的setHeader（授权，承载+令牌）;

I am using Picasso library to load and download images from my server, but now I want to add a header in my download request and I cant seem to find a way of doing it. all i want to do is set a header like : setHeader("Authorization", "Bearer " + token);

I use this header in any of my server requests, but cant find a way to add it to the picasso line.

任何帮助将是AP preciated，谢谢！

Any help would be appreciated, Thanks!

推荐答案

毕加索使用 OkHttp 为发动机的，或者是可能的毕加索配置为使用它，因为你必须设置HTTP请求的头，你可以使用拦截。例如。这是我的拦截器来处理基本身份验证：

Picasso uses OkHttp as engine , or it is possible to configure Picasso to use it, and since you have to set the header of the http request, you can use an Interceptor. E.g. this is my Interceptor to handle basic authentication:

private static class BasicAuthInterceptor implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {
        final Request original = chain.request();
        final Request.Builder requestBuilder = original.newBuilder()
                .header("Authorization", "Basic " + BASIC_AUTH_ENCODED)
        .method(original.method(), original.body());
        return chain.proceed(requestBuilder.build());
    }
}

和你添加拦截器OkHttp像

and the you add the Interceptor to OkHttp like

 OkHttpClient okHttpClient = new OkHttpClient();
 okHttpClient.interceptors().add(new BasicAuthInterceptor());

最后一步是配置毕加索使用 okHttpClient 。
毕加索的建设者为它提供了一种方法：

Last step is to configure Picasso to use okHttpClient. The Picasso's builder provide a method for it :

new Picasso.Builder(context).downloader(new OkHttpDownloader(okHttpClient)).build();
