OkHttp：与http://example.com/的连接泄露了。你忘记关闭一个响应机构了吗？

Question

OkHttp v3.4.1的这个错误信息已经讨论了几次，每次我读到它时，人们都没有关闭响应主体：

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

但我的代码如下：

  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;
    }
  }

所以responseBody.close()总是被称为。为什么我得到上述错误？我配置了一个自定义JWT拦截器，但我不知道它是如何导致问题的：

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

结果我的拦截器被窃听：

return chain.proceed(request);

应该：

return response;
