                        vm.msg = ''
                        vm.result = ''                        //验证地址
                        vm.loginUrl= 'http://xxx/'                        //查询地址
                        vm.apiUrl = 'http://yyy/'
                        vm.loginModel= {

                            password: '你的密码',                                    //    grant_type: 'password',                    }                    
                        //先获取 token                    
                 axios.post(vm.loginUrl,vm.loginModel)
                 .then(function(res){
                     sessionStorage.setItem('accessToken', res.data.token)                     //显示token值                 console.log(res.data.token);
                    })
                    .catch(function(err){

                        Authorization:'JWT ' + sessionStorage.getItem('accessToken')
                    }
                })
                 .then(function(res){                //     显示结果                    console.log(res.data);
