?main.js中引入

二、在App.vue文件中加载微信的sdk

<script>
	export default {
		globalData: {
			weixinObj: undefined,
		},
		onLaunch: function() {
			console.log('App Launch');
			
			//初始化页面时加载微信js-sdk
			if (uni.getSystemInfoSync().platform != 'ios') {
				getApp().globalData.weixinObj = jWeixin;
			} else {
				getApp().globalData.weixinObj = wx;
			}
		},
	}
</script>

将获取的的js-sdk放到全局变量中缓存

三、在要调用扫一扫的页面加载企业微信接口

<script>
	// import wx1 from 'weixin-js-sdk'
	// import sha1 from 'js-sha1'

	export default {
		data() {
			return {
				timestamp: '',
				nonceStr: '',
				ticket: '',
				corpid: '',
				url: '',
				signature: '',
				
			}
		},
		onShow() {
			console.log("刷新页面")
		},
		created() {
			//初始化页面时加载微信js-sdk
			const _this = this;
			this.$nextTick(function () {
				_this.scanCodeConfig();
			  });
			//setTimeout(_this.scanCodeConfig(), 5000);
		},

				}
				return pwd
			},

			/**
			 * 拼接签名字符串
			 * @param ticket 通过access_token获取的jsapi_ticket
			 * @param noncestr 自己生成的随机字符串
			 * @param timestamp 生成签名时的时间戳

			 */

			},

				for (i = 0; i < s.length; i += 16) {
					var o = m.slice(0);

参数说明:

timestamp?:时间戳

nonceStr:随机字符串

ticket:通过access_token获取的jsapi_ticket

corpid:企业微信的corpid,必须与当前登录的企业一致

agentid:企业微信的应用id

以上参数中corpid、agentid需要向企业微信官网注册

其他参数后端生成

四、参数生成方式


import cn.hutool.core.util.RandomUtil;
import cn.hutool.core.util.XmlUtil;
import cn.hutool.crypto.SecureUtil;
import cn.hutool.http.webservice.SoapClient;

public HashMap<String, String> getJsConfig() {

        // 生成时间戳
        String timestamp = String.valueOf(new Date().getTime());
        // 生成的随机字符串
        String nonceStr = RandomUtil.randomString(16);

        String ticket = getTicket();

        String corpid = wxCpProperties.getCorpId();
        //应用id
        String agentid = wxCpProperties.getAppConfigs().getAgentId().toString();

        String url = "http://testzhqk.anmining.com:19012/him/pages/him/inspection/dangerousList/index";

        StringBuffer jsapi_ticket = new StringBuffer()
                .append("jsapi_ticket=").append(ticket)
                .append("&noncestr=").append(nonceStr)
                .append("&timestamp=").append(timestamp)
                .append("&url=").append(url);
        String signature = SecureUtil.sha1(jsapi_ticket.toString());
        HashMap map = new HashMap();
        map.put("timestamp", timestamp);
        map.put("nonceStr", nonceStr);
        map.put("ticket", ticket);
        map.put("corpid", corpid);
        map.put("url", url);
        map.put("signature", signature);
        map.put("agentid", agentid);

        return map;
    }
