前几天因为项目所需要实现微信分享接口，在网上搜了一大堆，实现办法大致分为两种，第一：在body之后加一个img标签并且设置display:none,这种方法感觉不科学所以我没有测试过。第二：使用微信的分享接口，但在网上也没用找到完整的示例，还是自己折腾吧，请看下面。

第一步：

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”。
注：认证帐号才有分享权限

第二步

创建一个demo.php文件和wxshare.js

demo.php

<?php    // 步骤1.设置appid和appsecret    $appid = 'wxd75a2b20d3a54752';    $appsecret = '9b32270f32874ea7a7427f88ff770777';    // 步骤2.生成签名的随机串    function nonceStr($length){        $str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';//62个字符        $strlen = 62;        while($length > $strlen){        $str .= $str;        $strlen += 62;        }        $str = str_shuffle($str);        return substr($str,0,$length);    }    // 步骤3.获取access_token    $result = http_get('https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$appsecret);    $json = json_decode($result,true);    $access_token = $json['access_token'];    function http_get($url){        $oCurl = curl_init();        if(stripos($url,"https://")!==FALSE){            curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);            curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, FALSE);            curl_setopt($oCurl, CURLOPT_SSLVERSION, 1); //CURL_SSLVERSION_TLSv1        }        curl_setopt($oCurl, CURLOPT_URL, $url);        curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1 );        $sContent = curl_exec($oCurl);        $aStatus = curl_getinfo($oCurl);        curl_close($oCurl);        if(intval($aStatus["http_code"])==200){            return $sContent;        }else{            return false;        }    }    // 步骤4.获取ticket    $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$access_token";    $res = json_decode ( http_get ( $url ) );    $ticket = $res->ticket;    // 步骤5.生成wx.config需要的参数    $surl = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];    $ws = getWxConfig( $ticket,$surl,time(),nonceStr(16) );    function getWxConfig($jsapiTicket,$url,$timestamp,$nonceStr) {        $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";        $signature = sha1 ( $string );        $WxConfig["appId"] = $appid;        $WxConfig["nonceStr"] = $nonceStr;        $WxConfig["timestamp"] = $timestamp;        $WxConfig["url"] = $url;        $WxConfig["signature"] = $signature;        $WxConfig["rawString"] = $string;        return $WxConfig;    }?><!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title>Share Demo</title></head><body></body>// 步骤6.调用JS接口<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script><script>  wx.config({      debug: false,      appId: '<?php echo $ws["appId"]; ?>',      timestamp: '<?php echo $ws["timestamp"]; ?>',      nonceStr: '<?php echo $ws["nonceStr"]; ?>',      signature: '<?php echo $ws["signature"]; ?>',      jsApiList: [          'checkJsApi',          'onMenuShareTimeline',          'onMenuShareAppMessage',          'onMenuShareQQ',          'onMenuShareWeibo',          'onMenuShareQZone',      ]  });  var wstitle = "我是标题";  var wsdesc = "我是描述";  var wslink = "<?php echo $surl; ?>";  var wsimg = "http://fmwei.com/usr/uploads/2016/07/794257096.png";</script><script src="wxshare.js"></script></html>

wxshare.js

wx.ready(function () {    // 分享到朋友圈    wx.onMenuShareTimeline({        title: wstitle,        link: wslink,        imgUrl: wsimg,        success: function () {            alert('分享成功');        },        cancel: function () {        }    });    // 分享给朋友    wx.onMenuShareAppMessage({        title: wstitle,        desc: wsdesc,        link: wslink,        imgUrl: wsimg,        success: function () {          alert('分享成功');        },        cancel: function () {        }    });    // 分享到QQ    wx.onMenuShareQQ({        title: wstitle,        desc: wsdesc,        link: wslink,        imgUrl: wsimg,        success: function () {            alert('分享成功');        },        cancel: function () {        }    });    // 微信到腾讯微博    wx.onMenuShareWeibo({        title: wstitle,        desc: wsdesc,        link: wslink,        imgUrl: wsimg,        success: function () {            alert('分享成功');        },        cancel: function () {        }    });    // 分享到QQ空间    wx.onMenuShareQZone({        title: wstitle,        desc: wsdesc,        link: wslink,        imgUrl: wsimg,        success: function () {            alert('分享成功');        },        cancel: function () {        }    });});

大功告成！
