android – Glide – adding header to request-ThrowExceptions

Exception or error:

is there a method to add custom header to request when image is downloaded?
I can use volley or okhttp in Glide.

I try add cookie to cookiemanager in okhttpclient, but it doesn’t helped.
Is there a method to debug request response in Glide?

Best regards
Tom

How to solve:

Since 3.6.0 it’s possible to set custom headers for each request:

GlideUrl glideUrl = new GlideUrl("url", new LazyHeaders.Builder()
    .addHeader("key1", "value")
    .addHeader("key2", new LazyHeaderFactory() {
        @Override
        public String buildHeader() {
            String expensiveAuthHeader = computeExpensiveAuthHeader();
            return expensiveAuthHeader;
        }
    })
    .build());

Glide....load(glideUrl)....;

If you can’t get Glide to do it, you can use OkHttp Interceptors.

###

Try this:

ImageView imgThumb = itemView.findViewById(R.id.image_thumb);

GlideUrl url = new GlideUrl("https://your-url.com", new LazyHeaders.Builder()
                .addHeader("User-Agent", "your-user-agent")
                .build());

RequestOptions options = new RequestOptions()
    .diskCacheStrategy(DiskCacheStrategy.NONE);

Glide.with(mContext).load(glideUrl)
                    .transition(withCrossFade())
                    .thumbnail(0.5f)
                    .apply(options)
                    .into(imgThumb);

The Glide reference is:

implementation 'com.github.bumptech.glide:glide:4.6.1'

###

Kotlin + Glide 4.10.0

val token = "..."
val url = https://url.to.your.image
val glideUrl = GlideUrl(url) { mapOf(Pair("Authorization", "Bearer $token")) }

Glide.with(context)
     .load(glideUrl)
     .into(imageView)

###

Interceptors sound like a great choice. You can pass in your own instance of an OkHttp client to an OkHttpUrlLoader.Factory and register the Factory with Glide.

If you want more control, you can also simply fork the OkHttp ModelLoader and DataFetcher, register your forked ModelLoader, and get direct access to the OkHttp client for every request.

###

// make sure it's registered in AndroidManifest.xml as described at https://github.com/bumptech/glide/wiki/Configuration#including-a-glidemodule
public class GlideSetup implements GlideModule {
@Override public void applyOptions(Context context, GlideBuilder builder) { /* no costumization */ }
@Override public void registerComponents(Context context, Glide glide) {
    glide.register(String.class, InputStream.class, new HeaderedLoader.Factory());
}

private static class HeaderedLoader extends BaseGlideUrlLoader<String> {
    public static final Headers HEADERS = new LazyHeaders.Builder()
            .addHeader("User-Agent", USER_AGENT)
            .addHeader("App-Agent", APP_AGENT)
            .build();

    public HeaderedLoader(Context context) {
        super(context);
    }

    @Override protected String getUrl(String model, int width, int height) {
        return model;
    }

    @Override protected Headers getHeaders(String model, int width, int height) {
        return HEADERS;
    }

    public static class Factory implements ModelLoaderFactory<String, InputStream> {
        @Override public StreamModelLoader<String> build(Context context, GenericLoaderFactory factories) {
            return new HeaderedLoader(context);
        }
        @Override public void teardown() { /* nothing to free */ }
    }
}

}

and then

....load("http://....")....;

Please read this thread: https://github.com/bumptech/glide/issues/198

It appears as if it will be implemented in the coming release (4.0).

This is late, I think but I put it here for notes for anyone else facing the issue. Here are my code samples (this is for Glide v4):

BaseGlideUrlLoader module:

private static class HeaderedLoader extends BaseGlideUrlLoader<String> {

    public static final Headers HEADERS = new LazyHeaders.Builder()
            .addHeader("Referer", UserSingleton.getInstance().getBaseUrl())
            .build();

    public HeaderedLoader(ModelLoader<GlideUrl, InputStream> concreteLoader) {
        super(concreteLoader);
    }

    @Override public boolean handles(@NonNull String model) {
        return true;
    }

    @Override protected String getUrl(String model, int width, int height, Options options) {
        return model;
    }

    @Override protected Headers getHeaders(String model, int width, int height, Options options) {
        return HEADERS;
    }

    public static class Factory implements ModelLoaderFactory<String, InputStream> {

        @Override public @NonNull ModelLoader<String, InputStream> build(
                @NonNull MultiModelLoaderFactory multiFactory) {
            return new HeaderedLoader(multiFactory.build(GlideUrl.class, InputStream.class));
        }

        @Override public void teardown() { /* nothing to free */ }
    }
}

Add the HeaderLoader class in the AppGlideModule.

@Override
public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
    super.registerComponents(context, glide, registry);

    registry.replace(GlideUrl.class, InputStream.class,
            new OkHttpUrlLoader.Factory(CustomOkHttpsClient.getTrustedOkHttpClient()
            ));

    // override default loader with one that attaches headers
    registry.replace(String.class, InputStream.class, new HeaderedLoader.Factory());
}
