VUE封装Axios请求

        //  封装请求级联数据
            queryAxios(lvl, name) {
                return new Promise(async(resolve, reject) => {
                let res = await  this.axios({
                        url: 'getTWO',
                        method: 'get',
                        params: {
                            LVL: lvl,
                            name: name
                        }
                    }).catch(err => {
                        reject(err)
                    })
                    resolve(res)
                })
            },

其他方法调用,减少相同写多次一样的请求

      async getCity() {
                let dataCity = await this.queryAxios(2, '湖南省')
                 console.log(dataCity)
            }
