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; }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~ _
