接着上篇随笔 selenium-配置文件定位元素 ，进行了配置文件设置后，将配置文件运用到定位元素中
思路：拿到定位的 key 和 value 后，对 webdrvier 中定位进行封装，使可以直接运用
主要的8种定位方法：
- find_element_by_id
- find_element_by_name
- find_element_by_xpath
- find_element_by_link_text
- find_element_by_partial_link_text
- find_element_by_tag_name
- find_element_by_class_name
- find_element_by_css_selector
# conding=utf-8from selenium import webdriverfrom auto_learning.config import ReadIni #导入读取的配置文件的py文件，如果不能导入检查是否是包（__init__.py文件存在 ）文件class FindElement(object): ???def __init__(self,driver): ???????self.driver = driver ???def get_Element(self,pageElement,key): ???????# 实例化ReadIni ???????file_name = ‘../config/BaiduElement.ini‘ ???????read_ini = ReadIni.ReadIni(file_name) ???????key_value = read_ini.get_value(pageElement,key) ???????key = key_value.split(‘:‘)[0] ???????value = key_value.split(‘:‘)[1] ???????try: ???????????if key == ‘id‘: ???????????????return self.driver.find_element_by_id(value) ???????????elif key == ‘class‘: ???????????????return self.driver.find_element_by_class_name(value) ???????????elif key == ‘name‘: ???????????????return self.driver.find_element_by_name(value) ???????????elif key == ‘tag‘: ???????????????return self.driver.find_element_by_tag_name(value) ???????????elif key == ‘linkText‘: ???????????????return self.driver.find_element_by_link_text(value) ???????????elif key == ‘cssSelector‘: ???????????????return self.driver.find_element_by_css_selector(value) ???????????elif key == ‘xpath‘: ???????????????return self.driver.find_element_by_xpath(value) ???????except: ???????????return None
由于浏览器有好多种，所以也需要重新定义浏览器的启动
对构造函数进行修改
???def __init__(self,driverName): ???????try: ???????????if driverName == ‘chrome‘: ???????????????self.driver = webdriver.Chrome() ???????????elif driverName == ‘dege‘: ???????????????self.driver = webdriver.Edge() ???????????elif driverName == ‘firefox‘: ???????????????self.driver = webdriver.Firefox() ???????????elif driverName == ‘safari‘: ???????????????self.driver = webdriver.Safari() ???????except: ???????????error_message = "find not " + driverName ???????????print(error_message) ???????self.driver.maximize_window() ???????url = ‘https://www.baidu.com‘ ???????self.driver.get(url)
在项目中如果用单一浏览器可能会造成堵塞
所以就需要多个浏览器同时跑脚本，不至于一个浏览器的压力太大
# conding=utf-8from selenium import webdriverimport timefrom auto_learning.config import ReadIni #导入读取的配置文件的py文件，如果不能导入检查是否是包（__init__.py文件存在 ）文件class FindElement(object): ???def __init__(self,i): ???????self.driver = self.get_driver(i) ???????time.sleep(3) ???????url = ‘https://www.baidu.com‘ ???????self.driver.get(url) ???????self.driver.maximize_window() ???def get_driver(self,i): ???????if i == 0: ???????????return webdriver.Chrome() ???????elif i == 1: ???????????return webdriver.Edge() ???????elif i == 2: ???????????return webdriver.Firefox() ???????elif i == 3: ???????????return webdriver.Safari() ???def get_Element(self,pageElement,key): ???????# 实例化ReadIni ???????file_name = ‘../config/BaiduElement.ini‘ ???????read_ini = ReadIni.ReadIni(file_name) ???????key_value = read_ini.get_value(pageElement,key) ???????key = key_value.split(‘:‘)[0] ???????value = key_value.split(‘:‘)[1] ???????try: ???????????if key == ‘id‘: ???????????????return self.driver.find_element_by_id(value) ???????????elif key == ‘class‘: ???????????????return self.driver.find_element_by_class_name(value) ???????????elif key == ‘name‘: ???????????????return self.driver.find_element_by_name(value) ???????????elif key == ‘tag‘: ???????????????return self.driver.find_element_by_tag_name(value) ???????????elif key == ‘linkText‘: ???????????????return self.driver.find_element_by_link_text(value) ???????????elif key == ‘cssSelector‘: ???????????????return self.driver.find_element_by_css_selector(value) ???????????elif key == ‘xpath‘: ???????????????return self.driver.find_element_by_xpath(value) ???????except: ???????????return Noneif __name__ == ‘__main__‘: ???for i in range(3): ???????findElement = FindElement(i) ???????input_text = findElement.get_Element(‘BaiduHomeElement‘,‘baidu_search_input‘)
