带毕加索的SSL证书固定 [英] SSL Certificate Pinning w/ Picasso

问题描述

我正在使用Picasso缓存图像.我们的后端最近使用自签名证书固定作为身份验证切换到HTTPS.我使用khandroid库创建了一个HTTP客户端，该客户端将证书固定到每个请求.基本上遵循这个例子.

I am using Picasso to cache Images. Our backend recently switched to HTTPS using self signed certificate pinning as authentication. I used the khandroid library to create an HTTP client that pins the certificates to each request; basically following this example.

我现在需要将同样的概念应用于Picasso，但是不确定如何修改Picasso的单例以使用固定的SSL证书.

I now need to apply this same concept to Picasso but am unsure how to modify Picasso's singleton to use pinned SSL certificates.

推荐答案

原来我只是在错误的地方看.我试图修改OkHttpDownloader，但是我需要修改OkHttpClient.这是一些示例代码.

Turns out I was Just looking in the wrong place. I was attempting to modify the OkHttpDownloader, but I needed to modify the OkHttpClient. Here is some sample code.

public static Picasso getInstance(Context context) {
        if (sPicasso == null) {
            InputStream keyStore = context.getResources().openRawResource(R.raw.my_keystore);
            Picasso.Builder builder = new Picasso.Builder(context);
            OkHttpClient okHttpClient = new OkHttpClient();
            SSLContext sslContext;
            try {
                sslContext = SSLContext.getInstance("TLS");
                sslContext.init(null, new TrustManager[]{new SsX509TrustManager(keyStore, password)}, null);
                okHttpClient.setSslSocketFactory(sslContext.getSocketFactory());
                OkHttpDownloader okHttpDownloader = new OkHttpDownloader(okHttpClient);
                builder.downloader(okHttpDownloader);
                sPicasso = builder.build();
            } catch (NoSuchAlgorithmException e) {
                throw new IllegalStateException("Failure initializing default SSL context", e);
            } catch (KeyManagementException e) {
                throw new IllegalStateException("Failure initializing default SSL context", e);
            } catch (GeneralSecurityException e) {
                e.printStackTrace();
            }
        }

        return sPicasso;
    }
