ionic3 fileTransfer.download ios无法下载也没有异常报出
作者:互联网
安卓端没有问题,但在IOS系统中点击下载没有反应,也没有任何异常,解决方法:fileTransfer在调用时再实例化即可;
@Component({
selector: 'page-home',
templateUrl: 'home.html',
providers: [FileTransfer, File]
})
export class HomePage {
private fileTransfer: FileTransferObject;
...
...
constructor(public navCtrl: NavController, private transfer: FileTransfer, private file: File, private alertCtrl: AlertController, private platform: Platform) {
...
}
downloadFile() {
// using a local constant is also a valid alternative,
// the important thing is to instantiate the object at this time
// const fileTransfer: FileTransferObject = this.transfer.create();
this.fileTransfer = this.transfer.create();
this.fileTransfer.download(url, nativeUrl,true).then((entry) => {
console.log(nativeUrl);
let fileType = fileName.substr(fileName.lastIndexOf(".")+1);
// entry.nativeURL 是上面那个插件文件下载后的保存路径
this.loading_end();
this.fileOpener.open(nativeUrl, this.getFileMimeType(fileType))
.then(() => {
console.log('打开成功');
this.loading_end();
})
.catch(err => {
console.log(err);
this.loading_end();
this.showAlertFirst(err,null);
});
}, (error) => {
this.showAlertFirst('下载失败',null);
this.loading_end();
console.log(error);
});
}
}
