uniapp 封装axios

注：axios必须低于0.26.0，重中之重

重点：封装axios的适配器adapter

1.安装axios

npm install axios@0.26.0

创建api文件夹

2.新建adapter.js文件

import settle from "axios/lib/core/settle"
import buildURL from "axios/lib/helpers/buildURL"
import buildFullPath from "axios/lib/core/buildFullPath"const adapter = function(config) {return new Promise((resolve, reject) => {let fullurl = buildFullPath(config.baseURL, config.url)uni.request({method: config.method.toUpperCase(),url: buildURL(fullurl, config.params, config.paramsSerializer),header: config.headers,data: config.data,dataType: config.dataType,responseType: config.responseType,sslVerify: config.sslVerify,complete: function complete(response) {response = {data: response.data,status: response.statusCode,errMsg: response.errMsg,header: response.header,config: config};settle(resolve, reject, response);}})})
}export default adapter

3.新建index.js文件

import axios from "axios";
import adapter from "./adapter"// 存储请求中的接口
const pending = [];
const instance = axios.create({timeout: 60000,headers: {"Content-Type": "application/json",},
});
// 封装的是适配器
instance.defaults.adapter = adapter;
/** 增加请求拦截器*/
instance.interceptors.request.use(config => {},(error) => {/}
);
/** 增加响应拦截器*/
instance.interceptors.response.use((response) => {},(error) => {}
);export default instance;export const request = url => {return {};
};
