java - OkHttp:与 http://example.com/的连接被泄露。您是否忘记关闭响应主体？

Question

OkHttp v3.4.1 的这个错误消息已经讨论过几次了，每次我读到它时，人们都没有关闭响应正文:

  WARNING: A connection to http://www.example.com/ was leaked. Did you forget to close a response body?

但是我的代码是这样的:

  private String executeRequest(Request request) throws IOException {
    Response response = httpClient.newCall(request).execute();

    try (ResponseBody responseBody = response.body()) {
      String string = responseBody.string();
      logger.debug("Result: {}", string);
      return string;
    }
  }

因此 responseBody.close() 总是被调用。 我为什么会收到上述错误？我配置了自定义 JWT 拦截器，但我不知道它如何导致问题:

public class JwtInterceptor implements Interceptor {

  private String jwt;

  @Override
  public Response intercept(Chain chain) throws IOException {
    Request request = chain.request();

    if (jwt != null) {
      request = request.newBuilder()
          .addHeader("Authorization", "Bearer " + jwt)
          .build();
    }

    Response response = chain.proceed(request);
    String jwt = response.header("jwt");
    if (jwt != null) {
      this.jwt = jwt;
    }

    return chain.proceed(request);
  }
}

Answer 1

原来我的拦截器被窃听了:

return chain.proceed(request);

应该是:

return response;
