Question

您好我正在尝试连接服务，但在调用

时失败并显示以下错误

 CloseableHttpResponse response = httpclient.execute(httpget);
    data = IOUtils.toString(response.getEntity().getContent(),
                    StandardCharsets.UTF_8);

我没有回复。因此，我假设这不可能是因为在读取整个数据之前连接已关闭？我怎么能在我的代码中处理这个？如何在生产中处理？这是我的代码或服务的问题吗？

似乎实体内容无法流式传输，因为它已关闭。 Connection reset通常会告诉您GET请求/响应有问题。

但是，您可能还想查看此内容：

What's the recommended way to get the HTTP response as a String when using Apache's HTTP Client?

接受的答案显示了处理HTTP响应的好方法（使用EntityUtils和HttpResponse）。

与HTTP服务的连接失败
