为什么错误发生 python3 与 selenium

Question

我最近在学习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()

结果错误就在这里

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

我认为错误是因为此代码的数量包括十进制。但我找不到这样的号码。

请给我建议

Answer 1

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。

根据您使用 webdriver.Remote() 和参数 command_executor 的代码试验，也许您正试图在 Selenium Grid Configuration 中执行测试。

根据文档documentation：

• command_executor：remote_connection.RemoteConnection 对象用于执行命令。

  • 例子：

    command_executor='http://127.0.0.1:4444/wd/hub'
    

  • 完整的实现：

    driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities = chrome_options.to_capabilities())
    

注意：这里我们认为 Selenium Grid Hub 和 Selenium Grid Node 已配置成功，并且默认配置为 on本地主机。

解决方案（Python 3.6）

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()
