问题描述

Android某些版本的手机不能够加载Https图片

解决方法

1. 使用Glide图片加载框架
2. 创建如下4个类

OkHttpStreamFetcher.java

public class OkHttpStreamFetcher implements DataFetcher<InputStream> {
    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.Entry<String, String> headerEntry : 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) {
            }
        }
        if (responseBody != null) {
            responseBody.close();
        }
    }

    @Override
    public String getId() {
        return url.getCacheKey();
    }

    @Override
    public void cancel() {
    }

}

OkHttpUrlLoader.java

public class OkHttpUrlLoader implements ModelLoader<GlideUrl, InputStream> {

    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 = new OkHttpClient();
                    }
                }
            }
            return internalClient;
        }

        public Factory() {
            this(getInternalClient());
        }

        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() {
        }
    }

    private final OkHttpClient client;

    public OkHttpUrlLoader(OkHttpClient client) {
        this.client = client;
    }

    @Override
    public DataFetcher<InputStream> getResourceFetcher(GlideUrl model, int width, int height) {
        return new OkHttpStreamFetcher(client, model);
    }
}

SSLSocketClient.java

public class SSLSocketClient {
    //获取这个SSLSocketFactory
    public static SSLSocketFactory getSSLSocketFactory() {
        try {
            SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, getTrustManager(), new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    //获取TrustManager
    private static TrustManager[] getTrustManager() {
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(X509Certificate[] chain, String authType) {
                    }

                    @Override
                    public void checkServerTrusted(X509Certificate[] chain, String authType) {
                    }

                    @Override
                    public X509Certificate[] getAcceptedIssuers() {
                        return new X509Certificate[]{};
                    }
                }
        };
        return trustAllCerts;
    }

    //获取HostnameVerifier
    public static HostnameVerifier getHostnameVerifier() {
        HostnameVerifier hostnameVerifier = new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        };
        return hostnameVerifier;
    }
}

GlideConfiguration.java

public class GlideConfiguration implements GlideModule {
    @Override
    public void applyOptions(Context context, GlideBuilder glideBuilder) {
        glideBuilder.setDecodeFormat(DecodeFormat.PREFER_ARGB_8888);
    }

    @Override
    public void registerComponents(Context context, Glide glide) {
        OkHttpClient build = new OkHttpClient().newBuilder()
                .sslSocketFactory(SSLSocketClient.getSSLSocketFactory())
                .hostnameVerifier(SSLSocketClient.getHostnameVerifier())
                .build();
        glide.register(GlideUrl.class, InputStream.class,new OkHttpUrlLoader.Factory(build));
    }
}

3. AndroidManifest配置

<meta-data
            android:name="com.common.sys.GlideConfiguration"//这里填自己类的路径
            android:value="GlideModule" />
