当Fresco/Picasso遇到https（停止更新）

0、停止更新说明：

在新本版的Picasso和Fresco框架都已经支持了对https图片的加载。
导致这篇文章也失去了意义！感谢大家！

当Fresco/Picasso遇到https,原来的图片就加载不出来了。这个应该怎么搞？查了查，进行如下配置：

1、Fresco：

1.1.1如果你使用的是okhttp2: 在build.gradle中添加依赖：

dependencies {
 // your project's other dependencies 
compile "com.facebook.fresco:imagepipeline-okhttp:0.12.0+"
}

1.1.2如果你使用的是okhttp3:

在build.gradle中添加依赖：

dependencies {
 // your project's other dependencies 
compile "com.facebook.fresco:imagepipeline-okhttp3:0.12.0+"
}

1.2在application中初始化：

Context context;
OkHttpClient okHttpClient; 
// build on your ownImagePipelineConfig config = OkHttpImagePipelineConfigFactory .newBuilder(context, okHttpClient) .build();
Fresco.initialize(context, config);

导包信息如下：

import com.facebook.drawee.backends.pipeline.Fresco;
import com.facebook.imagepipeline.backends.okhttp3.OkHttpImagePipelineConfigFactory;
import com.facebook.imagepipeline.core.ImagePipelineConfig;

2、Picasso：

2.1这个配置比较简单：在application中初始化，添加如下代码：

 Picasso.setSingletonInstance(new Picasso.Builder(mContext). downloader(new OkHttpDownloader(getUnsafeOkHttpClient())) .build());

2.2添加如下方法：

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.setHostnameVerifier(new HostnameVerifier() { 
@Override 
public boolean verify(String hostname, SSLSession session) {
 return true; 
} 
});
 return okHttpClient; 
} catch (Exception e) { 
throw new RuntimeException(e);
 } 
}

2.3 但是此处注意：new OkHttpDownloader方法，在导包的时候一定要导入Picasso中的okhttp中的包，不要使用项目中用到的okhttp中的包，具体导入如下：

import com.squareup.picasso.OkHttpDownloader;
import com.squareup.picasso.Picasso;

好了，到这里就能使用Fresco和Picasso在https网络环境下加载图片了！赶紧去试试吧！
