Cross-domain access to Python web development under the "Python" bottle framework

The previous article introduced the Python Application bottle Lightweight framework for Web development, this time introducing cross-domain access issues in the bottle framework.

When the current cross-domain access, the data cannot be obtained from the background, which means that cross-domain access failed.

The solution is as follows:

Define a function code in the program as follows:

#!/usr/bin/python#-*-conding:utf-8-*-from bottle Import * #decoratordef Allow_cross_domain (FN):    def _enable_cors (*args, **kwargs):        #set Cross headers        response.headers[' access-control-allow-origin '] = ' * '        response.headers[' access-control-allow-methods ' = ' get,post,put,options '        allow_headers = ' Referer, Accept, Origin, user-agent '        response.headers[' access-control-allow-headers '] = allow_headers             If Bottle.request.method! = ' OPTIONS ':            # actual request; Reply with the actual response            return fn (*args, **kwargs) 
   return _enable_cors@route ('/helloworld/:yourwords ', methods=[' GET ', ' POST ']) @allow_cross_domain                                              # Add the defined function def hello (yourwords) here: Return ' Hello World '. ' + yourwordsrun (host= ' 0.0.0.0 ', port=8080)

As shown in the code above, the cross-domain access problem can be resolved at each invocation, plus the function for cross-domain.

We hope to help you. Thank you.
