检测传出 HTTP 调用

用户工厂类显示应用程序如何使用适用于 Java 的 X-Ray 开发工具包的 HTTPClientBuilder 版本来检测传出 HTTP 调用。

例 src/main/java/scorekeep/UserFactory.java - HTTPClient 检测
import com.amazonaws.xray.proxies.apache.http.HttpClientBuilder;

  public String randomName() throws IOException {
    CloseableHttpClient httpclient = HttpClientBuilder.create().build();
    HttpGet httpGet = new HttpGet("http://uinames.com/api/");
    CloseableHttpResponse response = httpclient.execute(httpGet);
    try {
      HttpEntity entity = response.getEntity();
      InputStream inputStream = entity.getContent();
      ObjectMapper mapper = new ObjectMapper();
      Map<String, String> jsonMap = mapper.readValue(inputStream, Map.class);
      String name = jsonMap.get("name");
      EntityUtils.consume(entity);
      return name;
    } finally {
      response.close();
    }
  }

如果您当前使用 org.apache.http.impl.client.HttpClientBuilder，则只需使用 com.amazonaws.xray.proxies.apache.http.HttpClientBuilder 的语句换出该类的导出语句。
