true).build();// Set the custom SSLContext for MinioClientreturn MinioClient.builder().endpoint(properties.getEndpoint()).credentials(properties.getAccessKey(), properties.getSecretKey()).httpClient(customHttpClient).build();}} 在上面的代码中我们创建了一个SSLContext其中的X509TrustManager会信任所有证书无论其是否由信任的证书颁发机构CA签署。创建了一个自定义的OkHttpClient该客户端信任所有证书。然后我们使用MinioClient.builder()方法将自定义的OkHttpClient传递给httpClient()方法 这种方法会将所有证书都视为受信任的因此请仅在非生产环境中使用此方法以确保通信的安全性和完整性。在生产环境中建议使用受信任的SSL证书。 3.2.2.1 拓展: 补充minioclient请求日志 之前minioclient与服务器端交互使用默认的httpclient的客户端,请求没有打印详细日志. 既然上面自定义自己的httpclient那么可以补充自定义拦截器打印日志 public class CustomLoggingInterceptor implements Interceptor {Overridepublic Response intercept(Chain chain) throws IOException {Request request chain.request();long startTime System.nanoTime();System.out.println(Sending request request.url() on chain.connection() \n request.headers());Response response chain.proceed(request);long endTime System.nanoTime();System.out.println(Received response for response.request().url() in ((endTime - startTime) / 1e6) ms\n response.headers());MediaType contentType response.body().contentType();String content response.body().string();System.out.println(Response body:\n content);ResponseBody wrappedBody ResponseBody.create(contentType, content);return response.newBuilder().body(wrappedBody).build();} }修改MinioConfig增加okhttp拦截器 // Create a custom OkHttpClient that trusts all certificatesOkHttpClient customHttpClient new OkHttpClient.Builder().sslSocketFactory(sslContext.getSocketFactory(), (X509TrustManager) trustAllCerts[0]).hostnameVerifier((hostname, session) - true).addInterceptor(new CustomLoggingInterceptor()) // Add custom interceptor here.build();效果 4. 问题总结 minio客户端本质使用httpclient与服务端交互,因此证书问题处理其实只是httpclient对证书的兼容处理。该处理方式可以运用到其他使用到httpclient的场景。 5.附录 代码优化 Configuration EnableConfigurationProperties(MinioProperties.class) public class MinioConfig {private static final Logger LOGGER LoggerFactory.getLogger(MinioConfig.class);Beanpublic MinioClient minioClient(MinioProperties properties){properties.check();OkHttpClient customHttpClient null;if (properties.getEndpoint().startsWith(https://)) {// 如果是HTTPS使用自定义的OkHttpClient处理自签名的HTTPS请求customHttpClient createCustomOkHttpClient();}MinioClient minioClient;if (customHttpClient ! null) {// 如果使用了自定义的OkHttpClientminioClient MinioClient.builder().endpoint(properties.getEndpoint()).credentials(properties.getAccessKey(), properties.getSecretKey()).httpClient(customHttpClient).build();} else {// 如果是普通HTTP使用默认的OkHttpClientminioClient MinioClient.builder().endpoint(properties.getEndpoint()).credentials(properties.getAccessKey(), properties.getSecretKey()).build();}return minioClient;}/*** Set the custom SSLContext for MinioClient* return*/private static OkHttpClient createCustomOkHttpClient() {// 创建自定义的OkHttpClient用于处理自签名的HTTPS请求// Create a trust manager that does not validate certificate chainsTrustManager[] trustAllCerts new TrustManager[] {new X509TrustManager() {public X509Certificate[] getAcceptedIssuers() {return new X509Certificate[0];}public void checkClientTrusted(X509Certificate[] certs, String authType) {// Do nothing (trust any client certificate)}public void checkServerTrusted(X509Certificate[] certs, String authType) {// Do nothing (trust any server certificate)}}};// Install the all-trusting trust managerSSLContext sslContext null;try {sslContext SSLContext.getInstance(SSL);sslContext.init(null, trustAllCerts, new java.security.SecureRandom());} catch (Exception e) {LOGGER.error(Install the all-trusting trust manager error:{}, e.getMessage());}// Create a custom OkHttpClient that trusts all certificatesOkHttpClient customHttpClient new OkHttpClient.Builder().sslSocketFactory(sslContext.getSocketFactory(), (X509TrustManager) trustAllCerts[0]).hostnameVerifier((hostname, session) -
