我浪费了 6 天（并且还在增加）努力使用 ionic3-cordova 在 Android 上显示图库中的图像
this.fileChooser.open()
.then((uri) => {
console.log('image uri is', uri);
})
我不能使用uri直接绑定到我的标签的src
我尝试使用另一个插件并获取文件条目
return this.file.resolveLocalFilesystemUrl(uri);
我也不能使用它...不安全的uri！
然后我用了this.domSanitizer.bypassSecurityTrustUrl(entry.toInternalURL());
我不能用它来绑定到 img src
我不明白获取 uri、转换为另一个以确保安全，然后再次转换为另一个以提高安全性的意义...但仍然无法达到目的...
除了挫折之外，请帮助我如何在这个不断变化的角度科尔多瓦离子世界中将html img标签的src绑定到从图库中选择的图像..一个学期前回答的文档/问题已经过时了角度6
我在index.html 的内容安全策略标记中添加了 cdvfile:
我像这样在 html 中绑定 img 标签
<img class="profile-img" [src]="imageSrc" />
尿布更改条目的内部 url 并将其绑定到 img src 后得到的最终错误是
GET cdvfile://localhost/content/com.android.providers.media.documents/document/image%3A4350:1 GET cdvfile://localhost/content/com.android.providers.media.documents/document/image%3A4350 0 ()
