在ngSrc中使用相机插件中的FILE_URI [英] Use FILE_URI from camera plugin in ngSrc
问题描述
我使用 ionic-native
库来访问带有以下选项的相机插件:
I use ionic-native
library to access the camera plugin with the following options:
let options = {
quality:50,
destinationType:1,
sourceType:1,
allowEdit:false,
encodingType:1,
mediaType:0,
correctOrientation:true,
saveToPhotoAlbum:false,
cameraDirection:1
};
拍完照片后,我得到 FILE_URI
为 file:/// storage / emulated / 0 / Android / data / com.company.testApp / cache / 1461661383435.png
但是当我在<$ c $的 ngSrc
属性中使用它时c> img tag,它只显示一个空块。
在使用chrome检查时,对图像的请求状态为(阻止:其他)
After taking the picture, I get the FILE_URI
as file:///storage/emulated/0/Android/data/com.company.testApp/cache/1461661383435.png
But when I use it in the ngSrc
property of the img
tag, It just displays an empty block.
While inspecting with chrome, the request for the image has the status of (blocked:other)
此外,我不想使用 DATA_URL
,因为它会降低性能。
Also I don't want to use DATA_URL
, since it degrades the performance.

这篇文章。
在Android 4.4 +上允许访问本地文件资源是显而易见的。
It is EXPLICITLY needed to allow access to local file resource at Android 4.4+.
将以下行添加到 config.xml
:
< allow-navigation href =*/>
< allow-navigation href =file:// * / */>
并设置 Content-Security-Policy
in index.html
as
And also set the Content-Security-Policy
in index.html
as
< meta http-equiv =Content-Security-Policycontent =default-src *; style-src'self''unsafe-inline'; script-src'self''unsafe-inline ''unsafe-eval'>
使用实时重新加载时,这不起作用。
