안녕하세요. 이번에 크롤링 강의를 듣고 있는 수강생 입니다. 현재 네이버 지도에서 위치를 검색 후 클릭 -> 클릭-> 한 후 네이버의 한줄평 리뷰 를 크롤링 하는 자체 프로젝트를 진행중입니다. 이때, 검색창을 찾고, click() 을 이용해 Crawling 을 위한 (3) 페이지 로딩까지는 성공하였으나, 옆의 화면에서 click 및 어떠한 활동도 할 수 없는 상태입니다. 제 소스 코드는 이렇습니다. for l in list_loc: ele = l.split(( ',' ))[:- 1 ] comp = unicodedata.normalize( 'NFC' , ele[- 1 ][- 1 ]) if comp != dong and comp != eup and comp != myun and comp != lee and comp != ga : continue address = ele[ 0 ]+ ' ' +ele[ 1 ]+ ' ' +ele[ 2 ]+ ' 식당 ' add_quote = urllib.parse.quote(address) driver.get(url) sleep( 1 ) key_search = address time_wait( 2 , 'div.input_box > input.input_search' ) search = driver.find_element(By.CSS_SELECTOR , 'div.input_box > input.input_search' ) sleep( 1 ) search.send_keys(key_search) search.send_keys(Keys.ENTER) res = driver.page_source soup = BeautifulSoup(res , 'html.parser' ) # html 파싱하여 가져온다 sleep( 1 ) def switch_frame (frame): driver.switch_to.default_content() # frame 초기화 driver.switch_to.frame(frame) # frame 변경 res soup def page_down (num): body = driver.find_element(By.CSS_SELECTOR , 'body' ) body.click() for i in range (num): body.send_keys(Keys.PAGE_DOWN) switch_frame( 'searchIframe' ) page_down( 3 ) sleep( 1 ) # 매장 리스트 store_list = driver.find_elements(By.CSS_SELECTOR , '._1EKsQ' ) next_btn = driver.find_elements(By.CSS_SELECTOR , '._2ky45 > a' ) print ( len (next_btn) , '....' ) for btn in range ( len (next_btn))[ 1 :]: # next_btn[0] = 이전 페이지 버튼 , 1,2 : 광고 / 0,1,2 무시 -> [3] 부터 시작 print (next_btn[btn].text , 'adsadsa' ) store_list print (store_list[ 0 ].text) store_page = driver.find_elements(By.CSS_SELECTOR , '.OXiLu' ) for data in range ( len (store_list)): # 매장 리스트 만큼 #print(data, len(store_page), store_page[data].text, '00') store_page[data].click() sleep( 2 ) try : driver.switch_to.default_content() print ( 'switch test1' ) sleep( 0.5 ) driver.switch_to.frame( 'entryIframe' ) sleep( 4 ) print ( 'switch test2' ) reviews = driver.find_elements(By.CSS_SELECTOR , '_2RG_o' ) except : pass 여기서, (3) 의 페이지가 네이버 지도의 entryIframe 안에 있는 것을 알고, switch frame 을 시도했습니다만, 무슨 락이 걸려 있는것인지 저 entryIframe 이 전혀 검색이 되지 않습니다. 하지만 소스 페이지 검색 결과, entryIframe 는 분명이 존재합니다. 제가 무엇을 빼먹은 것인지, 무엇을 잘못 하고 있는 것인지 알고 싶습니다. 감사합니다.
