问题描述
我正在使用从Amazon S3加载图像的Android应用程序.图片网址会随令牌和有效期密钥的变化而随机变化.因此,我无法缓存图像Glide.
I am working in Android app that load images from Amazon S3.The Image URL randomly changes with token and expiry key. For that reason i can't cache the image Glide.
有任何方法可以将Glide缓存键设置为任何静态ID(例如图片ID)而不是网址.
There is any way to set Glide cache key as any static ID(like image id) not url.
我附加了我的代码段以从AWS加载图像
I attached my code snippet to load image from AWS
Glide.with(remoteGalleryAct).load(photoFinalImageURL)
.signature(new StringSignature(getImageUrl(photoFinalImageURL)))// remove AWS keys
.error(defaultNoImageDrawable)
.placeholder(defaultNoImageDrawable)
.dontAnimate()
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(new ImageViewTarget<GlideDrawable>(photoHolder.photo) {
@Override
protected void setResource(GlideDrawable resource) {
}
@Override
public void onResourceReady(final GlideDrawable resource, GlideAnimation<? super GlideDrawable> glideAnimation) {
//super.onResourceReady(resource, glideAnimation);
view.setImageDrawable(resource);
}
});
请建议我在Glide中有什么方法可以实现.
Please suggest me there is any way to achieve in Glide.
推荐答案
重写GlideUrl类的getCacheKey()方法.此方法设置用于缓存图像的密钥.
Override getCacheKey() method of GlideUrl class. This method sets the key for caching the image.
方法如下:
//Create a custom class and override the method to remove authentication header from the S3 image url
public class GlideUrlCustomCacheKey extends GlideUrl {
public GlideUrlCustomCacheKey(String url) {
super(url);
}
public GlideUrlCustomCacheKey(String url, Headers headers) {
super(url, headers);
}
public GlideUrlCustomCacheKey(URL url) {
super(url);
}
public GlideUrlCustomCacheKey(URL url, Headers headers) {
super(url, headers);
}
@Override
public String getCacheKey() {
String url = toStringUrl();
if (url.contains("?")) {
return url.substring(0, url.lastIndexOf("?"));
} else {
return url;
}
}
}
使用从此类获取的URL设置imageView:
Set the imageView with the URL obtained from this class:
Glide.with(context).load(new GlideUrlCustomCacheKey(buzzUrl)).into(imageView);
