1.第一步下载二维码类文件
下载地址链接：https://pan.baidu.com/s/1ramNa2o 密码：8ok8
2.把类文件放到第三方类中： ThinkPHP\Library\Vendor\phpqrcode.php
3.首先微信公众平台账号有这个权限，没有的话去开通。
一切准备就绪开始上代码：
控制器里面方法代码为:
//推广二维码
public function extendewm()
{
$user_id=I('get.id');//获取当前登录用户id,后以做二维码参数(scene_id)
$usermobile=$_SESSION['usermobile'];//当前登录者用户手机号
//获取access_token
//请求url地址
$appId = 'wxc7245e01b2b4b965';
$appSecret = '5cb65e4111e750497e32fdf44c91a3b9';
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appId."&secret=".$appSecret;
//初始化curl
$ch = curl_init($url);
//3.设置参数
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);//跳过证书验证
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); // 从证书中检查SSL加密算法是否存在
//4.调用接口
$res = curl_exec($ch);
if(curl_errno($ch)){
var_dump(curl_error($ch));
}
$resArr = json_decode($res,true);
//5.关闭curl
curl_close($ch);
$access_token=$resArr['access_token'];
//创建二维码ticket,根据当前登陆者角色分别生成不同的ticket,进而生成临时和永久二维码
$usermobile=$_SESSION['usermobile'];//当前登录者用户手机号
$user=M('user');
$userdata=$user->where(array('tellphone'=>$usermobile))->find();
$user_id=$userdata['id'];
$role=$userdata['role'];
//$arrrole=explode(",",$role);
$url1="https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=".$access_token;
if($role==2)//商家属性
{

$curl = curl_init(); // 启动一个CURL会话
curl_setopt($curl, CURLOPT_URL, $url1); // 要访问的地址
