实现H5纯静态页面分享到微信朋友圈带图片显示需要前提条件
1、微信公众号已成功认证
2、微信公众号中添加js安全域名
3、添加ip白名单（服务器外网ip）
前端部分HTML代码如下：
<?php // 步骤1.设置appid和appsecret $appid = 'wxbb446b55816eb32b'; //此处填写绑定的微信公众号的appid $appsecret = '9288201823b0beda333a9698f861d0a8'; //此处填写绑定的微信公众号的密钥id // 步骤2.生成签名的随机串 function nonceStr($length){ $str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJK1NGJBQRSTUVWXYZ';//随即串，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=$nonceStr×tamp=$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><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>微信页面转发分享到微信朋友圈带图文显示</title> <meta name='viewport' content='width=device-width, initial-scale=1.0, maximum-scale=1.0'/> <meta name="keywords" content="微信页面转发分享到微信朋友圈带图文显示"> <meta name="description" content="微信页面转发分享到微信朋友圈带图文显示"> </head> <body> <div class="swiper-container"> </div> <script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script> <script> 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: 'wxbb446b55816eb32b', // 必填，公众号的唯一标识 timestamp: "<?php echo $ws["timestamp"]; ?>", // 必填，生成签名的时间戳 nonceStr: '<?php echo $ws["nonceStr"]; ?>', // 必填，生成签名的随机串 signature: '<?php echo $ws["signature"]; ?>',// 必填，签名，见附录1 jsApiList: [ 'checkJsApi', 'onMenuShareTimeline', 'onMenuShareAppMessage', 'onMenuShareQQ', 'onMenuShareWeibo' ] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2 }); var wstitle = "微信分享接口示例预览"; //此处填写分享标题 var wsdesc = "这是一个微信分享接口示例预览页面，可以发送到微信端预览并转发给朋友或者分享朋友圈看看效果如何！"; //此处填写分享简介 var wslink = "<?php echo $surl; ?>"; //此处获取分享链接 var wsimg = "http://share.xiaomenshenvip.com/images/shares.jpg"; //此处获取分享缩略图 </script> <script src="js/wxshare.js"></script> </body> </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 () { } }); });
