Methods: { 

      loginSubmit (formName) { 
        the this $ refs [formName] .validate (the async (Valid) =>. {
           IF (Valid) { 
            const RES = the await the this $ http.post ( 'Login',. the this .form); 
            Data {const, Meta: {Message, code}} = res.data;
             IF (code 2000 === ) { 

              // Get token, the token value stored in localStorage 
              localStorage.setItem ( 'token' , data.token); 

              // Jump directly to the main page after authentication is successful 
              this $ router.push ({name: 'Home'. });
               // successful login prompt 
              this. $ message.success (Message) 
            } the else {
               the this $ message.warning (Message).

          } 
        }); 
      } 
    },

2, the background verification

class the LoginView (APIView): 
    authentication_classes = []   # landing page-free, the rest of the global configuration has 

    DEF POST (Self, Request, * args, ** kwargs): 

        RET = {
             " Data " : {},
             " Meta " : {
                 " code " : 2001 ,
                 " Message " : " user name or password error " 
            } 
        } 
        USER_OBJ = json.loads (STR (request._request.body, encoding = ' UTF8 ')) 
        Username = user_obj.get ( ' username ' ) 
        password = user_obj.get ( ' password ' )
         IF username and password: 
            obj = UserInfo.objects.filter ( 
                username = username, password = password) .first ()
             IF obj: 

                token = get_md5 (username)
                 # automatically go to check the database, if not create, or update token 
                UserToken.objects.update_or_create (the User = obj, Defaults = { ' token ': token})
  
                ret["data"]["username"] = username
                ret["data"]["password"] = password
                ret["data"]["token"] = token

                ret["meta"]["code"] = 2000
                ret["meta"]["message"] = "登陆成功"
            else:
                pass
        else:
            pass
        return HttpResponse(json.dumps(ret, ensure_ascii=False))
