Glide如何加载https图片（简明操作）

利用以下简明步骤可以快速完成Glide加载https图片
- gradle引用

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’

可在application中操作

1.设置证书传入

try {
    InputStream[] InputStream = new InputStream[1];
    InputStream input = getApplication().getAssets().open("CA_.cer");
    InputStream[0] = input;
} catch (IOException e) {
     e.printStackTrace();
}

2.初始化

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

3.创建HttpsUtils类

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;

import okhttp3.OkHttpClient;
