android - 从android照片库复制图片会导致错误

Question

当我尝试通过 phonegap 解析本地文件系统 uri 时出现此错误:

java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaDocumentsProvider

我使用相机访问照片库并收到此 file_uri:

content://com.android.providers.media.documents/document/image%3A355

然后我尝试访问本地文件系统:

window.resolveLocalFileSystemURI(file_uri, function(a){console.log("success");}, function(b){console.log("fail");});

这就是我收到此错误的地方:

顺便说一句:我在 iOS 上试过这个场景，它没有问题。

Answer 1

这里有一个简单的解决方法:

替换这个:

content://com.android.providers.media.documents/document/image%3A352

通过这个:

content://com.android.providers.media.documents/document/image%253A352

如果您使用的是 JavaScript，则可以使用此代码:

var path = content://com.android.providers.media.documents/document/image%3A352;
path = path.replace("%", "%25");

此技术强制 uri 按原样传递“%3A”，而不将其更改为“:”，
