나는 위의 cURL을 사용하여 수행 할 수 있지만,이 시점에서 나는 붙어있다.
일단 결과 페이지에 나타나면 "날짜"헤더를 두 번 클릭하여 데이터 순서를 낮추고 그 다음 현재 날짜의 결과를 빼내야합니다.
이 방법, 고급 세부 사항 또는 개념을 어떻게 생각합니까? 어느 쪽이든 도움이됩니다.
감사합니다.
결과를 얻을 수있는 더미 데이터를 게시 할 수 있다면 도움이 될만한 결과 집합을 얻을 수 없습니다.
일반적인 대답으로 DOM을 조작 할 수있는 무언가가 필요합니다. PHP 및 Webdriver와 같은 서버 측 또는 Selenium을 통한 클라이언트 측으로 이동할 수 있습니다. 클릭을 시뮬레이트하고 결과 HTML을 가져 와서 구문 분석하십시오.
문제는 클릭이 자바 스크립트를 사용하여 포스트 백을 실제로 수행하고 PHP 및 cURL의 제한 사항으로 인해 브라우저에서 전송 된 HTTP 헤더 (GET, POST 및 COOKIES)를 검사하고 에뮬레이션해야합니다. 일부 값은 세션에 따라 다를 수 있음을 명심하십시오. 지금 당장이 작업을 수행 할 시간이 없지만 일부 경우 ASP.Net 웹 사이트에서 상당히 까다로워 질 수 있습니다. 더 쉬운 방법이있을 수 있지만, 항상 그렇게 될 것입니다. 왜냐하면 그렇게되기 때문입니다.
PHP에 묶이지 않은 경우 전 세계의 옵션이 열려 있습니다. 예를 들어, 내가 작업하고있는 프로젝트의 집계 도구는 실제로 이러한 종류의 작업/페이지에 대해 (제어 된) JavaScript를 실제로 실행할 수 있습니다. 그래도 더 큰 규모로).
이렇게하면됩니다. 이 시도.
