# 检测传出 HTTP 调用
HTTP 客户端

**注意**  
X-Ray SDK/Daemon 维护通知 — 2026 年 2 月 25 日， Amazon X-Ray SDKs/Daemon 将进入维护模式，在该模式下，X-Ray SDK 和 Daemon 的发布 Amazon 将仅限于解决安全问题。有关支持时间表的更多信息，请参阅 [X-Ray SDK 和 Daemon Support 时间表](xray-sdk-daemon-timeline.md)。我们建议迁移到 OpenTelemetry。有关迁移到的更多信息 OpenTelemetry，请参阅[从 X-Ray 仪器迁移到 OpenTelemetry 仪器](https://docs.amazonaws.cn/xray/latest/devguide/xray-sdk-migration.html)。

用户工厂类显示应用程序如何使用 X-Ray SDK for Java 的 `HTTPClientBuilder` 版本来检测传出 HTTP 调用。

**Example [https://github.com/awslabs/eb-java-scorekeep/tree/xray/src/main/java/scorekeep/UserFactory.java](https://github.com/awslabs/eb-java-scorekeep/tree/xray/src/main/java/scorekeep/UserFactory.java)— HTTPClient 仪器**  

```
import [com.amazonaws.xray.proxies.apache.http.HttpClientBuilder](https://docs.amazonaws.cn/xray-sdk-for-java/latest/javadoc/com/amazonaws/xray/proxies/apache/http/HttpClientBuilder.html);

  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。
