      • getContent

        public java.io.InputStream getContent()
                               throws java.io.IOException
        Returns the HTTP response content input stream or null for none.

        Returns URLConnection.getInputStream() when it doesn't throw IOException, otherwise it returns HttpURLConnection.getErrorStream().

        Upgrade warning: in prior version 1.16 getContent() returned URLConnection.getInputStream() only when the status code was successful. Starting with version 1.17 it returns URLConnection.getInputStream() when it doesn't throw IOException, otherwise it returns HttpURLConnection.getErrorStream()

        Upgrade warning: in versions prior to 1.20 getContent() returned URLConnection.getInputStream() or HttpURLConnection.getErrorStream(), both of which silently returned -1 for read() calls when the connection got closed in the middle of receiving a response. This is highly likely a bug from JDK's HttpURLConnection. Since version 1.20, the bytes read off the wire will be checked and an IOException will be thrown if the response is not fully delivered when the connection is closed by server for whatever reason, e.g., server restarts. Note though that this is a best-effort check: when the response is chunk encoded, we have to rely on the underlying HTTP library to behave correctly.

      • getHeaderCount

        public int getHeaderCount()
        Description copied from class: LowLevelHttpResponse
        Returns the number of HTTP response headers.

        Note that multiple headers of the same name need to be supported, in which case each header value is treated as a separate header.
