一、引入库文件

implementation 'com.github.bumptech.glide:glide:4.5.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.5.0'
//https图片处理
implementation "com.github.bumptech.glide:okhttp3-integration:4.5.0"

二、重写AppGlideModule

/**
 * Created by wangfengkai on 2019/2/18.
 */
@GlideModule
public class OkHttpAppGlideModule  extends AppGlideModule {

@Override
public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
    OkHttpClient client = UnsafeOkHttpClient.getUnsafeOkHttpClient();
    registry.replace(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(client));
}
}

必须加上 @GlideModule注解，其中UnsafeOkHttpClient类的代码如下：

public class UnsafeOkHttpClient {
public static OkHttpClient getUnsafeOkHttpClient() {
    try {
        // Create a trust manager that does not validate certificate chains
        final TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                    }

                    @Override
                    public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                    }

                    @Override
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return new java.security.cert.X509Certificate[]{};
                    }
                }
        };

        // Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new java.security.SecureRandom());

        // Create an ssl socket factory with our all-trusting manager
        final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        builder.sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0]);
        builder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

        builder.connectTimeout(20, TimeUnit.SECONDS);
        builder.readTimeout(20,TimeUnit.SECONDS);

        OkHttpClient okHttpClient = builder.build();
        return okHttpClient;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}
}

三、配置glide加载https所需要的GlideModule

    <meta-data
        android:name="xxx.xxx.xxx.OkHttpAppGlideModule"
        android:value="AppGlideModule"/>

四、混淆

-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep class com.bumptech.glide.GeneratedAppGlideModuleImpl { *; }
