版本号
"vue": "^3.2.45",
"axios": "^1.4.0",
"axios-miniprogram-adapter": "^0.3.5",
安装axios及axios适配器,适配小程序
yarn add axios axios-miniprogram-adapter
使用axios
在
utils
创建utils/request.ts
文件
TypeScript
import axios from "axios"
import type { AxiosAdapter, AxiosInstance, AxiosPromise, AxiosRequestConfig, AxiosResponse } from "axios";
import mpAdapter from "axios-miniprogram-adapter";
axios.defaults.adapter = mpAdapter as any
interface Result<T = any> {
code: number | string;
msg: string;
data: T;
};
/* declare module 'axios' {
//如遇到request()方法里的retuen报类型错误,放开这段注释采用这种形式定义返回类型,将上方的Result接口注释
interface AxiosResponse<T = any> {
code: number | string;
msg: string;
data: T;
}
type Result<T = any> = AxiosResponse<T>;
} */
// 导出Request类,可以用来自定义传递配置来创建实例
class HttpRequest {
baseURL: string;
timeout: number;
constructor() {
this.baseURL = import.meta.env.VITE_BASE_URL;
this.timeout = 60000
}
request<T = any>(options: AxiosRequestConfig): Promise<Result<T>> {
// axios 实例
const instance: AxiosInstance = axios.create()
this.setInterceptors(instance)
const opts = this.mergeOptions(options)
return instance(opts)
}
get<T = any>(url: string, data?: any, outHeaders = {}): Promise<Result<T>> {
return this.request<T>({
method: 'get',
url,
params: { ...data }, // get参数可以直接展开
headers: {}
})
}
post<T = any>(url: string, body = {}, outHeaders = {}): Promise<Result<T>> {
let data = {
body,
header: {}
}
return this.request<T>({
method: 'post',
url,
data, // post要求必须传入data属性
})
}
mergeOptions(options: AxiosRequestConfig) {
//console.log('合并参数', options)
return {
baseURL: this.baseURL,
timeout: this.timeout,
...options
}
}
// 设置拦截器
setInterceptors(instance: AxiosInstance) {
// 请求拦截器
instance.interceptors.request.use((config) => {
uni.showLoading({
title: '加载中...',
mask: true
});
// 一般会请求拦截里面加token,用于后端的验证
/* const token = localStorage.getItem("token")
config!.headers!.Authorization = token
config.headers = Object.assign(config.headers, { ...config.headers, token }); */
return config
},
(err: any) => {
console.log(err, '请求拦截报错');
uni.hideLoading();
return Promise.reject(err);
})
// 响应拦截器
instance.interceptors.response.use(
(res: AxiosResponse) => {
//res为AxiosResponse类型,含有config\data\headers\request\status\statusText属性
console.log(res);
uni.hideLoading();
let { status, data } = res
if (status === 200) {
// return Promise.resolve(data)
return data
} else {
}
},
err => {
console.log('axios报错', err)
uni.hideLoading(); // 立即关闭加载框
return Promise.reject(err)
}
)
}
}
// 默认导出Request实例
export default new HttpRequest()
在
src
目录下创建src/api/config
文件夹
config文件夹中创建home.ts文件,首页的接口都放在里面统一管理
TypeScript
export default {
getHomeData: "/frontpage",
}
和
config
文件夹同级创建home.ts文件,统一管理请求接口的方法
TypeScript
import axios from '@/utils/request'
import home from './config/home'
export const getHomeData = () => axios.get(home.getHomeData) //无参使用方式
export const getHomeData = options:any => axios.get(home.getHomeData, options) //有参使用方式 options参数可以自行统一定义
在页面中使用,home.vue文件
html
<template>
<view class="content">
</view>
</template>
<script setup lang="ts">
import { onMounted, ref } from 'vue'
import { getHomeData } from '@/api/home'
onMounted(() => {
homeData()
})
const homeData = async () => {
const { data } = await getHomeData()
console.log(data, '首页数据+++++++++')
}
</script>
<style lang="scss"></style>
