微信js-sdk+JAVA实现“分享到朋友圈”和“发送给朋友”功能详解

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});

  wx.ready(function(){   //详细代码});

wx.error(function(res){});
