1、封装http.ts
javascript
//utils--->http.ts
/**
* 添加拦截器
* 拦截request请求
* 拦截uploadFile文件上传
*
* TODO
* 1、非http开头需要拼接地址
* 2、请求超时
* 3、添加小程序端请求头标识
* 4、添加token请求头标识
*/
import { useMemberStore } from '@/stores/index'
const memberStore = useMemberStore()
//实际项目种的baseUrl是根据环境变量来获取的
const baseUrl = 'https://xx/xx/xx'
const httpInterceptor = {
invoke(args: UniApp.RequestOptions) {
// 拦截前触发,拼接url
if (!args.url.startsWith('http')) {
args.url = baseUrl + args.url
}
//请求超时时间,默认60s
args.timeout = 10000
//添加小程序请求头标志
args.header = {
...args.header,
'source-client': 'miniapp',
}
//添加token
const token = memberStore.profile?.token
if (token) {
args.header.Authorization = token
}
},
}
// 添加拦截器
uni.addInterceptor('request', httpInterceptor)
uni.addInterceptor('uploadFile', httpInterceptor)
//定义泛型,接口返回的数据结构
interface Data<T> {
code: string
msg: string
result: T
}
export const http = <T>(options: UniApp.RequestOptions) => {
return new Promise<Data<T>>((resolve, reject) => {
uni.request({
...options,
// 响应成功
success(res) {
if (res.statusCode >= 200 && res.statusCode < 300) {
resolve(res.data as Data<T>)
} else if (res.statusCode === 401) {
//401错误,清理用户信息,跳转登录页,调用reject
memberStore.clearProfile()
uni.navigateTo({ url: '/pages/login/login' })
reject(res)
} else {
//通用错误,调用reject
uni.showToast({
title: (res.data as Data<T>).msg || '请求错误',
icon: 'none',
})
reject(res)
}
},
fail(err) {
//响应失败,网络错误,调用reject
uni.showToast({
title: '网络错误,换个网络试试',
icon: 'none',
})
reject(err)
},
})
})
}
2、封装api
javascript
//api--->my.ts
import { http } from '@/utils/http'
export const getBanner = (data: any) => {
return http<string[]>({
url: '/xx/xx',
method: 'GET',
data: data,
})
}
3、使用封装好的api
javascript
<script setup lang="ts">
import { getBanner } from '@/api/my'
const getData = async () => {
const res = await getBanner({})
console.log(1111, res)
}
</script>
