我的问题是:我试图登录Wikifolio。com与Python和硒使用webdriver。
到目前为止，登录工作正常(对selenium的实际功能有非常基本的了解)。
我还设法点击了即将出现的免责声明按钮。
然后是一个“交易”按钮列表，每个按钮都连接到不同的资产。
当我点击“检查”的交易按钮，我得到以下xpath从网站:
//*[@id="root-wf-trading"]/div/div/table/tbody/tr[3]/td/table/tbody/tr[6]/td/div/a[1]
或者完整的xpath
/html/body/div[3]/main/div[3]/div[2]/div[1]/div/div/div[1]/div[2]/div/div/div[1]/div/div/table/tbody/tr[3]/td/table/tbody/tr[6]/td/div/a[1]
相应的HTML是
<a href="#add_virtual_order" rel="US88554D2053" data-amount="999" data-issuer="1900" data-description="3 D SYS CORP. DL-,001" data-security-type="620" class="add_virtual_order js-trade-button inline c-btn btn-trade-xsm u-mr-0 u-fs-s" data-main-editable="true" data-toggle="tooltip" data-placement="top" data-original-title="<div class='wikifolio-tooltip-text'>Neuen Trade platzieren</div>" aria-describedby="tooltip436117">Trade</a>
到目前为止，我使用的Python代码如下:
from selenium import webdriver
username = "*********"
password = "*********"
url = "https://www.wikifolio.com/dynamic/de/de/login/login?ReturnUrl=/de/de/home&_=1632037782306"
driver = webdriver.Chrome(executable_path=r'\Users\Benjamin\Downloads\chromedriver_win32\chromedriver.exe')
driver.get(url)
driver.find_element_by_name("Username").send_keys(username)
driver.find_element_by_name("Password").send_keys(password)
driver.find_element_by_css_selector("button").click()
driver.get("https://www.wikifolio.com/de/de/meine-wikifolios/trade/wf00wiking")
driver.find_element_by_css_selector(".c-disclaimer .js-disclaimer__abort, .c-disclaimer .js-disclaimer__change").click()
driver.find_element_by_xpath('/html/body/div[3]/main/div[3]/div[2]/div[1]/div/div/div[1]/div[2]/div/div/div[1]/div/div/table/tbody/tr[3]/td/table/tbody/tr[6]/td/div/a[1]').click()
当我尝试运行这段代码出现以下情况:
NoSuchElementException Traceback (most recent call last)

我能做什么？我如何找到及打开“交易”按钮？
非常感谢，并祝福本杰明
###你的定位器肯定不好，这就是为什么你得到NoSuchElementException.
。< br / >
为了给你正确的定位器我需要用有效的身份进入。< br / >
基于您提供的元素HTML而不是
driver.find_element_by_xpath('/html/body/div[3]/main/div[3]/div[2]/div[1]/div/div/div[1]/div[2]/div/div/div[1]/div/div/table/tbody/tr[3]/td/table/tbody/tr[6]/td/div/a[1]').click()
试试这个:
driver.find_element_by_xpath("//a[@data-toggle='tooltip' and(contains(@href,'add_virtual_order')) and(contains(@class,'add_virtual_order'))]").click()
此外，你必须在访问元素之前添加等待/延迟，就像这样:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
username = "*********"
password = "*********"
url = "https://www.wikifolio.com/dynamic/de/de/login/login?ReturnUrl=/de/de/home&_=1632037782306"
driver = webdriver.Chrome(executable_path=r'\Users\Benjamin\Downloads\chromedriver_win32\chromedriver.exe')
wait = WebDriverWait(driver, 20)
driver.get(url)
driver.find_element_by_name("Username").send_keys(username)
driver.find_element_by_name("Password").send_keys(password)
driver.find_element_by_css_selector("button").click()
driver.get("https://www.wikifolio.com/de/de/meine-wikifolios/trade/wf00wiking")
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".c-button--ghost"))).click()
wait.until(EC.visibility_of_element_located((By.XPATH, "//a[@data-toggle='tooltip' and(contains(@href,'add_virtual_order')) and(contains(@class,'add_virtual_order'))]"))).click()
