Question

我正在尝试在Codeigniter中创建RESTful API服务器。到目前为止，我按照我从https://github.com/philsturgeon/codeigniter-restserver获得的指示。到目前为止一切顺利，我创建了一个简单的控制器来测试，所以我构建了一个hello.php：

<?php 

include(APPPATH.'libraries/REST_Controller.php');

class Hello extends REST_Controller {
  function world_get() {
    $data->name = "TESTNAME";
    $this->response($data); 
  }
}

?>

当我尝试通过输入http://localhost/peojects/ci/index.php/hello/world来运行它时，我收到错误：

<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message:  Creating default object from empty value</p>
<p>Filename: controllers/hello.php</p>
<p>Line Number: 7</p>

</div>{"name":"TESTNAME"}

这里有什么问题？

先前未设置/定义

$data。您需要执行以下操作：$data = new StdObject;然后为其指定属性：$data -> name = "TESTNAME";

class Hello extends REST_Controller {
  function world_get() {
    $data = new StdObject;
    $data->name = "TESTNAME";
    $this->response($data); 
  }
}

或者根据示例，您可以改为使用数组：

class Hello extends REST_Controller {
  function world_get() {
    $data = array();
    $data['name'] = "TESTNAME";
    $this->response($data); 
  }
}
