Step 1: Import JS file

<script src="//res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>

Step 2: Inject permission verification configuration through the config interface

	// 使用微信内置API都需要进入校验操作
	wx.config({
    
    
    	beta: true,// 必须这么写，否则wx.invoke调用形式的jsapi会有问题
   	 	debug: true, // 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: '', // 必填，企业微信的corpID
    	timestamp: , // 必填，生成签名的时间戳
    	nonceStr: '', // 必填，生成签名的随机串
    	signature: '',// 必填，签名，见 附录-JS-SDK使用权限签名算法
    	jsApiList: [] // 必填，需要使用的JS接口列表，凡是要调用的接口都需要传进来
	});

Calling the config API to obtain an encrypted signature requires encryption and encryption rules, see the official document for details

official document

url (the URL of the current web page, excluding # and its following parts) only removes the last part of the content after # / cannot be removed, the following is an error example, and the removal of post-validation failed

const link = location.href.split('#')[0]
const url = link.substring(0, link.length - 1)

The jsapi_ticket is valid for 7200 seconds and is obtained through access_token. Since the number of API calls to obtain jsapi_ticket is very limited (one enterprise can obtain up to 400 calls within one hour, and a single application cannot exceed 100 calls), frequent refreshing of jsapi_ticket will lead to limited API calls and affect their own business. Developers must The service caches jsapi_ticket globally.

Step 3: Handle successful verification through the ready interface

	wx.ready(function(){
    
    
    	// config信息验证后会执行ready方法，所有接口调用都必须在config接口获得结果之后，config是一个客	户端的异步操作，所以如果需要在页面加载时就调用相关接口，则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口，则可以直接调用，不需要放在ready函数中。
	});

Step 4: Handle failed verification through the error interface

	wx.error(function(res){
    
    
    	// config信息验证失败会执行error函数，如签名过期导致验证失败，具体错误信息可以打开config的debug模式查看，也可以在返回的res参数中查看，对于SPA可以在这里更新签名。
	});

Error information can be queried through the official error query tool

Step 5: Call WeChat API

wx.scanQRCode({
    
    
    desc: 'scanQRCode desc',
    needResult: 0, // 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) {
    
    
        // resultStr为JOSN类型
		var result = res.resultStr;//当needResult为1时返回处理结果
    },
    error: function(res) {
    
    
        if (res.errMsg.indexOf('function_not_exist') > 0) {
    
    
            alert('版本过低请升级')
        }
    }
});
