微信js-sdk实现分享到朋友圈

微信接口文档地址：https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141115&token=&lang=zh_CN
实现步骤：
1.绑定域名
先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。（特别提示不需要加上http或者https,吃过亏）
2.页面引入js文件
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script src="https://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
3.通过config接口注入权限验证配置
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: '', // 必填，公众号的唯一标识
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1
jsApiList: [] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
});
4.通过ready接口处理成功验证
wx.ready(function(){
//详细代码
});
通过error接口处理失败验证
wx.error(function(res){});
