PHP 调用微信JS-SDK 开发详解 [网摘]

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}
 
下面是一个jssdk的类文件
  文件:jssdk.php
 1 <?php
 2 class JSSDK {
 3   private $appId;
 4   private $appSecret;
 5   public function __construct($appId, $appSecret) {
 6     $this->appId = $appId;
 7     $this->appSecret = $appSecret;
 8   }
 9   public function getSignPackage() {
10     $jsapiTicket = $this->getJsApiTicket();
11     $url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
12     $timestamp = time();
13     $nonceStr = $this->createNonceStr();
14     // 这里参数的顺序要按照 key 值 ASCII 码升序排序
15     $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";
16     $signature = sha1($string);
17     $signPackage = array(
18       "appId"     => $this->appId,
19       "nonceStr"  => $nonceStr,
20       "timestamp" => $timestamp,
21       "url"       => $url,
22       "signature" => $signature,
23       "rawString" => $string
24     );
25     return $signPackage; 
26   }
27   private function createNonceStr($length = 16) {
28     $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
29     $str = "";
30     for ($i = 0; $i < $length; $i++) {
31       $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
32     }
33     return $str;
34   }
35   private function getJsApiTicket() {
36     // 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
37     $data = json_decode(file_get_contents("jsapi_ticket.json"));
38     if ($data->expire_time < time()) {
39       $accessToken = $this->getAccessToken();
40       $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";
41       $res = json_decode($this->httpGet($url));
42       $ticket = $res->ticket;
43       if ($ticket) {
44         $data->expire_time = time() + 7000;
45         $data->jsapi_ticket = $ticket;
46         $fp = fopen("jsapi_ticket.json", "w");
47         fwrite($fp, json_encode($data));
48         fclose($fp);
49       }
50     } else {
51       $ticket = $data->jsapi_ticket;
52     }
53     return $ticket;
54   }
55   private function getAccessToken() {
56     // 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
57     $data = json_decode(file_get_contents("access_token.json"));
58     if ($data->expire_time < time()) {
59       $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret";
60       $res = json_decode($this->httpGet($url));
61       $access_token = $res->access_token;
62       if ($access_token) {
63         $data->expire_time = time() + 7000;
64         $data->access_token = $access_token;
65         $fp = fopen("access_token.json", "w");
66         fwrite($fp, json_encode($data));
67         fclose($fp);
68       }
69     } else {
70       $access_token = $data->access_token;
71     }
72     return $access_token;
73   }
74   private function httpGet($url) {
75     $curl = curl_init();
76     curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
77     curl_setopt($curl, CURLOPT_TIMEOUT, 500);
78     curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
79     curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
80     curl_setopt($curl, CURLOPT_URL, $url);
81     $res = curl_exec($curl);
82     curl_close($curl);
83     return $res;
84   }
85 }

二：编辑显示页面对应的后台PHP文件，添加如下代码

1       include('jssdk.php');
2       $jssdk = new JSSDK("APPID", "APPSECRET");
3       $signPackage = $jssdk->GetSignPackage(); 
4        
5       $this->signPackage = $signPackage;

请将APPID和APPSECRET换成您自己微信账号的信息

三：编辑显示页面模板html文件，添加如下代码

 1 <script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
 2 <script>
 3 wx.config({
 4     appId: '{suetech:$signPackage.appId}',
 5     timestamp: {suetech:$signPackage.timestamp},
 6     nonceStr: '{suetech:$signPackage.nonceStr}',
 7     signature: '{suetech:$signPackage.signature}',
 8    jsApiList: [
 9         'checkJsApi',
10         'onMenuShareTimeline',
11         'onMenuShareAppMessage',
12         'onMenuShareQQ',
13         'onMenuShareWeibo'
14       ]
15   });
16   /*
17  * 注意：
18  * 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”。
19  * 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。
20  * 3. 完整 JS-SDK 文档地址：http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
21  *
22  * 如有问题请通过以下渠道反馈：
23  * 邮箱地址：weixin-open@qq.com
24  * 邮件主题：【微信JS-SDK反馈】具体问题
25  * 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。
26  */
27 wx.ready(function () {
28   // 1 判断当前版本是否支持指定 JS 接口，支持批量判断
29     wx.checkJsApi({
30       jsApiList: [
31         'getNetworkType',
32         'previewImage',
33          'onMenuShareTimeline',
34         'onMenuShareAppMessage',
35         'onMenuShareQQ',
36         'onMenuShareWeibo'
37       ],
38       success: function (res) {
39         alert(JSON.stringify(res));
40       }
41     });
42   var shareData = {
43     title: '标题',
44       desc: '描述',
45       link: '链接',
46       imgUrl: '图片',
47       trigger: function (res) {
48         alert('用户点击发送给朋友');
49       },
50       success: function (res) {
51         alert('已分享');
52       },
53       cancel: function (res) {
54         alert('已取消');
55       },
56       fail: function (res) {
57         alert(JSON.stringify(res));
58       }
59   };
60   wx.onMenuShareAppMessage(shareData);
61   wx.onMenuShareTimeline(shareData);
62   wx.onMenuShareQQ(shareData);
63   wx.onMenuShareWeibo(shareData);
64 });
65 wx.error(function (res) {
66   alert(res.errMsg);
67 }); 
68 </script>

 

到此已经能够正常进行微信自定义分享了

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
