How to create an one-time web Service by python

This article mainly introduces python how to create a web service, the article is very detailed, has a certain reference value, interested friends must read it!

Create a disposable, fast, small web service

Sometimes we need to do some simple, basic RPC-like interaction between two machines or services. We want to use the B program to call a method in the A program in a simple way-sometimes on another machine. For internal use only.

I do not encourage the use of the methods described here in non-internal, one-off programming. We can use a protocol called XML-RPC (corresponding to this Python library) to do this.

Here is an example of using the SimpleXMLRPCServer module to build a fast, small file reading server:

From SimpleXMLRPCServer import SimpleXMLRPCServer def file_reader (file_name): with open (file_name, r) as f: return f.read () server = SimpleXMLRPCServer ((localhost, 8000)) server.register_introspection_functions () server.register_function (file_reader) server.serve_forever ()

Client

Import xmlrpclibproxy = xmlrpclib.ServerProxy (http://localhost:8000/) proxy.file_reader (/ tmp/secret.txt)

This gives us a remote file reading tool with no external dependencies and only a few lines of code (of course, there are no security measures, so you can only do this at home).
