Question

您好，我使用的追随代码无法正常工作。如何重设密码。

 fileTransfer.download(url, path + 'abcd.pdf').then((entry) => {
            let localUrl = entry.toURL();
            const toast = this.toast.create({
              message: 'Download Complted',
              duration: 20000,
              position: 'top',
              closeButtonText: 'OK',
              showCloseButton: true,
            });
            toast.present();
            this.document.viewDocument(localUrl, 'application/pdf', {});
        }, (error) => {
            // handle error
            console.log("In error");
            console.log(error);
            alert(JSON.stringify(error));
        });

如何工作！

您是否在项目中添加了文档查看器插件？请查看此链接https://ionicframework.com/docs/native/document-viewer/，您可以找到命令。

ionic cordova plugin add cordova-plugin-document-viewer
npm install --save @ionic-native/document-viewer

然后，您还必须在viewDocument函数中传递选项

      fileTransfer.download(url, path + 'abcd.pdf').then((entry) => {
            let localUrl = entry.toURL();
            const toast = this.toast.create({
              message: 'Download Complted',
              duration: 20000,
              position: 'top',
              closeButtonText: 'OK',
              showCloseButton: true,
            });
            toast.present();
             const options: DocumentViewerOptions = {
             title: 'My PDF'
            }
            this.document.viewDocument(localUrl, 'application/pdf', options);
        }, (error) => {
            // handle error
            console.log("In error");
            console.log(error);
            alert(JSON.stringify(error));
        });

希望这对您有用！
