$litpic = $member['share_qrcode'];
}else{
header('content-type:image/jpg');//加载速度快
// 生成小程序码
$wechatObj = new \Wechat();//这是个类 这里有小程序appid和密码
$url = "https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=".$wechatObj->getAccessToken();
$page = 'pages/index/index';
$scene = 'share_id='.$member_id;
$path = './upload/qrcode/'.$member_id.'.jpg';
$postData = array();

$data = json_encode($postData);
$result = $this->api_notice_increment($url,$data);

$other_result = $result;
$file = fopen($path,"w");//打开文件准备写入
fwrite($file,$other_result);//写入
fclose($file);//关闭
//return $result;
$litpic = $path;
$litpic = ltrim($litpic,'.');
//写入数据库
$member->save(['share_qrcode'=>$litpic,'is_share'=>1]);
}
//推广人数

}小程序端获取二维码中带的参数
/**

onLoad: function(option) {
console.log(option)
if(option.id){
this.setData({ id: option.id });
this.data.business_id = option.id;
this.loadData(option.id);
}
//接受二维码扫码并获取二维码中的参数
if (option.scene){

PHP获取小程序码并返回前端显示图片
小程序的二维码分为小程序码和二维码；
生成小程序二维码文档中说后端来生成。
参考 小程序开发文档资料：https://developers.weixin.qq.com/miniprogram/dev/api/getWXACodeUnlimit.html
文档的参数介绍还是蛮详细的，但是没有具体的demo,对于请求的接口的返回值是进制流（也就是在浏览器显示一堆乱码）也是很令人懊恼，这里贴一下我的代码：
//获取小程序码，这里调用的是小程序码的A接口类型
public function getQRCodeAction()
{
$data['scene'] = $this->_req->getQuery('shareId',11); //scence、page的使用要参考文档(比如：scene的值不能超过32个字符等）
$data['width'] = $this->_req->getQuery('width',220);
$data['auto_color'] = $this->_req->getQuery('auto_color');
$data['line_color'] = $this->_req->getQuery('line_color');
$data['is_hyaline'] = $this->_req->getQuery('is_hyaline',true);
$data['page'] = $this->_req->getQuery('page',""); //由这行以上代码是二维码的样式等由前端传值的形式，也可以直接在后端设置
$wxModel = new WxAuthModel();
$token = $wxModel->getAccessToken();
$res_url = "https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=$token"; //请求微信提供的接口
header('content-type:image/png');
$data = json_encode($data);
$Qr_code = $wxModel->http_request($res_url,$data); //到这里就已经返回微信提供的返回数据了，这个时候的数据是二进制流，要处理下再返回给前端
file_put_contents('/tmp/qr_code.png', $Qr_code); //将获得的数据读到一个临时图片里
$img_string = $this->fileToBase64('/tmp/qr_code.png'); //将图片文件转化为base64
response::result($img_string);
}
//本地文件转base64
private function fileToBase64($file){
$base64_file = '';
if(file_exists($file)){
$mime_type= mime_content_type($file); //如果这里明确是图片的话我建议获取图片类型这句可以省略，直接知道了mine_type='image/png'，因为我这里我虽然存的图片，但是读到的mine_type值为text/plain
$base64_data = base64_encode(file_get_contents($file));
$base64_file = 'data:'.$mime_type.';base64,'.$base64_data; //$base64_file = 'data:image/png;base64,'.$base64_data;
}
return $base64_file;
}
/*获取access_token,不需要code参数，不能用于获取用户信息的token*/
public function getAccessToken()
{
$token_file = '/dev/shm/heka2_token.json'; //由于获取token的次数存在限制，所以将一段时间内的token缓存到一个文件（注意缓存路径服务器支持可写可读），过期后再重新获取
$data = json_decode(file_get_contents($token_file));
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->http_request($url));
$access_token = $res->access_token;
if ($access_token) {
$data->expire_time = time() + 7000;
$data->access_token = $access_token;
file_put_contents($token_file, json_encode($data));
}
} else {
$access_token = $data->access_token;
}
return $access_token;
