selenium===splinter模块和selenium异曲同工

安装以后用它来实现163邮箱的登陆操作：
*和selenium一样，splinter同样需要对frame进行切换

from splinter import Browser

browser = Browser()
browser.visit('https://mail.163.com')

# 163的登录框在iframe中,所以无法使用dom查找,可以splinter提供的相关API

with browser.get_iframe('x-URS-iframe') as iframe:
 iframe.find_by_name('email').fill('yourName')
 iframe.find_by_name('password').fill('yourPassWord')
 iframe.find_by_id('dologin').click()
 iframe.find_by_text('继续登录').click()

if b.is_text_present('写信'):
    print('yes!')
else:
    print("sorry!")

browser.fill('email','xxxx')                #by_name        field = self.find_by_name(name).first

关于查找元素的方法：

Splinter provides 6 methods for finding elements in the page, one for each selector type: css, xpath, tag, name, id, value, text. Examples:

browser.find_by_css('h1')
browser.find_by_xpath('//h1')
browser.find_by_tag('h1')
browser.find_by_name('name')
browser.find_by_text('Hello World!')
browser.find_by_id('firstheader')
browser.find_by_value('query')

If you need to find the links in a page, you can use the methods find_link_by_text, find_link_by_partial_text, find_link_by_href or find_link_by_partial_href. Examples:

links_found = browser.find_link_by_text('Link for Example.com')
links_found = browser.find_link_by_partial_text('for Example')
links_found = browser.find_link_by_href('http://example.com')
links_found = browser.find_link_by_partial_href('example')

表单切换：get_iframe(name)

Changes the context for working with iframes.

You can use the get_iframe method and the with statement to interact with iframes. You can pass the iframe’s name, id, or index to get_iframe.

with browser.get_iframe('iframemodal') as iframe:
    iframe.do_stuff()

#for example

with browser.get_iframe('x-URS-iframe') as iframe:
 iframe.find_by_name('email').fill('yourName')
 iframe.find_by_text('继续登录').click()
