Glide图片加载不了，加载https图片解决
Glide加载网络图片，有些图片显示不出来。很大一部分的原因是https的不兼容。以下是我从CSDN上查找的这个问题的解决，分享给大家。
1、在build.gradle中添加依赖： compile'com.github.bumptech.glide:glide:3.6.1' compile'com.squareup.okhttp:okhttp:2.7.2' compile'com.github.bumptech.glide:okhttp-integration:1.4.0@aar'
2.拷贝'com.github.bumptech.glide:okhttp-integration:1.4.0@aar'里面3个类OkHttpGlideModule ，OkHttpUrlLoader，OkHttpStreamFetcher的源码；OkHttpGlideModule类：改写成如下忽略证书，支持https.
public class OkHttpGlideModule implements GlideModule {
@Override
public void applyOptions(Context context, GlideBuilder builder) {
// Do nothing.
}
@Override
public void registerComponents(Context context, Glide glide) {
OkHttpClient okHttpClient=new OkHttpClient();
X509TrustManager xtm = new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) {
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
X509Certificate[] x509Certificates = new X509Certificate[0];
return x509Certificates;
}
};
SSLContext sslContext = null;
try {
sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, new TrustManager[]{xtm}, new SecureRandom());
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
}
HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
okHttpClient.setSslSocketFactory(sslContext.getSocketFactory());
okHttpClient.setHostnameVerifier(DO_NOT_VERIFY);
glide.register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(okHttpClient));
}}
public class OkHttpStreamFetcher implements DataFetcher{ private final OkHttpClient client; private final GlideUrl url; private InputStream stream; private ResponseBody responseBody; public OkHttpStreamFetcher(OkHttpClient client, GlideUrl url) { this.client = client; this.url = url; } @Override public InputStream loadData(Priority priority) throws Exception { Request.Builder requestBuilder = new Request.Builder() .url(url.toStringUrl()); for (Map.EntryheaderEntry : url.getHeaders().entrySet()) {
String key = headerEntry.getKey();
requestBuilder.addHeader(key, headerEntry.getValue());
}
Request request = requestBuilder.build();
Response response = client.newCall(request).execute();
responseBody = response.body();
if (!response.isSuccessful()) {
throw new IOException("Request failed with code: " + response.code());
}
long contentLength = responseBody.contentLength();
stream = ContentLengthInputStream.obtain(responseBody.byteStream(), contentLength);
return stream;
}
@Override
public void cleanup() {
if (stream != null) {
try {
stream.close();
} catch (IOException e) {
// Ignored
}
}
if (responseBody != null) {
try {
responseBody.close();
} catch (IOException e) {
// Ignored.}}}
@Override
public String getId() {
return url.getCacheKey();
}
@Override
public void cancel() {
// TODO: call cancel on the client when this method is called on a background thread. See #257}}
public class OkHttpUrlLoader implements ModelLoader{ /** * The default factory for {@link OkHttpUrlLoader}s. */ public static class Factory implements ModelLoaderFactory{ private static volatile OkHttpClient internalClient; private OkHttpClient client; private static OkHttpClient getInternalClient() { if (internalClient == null) { synchronized (Factory.class) { if (internalClient == null) { internalClient = new OkHttpClient(); } } } 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 ModelLoaderbuild(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; } @Override public DataFetchergetResourceFetcher(GlideUrl model, int width, int height) {
return new OkHttpStreamFetcher(client, model);}}
3、删除在build.gradle中依赖：
compile'com.github.bumptech.glide:okhttp-integration:1.4.0@aar'；
4、在Android.Manifest中配置：
android:name="***.OkHttpGlideModule" android:value="GlideModule"/> 此时，重新运行后发现可以加载https啦。 但是，在发布后会出现找不到OkHttpGlideModule类。是因为被混淆了，因此发布时还得注意下
