相关主题：PHP开发
因为项目所需要实现微信分享接口，这里是PHP调用微信公众号接口示例：
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
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=$nonceStr×tamp=$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;

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！
