我在PHP中有以下类代码:
<?php
require_once CUSTOM_PATH . DIRECTORY_SEPARATOR . 'myneighborlists.php';
class Action_Get_route extends Frapi_Action implements Frapi_Action_Interface
{
/**
* Required parameters
*
* @var An array of required parameters.
*/
protected $requiredParams = array();
/**
* The data container to use in toArray()
*
* @var A container of data to fill and return in toArray()
*/
private $data = array();
/**
* To Array
*
* This method returns the value found in the database
* into an associative array.
*
* @return array
*/
public function toArray()
{
//$this->data['origin'] = $this->getParam('origin', self::TYPE_OUTPUT);
//$this->data['destination'] = $this->getParam('destination', self::TYPE_OUTPUT);
return $this->data;
}
/**
* Default Call Method
*
* This method is called when no specific request handler has been found
*
* @return array
*/
public function executeAction()
{
$valid = $this->hasRequiredParameters($this->requiredParams);
if ($valid instanceof Frapi_Error) {
return $valid;
}
return $this->toArray();
}
/**
* Get Request Handler
*
* This method is called when a request is a GET
*
* @return array
*/
public function executeGet()
{
$valid = $this->hasRequiredParameters($this->requiredParams);
if ($valid instanceof Frapi_Error) {
return $valid;
}
return $this->toArray();
}
/**
* Post Request Handler
*
* This method is called when a request is a POST
*
* @return array
*/
public function executePost()
{
$valid = $this->hasRequiredParameters($this->requiredParams);
if ($valid instanceof Frapi_Error) {
return $valid;
}
return $this->toArray();
}
/**
* Put Request Handler
*
* This method is called when a request is a PUT
*
* @return array
*/
public function executePut()
{
$valid = $this->hasRequiredParameters($this->requiredParams);
if ($valid instanceof Frapi_Error) {
return $valid;
}
return $this->toArray();
}
/**
* Delete Request Handler
*
* This method is called when a request is a DELETE
*
* @return array
*/
public function executeDelete()
{
$valid = $this->hasRequiredParameters($this->requiredParams);
if ($valid instanceof Frapi_Error) {
return $valid;
}
return $this->toArray();
}
/**
* Head Request Handler
*
* This method is called when a request is a HEAD
*
* @return array
*/
public function executeHead()
{
$valid = $this->hasRequiredParameters($this->requiredParams);
if ($valid instanceof Frapi_Error) {
return $valid;
}
return $this->toArray();
}
}
这基本上是REST API的类模板,当我调用get方法时,我得到的响应总是有一个额外的新行。当我删除require_once时,额外的新行就消失了。如何避免这条额外的新线? This is我的新意思是什么。

在所需文件中关闭?>
标记后,查看是否有额外的行或空格。所需文件中可能存在回显空格/行,或文件末尾有额外空格的内容。
