微信JSAPI 微信内置JSAPI 2015年1月官方正式API接口，分享完整实例
2015年1月30日，今天发现一些JS分享问题，一直很费解，通过查看原版开发手册，发现了根据原版的JSSDK进行修改补充。
主要用于微信浏览器分享朋友圈，转发好友等功能。

  1. HTML通过微信，分享朋友圈出发此JSAPI 

<?php
require_once "jssdk.php";
$jssdk = new JSSDK("yourAppID", "yourAppSecret");
$signPackage = $jssdk->GetSignPackage();
?>
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title></title>
</head>
<body>
   
</body>
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
  // 注意：所有的JS接口只能在公众号绑定的域名下调用，公众号开发者需要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”。 
  // 如果发现在 Android 不能分享自定义内容，请到官网下载最新的包覆盖安装，Android 自定义分享接口需升级至 6.0.2.58 版本及以上。
  // 完整 JS-SDK 文档地址：http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
  wx.config({
    appId: '<?php echo $signPackage["appId"];?>',
    timestamp: <?php echo $signPackage["timestamp"];?>,
    nonceStr: '<?php echo $signPackage["nonceStr"];?>',
    signature: '<?php echo $signPackage["signature"];?>',
    jsApiList: [
      // 所有要调用的 API 都要加到这个列表中
    ]
  });
  wx.ready(function () {
    // 在这里调用 API
 
    wx.onMenuShareTimeline({
        title: '', // 分享标题
        link: '', // 分享链接
        imgUrl: '', // 分享图标
        success: function () { 
            // 用户确认分享后执行的回调函数
        },
        cancel: function () { 
            // 用户取消分享后执行的回调函数
        }
    });
     
    wx.onMenuShareAppMessage({
        title: '', // 分享标题
        desc: '', // 分享描述
        link: '', // 分享链接
        imgUrl: '', // 分享图标
        type: '', // 分享类型,music、video或link，不填默认为link
        dataUrl: '', // 如果type是music或video，则要提供数据链接，默认为空
        success: function () { 
            // 用户确认分享后执行的回调函数
        },
        cancel: function () { 
            // 用户取消分享后执行的回调函数
        }
    });
     
    wx.onMenuShareQQ({
        title: '', // 分享标题
        desc: '', // 分享描述
        link: '', // 分享链接
        imgUrl: '', // 分享图标
        success: function () { 
           // 用户确认分享后执行的回调函数
        },
        cancel: function () { 
           // 用户取消分享后执行的回调函数
        }
    });
 
    wx.onMenuShareWeibo({
        title: '', // 分享标题
        desc: '', // 分享描述
        link: '', // 分享链接
        imgUrl: '', // 分享图标
        success: function () { 
           // 用户确认分享后执行的回调函数
        },
        cancel: function () { 
            // 用户取消分享后执行的回调函数
        }
    });
 
  });
</script>
</html>

2.微信公众平台多用户分享JSSDK 

<?php
class JSSDK {
  private $appId;
  private $appSecret;
  public $User_ID;
 
  public function __construct($appId, $appSecret, $User_ID = 1) {
    $this->appId = $appId;
    $this->appSecret = $appSecret;
    $this->User_ID = $User_ID;
  }
   
  public function Ext_FileSystem(){
    if(!file_exists("jSon_file/jsapi_ticket_".$this->User_ID.".json")){
        touch("jSon_file/jsapi_ticket_".$this->User_ID.".json");
        chmod("jSon_file/jsapi_ticket_".$this->User_ID.".json",0755);
    }
     
    if(!file_exists("jSon_file/access_token_".$this->User_ID.".json")){
        touch("jSon_file/access_token_".$this->User_ID.".json");
        chmod("jSon_file/access_token_".$this->User_ID.".json",0755);
    }
  }
   
  public function getSignPackage() {
    $this->Ext_FileSystem();
    $jsapiTicket = $this->getJsApiTicket();
    $url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
    $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
    $data = json_decode(file_get_contents("jSon_file/jsapi_ticket_".$this->User_ID.".json"));
    if ($data->expire_time < time()) {
      $accessToken = $this->getAccessToken();
      $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";
      $res = json_decode($this->httpGet($url));
      $ticket = $res->ticket;
      if ($ticket) {
        $data->expire_time = time() + 7000;
        $data->jsapi_ticket = $ticket;
        $fp = fopen("jSon_file/jsapi_ticket_".$this->User_ID.".json", "w");
        fwrite($fp, json_encode($data));
        fclose($fp);
        chmod("jSon_file/jsapi_ticket_".$this->User_ID.".json",0777);
      }
    } 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
    $data = json_decode(file_get_contents("jSon_file/access_token_".$this->User_ID.".json"));
    if ($data->expire_time < time()) {
      $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$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;
        $fp = fopen("jSon_file/access_token_".$this->User_ID.".json", "w");
        fwrite($fp, json_encode($data));
        fclose($fp);
        chmod("jSon_file/access_token_".$this->User_ID.".json",0777);
      }
    } 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_URL, $url);
 
    $res = curl_exec($curl);
    curl_close($curl);
 
    return $res;
  }
}

3.微信后台加密与算法

<?php
class JSSDK {
  private $appId;
  private $appSecret;
 
  public function __construct($appId, $appSecret) {
    $this->appId = $appId;
    $this->appSecret = $appSecret;
  }
 
  public function getSignPackage() {
    $jsapiTicket = $this->getJsApiTicket();
    $url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
    $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();
      $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$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()) {
      $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$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_URL, $url);
 
    $res = curl_exec($curl);
    curl_close($curl);
 
    return $res;
  }
}
