ajax403错误,Django jquery ajax 403 error

See the HTTP/1.1 Status Code Definitions. "403" is the status code "Forbidden". This is an error being thrown on the server side of your $.ajax request, not the client side (i.e. your code is making a request, but the response from the server is an error message).

The document indicates servers should respond with that error only in specific situations:

The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.

Typically, an error of this sort means that whatever user you're logged in as does not have access to the URL you are requesting. Often, this indicates that the only error in your code is the URL you are making the request to or the ordering of a sequence of calls (e.g. you are trying to request data before logging in). Less commonly, some web servers and web applications are configured to respond with 403 error codes instead of 404 (not found) error codes for all "invalid" requests to avoid leaking information about what files do/don't exist on the server.
