註冊企業微信,在應用與小程序欄目中,設置可信域名,配置公衆號菜單。可信域名不得不說下,在最初開發時,認爲設置並驗證後,微信認證接口會實現跨域請求,其實並無。因此全在H5端還得配合服務端完成票據獲取等操做。javascript
//author herbert QQ:464884492 getAccessToken() { // 判斷是否緩存有 return new Promise((resolve, reject) => { var access_token = localStorage.getItem("accessToken"); var expires = localStorage.getItem("expires_accessToken"); if (expires > new Date().getTime() - 2000) { resolve(access_token); return; } let accessTokenUrl = 'https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=' + this.groupId + "&corpsecret=" + this.secretId; // fetch(accessTokenUrl, { method: "GET" }) fetch(this.porxyUrl, { method: "POST", body: JSON.stringify({ method: "GET", url: accessTokenUrl }) }).then(resp => { return resp.json() }).then(data => { if (data.errcode == 0) { //保存本次獲取的accessToken localStorage.setItem("accessToken", data.access_token); localStorage.setItem("expires_accessToken", new Date().getTime() + data.expires_in * 1000); resolve(data.access_token); } }).catch(data => { reject(); }) }); }, 複製代碼
使用上一步驟獲取到的access_token獲取ticket,接口地址https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=ACCESS_TOKEN H5不能直接訪問,須要服務端經過代理訪問html
//author herbert QQ:464884492 getTicket() { return new Promise((resolve, reject) => { var ticket = localStorage.getItem("ticket"); var expires = localStorage.getItem("expires_ticket"); if (expires > new Date().getTime() - 2000) { resolve(ticket); return; } let ticketUrl = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=" + localStorage.getItem("accessToken"); //fetch(ticketUrl, { method: "GET" }) fetch(this.porxyUrl, { method: "POST", body: JSON.stringify({ method: "GET", url: ticketUrl }) }).then(resp => { return resp.json() }).then(data => { if (data.errcode == 0) { //保存本次獲取的accessToken localStorage.setItem("ticket", data.ticket); localStorage.setItem("expires_ticket", new Date().getTime() + data.expires_in * 1000); resolve(data.ticket); } }).catch(data => { reject(); }) }); }, 複製代碼
//author herbert QQ:464884492 getSignature(timestamp, ticket) { let url = window.location.href.split("#")[0]; let jsapi_ticket = "jsapi_ticket=" + ticket + "&noncestr=" + timestamp + "×tamp=" + timestamp.substr(0, 10) + "&url=" + url; this.printStatuInfo("簽名原始信息:" + jsapi_ticket); let sha1Str = new jsSHA(decodeURIComponent(jsapi_ticket), "TEXT"); return sha1Str.getHash("SHA-1", "HEX"); } 複製代碼
//author herbert QQ:464884492 wx.config({ beta: true,// 必須這麼寫,不然wx.invoke調用形式的jsapi會有問題 debug: false, // 開啓調試模式,調用的全部api的返回值會在客戶端alert出來,若要查看傳入的參數,能夠在pc端打開,參數信息會經過log打出,僅在pc端時纔會打印。 appId: wxUtils.groupId, // 必填,企業微信的corpID timestamp: timestamp.substr(0, 10), // 必填,生成簽名的時間戳 nonceStr: timestamp, // 必填,生成簽名的隨機串 signature: sig,// 必填,簽名,見附錄1 jsApiList: ["scanQRCode"] // 必填,須要使用的JS接口列表,全部JS接口列表見附錄2 }); 複製代碼
//author herbert QQ:464884492 wx.scanQRCode({ desc: 'scanQRCode desc', needResult: 1, // 默認爲0,掃描結果由企業微信處理,1則直接返回掃描結果, scanType: ["qrCode", "barCode"], // 能夠指定掃二維碼仍是一維碼,默認兩者都有 success: function (res) { // 回調 wxUtils.printStatuInfo("掃描信息:" + JSON.stringify(res)); lblCostTime.innerText = "單次掃碼總共花費:【" + (new Date().getTime() - timeStar) + "】ms"; }, error: function (res) { if (res.errMsg.indexOf('function_not_exist') > 0) { alert('版本太低請升級') } } }); 複製代碼
H5集成微信JSSDK功能雖然簡單,可是該有的步驟一個都不能少。在最初開發中遇到了如下幾個問題:前端
