What are the steps to set the request through axios global request parameters and return the interceptor?

axios.interceptors.request.use(
		config => {
			var xtoken = getXtoken()
			if(xtoken != null){
				config.headers['X-Token'] = xtoken
			}
			if(config.method=='post'){
				config.data = {
					...config.data,
					_t: Date.parse(new Date())/1000,
				}
			}else if(config.method=='get'){
				config.params = {
					_t: Date.parse(new Date())/1000,
					...config.params
				}
			}
			return config
		},function(error){
			return Promise.reject(error)
		}
	)
axios.interceptors.response.use(function (response) {
	// token 已过期，重定向到登录页面
	if (response.data.code == 4){
		localStorage.clear()
		router.replace({
            path: '/signin',
            query: {redirect: router.currentRoute.fullPath}
          })
	}
	return response
}, function (error) {
	// Do something with response error
	return Promise.reject(error)
})
