在使用Glide加载网络图片时，遇到Https的地址会加载不出来，是因为需要SSL验证，忽略掉SSL验证方法如下。

1、在gradle中增加okhttps依赖库

implementation("com.github.bumptech.glide:okhttp3-integration:4.0.0" ) {
           exclude group: "com.android.support"    }

2、定义一个类继承AppGlideModule类，并且使用@GlideModule注解

@GlideModulepublic class OkHttpAppGlideModule extends AppGlideModule{
       @Override    public void applyOptions(@NonNull Context context, @NonNull GlideBuilder builder) {
           super.applyOptions(context, builder);        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);    }    @Override    public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
           super.registerComponents(context, glide, registry);        //设置请求方式为okhttp 并设置okhttpClient的证书及超时时间        OkHttpUrlLoader.Factory factory = new OkHttpUrlLoader.Factory(UnsafeOkHttpClient.getUnsafeOkHttpClient());        registry.replace(GlideUrl.class, InputStream.class,factory);    }}

3、忽略SSL证书验证

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);        }    }}
