解决httpclient访问ssl资源报证书错误的问题

创建一个自定义httpclient

public static HttpClient getHttpsClient() {
        HttpClient httpClient = null;
        SSLContext context;
        try {
            context = SSLContext.getInstance("SSL");
            context.init(null, new TrustManager[] {new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] paramArrayOfX509Certificate, String paramString)
                        throws CertificateException {
                }

                @Override
                public void checkServerTrusted(X509Certificate[] paramArrayOfX509Certificate, String paramString)
                        throws CertificateException {
                }

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }

            }}, new SecureRandom());

            HostnameVerifier verifier = new HostnameVerifier() {
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            };
            SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(context, verifier);
            httpClient = HttpClients.custom().setSSLSocketFactory(sslConnectionSocketFactory).build();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return httpClient;
    }

访问https资源

HttpClient httpClient = Tool.getHttpsClient();
String url = "https://pic2.zhimg.com/6f7c6805962dc58cc21d4df748f18125_xl.jpg";
HttpGet request = new HttpGet(url);
HttpResponse response = httpClient.execute(request);
