# 与服务端交互
# 前端请求流程
在 admin-element-vue-vite-ts 中，一个完整的前端 UI 交互到服务端处理流程是这样的：
- UI 组件交互操作；
- 调用统一管理的
store.tsStoreModel；(此步可以省略，可以直接进行下步) store.ts调用service.tsapi 请求函数；- 使用封装的
@/utils/request.ts发送请求； - 获取服务端返回；
- 更新 data；
# request.ts
@/utils/request.ts 是基于 Axios (opens new window) 的封装，便于统一处理 POST，GET 等请求参数，请求头，以及错误提示信息等。具体可以参看 @/utils/request.ts (opens new window)。
它封装了全局 request拦截器、response拦截器、统一的错误处理、统一做了超时处理、baseURL设置等。
# 一个表单提交例子：
// @/views/pagesample/form/basic/service.ts
import request from '@/utils/request';
import { FormDataType } from './data.d';
export async function createData(params: FormDataType): Promise<any> {
return request({
url: '/pages/form',
method: 'POST',
data: params,
});
}
