With this module has beed loaded, then we can "gain" any module on the fly. Because the python scripts can do almost anything that the C language can do, so with this module's power, we can throw upgrading away from now on.
1 - Put a python script on the website, I had put one at: http://oeb1qxnpc.bkt.clouddn.com/hello.py, the file's content is:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
# @author: zig([email protected])
print("hello, pygain")2 - Load this module from a local test script file "test.py", then "gain" the remote "hello.py":
import pygain
pygain.gain("hello", "http://oeb1qxnpc.bkt.clouddn.com", ["py"])
import hello3 - Execute the test script(tested from python2.6.6 to python3.5.2):
> python test.pyif everything is fine, then we can see the "hello, pygain" was printed out
"gain" remote script one by one is inefficient, so we can zip scripts together, let's do it
1 - Put a zip that contains some scripts, I had put one at: http://oeb1qxnpc.bkt.clouddn.com/demo.zip, the zip's content is:
demo.zip
/- init.py
/- hello.py
/- hello2.py
2 - Load this module from a local test script file "test.py", then "gain" the remote "demo.zip":
import pygain
pygain.gain("demo", "http://oeb1qxnpc.bkt.clouddn.com", ["zip", "py"])
import demo.hello23 - Execute the test script(tested from python2.6.6 to python3.5.2)
> python test.pyif everything is fine, then we can see the "hello, pygain" was printed out
4 - But we need only fetch the zip file, the scripts that embeded in the zip will import directly from the zip file.
Because of some special situation, we provider some keyword arguments, we can pass it on as below:
pygain.gain("demo", "http://zagzig.me/pygain/demo/v1", ["zip", "py"],
httpheaders={"Referer": "xxx"}, zippw="guesswhat")-
httpheaders: when we fetch the remote file, we can pass on some http headers
-
zippw: the remote zip file can be encrypted, so pass this password to decrypt&load the remote zip module
pip install pygain
