Detailed Description

Utility class for handling HTTP and network error status codes from XNAT requests.

QmitkHttpStatusCodeHandler is a non-instantiable utility class that parses error messages returned by CTK XNAT HTTP requests, extracts the status code, and displays an appropriate warning message box to the user. It handles a wide range of Qt network error codes (connection errors, proxy errors, content errors, protocol errors, and server errors) as well as standard HTTP error codes.

Note

This class cannot be instantiated. All functionality is accessed through the static HandleErrorMessage method.

Member Function Documentation

HandleErrorMessage()

static bool QmitkHttpStatusCodeHandler::HandleErrorMessage ( const char *  _errorMsg )

static

Parse an error message from an XNAT HTTP request and display a user-facing warning dialog.

Extracts the HTTP status code and server response from the error message string, then displays an appropriate QMessageBox warning. Consecutive duplicate error codes are suppressed to avoid flooding the user with repeated dialogs.

The expected error message format is:

ERROR: ... request failed. {uuid}: <code>: Error <url> - server replied: <message>

Parameters

[in]

_errorMsg

The raw error message string from the CTK XNAT runtime exception.

Returns

true if the error message was successfully parsed as an HTTP request failure, false otherwise. A general error dialog is shown for unparseable messages.
