一、说明
1、本文主要是分享接口的实现和选择相册以及扫一扫的实现
2、参考慕课视频：/video/11353
3、参考手册：
https://mp./wiki?t=resource/res_main&id=mp1421141115
4、微信分享JS接口目前已失效，以前可以自定义分享的标题、描述、图片、链接地址在微信6.0.2版本中失效：

二、controller代码
<?phpnamespace Weixin\Controller;use Think\Controller;class IndexController extends Controller{/**$url 接口url string*$type 请求类型 string*$res 返回数据类型 string*%$arr post 请求参数 string*/public function http_curl($url,$type='get',$res='json',$arr=''){//1.初始化curl$ch = curl_init();//2.设置curl的参数curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);if($type == 'post'){curl_setopt($ch, CURLOPT_POST,1);curl_setopt($ch, CURLOPT_POSTFIELDS, $arr);}//3.采集$output = curl_exec($ch);//4.关闭curl_close($ch);if($res=='json'){if(curl_error($ch)){//请求失败，返回错误信息return curl_error($ch);}else{//请求成功，返回错误信息return json_decode($output,true);}}}/**返回access_token *session解决办法 存mysql memcache*/public function getWxAccessToken(){//将access_token 存在session/cookie中if($_SESSION['access_token'] && $_SESSION['expire_time'] > time()){//如果access_token在session中没有过期return $_SESSION['access_token'];}else{//如果access_token在session中不存在或者已经过期$appid = 'wxb20bebb764546087';$appsecret = '64e22d215895d52af21c8fcbf6da3241';$url = "https://api./cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$appsecret;$res = $this->http_curl($url,'get','json');$access_token = $res['access_token'];//将重新获取到的access_token存到session中$_SESSION['access_token'] = $access_token;$_SESSION['erpire_time'] = time() + 7000;return $access_token;}}//获取jsapi_ticket全局票据function getJsApiTicket(){//如果session中保存有效的jsapi_ticketif($_SESSION['jsapi_ticket_expire_time'] > time() && $_SESSION['jsapi_ticket']){$jsapi_ticket = $_SESSION['jsapi_ticket'];}else{$access_token = $this -> getWxAccessToken();$url = "https://api./cgi-bin/ticket/getticket?access_token=".$access_token."&type=jsapi";$res = $this -> http_curl($url);$jsapi_ticket = $res['ticket'];$_SESSION['jsapi_ticket'] = $jsapi_ticket;$_SESSION['jsapi_ticket_expire_time'] = time()+7000;}return $jsapi_ticket;}//获取随机码function getRandCode($num = 16){$array = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','v','z','1','2','3','4','5','6','7','8','9','0',);$tmpstr='';$max = count($array);for($i=1; $i<=$num; $i++){$key = rand(0,$max-1); //'A' -> $array[0]$tmpstr .= $array[$key];}return $tmpstr;}//function shareWx(){//1.获取jsapi_ticket票据$jsapi_ticket = $this->getJsApiTicket();echo $jsapi_ticket;echo '<br>';$timestamp = time();//echo '<br>';$noncestr = $this->getRandCode();//echo '<br>';//$url = 'http://www.cxf001.top/weixin.php/index/sharewx';//动态获取url$protocol = (!empty($_SERVER[HTTPS]) && $_SERVER[HTTPS] !== off || $_SERVER[SERVER_PORT] == 443) ?

三、share.html代码
