Default Http sender failed to parse http Entity into string

I got a `IoException` When I try to parse http Entity from a ASP.NET api into string.

Code:
  String responseBody = IOUtils.toString(httpResponse.getEntity().getContent(), responseCharset)
or
Code:
String responseBody =EntityUtils.toString((httpResponse.getEntity());

I try to do it by using these two method.They all works fine except the **ASP.NET api**,which can be requested normally with Postman.

I got the function which throw the exception when run at 'while' the second time.


Code:
 public static long copyLarge(InputStream input, OutputStream output, byte[] buffer)  throws IOException {
            long count = 0;
            int n = 0;
            while (EOF != (n = input.read(buffer))) {
                output.write(buffer, 0, n);
                count += n;
            }
            return count;
        }
The stack as follows:

**The second way also failed when try to read buffer from a EofSensorInputStream**

version:3.4.2 jdk:1.8.0_65
