php获取小程序码的实现代码(B类接口)

效果图

生成小程序码的php代码

public function qrcode(){    $member_id = ssion('id');    if(empty($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'];    }el{      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 = "/d/file/titlepic/getwxacodeunlimit       $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);      $image = 'data:image/jpg;ba64,' . ba64_encode($result);             $other_result = $result;             $file = fopen($path,"w");//打开文件准备写入    fwrite($file,$other_result);//写入    fclo($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')->lect();    $path  = [];    foreach($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-chart: utf-8";    curl_topt($curl, curlopt_url, $url); // 要访问的地址    curl_topt($curl, curlopt_ssl_verifypeer, fal); // 对认证证书来源的检测    curl_topt($curl, curlopt_ssl_verifyhost, fal); // 从证书中检查ssl加密算法是否存在    curl_topt($curl, curlopt_httpheader, array('expect:')); //解决数据包大不能提交    curl_topt($c木炭还原氧化铜url, curlopt_followlocation, 1); // 使用自动跳转    curl_topt($curl, curlopt_autoreferer, 1); // 自动设置referer    curl_topt($curl, curlopt_post, 1); // 发送一个常规的post请求    curl_topt($curl, curlopt_postfields, $data); // post提交的数据包    curl_topt($curl, curlopt_timeout, 30); // 设置超时限制防止死循    curl_topt($curl, curlopt_header, 0); // 显示返回的header区域内容    curl_topt($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_clo($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; chart=utf-8","content-length: $a");  curl_topt($curl, curlopt_url, $url);  curl_topt($curl, curlopt_ssl_verifypeer, fal);  curl_topt($curl, curlopt_ssl_verifyhost, fal);  curl_topt($curl,curlopt_post,1);  curl_topt($curl,curlopt_postfields,$data);  curl_topt($curl, curlopt_header, 0);  curl_topt($curl, curlopt_returntransfer, 1);  $res = curl_exec($curl);  curl_clo($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.tdata({ 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.tdata({ 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 = "/d/file/titlepic/getwxacodeunlimit //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 = $this->filetoba64('/tmp/qr_code.png'); //将图片文件转化为ba64respon::result($img_string);}//本地文件转ba64private function filetoba64($file){$ba64_file = '';if(file_exists($file)){$mime_type= mime_content_type($file); //如果这里明确是图片的话我建议获取图片类型这句可以省略，直接知道了mine_type='image/png'，因为我这里我虽然存的图片，但是读到的mine_type值为text/plain$ba64_data = ba64_encode(file_get_contents($file));$ba64_file = 'data:'.$mime_type.';ba64,'.$ba64_data; //$ba64_file = 'data:image/png;ba64,'.$ba64_data; }return $ba64_file;}/*获取access_token,不需要code参数，不能用于获取用户信息的token*/public function getaccesstoken(){$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 = "/d/file/titlepic/token = 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($data));}} el {$access_token = $data->access_token;}return $access_token;}

感觉一个完整的php实现的代码目前我还没找到，这个自己用的还行。如有不恰当的地方，欢迎指出~ _
