php完成微信sdk分享接口

软件开发工具包(外语首字母缩写:SDK、外语全称:Software Development Kit)一般都是一些软件工程师为特定的软件包、软件框架、硬件平台、操作系统等建立应用软件时的开发工具的集合。本文主要和大家分享php实现微信sdk分享接口，希望能帮助到大家。

     * 这里为威狮码的公众号的openid和appsecret,如果配置到其他的子商家会出现需要关注威狮码公众号,
     * 则需要获取数据库的vender表里面的openid和appsecret

前端代码

jQuery.post("/xxx", {"url": encodeURIComponent(window.location.href.split('#')[0]),"t": new Date().getTime()}, function (result) {
    if (result.errno != 0) {
        alert("您当前的网络不稳定请稍后再试！");
        return;
    }
    var shareUrl = result.data.url;
    wx.config({
        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: 'xxx', // 必填，公众号的唯一标识
        timestamp: result.data.timestamp, // 必填，生成签名的时间戳
        nonceStr: result.data.nonceStr, // 必填，生成签名的随机串
        signature: result.data.signature,// 必填，签名，见附录1
        jsApiList: ['onMenuShareAppMessage','onMenuShareTimeline','onMenuShareQQ','onMenuShareWeibo','onMenuShareQZone'] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
