uniapp+axios请求的封装

因在用vue3.0时会导致无法引有buildFullPath和settle两个库。所简单处理这两个方法

// utils/request.ts文件代码如下

javascript">/***uniapp+axios请求的封装
**/import axios from 'axios'
import $config from "@/config/config"
import {getToken,removeToken} from "@/utils/auth"// create an axios instance
//创建axios实例
const service = axios.create({baseURL: process.env.NODE_ENV === 'development' ? $config.baseUrl.dev : $config.baseUrl.pro,withCredentials: true, // send cookies when cross-domain requeststimeout: $config.timeout,// request timeoutheaders:{'Content-Type':'application/json;charset=utf-8'}
})//响应请求
service.interceptors.request.use(config => {if (config.headers.auth) { // 判断请求是否需要认证if(getToken()) config.headers['Authorization'] ='Authorization '+getToken();}return config},error => {return Promise.reject(error)}
)//响应拦截器
service.interceptors.response.use(({config,data}) => {console.log(data)if (data.code === 'A0230') { // token过期if(getToken()){uni.showToast({icon:"loading",title: '会话已过期，重新获取',success() {removeToken() //删除Tokenconsole.log('失败处理')}})}}},error => {const {code,msg} = error.response.dataif (code === 'A0230') { // token过期if(getToken()){uni.showToast({icon:"loading",title: '会话已过期，重新获取',success() {removeToken() //删除Tokenconsole.log('失败处理')}})}} else {uni.showToast({title: msg,icon: 'none'});return Promise.reject(new Error(msg || 'Errors'))}}
)//自己定义个适配器,用来适配uniapp的语法
service.defaults.adapter = function(config) {return new Promise((resolve, reject) => {//if(typeof config.data==="string") data=JSON.parse(config.data) //TODO GET会变成stringuni.request({method: config.method.toUpperCase(),url: combineURLs(buildFullPath(config.baseURL,config.url), config.params, config.paramsSerializer),header: {...config.headers},data:config.data,complete:(response)=>{response = {data: response.data,status: response.statusCode,errMsg: response.errMsg,header: response.header,config: config.data};settle(resolve, reject, response);}})})
}function buildFullPath(baseURL, requestedURL) {console.log(buildURL(requestedURL));if (baseURL && !buildURL(requestedURL)) {return combineURLs(baseURL, requestedURL);}return requestedURL;
}function buildURL(url) {// A URL is considered absolute if it begins with "<scheme>://" or "//" (protocol-relative URL).// RFC 3986 defines scheme name as a sequence of characters beginning with a letter and followed// by any combination of letters, digits, plus, period, or hyphen.return /^([a-z][a-z\d+\-.]*:)?\/\//i.test(url);
}function combineURLs(baseURL, relativeURL) {return relativeURL? baseURL.replace(/\/+$/, '') + '/' + relativeURL.replace(/^\/+/, ''): baseURL;
}function settle(resolve, reject, response) {let validateStatus = response.config.validateStatus;if (!response.status || !validateStatus || validateStatus(response.status)) {resolve(response);} else {reject(createError('Request failed with status code ' + response.status,response.config,null,response.request,response));}
};export default service

使用封装的例子

//aip/auth.ts

javascript">/*** 用户**/
import request from '@/utils/request'/*** 反馈信息* @param {*} type * @param {*} contact_mobile * @param {*} content * @param {*} images */
export function getBanner(data)  {return request({url:`/index/banner`,method: 'POST',data:data,headers: {'auth': true// 需要认证，通过}})
}
