subtitle: '一个测试',
                        );
                        jpush.sendLocalNotification(localNotification).then((res) {
                          setState(() {
                            debugLable = res;
                          });
                        });
                      }),
                ]
            )
        ),
      ),
    );
  }
}

效果图：

4、扩展几个方法

收到推送提醒

监听addReceiveNotificationListener方法：

/*
* 收到推送提醒
* */
  void _ReceiveNotification() async {
    FlutterJPush.addReceiveNotificationListener(
        (JPushNotification notification) {
      setState(() {
        /// 收到推送
        print("收到推送提醒: $notification");
      });
    });
  }

打开推送提醒

监听 addReceiveNotificationListener方法：

 /*
  * 打开推送提醒
  * */
  void _OpenNotification() async {
    FlutterJPush.addReceiveOpenNotificationListener(
        (JPushNotification notification) {
      setState(() {
        print("打开了推送提醒: $notification");
      });
    });
  }

监听接收自定义消息

一般项目这个方法会用的比较多吧！！！

监听 addReceiveCustomMsgListener方法：

  /*
  * 监听接收自定义消息
  * */
  void _ReceiveCustomMsg() async {
    FlutterJPush.addReceiveCustomMsgListener((JPushMessage msg) {
      setState(() {
        print("收到推送消息提醒: $msg");
      });
    });
  }

实际案例：

import 'dart:convert';

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:jpush_flutter/jpush_flutter.dart';

class PushInfoWidget extends StatefulWidget {
  @override
  _PushInfoWidgetState createState() => new _PushInfoWidgetState();
}

class _PushInfoWidgetState extends State<PushInfoWidget> {
  String debugLable = 'Unknown'; /*错误信息*/
  final JPush jpush = new JPush(); /* 初始化极光插件*/
  @override
  void initState() {
    super.initState();
    jpush.setup(
        appKey: '自己的',
        channel: 'developer-default',
        production: true,
        debug: false);
    initPlatformState(); /*极光插件平台初始化*/
  }

  Future<void> initPlatformState() async {
    String platformVersion;
    try {
      /*监听响应方法的编写*/
      jpush.addEventHandler(
        onReceiveNotification: (Map<String, dynamic> message) async {
          print(">>>>>>>>>>>>>>>>>flutter 接收到推送: $message");
          setState(() {
            debugLable = "接收到推送: $message";
          });
        },

        /// 点击通知栏消息，在此时通常可以做一些页面跳转等
        onOpenNotification: (Map<String, dynamic> message) async {
          print(">>>>>>>>>>>>>>>>>点击之后拿到的消息内容");
          print(int.parse(json.decode(message['extras']['cn.jpush.android.EXTRA'])['id']));
          Navigator.pushNamed(context, '/messageDetail', arguments: {
            "id":  int.parse(json.decode(message['extras']['cn.jpush.android.EXTRA'])['id'])
          });
        },
      );
    } on PlatformException {
      platformVersion = '平台版本获取失败，请检查！';
    }

    if (!mounted) {
      return;
    }

    setState(() {
      debugLable = platformVersion;
    });
  }


  /*编写视图*/
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('极光推送'),
        ),
        body: new Center(
            child: new Column(children: [
          new Text('结果: $debugLable
'),
          new RaisedButton(
              child: new Text(
                '点击发送推送消息
',
              ),
              onPressed: () {
                /*三秒后出发本地推送*/
                var fireDate = DateTime.fromMillisecondsSinceEpoch(
                    DateTime.now().millisecondsSinceEpoch + 3000);
                var localNotification = LocalNotification(
                  id: 234,
                  title: '我是推送测试标题',
                  buildId: 1,
                  content: '看到了说明已经成功了',
                  fireTime: fireDate,
                  subtitle: '一个测试',
                );
                jpush.sendLocalNotification(localNotification).then((res) {
                  setState(() {
                    debugLable = res;
                  });
                });
              }),
        ])),
      ),
    );
  }
}
