uniapp realizes the call recording function

Recently, I need to implement a function of calling the mobile phone to make a call through uniapp. After making the call, it will be recorded at the same time. After hanging up the call, Upload the recording file and now share some core codes with everyone!

const recorderManager = uni.getRecorderManager();
onLoad(option) {
            let self = this;
            recorderManager.onStop(function (res) {
                console.log("res",res)
                self.end_time = Math.round(new Date().getTime() / 1000);
                let voicePath = res.tempFilePath;
                self.voicePath = voicePath;
                self.closeTimeOut();
                uni.showToast({
                    icon: 'loading',
                    title: "请稍后...",
                    duration: 0
                });
                uni.uploadFile({
                    url: self.upload_url,
                    filePath: voicePath,
                    name: "file",
                    formData: {
                        id: self.phoneInfo.id,
                        start_time: self.start_time,
                        end_time: self.end_time,
                        phone: self.phoneNumber
                    },
                    header: {
                        Authorization: "Bearer " + uni.getStorageSync(EnumData.token)
                    },
                    success: (res) => {
                        // console.log("文件上传成功")
                        console.log(res.data);
                    },
                    fail(err) {
                        console.log("文件上传失败")
                        console.log(err);
                    },
                    complete() {
                        self.start_time = 0;
                        self.end_time = 0;
                        uni.hideToast();
                    }
                })
            });
            this.getCallStatus();
}
getCallStatus() {
    let that = this;
    let maintest = plus.android.runtimeMainActivity();
    let Contexttest = plus.android.importClass("android.content.Context");
    let telephonyManager = plus.android.importClass("android.telephony.TelephonyManager");
    let telManager = plus.android.runtimeMainActivity().getSystemService(Contexttest.TELEPHONY_SERVICE);
    let receiver = plus.android.implements('io.dcloud.android.content.BroadcastReceiver', {
        onReceive: function (Contexttest, intent) {
            plus.android.importClass(intent);
            let phoneStatus = telManager.getCallState();
            that.callStatus = phoneStatus; //电话状态 0->空闲状态 1->振铃状态 2->通话存在
            switch (phoneStatus) {
                case 0:
                    console.log("3、电话挂断，上传录音")
                    // 结束录音
                    recorderManager.stop();
                    break;
                case 1:
                    // console.log('1、振铃状态');
                    break;
                case 2:
                    console.log('2、通话存在')
                    // 延迟录音
                    that.start_time = Math.round(new Date().getTime() / 1000);
                    recorderManager.start({
                        duration: EnumData.audioDuration, // 时长 10分钟
                        sampleRate: EnumData.audioSampleRate, // 码率
                    });
                    break;
            }
        }
    });
    let IntentFilter = plus.android.importClass('android.content.IntentFilter');
    let filter = new IntentFilter();
    filter.addAction(telephonyManager.ACTION_PHONE_STATE_CHANGED);
    maintest.registerReceiver(receiver, filter);
},

The permissions you need to apply for can be placed in App.vue

if (plus.os.name == 'Android') {
      plus.android.requestPermissions(
         ['android.permission.ANSWER_PHONE_CALLS',//手动 挂断和接听 需要这个权限
          "android.permission.MODIFY_AUDIO_SETTINGS",//手动 挂断和接听 需要这个权限
          "android.permission.CALL_PHONE",//手动 挂断和接听 需要这个权限
          "android.permission.READ_PHONE_STATE",//>监听电话状态 需要这个权限
          "android.permission.READ_CALL_LOG",//获取号码需要这个权限
          "android.permission.READ_AUDIO" // 录音权限
          ],
      function(resultObj) {
          var result = 0;
          for (var i = 0; i < resultObj.granted.length; i++) {
          var grantedPermission = resultObj.granted[i];
          console.log(&#39;已获取的权限：&#39; + grantedPermission);
          result = 1
      }
      for (var i = 0; i < resultObj.deniedPresent.length; i++) {
          var deniedPresentPermission = resultObj.deniedPresent[i];
          console.log(&#39;拒绝本次申请的权限：&#39; + deniedPresentPermission);
          result = 0
      }
      for (var i = 0; i < resultObj.deniedAlways.length; i++) {
          var deniedAlwaysPermission = resultObj.deniedAlways[i];
          console.log(&#39;永久拒绝申请的权限：&#39; + deniedAlwaysPermission);
          result = -1
      }
     },  function(error) {
          console.log(&#39;申请权限错误：&#39; + error.code + " = " + error.message);
     } );
}

Note

• It can be used in debug mode It normally monitors call hang-ups and uploads files, but it becomes invalid after packaging?

General mobile phone packaging can be used normally. I use oneplus7. After packaging, it can be installed and used normally. Some mobile phones need to go to the permissions of the system settings and change the application's [Open the phone [Device Status Code] Just turn it on. This is what I have encountered so far.
