Question

是否有一种方法可以在下载图像时添加自定义标头以进行请求？我可以在Glide中使用volley或okhttp。

我尝试在okhttpclient中向cookiemanager添加cookie，但它没有帮助。有没有一种方法可以在Glide中调试请求响应？

祝你好运汤姆

Answer 1

由于3.6.0可以为每个请求设置自定义标头：

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)....;

如果你不能让Glide这样做，你可以使用OkHttp Interceptors。

Answer 3

尝试一下：

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);

滑行参考是：

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

Answer 4

拦截器听起来是个不错的选择。您可以将自己的OkHttp客户端实例传递给OkHttpUrlLoader.Factory和register Factory with Glide。

如果你想要更多控制，你也可以简单地分叉OkHttp ModelLoader和DataFetcher，注册你的分叉ModelLoader，并为每个请求直接访问OkHttp客户端。

我认为这已经很晚了，但是我将其放在此处以供其他面临此问题的人参考。这是我的代码示例（这是针对Glide v4的）：

BaseGlideUrlLoader模块：

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 */ }
    }
}

在AppGlideModule中添加HeaderLoader类。

@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());
}

请阅读此主题：https://github.com/bumptech/glide/issues/198

好像它将在即将发布的版本（4.0）中实现。

Answer 7

// 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 */ }
    }
}

}

然后

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

Answer 8

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)
