问题描述
我正在使用selenium/phantomjs在python中创建html的png文件.有没有办法从html字符串或文件句柄(而不是网站)生成png?我已经搜索了硒文档并用谷歌搜索，但是找不到答案.我有:
I am using selenium/phantomjs to create png files of html in python. Is there a way to generate the png from an html string or filehandle (instead of a website)? I've searched through the selenium docs and googled but couldn't find an answer. I have:
htmlString = '<html><body><div style="background-color:red;height:500px;width:500px;">This is a png</div></body></html>'
myFile = 'tmp.html'
f = open(myFile,'w')
f.write(htmlString)
from selenium import webdriver
driver = webdriver.PhantomJS()
driver.set_window_size(1024, 768)
#driver.get('https://google.com/') # this works fine
driver.get(myFile) # passing the file name or htmlString doesn't work...creates a blank png with nothing
driver.save_screenshot('screen.png')
driver.quit()
print "png file created"
推荐答案
PhantomJS
var page = require('webpage').create();
page.open('http://github.com/', function () {
page.render('github.png');
phantom.exit();
});
