示例

1、配置超时

int timeout = 5;
RequestConfig config = RequestConfig.custom()
  .setConnectTimeout(timeout * 1000)
  .setConnectionRequestTimeout(timeout * 1000)
  .setSocketTimeout(timeout * 1000).build();
CloseableHttpClient client = HttpClientBuilder.create().setDefaultRequestConfig(config).build();

使用先前定义的客户端，与主机的连接将在5秒内超时，如果建立连接但没有收到数据，则超时也将是5秒。

请注意，连接超时将导致org.apache.http.conn.ConnectTimeoutException被抛出，而套接字超时将导致一个java.net.SocketTimeoutException。

2、Https请求

@Test
public void givenIgnoringCertificates_whenHttpsUrlIsConsumed_thenCorrect()
  throws Exception {
    SSLContext sslContext = new SSLContextBuilder()
      .loadTrustMaterial(null, (certificate, authType) -> true).build();
 
    CloseableHttpClient client = HttpClients.custom()
      .setSSLContext(sslContext)
      .setSSLHostnameVerifier(new NoopHostnameVerifier())
      .build();
    HttpGet httpGet = new HttpGet(HOST_WITH_SSL);
    httpGet.setHeader("Accept", "application/xml");
 
    HttpResponse response = client.execute(httpGet);
    assertThat(response.getStatusLine().getStatusCode(), equalTo(200));
}
