ImageLoader和Glide加载Https的图片

原文地址：https://www.jianshu.com/p/56ccdc43cf6d

本文介绍的是如何在项目中加载以Https为开头的图片，图片加载框架是Glide和UIL,当加载图片时候禁用掉所有的 SSL 证书检查。

一、UIL加载图片

ImageLoader我们需要自己写一个图片加载替换掉原有的imageDownloader,在application中配置就可以了

1. 在Application中初始化ImageLoader

public class MyApplication extends Application {

    @Override
    public void onCreate()
    {
        super.onCreate();
        //设置OKHttp 支持https请求
        OkHttpUtils.getInstance().setCertificates();

        initImageLoader();
    }

    private void initImageLoader()
    {
        ImageLoaderConfiguration config = new ImageLoaderConfiguration
                .Builder(getApplicationContext())
                .threadPriority(Thread.NORM_PRIORITY - 2)
                .denyCacheImageMultipleSizesInMemory()
                .diskCacheFileNameGenerator(new Md5FileNameGenerator())
                //替换允许Https的图片加载
                .imageDownloader(new AuthImageDownloader(this))
                .tasksProcessingOrder(QueueProcessingType.LIFO).build();
        ImageLoader.getInstance().init(config);
    } 
}

2. AuthImageDownloader代码

import com.nostra13.universalimageloader.core.download.BaseImageDownloader;

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocketFactory;

/**
 * HTTPS的图片加载
 */
public class AuthImageDownloader extends BaseImageDownloader {

    private SSLSocketFactory mSSLSocketFactory;
    public AuthImageDownloader(Context context) {
        super(context);
        SSLContext sslContext = sslContextForTrustedCertificates();
        mSSLSocketFactory = sslContext.getSocketFactory();
    }
    public AuthImageDownloader(Context context, int connectTimeout, int readTimeout) {
        super(context, connectTimeout, readTimeout);
        SSLContext sslContext = sslContextForTrustedCertificates();
        mSSLSocketFactory = sslContext.getSocketFactory();
    }
    @Override
    protected InputStream getStreamFromNetwork(String imageUri, Object extra) throws IOException
    {
        URL url = null;
        try {
            url = new URL(imageUri);
        } catch (MalformedURLException e) {
        }
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setConnectTimeout(connectTimeout);
        conn.setReadTimeout(readTimeout);

        if (conn instanceof HttpsURLConnection) {
            ((HttpsURLConnection)conn).setSSLSocketFactory(mSSLSocketFactory);
            ((HttpsURLConnection)conn).setHostnameVerifier((DO_NOT_VERIFY));
        }
        return new BufferedInputStream(conn.getInputStream(), BUFFER_SIZE);
    }
    // always verify the host - dont check for certificate
    final HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    public SSLContext sslContextForTrustedCertificates() {
        javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[1];
        javax.net.ssl.TrustManager tm = new miTM();
        trustAllCerts[0] = tm;
        SSLContext sc = null;
        try {
            sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCerts, null);
            //javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }catch (KeyManagementException e) {
            e.printStackTrace();
        }finally {
            return sc;
        }
    }

    class miTM implements javax.net.ssl.TrustManager, javax.net.ssl.X509TrustManager {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }
        public boolean isServerTrusted(
                java.security.cert.X509Certificate[] certs) {
            return true;
        }
        public boolean isClientTrusted(
                java.security.cert.X509Certificate[] certs) {
            return true;
        }
        public void checkServerTrusted(
                java.security.cert.X509Certificate[] certs, String authType)
                throws java.security.cert.CertificateException {
            return;
        }
        public void checkClientTrusted(
                java.security.cert.X509Certificate[] certs, String authType)
                throws java.security.cert.CertificateException {
            return;
        }
    }
}

二、Glide加载图片

Glide加载Https需要自定义Module,并且要整合Okhttp,让okhttp禁用掉所有的 SSL 证书检查。

1. gradle引用

引用中介绍的比较麻烦,Glide已经提供了Module给我们使用。

compile 'com.squareup.okhttp3:okhttp:3.3.1'
compile 'com.github.bumptech.glide:glide:3.7.0'
/*提供的Module*/
compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar'

2. application中初始化

//让Glide能用HTTPS
Glide.get(this).register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(RetrofitUtils.getOkHttpClient()));

3. 设置证书
   这个不是必须的,当你没有证书的时候,就不需要获取,如果有就拿到InputStream,传到下面的getOkHttpClient()的方法中

try {
   InputStream input = getAssets().open("server.cer");
} catch (IOException e) {
   e.printStackTrace();
}

4. 配置OkHttp允许Https

   获取OkHttpClien

public class RetrofitUtils{    /**
     * 获取OkHttpClient
     * 设置允许HTTPS
     * */
    public static OkHttpClient getOkHttpClient(InputStream... certificates)
    {
        SSLSocketFactory sslSocketFactory = HttpsUtils.getSslSocketFactory(certificates, null, null);
        OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
        builder = builder.sslSocketFactory(sslSocketFactory);
        builder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session)
            {
                return true;
            }
    });
    return builder.build();
}

HttpsUtils中可以传递证书进入,如果没有证书就传null

import java.io.IOException;
import java.io.InputStream;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.CertificateFactory;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.KeyManager;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509TrustManager;

/**

public class HttpsUtils{
    public static SSLSocketFactory getSslSocketFactory(InputStream[] certificates, InputStream bksFile, String password){
        try{

            KeyManager[] keyManagers = prepareKeyManager(bksFile, password);
            SSLContext sslContext = SSLContext.getInstance("TLS");
            TrustManager trustManager = null;
            if (trustManagers != null){
                trustManager = new MyTrustManager(chooseTrustManager(trustManagers));
            } else{
                trustManager = new UnSafeTrustManager();
            }
            sslContext.init(keyManagers, new TrustManager[]{trustManager}, new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (NoSuchAlgorithmException e){
            throw new AssertionError(e);
        } catch (KeyManagementException e){
            throw new AssertionError(e);

    }

    }

    private static KeyManager[] prepareKeyManager(InputStream bksFile, String password){

所有代码引入后就可以,Glide就可以加载Https开头的图片了。
