Question

我目前正在开发一个Ionic 2应用程序项目，该项目允许用户录制自己的声音，停止录制并播放该声音。根据离子原生，我可以看到它们提供了2个插件，即MediaPlugin和MediaCapture。我已经尝试过使用MediaPlugin但是我在启动记录时遇到了问题，停止并播放它。有没有人使用过这个插件？我已经浏览了离子文档和其他一些博客，但我仍然无法做到。我对此非常陌生，非常感谢你的努力。我很感激你的想法。

此致

这是我的home.ts代码：

import {NavController, Platform, Page, Events} from 'ionic-angular';
import {MediaPlugin} from 'ionic-native';

@Component({

})
export class HomePage {
    private _platform: Platform;
    private _fileRecord: MediaPlugin;
    private _pathFile: string;
    private _nameFile: string;
  constructor(private navCtrl: NavController, platform: Platform) {
     this._platform = platform;
  }
  public startRecord(): void {
     this._pathFile = this.getPathFileRecordAudio();
     this._fileRecord = new MediaPlugin(this._pathFile);
     this._fileRecord.startRecord();
  }

  public stopRecord(): void {
     this._fileRecord.stopRecord();
  }

  private startPlay(): void {
     this._fileRecord = new MediaPlugin(this._pathFile);
     this._fileRecord.play();
  }

  private getPathFileRecordAudio(): string {
     let path: string = (this._platform.is('ios') ? '../Library/NoCloud/': '../Documents/');
     return path + this._nameFile + '-' + '.wav';
  }
 }

您是否在source中查看了该插件的评论？有关于如何调整事物的说明......有人有类似的here，但你提供了更多有关错误的详细信息。（我将评论复制到答案中）。

如何在Ionic 2上录制音频和播放？
