如何使用Selenium和Python在网站内的页面中导航？

问题描述 投票：0回答：2

我正在搜刮这个网站( http:/rera.rajasthan.gov.inProjectSearch。)使用Python和Selenium。我的代码可以用了，但是目前只刮取了第一页，我想遍历所有的页面，并刮取其中所有的VIEW，但是他们处理分页的方式很奇怪，我怎么才能一个一个地去刮取这些页面呢？

我的源码。

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException, WebDriverException
import time

opt = webdriver.ChromeOptions()
opt.add_argument("--ignore-certificate-errors")
opt.add_argument("--start-maximized")

driver = webdriver.Chrome(executable_path=r"C:\Users\fit foodie\PycharmProjects\Selenium\Browser\chromedriver.exe", options=opt)

driver.get(url="http://rera.rajasthan.gov.in/")
search= driver.find_element_by_xpath("//*[@id='liSearch']/a").click()
proj_src=driver.find_element_by_xpath("//*[@id='liSearch']/ul/li[1]/a").click()

search_btn = driver.find_element_by_xpath('//*[@id="btn_SearchProjectSubmit"]').click()


def page():
    while True:
        try:
            driver.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(driver, 20).until(
                EC.element_to_be_clickable((By.XPATH, "//*[@id='OuterProjectGrid']/div[4]/div[4]/a"))))
            driver.find_element_by_xpath("//*[@id='OuterProjectGrid']/div[4]/div[4]/a").click()
            print("Navigating to Next Page")
        except (TimeoutException, WebDriverException) as e:
            print("Last page reached")
            break

无法通过这个来分页

对于 Pagination 使用以下内容 css 选择器，并在每次点击后提供延迟。

def page():
    i=2
    while True:
        try:
            driver.execute_script("arguments[0].scrollIntoView();", WebDriverWait(driver, 20).until(
                EC.element_to_be_clickable((By.CSS_SELECTOR, "a[data-p='{}']".format(i)))))
            driver.find_element_by_css_selector("a[data-p='{}']".format(i)).click()

            print("Navigating to Next Page " + str(i))
            i=i+1
            time.sleep(1)
        except (TimeoutException, WebDriverException) as e:
            print("Last page reached")
            break

page()

輸出：控制台快照

如果你的目标是获取所有页面的所有表格数据，你可以不需要 硒 你也可以试试python requests 模块，并使用 职位 请求。

import requests
data={
    "PageSize" :1250,
    "page": 1
}
res=requests.post("http://rera.rajasthan.gov.in/Home/GetProjectsList",data=data).json()
for item in res['Data']['Items']:
    print(item['DistrictName'],item['ProjectName'],item['ProjectTypeName'],item['PromoterName'],item['ApplicationNo'],item['CertificateNo'])

对所有这样的页面进行输出。

从网站内的搜索中搜出所有的结果页面。http:/rera.rajasthan.gov.inProjectSearch。 使用 蟒蛇 和 硒 你需要诱导 WebDriverWait 对于 element_to_be_clickable() 您可以使用以下方法 定位策略:

  • 代码块。

    driver.get("http://rera.rajasthan.gov.in/ProjectSearch")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='dropdown-toggle' and contains(., 'Search')]"))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='dropdown-toggle' and contains(., 'Search')]//following::ul[1]/li/a[text()='Project Search']"))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='btn btn-primary']"))).click()
while True:
    try:
        WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='ds4u-footer']//div[@class='ds4u-pager']//a")))
        WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='ds4u-footer']//div[@class='ds4u-pager']//a[contains(@class, 'ds4u-selected')]//following::a[1]/span"))).click()
        print("Clicked for next page")
    except TimeoutException:
        print("No more pages to navigate")
        break
