1.注册微信公众号，配置网站域名，获取密钥和appId

2.安装JSSDK，并且导入项目中

npm install weixin-js-sdk --save

import wx from 'weixin-js-sdk';

3.获取access_token，再通过access_token获取ticket

async getAccessToken() {
				const data = {
					appid: "",
					grant_type: "client_credential",
					secret: ''
				}
				const res = await getAccess_token(data);
				if (res && res.length > 0) {
					return res[1].data?.access_token;
				}

			},

	async getTicket() {
				const data = {
					access_token: await this.getAccessToken(),
					type: "jsapi"
				}
				const res = await getTicket(data);
				if (res && res.length > 0) {
					return res[1].data?.ticket
				}
			},

4.配置SDK参数

async configWechatSDK() {
				const timestamp = Date.now();
				const nonceStr = JSON.stringify(new Date());
				const signature = await this.getTicket();
				const config = {
					debug: true,
					appId: '',
					timestamp,
					nonceStr,
					signature,
					jsApiList: ['openLocation'] // 需要的JS接口列表   
				}
				wx.config(config);
				wx.ready(() => {
					console.log("jssdk加载成功！")

				})
				wx.error(() => {
					console.log("jssdk加载失败！")
				})
			},
