代码分三部分进行，第一部分是C层（Controller），第二部分是M层(Model)，第三部分是V层(View)
1.控制器层WeixinController
$data = array(
\'pic\'=>\'\',//图片地址 \'title\'=>\'\',//标题
\'description\'=>\'\'//描述
);
$weixinmodel = new WeixinshareModel();
$weixindata = array();
$weixindata[\'appId\'] = \'xxxxxxxxxxxxxxxxxxxx\';//appid
$weixindata[\'nonceStr\'] = $weixinmodel->createNonceStr();
$weixindata[\'timestamp\'] = time();
$protocol = (!empty($_SERVER[\'HTTPS\']) && $_SERVER[\'HTTPS\'] !== \'off\' || $_SERVER[\'SERVER_PORT\'] == 443) ? "https://" : "http://";
$url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$weixindata[\'pic\'] = $data[\'pic\'];
$weixindata[\'link\'] = $url;
$weixindata[\'title\'] = $data[\'title\'];
$weixindata[\'description\'] = mb_substr($data[\'description\'], 0, 30, \'UTF-8\');
$weixindata[\'signature\'] = $weixinmodel->signature($weixindata[\'nonceStr\'],$weixindata[\'timestamp\'],$url);
$this->assign("weixindata", $weixindata);
2.模型层WeixinModel
<?php
class WeixinshareModel extends baseModel
{
const APPID = \'xxxxxxxxxxxxxxx\';
const APPSECRET = \'xxxxxxxxxxxxxxxxxxxxxxxx\';
function __construct()
{
parent::__construct();
}
//获取access_token
public function accessToken()
{
$access_token = $this->redis->get("weixin_access_token");//存入redis，这里要结合自己的项目，对redis或者memcahe进行设置
if(!$access_token){
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".self::APPID."&secret=".self::APPSECRET;
$data = json_decode($this->httpGet($url),true);
if(isset($data[\'access_token\']) && $data[\'access_token\'] != \'\'){
$access_token = $this->redis->set("weixin_access_token",$data[\'access_token\'],7200);
}else{
return false;
}
}
return $access_token;
}
//用第一步拿到的access_token 采用http GET方式请求获得jsapi_ticket
public function jsapiTicket()
{
$jsapi_ticket = $this->redis->get("weixin_jsapi_ticket");
if(!$jsapi_ticket){
$access_token = $this->accessToken();
if($access_token){
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=".$access_token."&type=jsapi";
$data = json_decode($this->httpGet($url),true);
if(isset($data[\'errcode\']) && $data[\'errcode\']== 0){//请求成功
$jsapi_ticket = $this->redis->set("weixin_jsapi_ticket",$data[\'ticket\'],7200);
}else{
return false;
}
}else{
return false;
}
}
return $jsapi_ticket;
}
//获取signature
public function signature($nonceStr,$timestamp,$url)
{
$jsapi_ticket = $this->jsapiTicket();
$signature = \'\';
if($jsapi_ticket) {
$string = "jsapi_ticket=$jsapi_ticket&noncestr=$nonceStr×tamp=$timestamp&url=$url";
$signature = sha1($string);//对string1进行sha1签名，得到signature
}else{
return false;
}
return $signature;
}
//生成随机字符串
public function createNonceStr($length = 16) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$str = "";
for ($i = 0; $i < $length; $i++) {
$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
}
return $str;
}
//远程请求，可以调用自己项目的远程请求
public function httpGet($url)
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_URL, $url);
$res = curl_exec($curl);
curl_close($curl);
return $res;
}
}

// config信息验证后会执行ready方法，所有接口调用都必须在config接口获得结果之后，config是一个客户端的异步操作，所以如果需要在页面加载时就调用相关接口，则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口，则可以直接调用，不需要放在ready函数中。
