Const Request = require ("/ utils/request"); / / Import module Request.post ("/ api/xcxWxLogin", {/ / call method code: res.code, encryptedData: resp.encryptedData, iv: resp.iv, shareId: share.shareId | | ", salesmanId: share.salesmanId | |", source: share.source | | "}) .then (res = > {/ / successful callback / / todo}) .catch (err = > {}); / / exception callback

Step 6: complete code for interceptor

Const apiHttp = "https://*****.com";const socketHttp =" wss://*.com/wss "; function fun (url, method, data, header) {data = data | | {}; header = header | | {}; let sessionId = wx.getStorageSync (" UserSessionId "); if (sessionId) {if (! header | |! header [" SESSIONID "]) {header [" SESSIONID "] = sessionId;}} wx.showNavigationBarLoading () Let promise = new Promise (function (resolve, reject) {wx.request ({url: apiHttp + url, header: header, data: data, method: method, success: function (res) {if (typeof res.data = = "object") {if (res.data.status) {if (res.data.status = =-200) {wx.showToast ({title: "to ensure that the most accurate service is provided to you Please exit application reauthorization ", icon:" none "}) Reject ("Please login again");} else if (res.data.status = =-201) {wx.showToast ({title: res.data.msg, icon: "none"}); setTimeout (function () {wx.navigateTo ({url: "/ pages/user/supplement/supplement"});}, 1000); reject (res.data.msg) } resolve (res);}, fail: reject, complete: function () {wx.hideNavigationBarLoading ();}});}); return promise;} function upload (url, name, filePath) {let header = {}; let sessionId = wx.getStorageSync ("UserSessionId"); / / take the information if (sessionId) {if (! header | |! header ["SESSIONID"]) {header ["SESSIONID"] = sessionId from the cache / add to the request header}} wx.showNavigationBarLoading (); let promise = new Promise (function (resolve, reject) {wx.uploadFile ({url: apiHttp + url, filePath: filePath, name: name, header: header, success: function (res) {resolve (res);}, fail: reject, complete: function () {wx.hideNavigationBarLoading ();}}); return promise } module.exports = {apiHttp: apiHttp,socketHttp: socketHttp, "get": function (url, data, header) {return fun (url, "GET", data, header);}, "post": function (url, data, header) {return fun (url, "POST", data, header);}, upload: function (url, name, filePath) {return upload (url, name, filePath);}} This is the end of the introduction on "how to encapsulate WeChat Mini Programs http interceptor".
