angularjs - ionic 应用程序不允许访问照片数据

Question

我正在使用此代码从 dataUrl 保存图像，它给出错误权限被拒绝。如何使用此 dataUrl 将图像保存在应用程序文件夹中？

this.PhotoLibrary.requestAuthorization().then(() => {
   this.PhotoLibrary.saveImage(dataUrl,'MyHomeLibrary',options).then((data) => {
     console.log('data',data);

  })
  .catch(err => console.log(err));
    // Do stuff after you have permission!
    })

我遇到了同样的问题，并且能够通过这样做来解决它

this.photoLibrary.requestAuthorization({read:true,write:true})

在这里找到答案 - Android oreo : Permission Denial: This application is not allowed to access Photo data.

更新:

From Android O we have to call request Authorization method like below

this.photoLibrary.requestAuthorization()

The Above method need to replace with

this.photoLibrary.requestAuthorization({read:true,write:true})
