Android 如何显示Cordova PhotoLibrary返回的图像?
我似乎在Android上的图像库中显示图像时遇到问题。PhotoLibrary插件返回文件列表,但当我将图像URL提供给Android 如何显示Cordova PhotoLibrary返回的图像?,android,angular,cordova,typescript,ionic3,Android,Angular,Cordova,Typescript,Ionic3,我似乎在Android上的图像库中显示图像时遇到问题。PhotoLibrary插件返回文件列表,但当我将图像URL提供给img标记时,它们不会加载 window['cordova']['plugins']['photoLibrary'].getLibrary( result => console.log(libraryItem), err => console.log(err);
img
标记时,它们不会加载
window['cordova']['plugins']['photoLibrary'].getLibrary(
result => console.log(libraryItem),
err => console.log(err);
},
{
thumbnailWidth: 512,
thumbnailHeight: 384,
quality: 0.8,
includeAlbumData: true
});
这将检索图像的URL,但它们不能用于实际显示它们。我得到的东西有:
creationDate: Fri Nov 03 2017 20:06:01 GMT-0400 (EDT)
fileName: "2017-10-4-1.jpg"
height: 960
id: "1907;/storage/emulated/0/Pictures/Timelapser/2017-10-4-1.jpg"
latitude: 0
longitude: 0
photoURL: "cdvphotolibrary://photo?photoId=1907%3B%2Fstorage%2Femulated%2F0%2FPictures%2FTimelapser%2F2017-10-4-1.jpg"
thumbnailURL: "cdvphotolibrary://thumbnail?photoId=1907%3B%2Fstorage%2Femulated%2F0%2FPictures%2FTimelapser%2F2017-10-4-1.jpg&width=512&height=384&quality=0.8"
width: 1280
将photoURL
或thumbnailURL
馈送到img src
不起作用。我试图解码URI
它们,使用之前或之后的部分
和nothing.您需要使用插件和cdvphotolibrary
管道,如下所示
这里有工作
html
cdv-photo-library.ts(pipe
)
有人知道如何用Quasar/Vue和Cordova做到这一点吗?
<ion-grid no-padding margin-top>
<ion-row class="row">
<ion-col col-6 *ngFor="let data of library">
<img [src]="data?.thumbnailURL | cdvPhotoLibrary">
</ion-col>
</ion-row>
</ion-grid>

this.platform.ready().then(() => {
this.library = [];
this.photoLibrary.getLibrary({ thumbnailWidth: THUMBNAIL_WIDTH, thumbnailHeight: THUMBNAIL_HEIGHT }).subscribe({
next: (chunk) => {
this.library = this.library.concat(chunk);
this.cd.detectChanges();
},
error: (err: string) => {
if (err.startsWith('Permission')) {
this.platform.ready().then(() => {
this.photoLibrary.requestAuthorization({ read: true })
.then(() => {

let message = 'requestAuthorization error: ${err}';
this.showToast.showErrorToast(message);
});
});
} else { // Real error

},
complete: () => {
// Library completely loaded
}
});
});
