想了解微信js-sdk+JAVA实现“分享到朋友圈”和“发送给朋友”功能详解的相关内容吗,在本文为您仔细讲解微信js-sdk实现“分享到朋友圈”和“发送给朋友”的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:微信js-sdk,微信开发分享到朋友圈和发送给朋友,下面大家一起来学习吧。

主要为以下实现步骤:

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

});

5.通过error接口处理失败验证

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

详细页面代码

<script> 
//微信分享朋友圈 
$(function(){ 
 /***用户点击分享到微信圈后加载接口接口*******/ 
  var url=window.location.href.split('#')[0]; 
   url = url.replace(/&/g, '%26');

另外项目用到的Sha1Util.java和MD5Util.java可以直接在平台下载。
