uniapp 使用微信jssdk 调起 地图，扫码，分享等功能
引入文件：
jweixin-module/lib/index.js
这个可以 随便找个目录 执行 npm install jweixin-module --save 就可以获得，然后从 node_modules 目录下找到 jweixin-module 目录复制到 components 目录下就可以了。或者直接下载

核心代码：
com.js
import jweixin from '@/components/jweixin-module/lib/index.js';
const apiUrl = '/api';
const siteUrl = 'http://10.10.34.116:8080';
const shareData = {
title: "分享标题",
desc: "分享描述",
link: "https://10.10.34.116:8080/h5",
imgUrl: 'https://10.10.34.116:8080/assets/images/share.png'
};
const openPage = function(path){
if (getCurrentPages().length > 9) {
uni.reLaunch({
url: path
})
} else {
uni.navigateTo({
url: path
});
}
}
const checkMobile = function(tel){
var phoneReg = tel.match(/^1[3-9]\d{9}$/);
if(phoneReg){
return 1;
}else{
return 0;
}
};
//判断是否在微信中
const isWechat = function() {
var ua = window.navigator.userAgent.toLowerCase();
if (ua.match(/micromessenger/i) == 'micromessenger') {
// console.log('是微信客户端')
return true;
} else {
// console.log('不是微信客户端')
return false;
}
};
//获取微信JSSDK授权
const getWxConfig = function(){
var that = this;
if (!that.isWechat()) {
uni.showToast({
title: '请在微信里操作',
icon: 'none'
});
return;
}
uni.request({
url: that.siteUrl+'/login/index',
header: {
'content-type': 'application/x-www-form-urlencoded'
},
data: {
do: 'jssdk',
url: window.location.href,//当前页面的域名
},
method: 'GET',
success: (res) => {
console.log('getWxConfig->',res.data);
jweixin.config({
debug: false,
appId: res.data.appId,
timestamp: res.data.timestamp,
nonceStr: res.data.nonceStr,
signature: res.data.signature,
jsApiList: [
'scanQRCode',
'checkJsApi',
'onMenuShareTimeline',
'onMenuShareAppMessage',
'openLocation'
]
})
jweixin.ready(function() {
// 用户检查接口权限用 比如 想用调起扫码功能 scanQRCode 这部分代码上线的时候需要屏蔽，否则老弹窗
jweixin.checkJsApi({
jsApiList: ['scanQRCode'],
success: function(res) {
// 如：{"checkResult":{"chooseImage":true},"errMsg":"checkJsApi:ok"}
}
});
//分享给朋友接口
jweixin.onMenuShareAppMessage(that.shareData);
//分享到朋友圈接口
jweixin.onMenuShareTimeline(that.shareData);
});
jweixin.error(function(res){
console.log(res,'接口验证失败');
});
}
});
};
export default {
apiUrl,
siteUrl,
openPage,
checkMobile,
formatDate,
isWechat,
shareData,
getWxConfig,
jweixin
}使用方法：
引入自定义类 com
import com from '@/common/com.js';
onLoad里 调用
com.getWxConfig();
调起分享 默认把分享封装到com类里了，当然也可以每个页面单独配置
注意 wx.onMenuShareAppMessage() 调用换成 com.jweixin.onMenuShareAppMessage()
var shareData = {
title: "分享标题",
desc: "分享描述",
link: "https://10.10.34.116:8080/h5",
imgUrl: 'https://10.10.34.116:8080/assets/images/share.png'
};
//分享给朋友接口
com.jweixin.onMenuShareAppMessage(shareData);
//分享到朋友圈接口
com.jweixin.onMenuShareTimeline(shareData);
调起扫码 wx.scanQRCode：
com.jweixin.scanQRCode({
// 默认为0，扫描结果由微信处理，1则直接返回扫描结果，
needResult: 1,
// 可以指定扫二维码还是一维码，默认二者都有
scanType: ["qrCode", "barCode"],
success: function(res) {
console.log(res);
if (res.errMsg == 'scanQRCode:ok') {
console.log('扫码结果：',res.resultStr);
}
}
});调起微信地图导航 wx.openLocation
openMap(lng, lat, name, place) {
com.jweixin.openLocation({
// 纬度，必须浮点数，范围为90 ~ -90
latitude: parseFloat(lat),
// 经度，必须浮点数，范围为180 ~ -180。
longitude: parseFloat(lng),
// 位置名
name: name,
// 地址详情说明
address: place ? place: '',
// 地图缩放级别,整型值,范围从1~28。默认为最大
scale: 15,
//国标02
type: 'gcj02',
// 在查看位置界面底部显示的超链接,可点击跳转
infoUrl: ''
})

Jssdk.php 封装好的类 放Tp站点更目录下 applictation/common/library/Jssdk.php 可以放别的位置，注意修改命名空间

}在controller里调用
引入类 use app\common\library\Jssdk;
调用：
$jssdk = new Jssdk("已认证服务号appId", "secret密钥");//登陆公众账号后台获取

echo(json_encode($signPackage));
exit();
