thinkphp调用微信jssdk开发

一:准备文件,并将文件置于网站根目录下

access_token.json
{"access_token":"","expire_time":0}

  

 jsapi_ticket.json
{"jsapi_ticket":"","expire_time":0}

  

 
jssdk.php
<?php
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=$nonceStr&timestamp=$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
    $data = json_decode($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);
  }
}

  

 二:编辑显示页面对应的后台PHP文件,添加如下代码 jssdk.php 我放在verdor/weixin/ 下面
Vendor(‘weixin.jssdk‘);
   
$jssdk = new JSSDK("APPID", "APPSECRET");       

$signPackage = $jssdk->GetSignPackage();              

$this->signPackage = $signPackage;

  

 三:在需要页面上或公共js里(所有页面)
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
  wx.config({
    appId: ‘{suetech:$signPackage.appId}‘,
    timestamp: {suetech:$signPackage.timestamp},
    nonceStr: ‘{suetech:$signPackage.nonceStr}‘,
    signature: ‘{suetech:$signPackage.signature}‘,
    jsApiList: [
      ‘checkJsApi‘,
      ‘onMenuShareTimeline‘,
      ‘onMenuShareAppMessage‘,
      ‘onMenuShareQQ‘,
      ‘onMenuShareWeibo‘
    ]
  });
/*
* 注意:
* 1. 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”。
* 2. 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。
* 3. 完整 JS-SDK 文档地址:http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
*
* 如有问题请通过以下渠道反馈:
* 邮箱地址:weixin-open@qq.com
* 邮件主题:【微信JS-SDK反馈】具体问题
* 邮件内容说明:用简明的语言描述问题所在,并交代清楚遇到该问题的场景,可附上截屏图片,微信团队会尽快处理你的反馈。
*/
wx.ready(function () {
  // 1 判断当前版本是否支持指定 JS 接口,支持批量判断
  wx.checkJsApi({
    jsApiList: [
      ‘getNetworkType‘,
      ‘previewImage‘,
      ‘onMenuShareTimeline‘,
      ‘onMenuShareAppMessage‘,
      ‘onMenuShareQQ‘,
      ‘onMenuShareWeibo‘
    ],
    success: function (res) {
      alert(JSON.stringify(res));
    }
  });
  var shareData = {
    title: ‘标题‘,
    desc: ‘描述‘,
    link: ‘链接‘,
    imgUrl: ‘图片‘,
    trigger: function (res) {
      alert(‘用户点击发送给朋友‘);
    },
    success: function (res) {
      alert(‘已分享‘);
    },
    cancel: function (res) {
      alert(‘已取消‘);
    },
    fail: function (res) {
      alert(JSON.stringify(res));
    }
  };
  wx.onMenuShareAppMessage(shareData);
  wx.onMenuShareTimeline(shareData);
  wx.onMenuShareQQ(shareData);
  wx.onMenuShareWeibo(shareData);
});
wx.error(function (res) {
  alert(res.errMsg);
}); 
</script>  

 

如果报错curl_setopt(): CURLOPT_SSL_VERIFYHOST with value 1 is deprecated and will be removed as of libcurl 7.28.1. It is recommended to use value 2 instead

修改

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);

 

需要注意的地方是在微信公众账号中配置您的域名,设置方法:

登陆微信公众账号->公众号设置->功能设置->JS接口安全域名->设置
