本篇文章给大家带来了关于uniapp的相关知识，其中主要跟大家介绍uniapp怎么实现打电话录音功能，感兴趣的朋友下面一起来看一下吧，希望对大家有帮助。

最近需要实现一个通过uniapp调用手机拨打电话的功能，拨打之后同时录音，挂断电话之后将录音文件进行上传，现在将几个核心代码分享给大家，希望对大家有帮助

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);
},

需要申请的权限，可以放到 App.vue 中

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('已获取的权限：' + grantedPermission);
          result = 1
      }
      for (var i = 0; i < resultObj.deniedPresent.length; i++) {
          var deniedPresentPermission = resultObj.deniedPresent[i];
          console.log('拒绝本次申请的权限：' + deniedPresentPermission);
          result = 0
      }
      for (var i = 0; i < resultObj.deniedAlways.length; i++) {
          var deniedAlwaysPermission = resultObj.deniedAlways[i];
          console.log('永久拒绝申请的权限：' + deniedAlwaysPermission);
          result = -1
      }
     },  function(error) {
          console.log('申请权限错误：' + error.code + " = " + error.message);
     } );
}

注意点
