这篇文章将为大家详细讲解有关php如何获取小程序码,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
效果图
生成小程序码的php代码
public function qrcode(){ $member_id = session('id'); if(empty($member_id)) $this->error('请先登录'); //推广二维码 $member = model('Member')->where('id',$member_id)->find(); if($member['is_share'] && $member['share_qrcode']){ $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(); $postData['page'] = $page; $postData['scene'] = $scene; $data = json_encode($postData); $result = $this->api_notice_increment($url,$data); $image = 'data:image/jpg;base64,' . base64_encode($result); $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 $path_member = model('Member')->where('path',$member_id)->field('id,name,litpic,add_time')->select(); $path = []; foreach($path_member as $v){ $v['add_time'] = date('Y-m-d H:i:s',$v['add_time']); $path[] = $v; } $data = [ 'litpic' => $litpic, 'path' => $path, ]; return json($data); } public function api_notice_increment($url,$data){ //return $data; $curl = curl_init(); // 启动一个CURL会话 //$header = "Accept-Charset: utf-8"; curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 对认证证书来源的检测 curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); // 从证书中检查SSL加密算法是否存在 curl_setopt($curl, CURLOPT_HTTPHEADER, array('Expect:')); //解决数据包大不能提交 curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转 curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求 curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包 curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循 curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回 $tmpInfo = curl_exec($curl); // 执行操作 if (curl_errno($curl)) { echo 'Errno'.curl_error($curl); } curl_close($curl); // 关键CURL会话 return $tmpInfo; // 返回数据 } function api_notice_increment($url,$data) { $curl = curl_init(); $a = strlen($data); $header = array("Content-Type: application/json; charset=utf-8","Content-Length: $a"); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl,CURLOPT_POST,1); curl_setopt($curl,CURLOPT_POSTFIELDS,$data); curl_setopt($curl, CURLOPT_HEADER, 0); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $res = curl_exec($curl); curl_close($curl); return $res; }
小程序端获取二维码中带的参数
/** * 生命周期函数--监听页面加载 */ 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){ const ids = decodeURIComponent(option.scene).split('=')[1]; console.log("ids", ids); this.setData({ id: ids }); this.data.business_id = ids; this.loadData(ids); } },

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; }
