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
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。
