如何使用InappBrowser打开本地PDF

Question

我已经使用传输插件从服务器下载了一个PDF文件，并且我正在尝试使用Inappbrower插件打开文件，我什么都没有得到。我的意思是什么都没有发生。

fileTransfer.download(url, this.file.dataDirectory + file.filename,false,{
        headers: {
            'authorization': 'bearer xxxx'
        }
    }).then((entry) => {
      console.log('download complete: ' + entry.toURL());
      console.log(entry.nativeURL);
      const browser = this.iab.create(entry.nativeURL, '_system', 'location=yes'); //here the inappbrowser plugin code.
    }, (error) => {
      // handle error
      console.log(error);
      console.log('ERROR');
    });

我的console.log(entry.nativeurl(;打印此路径file:///data/user/0/com.schneider.and/files/Attendance_Policy_Ver_1.0.pdf

Answer 1

尝试将本机url放在浏览器中，看看是否可以跳到确切的.pdf ....

然后尝试

fileTransfer.download(url, this.file.dataDirectory + file.filename,false,{
        headers: {
            'authorization': 'bearer xxxx'
        }
    }).then((entry) => {
      console.log('download complete: ' + entry.toURL());
      console.log(entry.nativeURL);
      let browser=new InApp Browser(entry.nativeURL,'_blank');
    }, (error) => {
      // handle error
      console.log(error);
      console.log('ERROR');
    });

和从'ionic-native'

导入Inappbrowser

import {InAppBrowser} from 'ionic-native';

我使用此代码及其作品

showDocument(){
      const options: DocumentViewerOptions = {
        title: 'My PDF'
      }
      const imgeLocation = `${cordova.file.applicationDirectory}www/assets/imgs/${'Jainbhajan-Jeevan-Saar-By-Nirmal-Gangwal-1-ilovepdf-compressed (1).pdf'}`;
      this.document.viewDocument(imgeLocation, 'application/pdf', options)
    }
