如今微信已经成为日常生活中必不可缺少的一部分，微信用户到目前已经达到3个亿了吧！每个用户都或多或少的关注过一些公众账号，作为一名合格的前端，你怎么可以。闲话不多说了下面开始教大家微信开放平台。

先注册新浪云

接下来先上传你的代码包，必须打包为zip格式。

index.php 中的代码修改，代码中需要获取微信的AppId，在后文教大家获取，先埋个坑。

<?php
require_once "jssdk.php";
$jssdk = new JSSDK("wx083768d702e828d4", "0b7b2b17725ee65d129976fc2d63014b");  //从微信配置复制过来的
$signPackage = $jssdk->GetSignPackage();
?>

        <script type="text/javascript" src="lib/require.js" data-main = "main" ></script>
    </head>
    <body>

    </body>
    <script type="text/javascript">
        var evt = "onorientationchange" in window ? "orientationchange" : "resize";
        var doc = document.documentElement;
        window.addEventListener(evt, _resize, false);
        window.addEventListener("DOMContentLoaded", _resize);
        function _resize() {
            doc.style.fontSize = 20 * (doc.clientWidth / 320) + "px";
        } 
    </script>
    <!-- 微信的一些api接口 -->
    <script>
            wx.config({
            debug: false,
            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
               "scanQRCode","getLocation"
            ]
          });
    </script>
</html>

还需要一个jssdk.php 文件(这个文件是通用的)，代码为

<?php
error_reporting(E_ERROR);
class JSSDK {
  private $appId;
  private $appSecret;

  public function __construct($appId, $appSecret) {
    $this->appId = $appId;
    $this->appSecret = $appSecret;
  }

  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]";

    $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=$nonceStr×tamp=$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
    $data = json_decode($this->get_php_file("jsapi_ticket.php"));
    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;
        $this->set_php_file("jsapi_ticket.php", json_encode($data));
      }
    } 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
    $data = json_decode($this->get_php_file("access_token.php"));
    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;
        $this->set_php_file("access_token.php", json_encode($data));
      }
    } else {
      $access_token = $data->access_token;
    }
    return $access_token;
  }

  private function httpGet($url) {
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_TIMEOUT, 500);
    // 为保证第三方服务器与微信服务器之间数据传输的安全性，所有微信接口采用https方式调用，必须使用下面2行代码打开ssl安全校验。
    // 如果在部署过程中代码在此处验证失败，请到 http://curl.haxx.se/ca/cacert.pem 下载新的证书判别文件。
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);
    curl_setopt($curl, CURLOPT_URL, $url);

    $res = curl_exec($curl);
    curl_close($curl);

    return $res;
  }

  private function get_php_file($filename) {
    return trim(substr(file_get_contents($filename), 15));
  }
  private function set_php_file($filename, $content) {
    $fp = fopen($filename, "w");
    fwrite($fp, "<?php exit();?>" . $content);
    fclose($fp);
  }
}
// $appId = $_REQUEST["appId"];
// $appSecret = $_REQUEST["appSecret"];
// $jssdk = new JSSDK($appId, $appSecret);
// $signPackage = $jssdk->GetSignPackage();
// echo json_encode($signPackage);
