Question

我正在使用apache-components在本地托管我自己的服务器。我尝试向其发送GET请求，并且收到的响应是预期的。客户端代码的输出为：

                {
                   // dbCategory.Id = Guid.NewGuid();
                    // CategoryId = model.CategoryId,
                    dbCategory.VariantName = model.VariantName;
                    dbCategory.IsExists = model.IsExists != null;
                    dbCategory.CreatedDate = DateTime.Now;
                    dbCategory.CreatedBy = model.CreatedBy;
                    dbCategory.UpdatedDate = DateTime.Now;
                    dbCategory.UpdatedBy = model.UpdatedBy;
                };
                dbcontext.CarCategories.Add(dbCategory);
                dbcontext.SaveChanges();
            }
        }
        catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)
        {
            Exception raise = dbEx;
            foreach (var validationErrors in dbEx.EntityValidationErrors)
            {
                foreach (var validationError in validationErrors.ValidationErrors)
                {
                    string message = string.Format("{0}:{1}",
                        validationErrors.Entry.Entity.ToString(),
                        validationError.ErrorMessage);
                    // raise a new exception nesting  
                    // the current instance as InnerException  
                    raise = new InvalidOperationException(message, raise);
                }
            }
            throw raise;
        }

        return Id;

    }

但是，在服务器上，对于我的每个请求，我仍然在服务器日志中看到以下错误：

Sending 'GET' request to URL : http://localhost:65432/test
Response Code : 200
This is the response

我知道服务器实现是正确的，因为当我使用浏览器访问 http://localhost:65432/test 时，错误未出现在服务器日志中。

这是客户端调用GET的代码（从https://www.mkyong.com/java/how-to-send-http-request-getpost-in-java/复制）。

java.io.IOException: An existing connection was forcibly closed by the remote host

以防万一您需要它。这是我的服务器处理程序代码

String url = String.format("%s://%s%s", "http", "localhost:65432", "/test");

URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();

// optional default is GET
con.setRequestMethod("GET");

con.setRequestProperty("User-Agent", "Mozilla/5.0");

int responseCode = con.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);

BufferedReader in = new BufferedReader(
            new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();

while ((inputLine = in.readLine()) != null) {
    response.append(inputLine);
}
in.close();

//print result
System.out.println(response.toString());

如何正确关闭客户端代码中的连接，以使错误不会出现在服务器日志中？
