用 selenium python 填充或忽略所需的随机字段

Question

我正在练习使用 selenium 登录网站 并获取抵押票据（print/save/download pdf 格式）。

登录页面如下：

字段1：合同号

字段 2：国家用户 ID

Botton：用于验证合约的Botton

字段 3：每次页面 accessed/refreshed

当我在整个用户页面（每个月）登录它时，当涉及到一些我不记得的偶然信息（例如国家健康 ID 或选民登记）时，我刷新页面直到它给我带来了一些容易记住的信息（phone 号码、邮政编码等）。

我该怎么做才能通过最后一个以随机方式请求个人信息的字段（有些我知道，有些我不知道）？

第三个字段的网站代码如下。参数 name="zipCode" 和 placeholder="Zip Code" 部分是每次刷新页面时不断更改其值的部分。

input id="aleatoryField" class="mat-input-element mat-form-field-autofill-control 
ng-tns-c4-1 cdk-text-field-autofill-monitored ng-dirty ng-invalid ng-touched" 
_ngcontent-iqu-c4="" autocomplete="off" 
formcontrolname="aleatoryField" inputmode="decimal" matinput=""
pattern="[0-9]*" required="" name="zipCode" placeholder="Zip Code"
aria-describedby="mat-error-2" aria-invalid="true" aria-required="true"

input id="aleatoryField" class="mat-input-element mat-form-field-autofill-control ng-tns-c4-1 cdk-text-field-autofill-monitored ng-dirty ng-invalid ng-touched" 
_ngcontent-iqu-c4="" autocomplete="off" 
formcontrolname="aleatoryField" inputmode="decimal" matinput=""
pattern="[0-9]*" required="" name="voterId" placeholder="Voter Registration"
aria-describedby="mat-error-2" aria-invalid="true" aria-required="true"

input id="aleatoryField" class="mat-input-element mat-form-field-autofill-control ng-tns-c4-1 cdk-text-field-autofill-monitored ng-dirty ng-invalid ng-touched" 
_ngcontent-iqu-c4="" autocomplete="off" 
formcontrolname="aleatoryField" inputmode="decimal" matinput=""
pattern="[0-9]*" required="" name="yearBirth" placeholder="Year of Birth"
aria-describedby="mat-error-2" aria-invalid="true" aria-required="true"


# MY CURRENT CODE

from selenium import webdriver

driver = webdriver.Firefox(executable_path="./geckodriver.exe" )

# open the website
driver.get("https://www.habitacaodigital.caixa.gov.br/acesso-cliente")

# FIELD 1: contract info
contract = driver.find_element_by_id("contract")
national_id = driver.find_element_by_id("nationalId")

# FIELD 2: filling the contract info
contract.send_keys("123")
national_id.send_keys("321")

# botton
validate_contract = driver.find_element_by_id("validate_contract")
validate_contract.click()

# FIELD 3: aleatory personal info field (cellphone number, zip code, day of birth, mother's name...)
# aleatory_field = driver.find_element_by_id("aleatoryField")
# aleatory_field.send_keys("HOW TO DEAL WITH THIS PART OVER HERE?")

# undetected Selenium suggestion
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#aleatoryField[formcontrolname='aleatoryField']"))).send_keys("234567")

# LOGGING BOTTON
btn_logging = driver.find_element_by_id("btn_access")
btn_logging.click()

添加了未检测到的 Selenium 第一个建议的结果

Answer 1

要将 字符序列 发送到 <input> 元素，您需要引入 WebDriverWait for the and you can use either of the following :

使用CSS_SELECTOR:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#aleatoryField[formcontrolname='aleatoryField']"))).send_keys("234567")

使用 XPATH:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@id='aleatoryField' and @formcontrolname='aleatoryField']"))).send_keys("234567")

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

Answer 2

您似乎对动态元素没有问题，因为元素 id 从未更改过。您遇到基于字段类型的输入值问题 name 出现在每次登录的屏幕上。

您可以使用 python switch case 并配置所有 return 类型 attribute name 然后调用该函数，如果它与特定的 name 匹配，则仅使用您的代码执行该块输入。

def SetInputValue(element, elementAttVal):
    match elementAttVal:
        case "zipCode":
            element.send_keys("400910")
        case "voterId":
             element.send_keys("1234588999")
        case "yearBirth":
            element.send_keys("1990")     
            
//identify the element 
element=WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "input#aleatoryField")))
//Get the name attribute value
elementAttVal=element.get_attribute("name")
print(elementAttVal)
//Set the input based on name attribute
SetInputValue(element,elementAttVal)

更新：使用 if..block 这样你也添加了剩余的配置

def SetInputValue(element, elementAttVal):
        if elementAttVal=="zipCode":
                element.send_keys("400910")
        if elementAttVal=="voterId":
                element.send_keys("1234588999")
        if elementAttVal=="yearBirth":
                element.send_keys("1990")     
                
    //identify the element 
    element=WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "input#aleatoryField")))
    //Get the name attribute value
    elementAttVal=element.get_attribute("name")
    print(elementAttVal)
    //Set the input based on name attribute
    SetInputValue(element,elementAttVal)
