Hosting Company Doesn't Support WebApp2 - What Can I Use In Its Place?

问题

I'm trying to run a python file on a subdomain that I created. According to HostGator, python files are supported, but not the webapp2 framework, which I used throughout the file:

import webapp2
import cgi

def Build_Page(textarea_content):

form = """
<table>
    <tr>
    <td>
    <label>{0}</label>
    </td>
    <td>
    <label>Username: <input type="text" name="username"/></label>
    </td>
    </tr>

    <tr>
    <td>

    </td>
    </tr>

    <tr>

    <label>{3}</label>
    </td>
    <td>
    <label>Email (optional): <input type="text" name="email"/></label>
    </td>
    </tr>

</table>
"""
submit = "<input type = 'submit'/>"
form2 = ("<form method='post'>" + form + submit + "
</form>").format("Please enter a username",
"Please enter a password", "Passwords must match","Please enter a valid
email")

header = "<h1>User Signup</h1>" 

return header + form2

class MainHandler(webapp2.RequestHandler):
    def get(self):
        content = Build_Page("")
        self.response.write(content)

    def post(self):
    # look inside the request to figure out what the user typed
        username = self.request.get("username")
        password = self.request.get("password")
        verify_password = self.request.get("verify_password")
        email = self.request.get("email")
    # if the user typed nothing at all, redirect
        if (not username) or (username.strip() == ""):
            error = "Please enter a username."
            self.response.write(error)
            self.redirect("/?error=" + cgi.escape(error, quote=True))

        if (not password) or (username.strip() == ""):
            error = "Please enter a username."
            self.response.write(error)
            self.redirect("/?error=" + cgi.escape(error, quote=True))

        """if (not username) or (username.strip() == ""):

            quote=True))"""

    #self.write.form2    
    #message = self.request.get("message") # hello</textarea>hello
    #rotation = int(self.request.get("rotation")) # 0 
    #encrypted_message = caesar.encrypt(message, rotation) 
    #hello</textarea>hello
    #escaped_message = cgi.escape(encrypted_message) 
    # hello&lt;/textarea&gt;hello
    #content = build_page(escaped_message)
    #self.response.write(content)

    #original_form = form.format("","","","","","")
    #page footer

    #class TestHandler(webapp2.RequestHandler):
    #    """ Handles requests coming in to '/add'
    #        e.g. www.user-signup.com/add
    #    """
    #    def get(self):

app = webapp2.WSGIApplication([
    ('/', MainHandler),
    #('/', TestHandler)
], debug=True)

As far as I understand, webapp / webapp2 is what makes the Handlers + the functions inside of them work. Getting the username input in the "Username" label, for example, is made possible with webapp2.

Since HostGator doesn't support webapp2, what else can I use in its place? The technical support person at HostGator suggested I use PIP or maybe PyPI:

http://webpy.org/install

https://pypi.python.org/pypi

But after I install one of these packages and copy its folder to the directory for my subdomain, how do I know what command to use at the top of the file. Do I just say

import pip

and class MainHandler(pip.RequestHandler):,

class TestHandler(pip.RequestHandler):, etc?

Here's where I'm trying to host:

usersignup.thehamburgercollection.com

UPDATE: I wasn't able to host this app on appspot.com (google cloud). I just could not figure out how to upload my files to the correct directory - the instructions weren't clear / youtube tutorials were out of date. I'll post a solution if / when I figure out how.

回答1:

Your question is really confusing, PIP is just a package manager, PIP is to python what NPM is to NodeJs. Deploying apps to Google Cloud is straightforward. First Install Google Cloud SDk and navigate to your application's root directory and run the command.

gcloud deploy
