Thinkphp 微信公众平台开发-模板消息

使用thinkphp开发微信公众平台，今天在做模板消息功能，把自己封装好的类分享给大家
开发模板消息，即如何用程序发送模板消息功能，分为以下三个部分：
1.申请模板消息权限 【这里不讲解】
2.开发模板消息SDK
3.构造模板消息体并发送

开发模板消息SDK

模板消息也是使用access token作为授权来发送。

在thinkphp  Common\Lib里新建一个WeiXin.class.php类，代码如下：

1. <?php 
2.  
3. namespace Common\Lib; 
4.  
5. class WeiXin{ 
6.      public $appid; 
7.      public $appsecret; 
8.      public  $access_token; 
9.       
10.       public function __construct(){ 
11.        $config = C("THINK_SDK_WXOAUTH"); 
12.          
13.          $this->appid = $config['APP_KEY']; 
14.          $this->appsecret = $config['APP_SECRET']; 
15.         //判断access_token是否存在，不存在重新获取 
16.          if(session('access_token_bd')){ 
17.               $this->access_token =  session('access_token_bd'); 
18.          }else{ 
19.               $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->appsecret; 
20.               $res = json_decode($this->http_request($url),true); 
21.               $this->access_token = $res['access_token']; 
22.               session(array('name'=>'access_token_bd','value'=>$this->access_token,'expire'=>7200));//保存access_token  
23.          } 
24.      
25.           
26.           
27.           
28.       } 
29.        
30.       //发送模板消息 
31.       public function send_template_message($data){ 
32.                 
33.          
34.               $url="https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=".$this->access_token; 
35.               $res=$this->http_request($url,$data); 
36.               return $res; 
37.               return json_decode($res,true); 
38.       } 
39.  
40.      
41.     public function template($uid,$template_id,$data,$url,$topcolor){ 
42.          
43.        $member=M('member')->where(array('id'=>$uid))->find(); 
44.        $openid=$member['openid']; //根据用户id获取数据库保存的openid
45.         switch($template_id){ 
46.            case 1: 
47.            $tpl="PTaLGaNTX96ygKhzdaSV3b5sMeR639vtnJcjK830pfI";//客户预约通知 
48.            break; 
49.            case 2: 
50.            $tpl="dy2JfGwROKwiLps0jUUXzq9v5hOkBWduFbA3ph5CTrQ";//预约成功提醒 
51.            break; 
52.            case 3: 
53.            $tpl="esK5kFS8BHx6EiDJ2mkszKsijTU5TJKDyEEuqEessHY";//任务通知 
54.            break; 
55.            case 4: 
56.            $tpl="mtklmdaJ2TCWOS8Taoxjm15bVFRa0Rj5GtdVqvPlLq0";//订单完成通知 
57.            break; 
58.            case 5: 
59.            $tpl="pF0szsKuAh2u7ziqH3Im0GscRwrXaUNwXGrUNZKYHy8";//任务完成通知 
60.            break; 
61.            case 2: 
62.            $tpl="pXFC-Lc4TgiAl-nQWMMbD7eLoi25SIWgSU3IXrcKcmw";//订单待支付提醒 
63.            break; 
64.            default: 
65.             $tpl = ''; 
66.             break; 
67.             
68.         } 
69.         if(!$tpl){ 
70.           return ''; 
71.         } 
72.         $template=array('touser'     =>$openid, 
73.                         'template_id'=>$tpl, 
74.                         'url'        =>$url, 
75.                         'topcolor'   =>$topcolor, 
76.                         'data'       =>$data 
77.                  ); 
78.      
79.      
80.     return $template; 
81.      
82.     } 
83.      
84.      
85.      
86.      
87.     protected function http_request($url,$data=null){ 
88.       $curl = curl_init(); 
89.       curl_setopt($curl,CURLOPT_URL,$url); 
90.       curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,FALSE); 
91.       curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,FALSE); 
92.       if(!emptyempty($data)){ 
93.          curl_setopt($curl,CURLOPT_POST,1); 
94.          curl_setopt($curl,CURLOPT_POSTFIELDS,$data); 
95.       } 
96.       curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); 
97.       $output = curl_exec($curl); 
98.       curl_close($curl); 
99.       return $output; 
100.    
101.   } 
102.  
103.  
104.    
105. } 

构造模板消息体并发送

 

1. $uid=get_cookie('uid');//获取用户id 
2.                  $data= array('first'  => array('value'=>urlencode("测试数据"),'color'=>''), 
3.                               'keyword1' => array('value'=>urlencode("王三"),'color'=>''), 
4.                               'keyword2' => array('value'=>"15250735030",'color'=>''), 
5.                               'keyword3' => array('value'=>"2016-8-26",'color'=>''), 
6.                               'keyword4' => array('value'=>urlencode("预约拉货"),'color'=>''), 
7.                               'remark'   => array('value'=>urlencode("感谢选择我们"),'color'=>''),                   
8.                         ); 
9.                  $wxtlp = new \Common\Lib\WeiXin(); 
10.                  $template = $wxtlp->template($uid,1,$data); 
11.                  $res=$wxtlp->send_template_message(urldecode(json_encode($template))); 
12.                  $data=json_decode($res,true); 
13.                  print_r($data);exit; 

在调用模板消息接口后，会返回JSON数据包。正常时的返回JSON数据包示例：

    {
           "errcode":0,
           "errmsg":"ok",
           "template_id":"Doclyl5uP7Aciu-qZ7mJNPtWkbkYnWBWVja26EGbNyk"
       }
