Python w/Selenium Gmail 电子邮件自动发送至：Field 给我带来了麻烦

Question

The end goal is to send myself an email if my public ip address changes, as I don't have dynamic dns and have to manually enter the ip addresses myself for my web server. I've done all I possibly can to try and get bash utilities to do the job for me, but CenturyLink is unfortunately out to block me no matter how I configure my outbound mail.

So I've turned to graphical python/selenium web page automation, which will sign into my gmail account for me, click the 'compose' button, then enter in the To:, Subject:, and text segments and hit send. Everything is working except for one small part - the To: field. The html/css is different for this than all the others and no matter how I try to select the field using

driver.find_element_by_class_name()

or

driver.find_element_by_id()

I just can't seem to fill out the field. Bash will give me an error like

:lo cannot be reached by keyboard 

or textarea#:lo.vO is not a valid selector

When I did an inspect element, the element looked like this:

<textarea rows="1" id=":lo" class="vO" name="to" spellcheck="false" autocomplete="false" autocapitalize="off" autocorrect="off" tabindex="1" dir="ltr" aria-label="To" role="combobox" aria-autocomplete="list" style="width: 462px;"></textarea>

My code so far is this: (note: which does not include getting ip info yet, just gmail login / manipulation)

from selenium import webdriver
import time

driver = webdriver.Firefox();
driver.get('https://www.gmail.com');
username = driver.find_element_by_id('identifierId');
username.send_keys("EMAIL");
driver.find_elements_by_class_name('RveJvd.snByac')[1].click();
time.sleep(2); #password not entered in username field
password = driver.find_element_by_class_name('whsOnd.zHQkBf');
password.send_keys("PASSWORD");
driver.find_elements_by_class_name('RveJvd.snByac')[0].click();

#end login, start composing

time.sleep(5); #wait for sign in
driver.find_element_by_class_name('T-I.J-J5-Ji.T-I-KE.L3').click();
to = driver.find_element_by_class_name('textarea#:lo.vO'); #incorrect
to.send_keys("EMAIL");
subject = driver.find_element_by_id(':l6');
subject.send_keys("IP Address changed");
content = driver.find_element_by_id(':m9');
content.send_keys("Test Test\n");

Answer 1

Have you tried to use the Gmail API? It's easier faster and more efficient than using Selenium.

Here's the quickstart: https://developers.google.com/gmail/api/quickstart/python

You can also use Python's built-in email package:

Answer 3

I think there seems to be a dynamic variation with the element ids in different browser. For me when I tried to compose the mail to fetch the XPATH I noted the XPATH was //*[@id=":oa"] but while the script launched it was //*[@id=":my"] .

To accommodate this I have used element querying using XPATH //textarea[1] as the Recipients section is always the first textarea . This proves to work well consistently across different browser sessions.

Try this code to send an email with Gmail. It has To, Subject and Send button functionality :

driver.find_element(By.XPATH, '//*[@id=":k2"]/div/div').click()# Compose button time.sleep(5)

driver.find_element(By.NAME, 'to').send_keys("Enter the email address of recipients")# to field in compose time.sleep(2)

driver.find_element(By.NAME,'subjectbox').send_keys("This email is send using selenium")# Subject field in compose time.sleep(2)

driver.find_element(By.XPATH,'//*[@id=":p3"]').click()# click on send button

time.sleep(5)

driver.close()
