Detailed graphic and text explanation of how to handle cross-domain request error issues in Python's bottle framework
This article mainly introduces the bottle framework of python How to deal with cross-domain request error reporting. Friends in need can refer to it
Using python When developing the bottle framework, when the front-end uses ajax for cross-domain access, the js code always fails to enter success, but enters error, and the returned status is 200. It is normal to access the url directly in the browser. After pressing F12 in the browser, you will find the following error message
XMLHttpRequest cannot load http://192.168.0.118:8081/get_mobile_number/? id=1. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
If you query errors through search engines, you will find that almost all the answers you find are cross-domain problems. You only need to add the following to the code of the main file. Many solutions on foreign websites explain this
@hook('after_request')
def enable_cors():
response.headers['Access-Control-Allow-Origin'] = '*'In fact, after adding according to the found solution, an error still occurred. Looking at the http header output by the browser, we did not see the Access-Control-Allow-Origin:* we just added, as shown below:
Through DEBUG, enter the bottle source code to view
I have tested that this problem exists in the bottle framework corresponding to python2 and python3 For this problem, we change it to:
class HTTPResponse(Response, BottleException):
def init(self, body='', status=None, headers=None, **more_headers):
super(HTTPResponse, self).init(body, status, headers, **more_headers)
def apply(self, response):
response._status_code = self._status_code
response._status_line = self._status_line
if self._headers:
if response._headers:
response._headers.update(self._headers)
else:
response._headers = self._headers
response._cookies = self._cookies
response.body = self.bodyWhen you run the code again, you can see that the ajax code is normal
