用python的seleniumy自動登入pixiv搜尋關鍵字

本來想做用python自動爬取pixiv圖片,但pixiv有防爬蟲要用requests,所以先把用selenium寫得傳出來.

import time

from selenium import webdriver

from selenium.webdriver.common.by import By

from selenium.webdriver.support.ui import WebDriverWait

from selenium.webdriver.support import expected_conditions as EC

from selenium.webdriver.common.keys import Key

path = "C:/Users/Administrator/Desktop/chromedriver/chromedriver.exe"

driver = webdriver.Chrome(path)

def pixiv(name, key, keyword):

driver.get("https://www.pixiv.net/")

login = driver.find_element_by_xpath('//*[@id="wrapper"]/div[3]/div[3]/div/div[2]/a[4]')

time.sleep(1)

login.click()

time.sleep(1)

login_two = WebDriverWait(driver, 10).until(

EC.presence_of_element_located((By.XPATH, '//*[@id="loginbutton"]'))

)

username = WebDriverWait(driver, 10).until(

EC.presence_of_element_located((By.XPATH, '//*[@id="email"]'))

)

passkey = WebDriverWait(driver, 10).until(

EC.presence_of_element_located((By.XPATH, '//*[@id="pass"]'))

)

username.clear()

passkey.clear()

username.send_keys(name)

passkey.send_keys(key)

login_two.click()

WebDriverWait(driver, 10).until(

EC.presence_of_element_located((By.XPATH, '//*[@id="root"]/div[2]/div[1]/div[1]/div[1]/div/div[2]/form/div/input'))

)

sreach = driver.find_element_by_xpath('//*[@id="root"]/div[2]/div[1]/div[1]/div[1]/div/div[2]/form/div/input')

sreach.send_keys(keyword)

sreach.send_keys(Keys.RETURN)

首先要用到selenium, time

要先載入這兩個模組.

要使用selenium要先下載你使用的瀏覽器對應的driver

我用的是google所以我下載chromedriver(https://chromedriver.chromium.org/)

把chromedriver的路徑放入一個變數

path = "C:/Users/Administrator/Desktop/chromedriver/chromedriver.exe"

設定用chrome打開

driver = webdriver.Chrome(path)

開啟pixiv

driver.get("https://www.pixiv.net/")

選用facebook開啟

login = driver.find_element_by_xpath('//*[@id="wrapper"]/div[3]/div[3]/div/div[2]/a[4]')

點下按鈕

login.click()

停一秒

time.sleep(1)

再點下後會有頁面跳轉,所以用webdriverwait,直到出現帳號密碼才繼續,其實用time.sleep也可以

login_two = WebDriverWait(driver, 10).until(

EC.presence_of_element_located((By.XPATH, '//*[@id="loginbutton"]'))

)

username = WebDriverWait(driver, 10).until(

EC.presence_of_element_located((By.XPATH, '//*[@id="email"]'))

)

webdriverwait會回傳一個質,所以用clear()清除

username.clear()

passkey.clear()

輸入帳密

username.send_keys(name)

passkey.send_keys(key)

找到搜索框

sreach = driver.find_element_by_xpath('//*[@id="root"]/div[2]/div[1]/div[1]/div[1]/div/div[2]/form/div/input')

輸入關鍵字

sreach.send_keys(keyword)

按enter,Key是引入進來的函數,在send_keys中輸入Keys.RETURN就是按下enter

sreach.send_keys(Keys.RETURN)

之後就只要呼叫函式就可以了

函式中的name, key, keyword需打成字串,不然會錯誤
