1、如何封装uniapp，并且如何使用uniapp的封装查看👉uniapp请求封装_uni-app-x 请求封装-CSDN博客​​​​​​​
2、声明一个请求记录的缓存，代码如下

// 存储请求记录
let requestRecords = {};
// 重复请求拦截时间（毫秒）
const INTERCEPT_DURATION = 2000;
const request = (url, data = {}, method = "GET", ContentType = "application/json") => {const requestObj = {data,url,time: Date.now(),};if (method !== "GET") {if (Object.keys(requestRecords).length == 0) {requestRecords = requestObj;} else {const s_url = requestRecords.url; // 请求地址const s_data = requestRecords.data; // 请求数据const s_time = requestRecords.time; // 请求时间if (s_data === requestObj.data &&requestObj.time - s_time < INTERCEPT_DURATION &&s_url === requestObj.url) {uni.showToast({title: "数据正在处理，请勿重复提交",icon: "none",duration: 2000,});return;}requestRecords = requestObj;}}return new Promise(function (resolve, reject) {let header = {};if (uni.getStorageSync("token")) {header = {"Content-Type": ContentType,Authorization: uni.getStorageSync("token"),};} else {header = {"Content-Type": ContentType,};}if (Object.keys(data).length && !data.showLoading) {uni.showLoading({title: "加载中",mask: true,});}console.log("请求参数", data, url);uni.request({url: BASE_URL + url,data,method,header,success: function (res) {console.log("res", res);if (res.data.code == 200) {resolve(res.data);} else if (res.data.code == 401) {uni.navigateTo({url: "/pages/login/login",});} else {if (Object.keys(res.data).length && !data.showLoading) {uni.showToast({title: res.data.msg,icon: "none",duration: 2000,});}reject(res);}},fail: function (err) {console.log("err", err);uni.getNetworkType({success: function (res) {console.log("当前网络状态:", res.networkType);if (res.networkType === "none") {console.log("当前无网络");uni.showToast({title: "当前网络不可用，请检查网络连接",icon: "none",});return;} else {uni.showToast({title: "加载失败，请稍后重试！",icon: "none",duration: 2000,});}},});reject(err);},complete: function () {console.log("结束");if (!data.showLoading) {uni.hideLoading();}},});});
};
