HttpClient代碼設置代理

由於對接faceBook接口，本地測試時候要設置代理才能調試。

（http和https通用）

public  SSLContext createIgnoreVerifySSL() throws NoSuchAlgorithmException, KeyManagementException {
        SSLContext sc = SSLContext.getInstance("SSLv3");

        // 實現一個X509TrustManager接口，用於繞過驗證，不用修改里面的方法
        X509TrustManager trustManager = new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    java.security.cert.X509Certificate[] paramArrayOfX509Certificate,
                    String paramString) throws CertificateException {
            }

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

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sc.init(null, new TrustManager[]{trustManager}, null);
        return sc;
    }

    public static HttpClientBuilder proxy(String hostOrIP, int port){
        // 依次是代理地址，代理端口號，協議類型
        HttpHost proxy = new HttpHost(hostOrIP, port, "http");
        DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
        return HttpClients.custom().setRoutePlanner(routePlanner);
    }

SSLContext sslcontext = null;
try {
    sslcontext = createIgnoreVerifySSL();
} catch (NoSuchAlgorithmException e) {
    e.printStackTrace();
} catch (KeyManagementException e) {
    e.printStackTrace();
}

// 設置協議http和https對應的處理socket鏈接工廠的對象
       Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
         .register("http", PlainConnectionSocketFactory.INSTANCE)
         .register("https", new SSLConnectionSocketFactory(sslcontext))
         .build();
          PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager(socketFactoryRegistry);
          HttpClients.custom().setConnectionManager(connManager);
 //創建自定義的httpclient對象，代理地址和端口
        CloseableHttpClient httpClient = proxy("127.0.0.1", 2222).setConnectionManager(connManager).build();
