Facebook、Twitter登录及分享

使用Hello.js接入

使用Hello.js简化接入，facebook和twitter接入方法一样。

Hello.js（
http://adodson.com/hello.js/）是一个客户端JavaScript SDK，用于OAuth2认证Web服务以及请求它们的REST Api。

HelloJS标准化了路径，并响应常见的API，比如说Google Data Services、Facebook Graph以及Windows Live Connect。它们是模块，所以这个列表还在增长中。

// 初始化,配置应用id
hello.init({ 
    facebook: FACEBOOK_CLIENT_ID,
    windows: WINDOWS_CLIENT_ID
}, {redirect_uri:'redirect.html'})

// 登录
hello.on('auth.login', function(auth){
    // 登录成功后，获取用户信息（fb、tw的用户数据有区别）
    hello( auth.network ).api( '/me' ).then(function (res) {
        console.log(res)
    })
})

Facebook登录后获取的用户信息

{
  email: "XX@gmail.com",
  first_name: "XX",
  id: "123456",
  last_name: "XX",
  name: "XX",
  picture: "url",
  thumbnail: "url"
}

Twitter登录后获取的用户信息

触发分享：

<a href=http://www.toutiao.com/a7151959005928243742/"javascript:void(0)" @click="fbShare">facebook 分享</a>

fbShare () {
  let sharePath = '' // 分享出去之后别人打开的链接
  let title = '' // 分享标题
  window.open('https://www.facebook.com/sharer/sharer.php?u=' + encodeURIComponent(sharePath) + '&t=' + encodeURIComponent(title), '_blank', 'toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=600, height=450, top=100, left=350')
}

分享信息设置：

分享出去的样式包含图片，标题，简介

这些信息不是分享的时候设置的，是爬虫直接爬的分享链接页面head中预先设置好的分享信息，head配置如下

<meta property="og:locale" content="en-US">
<meta property="og:type" content="website">
<meta property="og:title" content="realme Holi Game">
<meta property="og:image" content="xx.jpg">
<meta property="og:description" content="hello world">
