在Cordova InAppBrowser上打开createObjectURL Blob [英] Open createObjectURL Blob on Cordova InAppBrowser

问题描述

我有一个Angular2 +/Cordova应用程序，我正在提出API请求以获取PDF.我想在Web +本机环境中打开此PDF.

I have an Angular2+/Cordova app, and I'm making an API request to get a PDF. I'd like to open this PDF in Web + Native environments.

对于网络，我正在打开窗口，获取PDF&从中创建一个Blob，然后执行createObjectURL并将窗口的location.href设置为该URL.效果很好(在Chrome/FF上).

For web I'm opening the window, getting the PDF & creating a Blob from it, then doing createObjectURL and setting the window's location.href to that URL. It works well (on Chrome/FF).

在本机上，我想做类似的事情，但理想情况下，只需使用来自createObjectURL的URL进行window.open(通过InAppBrowser插件).这可能吗?我返回的URL类似于:blob:file:///ef76ad0d-7c7f-4817-915f-9097160d1a58.尝试通过具有_system目标的InAppBrowser打开此文件绝对不会执行任何操作.没有错误，没有窗口，什么也没有.想知道是否需要为此做特别的白名单或SCP事情?

On native I'd like to do something similar, but ideally just do a window.open (via the InAppBrowser plugin) with the URL that came from createObjectURL. Is this possible? The URL I get back is something like: blob:file:///ef76ad0d-7c7f-4817-915f-9097160d1a58. Trying to open this via InAppBrowser with a _system target does absolutely nothing. No errors, no windows, no nothing. Wondering if there are special whitelist or SCP things I need to do for this?

推荐答案

作为参考，我不喜欢这种解决方案，但是在这种情况下，我最终以不同的方式对待web和native.

For reference, I don't like this solution, but I ended up treating web and native differently in this case.

WEB: 打开窗口-> REST调用以获取Blob->带Blob的createObjectURL->将窗口位置href设置为上一步的结果

WEB: Open Window --> REST call to get Blob --> createObjectURL with Blob --> set window location href to result of previous step

本机: REST调用以获取Blob->使用Cordova File插件保存Blob->使用Cordova File Opener插件打开保存的文件

NATIVE: REST call to get Blob --> Save Blob with Cordova File plugin --> Open saved file with Cordova File Opener plugin
