xxggmmxx

• 代码：
  /**
  * @desc：获取前端提交的数据，支持数据过滤
  * @author [Lee]
  */
  class getrequest{
  /*
  @desc：内部函数：过滤危险数据
  */
  private function safetydata($data){
  foreach($data as $k=>$v){
  if(is_array($v)){
  $data[$k] = $this->safetydata($v);
  }else{
  $tmp = trim($v);
  $tmp = addslashes($tmp);
  $data[$k] = $tmp;
  }
  }
  return $data;
  }
  /*
  @desc：判断前端传入方式，转换成能用数据
  */
  public function getrequestdata(){
  $data;
  $ret;
  $contenttype = strtolower($_SERVER['CONTENT_TYPE']);
  $method = strtolower($_SERVER['REQUEST_METHOD']);
  if($contenttype == 'application/json'){
  $data = file_get_contents('php://input');
  $data = json_decode($data,true);
  }elseif(in_array($contenttype,array('application/x-www-form-urlencoded','multipart/form-data')) || $method == 'post'){
  $data = $_POST;
  }elseif(in_array($contenttype,array('application/x-www-form-urlencoded','multipart/form-data')) || $method == 'get'){
  $data = $_GET;
  }else{
  parse_str(file_get_contents('php://input'),$data);
  }
  $ret = $this->safetydata($data);
  return $ret;
  }
  }
  
• 用法：
  $getrequest = new getrequest();
  $data = $getrequest->getrequestdata();
  var_dump($data);
