Set the HttpConnection State when close request InputStream manually

[nespjin]

Fixed: Close request InputStream manually if not read request InputStream to end, then send response will throw java.lang.AssertionError

The Issue Sample:

        InputStream byteArrayInputStream = null;
        FileOutputStream fileOutputStream = null;
        try {
            byteArrayInputStream = mHttpExchange.getRequestBody();
            fileOutputStream = new FileOutputStream(fileDownload);
            byte[] buffer = new byte[LocalNetConfig.BUFFER_SIZE];

            while ((size = byteArrayInputStream.read(buffer)) > 0 && !isCanceled) {
                fileOutputStream.write(buffer, 0, size);
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {

                if (byteArrayInputStream != null) {
                    byteArrayInputStream.close();
                }

                if (fileOutputStream != null) {
                    fileOutputStream.close();
                }
            } catch (Exception ignore) {

            }

           // =================================================================
           // If isCanceled = true, the code of below will throw java.lang.AssertionError
          // =================================================================
           final OutputStream responseBody = mHttpExchange.getResponseBody();
            mHttpExchange.sendResponseHeaders(HttpStatusCode.OK, 0);

            String responseBodyString = "";
            final byte[] responseBodyStringBytes = responseBodyString.getBytes(StandardCharsets.UTF_8);
            responseBody.write(responseBodyStringBytes, 0, responseBodyStringBytes.length);
            responseBody.flush();
            responseBody.close();
        }
    }
