微信公众号开发-分享

前台:

1.引入微信jdk->http://res.wx.qq.com/open/js/jweixin-1.6.0.js

2.请求签名等参数:

 $.ajax({
          type:'get',
            url: '/Weixin/Interviews/wxfx',
            data:{
                url:fromurl  //当前url链接
            },
          success: function (result) {  
              console.log(result)
              wx.checkJsApi({
              jsApiList: ['onMenuShareTimeline'], // 需要检测的JS接口列表,所有JS接口列表见附录2,
              success: function(res) {
              // 以键值对的形式返回,可用的api值true,不可用为false
              // 如:{"checkResult":{"chooseImage":true},"errMsg":"checkJsApi:ok"}
              }
            });
              if(result.status){
                   wx.config({
                  debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。
                  appId: result.info.appId, // 必填,公众号的唯一标识
                  timestamp: result.info.timestamp*1, // 必填,生成签名的时间戳
                  nonceStr: result.info.nonceStr, // 必填,生成签名的随机串
                  signature: result.info.signature,// 必填,签名
                  jsApiList: ['onMenuShareTimeline','onMenuShareAppMessage'] // 必填,需要使用的JS接口列表
                });
              }
            
                  
          }
        });
    1. private $appId;
    2. private $appSecret;
    3.  
    4. public function __construct($appId, $appSecret) {
    5. $this->appId = $appId;
    6. $this->appSecret = $appSecret;
    7. }
 

3.后台:

 
private $appId;
private $appSecret;
public function getConfig() {
$jsapiTicket = $this->getJsApiTicket(); $url = $_GET['url'] ? urldecode($_GET['url']) : 'https://' . $_SERVER['SERVER_NAME'] . $_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); $signature = strtolower($signature); $signPackage = array( "appId" => $this->AppID, "url" => $url, "nonceStr" => $nonceStr, "timestamp" => $timestamp, "signature" => $signature, "rawString" => $string, "jsapiTicket"=>$jsapiTicket ); 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; }

 

测试:

微信 JS 接口签名校验工具:https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=jsapisign

js接口安全域名:不加http://
