问题
So many web applications these days run on their own microservers, it can be hard to implement them on shared hosting platforms. The apps listen on a dedicated port you can customize or reverse proxy, but shared hosting usually only has 80 and 443 open.
Just as an example, the handy web-based editor ICEcoder is a PHP application, so you just drop the files in a directory and away you go. However, the Cloud9 editor runs its own server. You can customize the port, but again, you cant run the reverse proxy.
I had the idea of using a PHP or Python CGI script as an intermediary. Something like:
www.mydomain/mydirectory/middleman.py
from BaseHTTPServer import BaseHTTPRequestHandler
import urlparse, json
# hpyothetical apache api
import apache
parsed_path = urlparse.urlparse(self.path)
response = apache(url=parsed_path, port=8080)
sendStuffBack(response)
Would this be possible with Apache? How would I implement it?
Edit: Here is what I did based on @grawity's answer.
helloflask.py
#!/usr/bin/env python
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
middle.py
#!/usr/bin/env python
print ("Content-Type: text/html")
print()
import requests
#response = requests.get("http://localhost:5000")
response = requests.get("http://localhost:8888/token=8a387fe88d662e2568f9b8ec2398191452492e7184536670")
print(response.text)
回答1:
Your Python project is a reverse proxy, and the API you're looking for is just ordinary HTTP. (After all, that's how web browsers interact with Apache already...)
To make HTTP requests, you need a client like urllib or requests:
import requests
response = requests.get("http://" + apache_host + ":8080/" + parsed_path)
By default, all your apps and microservers will think that all clients come from localhost. If that's a problem, see if your apps accept the X-Forwarded-For header. (If they do, include it in all your requests.)
