为什么错误发生python与selenium

Question

我最近学习python，但是我有一些错误。

环境python3，chrome，webdriver（chrome）

from selenium import webdriver
import time
import random
import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

driver = webdriver.Chrome("./chromedriver.exe") 

mobile_emulation = { "deviceName": 'Nexus 5' }
chrome_options = webdriver.ChromeOptions()


chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)


driver = webdriver.Remote(command_executor='https:xxx.com',desired_capabilities = chrome_options.to_capabilities())


driver.get("https:/xxx.com")

num = random.randint(11111111 , 99999999)

red = driver.find_element_by_class_name("***")
red.click()

numBox = driver.find_element_by_name("***")
numBox.send_keys(int(num))

reader = driver.find_element_by_id("***")
reader.send_keys("***")

comment = driver.find_element_by_css_selector(" ***")
comment.click()

并且结果错误在这里

Traceback (most recent call last):
  File "C:\python\pad\pad.py", line 16, in <module>
    driver = webdriver.Remote(command_executor='https:xxx.com',desired_capabilities = chrome_options.to_capabilities())
  File "C:\Users\***\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 156, in __init__
    self.start_session(capabilities, browser_profile)
  File "C:\Users\***\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 254, in start_session
    self.session_id = response['sessionId']
TypeError: string indices must be integers

我认为错误，因为此代码的数量包括十进制。但是我找不到这个号码。

请给我建议

此错误消息...

Traceback (most recent call last):
  File "C:\python\pad\pad.py", line 16, in <module>
    driver = webdriver.Remote(command_executor='https:xxx.com',desired_capabilities = chrome_options.to_capabilities())
.
TypeError: string indices must be integers

...暗示在调用webdriver.Remote()方法时存在TypeError。

根据您的代码试验，因为您使用webdriver.Remote()和command_executor参数，或许您试图在Selenium Grid Configuration中执行测试。

根据文档documentation：

• command_executor：用于执行命令的remote_connection.RemoteConnection对象。 例： command_executor='http://127.0.0.1:4444/wd/hub' 完整的实施： driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities = chrome_options.to_capabilities())

注意：这里我们已经考虑使用localhost上的默认配置成功配置，启动和运行Selenium Grid Hub和Selenium Grid Node。

您的有效代码块将是：

from selenium import webdriver

chrome_options = webdriver.ChromeOptions() 
chrome_options.add_argument("start-maximized")
chrome_options.add_argument('disable-infobars')
#driver = webdriver.Remote(command_executor='https:xxx.com', desired_capabilities = chrome_options.to_capabilities())
driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities = chrome_options.to_capabilities())
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()
