H5网页实现微信分享，分享朋友圈功能，网上的代码基本上都过期了，特基于最新的jweixin-1.6.0版本的微信分享实现，以作备忘。

**目 录**

1.微信分享文档及配置

1.1微信分享官网文档

1.2 appid对应的公众号是否有分享接口权限

1.3设置白名单和绑定域名

2 代码实现

2.1后端Java代码

2.2前端代码

2.1 idea完整项目下载

3.常见问题及解决方法

3.1wx.config初始化失败

3.2分享接口没有权限

--------------------

# 1.微信分享文档及配置 #

## 1.1微信分享官网文档 ##

地址[https://developers.weixin.qq.com/doc/offiaccount/OA\_Web\_Apps/JS-SDK.html\#3][https_developers.weixin.qq.com_doc_offiaccount_OA_Web_Apps_JS-SDK.html_3]

需要注意一下，即将废弃接口，建议不要再调用了。

## 1.2 appid对应的公众号是否有分享接口权限 ##

登录公众号后，接口状态为已获得，表示有权限。如下图

##  1.3设置白名单和绑定域名 ##

分享的服务器外网ip地址，需要添加到白名单中，如下图

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”。

备注：登录后可在“开发者中心”查看对应的接口权限。

# 3.常见问题及解决方法 #

## 3.1wx.config初始化失败 ##

情况有很多种，主要如下：

1.Java后台前面的url与分享的url不一致，需要完全一致。例如后台是http，分享地址是https

2.参数不对

## 3.2分享接口没有权限 ##

这错误有2种情况，1是参数不对；2是公众号中分享接口的状态为未获得。

有疑问，欢迎大家留言。
