我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用werkzeug.debug.tbtools.get_current_traceback()。
def showtraceback(self): from werkzeug.debug.tbtools import get_current_traceback tb = get_current_traceback(skip=1) sys.stdout._write(tb.render_summary())
def showsyntaxerror(self, filename=None): from werkzeug.debug.tbtools import get_current_traceback tb = get_current_traceback(skip=4) sys.stdout._write(tb.render_summary())
def debug_application(self, environ, start_response): """Run the application and conserve the traceback frames.""" app_iter = None try: app_iter = self.app(environ, start_response) for item in app_iter: yield item if hasattr(app_iter, 'close'): app_iter.close() except Exception: if hasattr(app_iter, 'close'): app_iter.close() traceback = get_current_traceback(skip=1, show_hidden_frames= self.show_hidden_frames, ignore_system_exceptions=True) for frame in traceback.frames: self.frames[frame.id] = frame self.tracebacks[traceback.id] = traceback try: start_response('500 INTERNAL SERVER ERROR', [ ('Content-Type', 'text/html; charset=utf-8'), # Disable Chrome's XSS protection, the debug # output can cause false-positives. ('X-XSS-Protection', '0'), ]) except Exception: # if we end up here there has been output but an error # occurred. in that situation we can do nothing fancy any # more, better log something into the error log and fall # back gracefully. environ['wsgi.errors'].write( 'Debugging middleware caught exception in streamed ' 'response at a point where response headers were already ' 'sent.\n') else: yield traceback.render_full(evalex=self.evalex, secret=self.secret) \ .encode('utf-8', 'replace') traceback.log(environ['wsgi.errors'])
def render_exception(self): traceback = get_current_traceback() for frame in traceback.frames: self.debug_app.frames[frame.id] = frame self.debug_app.tracebacks[traceback.id] = traceback return traceback.render_full(evalex=True, secret=self.debug_app.secret)
