CakePHP错误：调用非对象上的成员函数parseAccept（） [英] CakePHP Error: Call to a member function parseAccept() on a non-object

问题描述

我刚从 CakePHP 1.3 升级至 cakePHP 2.4.5 。

我得到以下错误：

 致命错误
错误：对非对象的函数parseAccept（）
文件：/myapp/lib/Cake/Controller/Component/RequestHandlerComponent.php 
行：157 
  

我不是在我的控制器中的任何地方调用函数 parseAccept（），所以不明白为什么我收到此错误。

解决方案

从蛋糕手册

控制器的构造函数现在有两个参数。 CakeRequest和
CakeResponse对象。这些对象用于填充多个
不推荐的属性，并将
中的$ request和$ response设置为控制器。

---

修正：

更改您的构造函数签名..

从：

  function __construct（）
 {
 parent :: __ construct（）; 
} 
  

收件人：

  //通过请求和响应对象
 //并声明方法的可见性
 public function __construct（$ request = null，$ response = null）
 {
 parent :: __ construct（$ request，$ response）; 
} 
  

这应该可以解决您的错误：



官方 Cake 2.x docs 可以在这里找到：

如果您刚刚从 1.x 升级到 2.x ，我强烈建议您阅读 cakePHP 提供的详细迁移指南。

I have just upgraded from CakePHP 1.3 to cakePHP 2.4.5.

I am getting the following error:

Fatal Error
Error: Call to a member function parseAccept() on a non-object  
File: /myapp/lib/Cake/Controller/Component/RequestHandlerComponent.php  
Line: 157

I'm not calling the function parseAccept() anywhere within my controller, and so don't understand why I am getting this error.

解决方案

From the Cake Manual

Controller’s constructor now takes two parameters. A CakeRequest, and CakeResponse objects. These objects are used to populate several deprecated properties and will be set to $request and $response inside the controller.

---

The Fix:

Change your constructor signature..

From:

function __construct()
{
    parent::__construct();
}

To:

// Pass through the request and response objects 
// AND declare the visibility of the method
public function __construct($request = null, $response = null)
{
    parent::__construct($request, $response);
}

This should resolve your Error: Call to a member function parseAccept() on a non-object.

The official Cake 2.x docs for this issue can be found here:

If you have just upgraded from 1.x to 2.x, I would highly recommend you read through the detailed migration guides provided by cakePHP.
