Glide加载自签名认证的https图片

困扰了很多天的问题，网上也找了很多技术帖看，但很多都是零零散散，下面我就把我解决过程中遇到的问题点跟大家说一下。

一、添加依赖：

• compile ‘com.github.bumptech.glide:glide:3.7.0’
• compile ‘com.squareup.okhttp:okhttp:2.7.5’ //添加okhttp3会出现问题具体下面会说

二、重写需要的类：

1、

public class OkHttpGlideModule implements GlideModule {@Overridepublic void applyOptions(Context context, GlideBuilder builder) {    // Do nothing.}@Overridepublic void registerComponents(Context context, Glide glide) {    glide.register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory());}

2、

public class OkHttpUrlLoader implements ModelLoader<GlideUrl, InputStream> {/** * The default factory for {@link OkHttpUrlLoader}s. */public static class Factory implements ModelLoaderFactory<GlideUrl, InputStream> {    private static volatile OkHttpClient internalClient;    private                 OkHttpClient client;    private static OkHttpClient getInternalClient() {        if (internalClient == null) {            synchronized (Factory.class) {                if (internalClient == null) {                    internalClient = UnsafeOkHttpClient.getUnsafeOkHttpClient();                }            }        }        return internalClient;    }    /**     * Constructor for a new Factory that runs requests using a static singleton client.     */    public Factory() {        this(getInternalClient());    }    /**     * Constructor for a new Factory that runs requests using given client.     */    public Factory(OkHttpClient client) {        this.client = client;    }    @Override    public ModelLoader<GlideUrl, InputStream> build(Context context, GenericLoaderFactory factories) {        return new OkHttpUrlLoader(client);    }    @Override    public void teardown() {        // Do nothing, this instance doesn't own the client.    }}private final OkHttpClient client;public OkHttpUrlLoader(OkHttpClient client) {    this.client = client;}@Overridepublic DataFetcher<InputStream> getResourceFetcher(GlideUrl model, int width, int height) {    return new OkHttpStreamFetcher(client, model);}

3、

public class OkHttpUrlLoader implements ModelLoader<GlideUrl, InputStream> {/** * The default factory for {@link OkHttpUrlLoader}s. */public static class Factory implements ModelLoaderFactory<GlideUrl, InputStream> {    private static volatile OkHttpClient internalClient;    private                 OkHttpClient client;    private static OkHttpClient getInternalClient() {        if (internalClient == null) {            synchronized (Factory.class) {                if (internalClient == null) {                    internalClient = UnsafeOkHttpClient.getUnsafeOkHttpClient();                }            }        }        return internalClient;    }    /**     * Constructor for a new Factory that runs requests using a static singleton client.     */    public Factory() {        this(getInternalClient());    }    /**     * Constructor for a new Factory that runs requests using given client.     */    public Factory(OkHttpClient client) {        this.client = client;    }    @Override    public ModelLoader<GlideUrl, InputStream> build(Context context, GenericLoaderFactory factories) {        return new OkHttpUrlLoader(client);    }    @Override    public void teardown() {        // Do nothing, this instance doesn't own the client.    }}private final OkHttpClient client;public OkHttpUrlLoader(OkHttpClient client) {    this.client = client;}@Overridepublic DataFetcher<InputStream> getResourceFetcher(GlideUrl model, int width, int height) {    return new OkHttpStreamFetcher(client, model);}

• 这个类重要的代码是创建 internalClient 对象：internalClient = UnsafeOkHttpClient.getUnsafeOkHttpClient();。

4、

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 null;                    }                }        };        // 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 okHttpClient = new OkHttpClient();        okHttpClient.setSslSocketFactory(sslSocketFactory);        okHttpClient.setProtocols(Arrays.asList(Protocol.HTTP_1_1));        okHttpClient.setHostnameVerifier(new HostnameVerifier() {            @Override            public boolean verify(String hostname, SSLSession session) {                return true;            }        });        return okHttpClient;    } catch (Exception e) {        throw new RuntimeException(e);    }}

• 如果使用的okhttp3，调用okHttpClient.setSslSocketFactory(sslSocketFactory);这几个方法会报错
• 创建 OkHttpClient 禁用掉所有的 SSL 证书检查。

三、在AndroidManifest中配置

• Glide需要加载网络图片所以需要网络图片
• 配置我们刚刚写的OkHttpGlideModule
• meta-data
  android:name=”com.lee.glidetest.https.OkHttpGlideModule”
  android:value=”GlideModule”/>

四、现在你就使用Glide加载自签名的https图片啦

public void getHttpsImg(View view) {    String url = "https://travel.12306.cn/imgs/resources/uploadfiles/images/a9b9c76d-36ba-4e4a-8e02-9e6a1a991da0_news_W540_H300.jpg";    Glide.with(this)            .load(url)            .asBitmap()            .listener(new RequestListener<String, Bitmap>() {                @Override                public boolean onException(Exception e, String model, Target<Bitmap> target, boolean isFirstResource) {                    System.out.println("--------------Exception--------------" + e);                    return false;                }                @Override                public boolean onResourceReady(Bitmap resource, String model, Target<Bitmap> target, boolean isFromMemoryCache, boolean isFirstResource) {                    return false;                }            })            .into(imageView);}
