Glide: How to add header to all requests?

Created on 25 May 2015 · 10Comments · Source: bumptech/glide

I know that HTTP headers can be added like this:

      GlideUrl url = new GlideUrl("http://....", new LazyHeaders.Builder()
            .addHeader("User-Agent", USER_AGENT)
            .addHeader("App-Agent", APP_AGENT)
            .build());
      ....load(url)....;

But how to do that Just one time for all requests?

Yup pretty much.

I'd recommend using a custom data model though, rather than String. If you register a BaseGlideUrlLoader<String> like the one you've written that only recognizes URLs, you replace Glide's default String loader that recognizes URLs, Uris, and file paths.

As an alternative you can register a new type (YourModel), register a BaseGlideUrlLoader<YourModel>, and then start loads with objects of that class (Glide.with(fragment).load(yourModel)). You can see the FlickrModelLoader or GiphyModelLoader for examples of this.

I would try this way (untested on device, but compiles):

// 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://....")....;

If you're not using load(String), but load(Uri) for example, I think you'll have to register a similar ModelLoader for that too. The idea should be the same for any model.

I guess if you want to combine the two (static and dynamic headers) you would need to change Strings above to GlideUrl and merge headers in getHeaders; or create your own factory for creating Headers which prepopulates a LazyHeaders.Builder for example.

@sjudd was this what you meant in 3.6.0 release notes?
