使用python而不是cgi从html表单获取数据

Question

I would like get the data from a basic html form

    <form method="send" action="/send">
    Name <input type="text"  name="name"/>
    <input type="submit" value="Send">
</form>

into a python file. Is that possible or not? I do not want to have to use CGI. thanks Josh

Answer 1

Whether you will need to battle with CGI, depends on your use case.

Python frameworks. like Flask , tend to offer their own litte web servers out-of-the-box. However, such servers are mostly meant for testing during the development phase. Integration into full blown web browsers usually is via CGI or FastCGI, and can offer advanced customization and scale up to huge loads.

But, depending on your target audience, a good "included" web server, like the one in web2py will do for you. For learning purposes, or in a closed network behind a firewall, such solutions are perfectly ok and you aviod the tech CGI stuff. Once your app is finished or the "included" web server will not suit your needs anymore, you can still deploy your app behind a "real" web server.

If you really like it the tough way, you may also consider to write your own web server from scratch ;)

Answer 2

Python work on server side. Browser work on client side. They communicate via network. So it is imposible to do that without CGI ar any CGI-like method (FastCGI, PSGI, WSGU etc...). The best way for Python is WSGI.

If I am understanding your question correctly you could use the selenium module. As an example, if you wanted to get the source code from Google, your code would be:

from selenium import webdriver
driver = webdriver.Chrome() # Or Firefox, or whatever browser you use
driver.get('https://google.com')
data = driver.page_source

The source code for Google is now stored in the data variable.
