前幾天因爲項目所需要實現微信分享接口，在網上搜了一大堆，實現辦法大致分爲兩種，第一：在body之後加一個img標籤並且設置display:none,這種方法感覺不科學所以我沒有測試過。第二：使用微信的分享接口，但在網上也沒用找到完整的示例，還是自己折騰吧，請看下面。
第一步：
先登錄微信公衆平臺進入“公衆號設置”的“功能設置”裏填寫“JS接口安全域名”。
注：認證帳號纔有分享權限
第二步
創建一個demo.php文件和wxshare.js
demo.php
<?php
// 步驟1.設置appid和appsecret
$appid = 'wxd75a2b20d3a54752';
$appsecret = '9b32270f32874ea7a7427f88ff770777';
// 步驟2.生成簽名的隨機串
function nonceStr($length){
$str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';//62個字符
$strlen = 62;
while($length > $strlen){
$str .= $str;
$strlen += 62;
}
$str = str_shuffle($str);
return substr($str,0,$length);
}
// 步驟3.獲取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;
}
}
// 步驟4.獲取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;
// 步驟5.生成wx.config需要的參數
$surl = 'http://'.$_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;
}
?>

<html lang="en">

<meta charset="UTF-8">
<title>Share Demo</title>
</head>
<body>
</body>
// 步驟6.調用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 = "我是標題";
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 () {
}
});
// 分享給朋友
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 () {
}
});
// 微信到騰訊微博
wx.onMenuShareWeibo({
title: wstitle,
desc: wsdesc,
link: wslink,
imgUrl: wsimg,
success: function () {
alert('分享成功');
},
cancel: function () {
}
});
// 分享到QQ空間
wx.onMenuShareQZone({
title: wstitle,
desc: wsdesc,
link: wslink,
imgUrl: wsimg,
success: function () {
alert('分享成功');
},
cancel: function () {
}
});
});
大功告成！
