I can't find a vacancy unless I keep an eye on the skill training reservation of the driving school 24 hours a day, so I'm studying python to automate the system.

I made a command line electronic mailer that came out in Exercise 11.10.1 of the title book, so I tried to organize it.

I used Excite mail this time, but the reason is that Gmail and yahoo had some kind of multi-step authentication, so it was Excite mail that I could easily log in with just my id and password.

environment

python 3.6.0
PyCharm 2017.1
MacbookAir sierra 10.12.5 --Safari turns on "Allow remote automation"

policy

--Receive email address and text from command line --Log in to Excite mail with selenium --Create a new email and send the text to the email address you received as an argument

Program policy

--Use the sys module to receive text at the email address sys.argv [2] at sys.argv [1]. --Open the login page of Excite mail with the webdriver of the selenium module, send the user name and password with sendKeys, and log in with submit (). --Open the email sending screen from the newly created link, enter the email address and text received as an argument, and submit ()

Implementation

`CommandlineMailer.py`


#! python 3.6.0
# commnadlineMailer.py -Send text to the email address you received on the command line
# Usage:
# commnadlinMailder.py <[email protected]> <sometext> -Email address as the first argument,Receive text as the second argument

import sys
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

if len(sys.argv) > 2:
    email_adress = str(sys.argv[1])
    main_text = str(sys.argv[2])

    #Open Excite email and log in
    browser = webdriver.Safari()
    browser.get('https://ssl2.excite.co.jp/idc/login/?si=mail&ru=http%3A%2F%2Femail.excite.co.jp')
    #I used the name tag because there was no id tag
    email_elem = browser.find_element_by_name('loginid') 
    email_elem.send_keys('[email protected]')

    password_elem = browser.find_element_by_id('id-password')
    password_elem.send_keys('yourPassword')
    password_elem.submit()

    #After waiting for the page to be displayed, open the new creation screen
    link_elem = WebDriverWait(browser, 10).until(
        EC.element_to_be_clickable((By.LINK_TEXT, 'Create New'))
    )
    link_elem.click()

    #After waiting for the page to be displayed, enter the email address and text and send
    to_elem = WebDriverWait(browser, 10).until(
        EC.presence_of_element_located((By.ID, 'to'))
    )
    to_elem.send_keys(email_adress)

    main_text_elem = browser.find_element_by_id('body')
    main_text_elem.send_keys(main_text)

    send_elem = browser.find_element_by_id('_sendmail')
    send_elem.submit()
else:
    print('There are few arguments')

The point that got caught

At first, I was implementing it without waiting for the display, and the error came out and I felt like "?", But I noticed that an error occurred when I accessed it when it was not displayed.

The point was to use WebDriverWait to stop processing "until a specific element appears ≒ until the update is successful". If it cannot be updated within the 10 seconds specified by WebDriverWait (browser, 10), a timeout error will be returned.

The point that I cut corners

Since it is used only in the exercise, I omitted checking whether it is an email address with a regular expression and processing when the argument is reversed.
