不限CMS使用的网站微信自定义分享代码

本文介绍了不限CMS使用的网站微信自定义分享代码，不仅DEDECMS可以使用，所有其他的CMS也都可以使用。有此需要的朋友可以看看，值得参考。

今天92建站小编给大家介绍一个微信自定义分享代码，不限系统，基本上所有网站都可以用到。一起来看看吧。

实现方法：

在网站根目录下新建js目录，放入以下2个文件

js/jssdk.php

js/share.js

jssdk.php 代码如下

<?php

$url = $_GET['url'];//2017-06-27

class JSSDK {

private $appId;

private $appSecret;

private $url;//2017-06-27

public function __construct($appId, $appSecret,$url) {

$this->appId = $appId;

$this->appSecret = $appSecret;

$this->url = $url;//2017-06-27

}

public function getSignPackage() {

$jsapiTicket = $this->getJsApiTicket();

// 注意 URL 一定要动态获取，不能 hardcode.

$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ||

$_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";

//$url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";//2017-06-27

$url =$this->url;//2017-06-27

$timestamp = time();

$nonceStr = $this->createNonceStr();

// 这里参数的顺序要按照 key 值 ASCII 码升序排序

$string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";

$signature = sha1($string);

$signPackage = array(

"appId"

=> $this->appId,

"nonceStr"  => $nonceStr,

"timestamp" => $timestamp,

"url"

=> $url,

"signature" => $signature,

"rawString" => $string

);

return $signPackage;

}

private function createNonceStr($length = 16) {

$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

$str = "";

for ($i = 0; $i < $length; $i++) {

$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);

}

return $str;

}

private function getJsApiTicket() {

// jsapi_ticket 应该全局存储与更新，以下代码以写入到文件中做示例

$data = json_decode(file_get_contents("jsapi_ticket.json"));

if ($data->expire_time < time()) {

$accessToken = $this->getAccessToken();

// 如果是企业号用以下 URL 获取 ticket

// $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken";

$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";

$res = json_decode($this->httpGet($url));

$ticket = $res->ticket;

if ($ticket) {

$data->expire_time = time() + 7000;

$data->jsapi_ticket = $ticket;

$fp = fopen("jsapi_ticket.json", "w");

fwrite($fp, json_encode($data));

fclose($fp);

}

} else {

$ticket = $data->jsapi_ticket;

}

return $ticket;

}

private function getAccessToken() {

// access_token 应该全局存储与更新，以下代码以写入到文件中做示例

$data = json_decode(file_get_contents("access_token.json"));

if ($data->expire_time < time()) {

// 如果是企业号用以下URL获取access_token

// $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";

$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret";

$res = json_decode($this->httpGet($url));

$access_token = $res->access_token;

if ($access_token) {

$data->expire_time = time() + 7000;

$data->access_token = $access_token;

$fp = fopen("access_token.json", "w");

fwrite($fp, json_encode($data));

fclose($fp);

}

} else {

$access_token = $data->access_token;

}

return $access_token;

}

private function httpGet($url) {

$curl = curl_init();

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

curl_setopt($curl, CURLOPT_TIMEOUT, 500);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true); //https

curl_setopt($curl, CURLOPT_URL, $url);

$res = curl_exec($curl);

curl_close($curl);

return $res;

}

}

$jssdk = new JSSDK("AAPID", "appSecret",$url);

$signPackage = $jssdk->GetSignPackage();

$tmp=json_encode(array ('appId'=>$signPackage["appId"],'timestamp'=>$signPackage["timestamp"],

'nonceStr'=>$signPackage["nonceStr"],'signature'=>$signPackage["signature"],'url'=>$signPackage["url"]));

$callback = $_GET['callback'];

echo $callback.'('.$tmp.')';

exit;

?>

share.js代码如下

url = location.href; $.ajax({

type: "get",

url: "../js/jssdk.php?url=" + url,

dataType: "jsonp",

jsonp: "callback",

jsonpCallback: "success_jsonpCallback",

success: function(data) {

wx.config({

appId: data.appId,

timestamp: data.timestamp,

nonceStr: data.nonceStr,

signature: data.signature,

jsApiList: ['chackJsApi', 'onMenuShareTimeline', 'onMenuShareAppMessage',

'onMenuShareQQ', 'onMenuShareWeibo', 'onMenuShareQZone']

});

},

error: function(data) {

alert("连接失败！");

} }); wx.ready(function() {

var shareData = {

title: title,

desc: desc,

link: url,

imgUrl: img,

success: function(res) {

//分享成功

},

cancel: function(res) {

alert('已取消分享');

}

};

wx.onMenuShareAppMessage(shareData);

wx.onMenuShareTimeline(shareData);

wx.onMenuShareQQ(shareData);

wx.onMenuShareWeibo(shareData);

wx.onMenuShareQZone(shareData); });

部署方式 页面底部添加如下代码

<script src="https://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script> <script src="https://你的域名/js/share.js"></script> <script> var url = '你的域名';//用户要分享的网址 var title  = '您的标题';//分享的标题 var img = '您的图片地址';//分享的图片 var desc = '您的描述信息';//分享的描述信息 </script>

这样就可以了。
