在python中调用URL的正确方法是什么

Question

我有csv文件，并且将csv数据传递给python代码有参数。 在csv文件中有URL数据。 在python中调用URL的正确方法是什么。 出现错误Cannot navigate to invalid URL

CSV文件

ID,category,link
sports_shoes,sports-shoes,https://www.flipkart.com/mens-footwear/sports-shoes/pr?otracker=categorytree&page=1&sid=osp%2Ccil%2C1cu

码：

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

with open('mydata.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        #print(row['ID'] ,row['category'],row['link'])
        url = row['link']
        print(url)
        chrome_path = r"C:\Users\Venkatesh\AppData\Local\Programs\Python\Python35\chromedriver.exe"
        driver = webdriver.Chrome(chrome_path)
        RegionIDArray = url
        data_list=[]
        data = []
        mobile_details_data = []
        delay = 30 # seconds
        for reg in RegionIDArray:
            driver.get(reg)
driver.quit()

错误：

Answer 1

您的url变量包含您要访问的链接。 您的代码遍历字符串，并在每个字符上调用driver.get() 。 基本上可以解释错误。

因为，您已经for row in reader:中的for row in reader:遍历数据，所以不需要内部循环。 只需使用driver.get(url) 。
