Selenium Webdriver-Python-Leboncin（分类）-pb选择下拉列表&；箱

我继续学习Python/Selenium

成功连接到站点并选择按钮后，我想填充字段以提交分类广告

在这个阶段，我尝试选择两个字段，一个下拉列表和一个框。 Html如下所示

下拉列表

对于两者，我都有一个错误

错误消息

虽然我读过不同的帖子和selenium文档，但我还是有点被卡住了

提前感谢您的支持

最好的

完整的Python代码（我已设置了特定的凭据）

这应该适合您：）

要查找元素的xpath，请执行以下操作：

编辑： 只是对代码做了一些修改来测试它，它在firefox中工作得非常好

driver = webdriver.Firefox()
driver.maximize_window()
base_urldr = "https://compteperso.leboncoin.fr/account/index.html"
verificationErrors = []
accept_next_alert = True
driver.implicitly_wait(10)

wait = WebDriverWait(driver,10)
driver.get(base_urldr)
driver.find_element_by_name("st_username").clear()
driver.find_element_by_name("st_username").send_keys("thecoingood@gmail.com")
driver.find_element_by_name("st_passwd").clear()
driver.find_element_by_name("st_passwd").send_keys("thecoingood1")
driver.find_element_by_id("connect_button").click()
#driver.get("https://www2.leboncoin.fr/ai?ca=15_s")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//li[@class='deposer']"))).click()
driver.find_element_by_xpath("//*[@id='cat10']").click()
driver.find_element_by_xpath("//*[@id='subject']").send_keys("test")
time.sleep(10)

发布您的错误消息。感谢您的回复。我有相同的pb selenium.common.exceptions.WebDriverException:消息：处理命令时发生未知的服务器端错误。能否复制所有代码并将其粘贴到回复中？另外，试着运行我为你编写的代码，看看它是否有效。我已经用完整的代码编辑了这个问题，包括你的代码。请注意，我使用的是Safari web驱动程序（不确定是否有区别）。哦，我知道问题出在哪里了，您不能使用Safari，您需要使用Firefox或Chrome.：）谢谢，塞布。我使用的是MacOs中包含的嵌入式驱动程序。我目前正在审查如何安装gecko驱动程序。一旦完成并成功，我将结束主题。
