Selenium2+python Automation 40-cookie related operations

Objective

Although cookie-related operations are used less often in normal UI automation, they are occasionally used, such as login with a graphics verification code, you can bypass the authentication code method, add a cookie method to log in.

Login After login, also can be used as a post-condition to delete the cookie and then the next account login

I. Acquisition of Cookies:get_cookies ()

1. Methods of obtaining cookies directly by: Get_cookies ()

2. Start the browser first, get the cookies, print out the Found is empty: []

3. After opening the homepage of the blog, re-obtain the cookies, print out, there is a value

Second, after the login of the cookies

1. Log in to the blog Park first (login here with your own account and password bar)

2. Re-access cookies, found not the same as previously acquired

3. The main thing is to find this cookie and find that its name and value have changed, which is the difference between not logged in and logged in (compare the top and bottom two graphs)

{u ' name ': U '. Cnblogscookie ', U ' value ': U ' b7813eba142142ce88cc8c0b33b239f566xxxx '}

Third, get the name of the Cookie:driver.get_cookie (name) specified

1. Get cookies found there are multiple cookies, sometimes we only need one of them, put important, such as login cookie

2. Use Get_cookie (name) to specify the name value of the corresponding cookie, as in the blog Park:. Cnblogscookie

Iv. clear the specified Cookie:delete_cookie ()

1. In order to further verify that the previous step obtained is the login cookie, you can delete it to see what changes the page

2. After deleting this cookie, refresh the page and find that the login is invalid and become not logged in.

V. Clear All cookies:delete_all_cookies ()

1. After clearing all cookies, the login status also expires, and the cookies are blank []

Vi. Several methods of cookie operation

1.get_cookies (): Get All Cookies

2.driver.get_cookie (name): Gets the cookie for the specified name:

3. Clear the specified Cookie:delete_cookie ()

4.delete_all_cookies (): Clear All Cookies

5.add_cookie (cookie_dict): Adding the value of a cookie

(The fifth method can be used to bypass the verification code login, detailed in the next article)
