[Enterprise] by means of micro-channel JS-SDK, the page calls the phone system functions

[Overview] Enterprise micro-letter web developer, the ability to call native essential, so, how to use JS-SDK to achieve?

[Official document] https://work.weixin.qq.com/api/doc#10029/

【step】

step1: in full accordance with the manual operation can be as follows

step2: config in obtaining the required configuration data (supplement)

Reference API server configuration https://work.weixin.qq.com/api/doc#90000/90135/90664 and JS-SDK documentation https://work.weixin.qq.com/api/doc#90000/90136 / 90506 to obtain application signature

Reference herein can be directly used in a method PHP Demo (refer to Part I: https://blog.csdn.net/gzyh_tech/article/details/88565966 ):

Obtain configuration information such as signature and time stamp

 /**获取jsqpi**/
    $jsapiTicket=$api->JsApiTicketGet();
    $nonceStr=createNonceStr();
    $timestamp=time();
    $jsapi=$api->JsApiSignatureGet($jsapiTicket, $nonceStr, $timestamp, getUrl());

So write in the page js:

wx.config({
    beta: true,// 必须这么写，否则wx.invoke调用形式的jsapi会有问题
    debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
    appId: '<?php echo $config['CORP_ID']?>', // 必填，企业微信的corpID
    timestamp:'<?php echo $timestamp?>' , // 必填，生成签名的时间戳
    nonceStr: '<?php echo $nonceStr?>', // 必填，生成签名的随机串
    signature: '<?php echo $jsapi?>',// 必填，签名，见附录1
    jsApiList: ['scanQRCode'] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
});

This is configured, basic usage is as follows:

wx.ready(function () {
    //TODO： 执行和jsapi相关的初始化操作
    //二维码扫描
    $("#scan").on("click",function(){
    	wx.scanQRCode({
    	    desc: 'scanQRCode desc',
    	    needResult: 1, // 默认为0，扫描结果由企业微信处理，1则直接返回扫描结果，
    	    scanType: ["qrCode", "barCode"], // 可以指定扫二维码还是条形码（一维码），默认二者都有
    	    success: function(res) {
    	        // 回调resultStr&errMsg

    	    },
    	    error: function(res) {
    	        if (res.errMsg.indexOf('function_not_exist') > 0) {
    	            alert('版本过低请升级');
    	            return;
    	        }
    	        alert(res.errMsg)
    	    }
    	});
     })
});
