Python Proxy for html2canvas (tested in Python 2.7.3)
Although I have just added an example with "Flask" is library works with any "Python Web framework." Soon I'll add examples with other frameworks.
You do not use PHP, but need html2canvas working with proxy, see other proxies:
- html2canvas proxy in php
- html2canvas proxy in asp.net (csharp)
- html2canvas proxy in asp classic (vbscript)
| Module | Description |
|---|---|
html2canvasproxy([callback get param], [url get param]) |
Config html2canvasproxy |
html2canvasproxy.enable_crossdomain() |
Enable the use of "Data URI scheme" |
html2canvasproxy.useragent([user agent]) |
Config webbrowser user-agent |
html2canvasproxy.hostname([url]) |
Config current URL (requires scheme and port) |
html2canvasproxy.referer([referer]) |
Config referer page (If needed) |
html2canvasproxy.route([real path], [virtual path]) |
Config "route" for images and real path (folder to save images). Note: "real path" is absolute path eg. /home/user/project1/images, "virtual path" should be as you want it to appear in the "address bar", eg. /images |
html2canvasproxy.debug_vars() |
Get variables values for DEBUG |
html2canvasproxy.result() |
Run proxy/Get response and mime-type by proxy. |
html2canvasproxy.resource([real path], [image]) |
Get resource saved and mime-type by proxy "real path" is same in html2canvas.route([real path], [virtual path]). Read Get resources with proxy |
A simple example of usage
from html2canvasproxy import * #Load html2canvasproxy #Set GET variables h2c = html2canvasproxy(request.args.get("callback"), request.args.get("url")) #Uncomment next line to enable "data URI scheme" (optional) #h2c.enable_crossDomain() #Set user-aget browser if request.headers['user_agent']: h2c.useragent(request.headers['user_agent']) else: h2c.useragent('Mozilla/5.0') #Set current page h2c.hostname(request.url) #Set referer (If needed) if request.referer: h2c.referer(request.referer) #Set route (real path and virtual path) h2c.route('/home/guilherme/projects/site/images', '/images') #Results print 'Debug:' print h2c.debug_vars() print '---------' result = h2c.result() print 'mime: ' + result['mime'] print 'data: ' + result['data'] print '=========\n'
Run proxy/Get response and mime-type by proxy (returns application/javascript)
r = h2c.result() print r['mime'] print r['data']
Get resource saved and mime-type by proxy (returns images or html)
res = html2canvasproxy.resource(real_path, image) print res['mime'] print res['data']
