  • Download Har File Viewer
    download har file viewer Download har file viewer. Если вы не знаете, как получить HAR-файл, ознакомьтесь с инструкцией на странице загрузки для трех самых распространенных браузеров: Chrome, Firefox и Internet Explorer. Нажмите кнопку выбора файла. Выберите HAR-файл для анализа. Воспользуйтесь ей, чтобы выбрать файл для анализа. Записи могут быть показаны вместе или с разбивкой по страницам. Временные метки записей в таблице могут быть относительными или абсолютными. В первом режиме метки, которые соответствуют каждой записи, располагаются на временной шкале обработки страницы, а во втором метка каждой записи занимает всю ширину столбца. Относительный режим используется только при группировке записей по страницам. – полезный инструмент, позволяющий выполнять сложный поиск в HAR-записях. Самый простой способ поиска – ввести несколько поисковых слов, например [получить диск]. В результате будут найдены записи, содержащие все эти слова в ответе и запросе. Обратите внимание, что словосочетания в кавычках обрабатываются как единый поисковый запрос, поэтому для запроса [неделя "количество событий"] будут показаны результаты, где есть фраза "количество событий". Кроме того, поисковые запросы могут быть представлены парами "поле – поисковая фраза", например [requst.url:поисковая_фраза request.method:поисковая_фраза response.status:поисковая_фраза]. Для более сложного поиска можно использовать операторы, создавать группы и указывать поля. Оператор влияет на непосредственно следующую за ним поисковую фразу, изменяя способ ее поиска в целой группе или запросе. Поддерживаемые операторы: & : оператор по умолчанию, выполняющий операцию AND для результатов следующего поискового запроса и результатов всех предыдущих операций. | : выполняет операцию OR для результатов следующего поискового запроса и результатов всех предыдущих операций. ^ : выполняет операцию XOR для результатов следующего поискового запроса и результатов всех предыдущих операций. - : исключает результаты следующего поискового запроса. Выберите HAR-файл.
