使用Codeigniter获取PUT请求 [英] get a PUT request with Codeigniter

问题描述

我现在遇到CodeIgniter的问题：我使用 REST控制器库（这真的很棒）创建一个API，但我不能得到PUT请求...

这是我的代码：

  function user_put（）{
 $ user_id = $ this-> get（id）; 
 echo $ user_id; 
 $ username = $ this-> put（username）; 
 echo $ username; 
} 
  

我使用curl提出请求：

  curl -i -X PUT -dusername = testhttp：// [...] / user / id / 1 
  

user_id已满，但username变量为空。然而它适用于动词POST和GET。

解决方案

根据： http://net.tutsplus.com / tutorials / php / working-with-restful-services-in-codeigniter-2 / ，我们应该咨询https://github.com/philsturgeon/codeigniter-restserver/blob/master/application/libraries/REST_Controller.php#L544 查看此方法：

  / ** 
 *检测方法
 * 
 *检测哪个方法（POST，PUT，GET ，DELETE）正在使用
 * 
 * @return string 
 * / 
 protected function _detect_method（）{
 $ method = strtolower（$ this-> input - > server（'REQUEST_METHOD'））; 
 
 if（$ this-> config-> item（'enable_emulate_request'））{
 if（$ this-> input-> post 
 $ method = strtolower（$ this-> input-> post（'_ method'））; 
} else if（$ this-> input-> server（'HTTP_X_HTTP_METHOD_OVERRIDE'））{
 $ method = strtolower（$ this-> input-> server（'HTTP_X_HTTP_METHOD_OVERRIDE'）） ; 
} 
} 
 
 if（in_array（$ method，array（'get'，'delete'，'post'，'put'）））{
 return $ method; 
} 
 
 return'get'; 
} 
  

查看是否已定义HTTP标头 HTTP_X_HTTP_METHOD_OVERRIDE ，它使用它来支持我们在网络上实现的实际动词。要在请求中使用这个，你可以指定标头 X-HTTP-Method-Override：method （因此 X-HTTP-Method-Override：put ）生成自定义方法覆盖。有时框架期望 X-HTTP-Method 而不是 X-HTTP-Method-Override

如果您通过jQuery执行此类请求，那么您可以将此块集成到您的ajax请求中：

  beforeSend：function（XMLHttpRequest）{
 //指定执行删除操作的HTTP方法DELETE。 
 XMLHttpRequest.setRequestHeader（X-HTTP-Method-Override，DELETE）; 
} 
  

I have a problem right now with CodeIgniter : I use the REST Controller library (which is really awesome) to create an API but I can not get PUT requests...

This is my code :

function user_put() {
    $user_id = $this->get("id");
    echo $user_id;
    $username = $this->put("username");
    echo $username;
}

I use curl to make the request :

curl -i -X PUT -d "username=test" http://[...]/user/id/1

The user_id is full but the username variable is empty. Yet it works with the verbs POST and GET. Have you any idea please?

Thank you !

解决方案

According to: http://net.tutsplus.com/tutorials/php/working-with-restful-services-in-codeigniter-2/ we should consult https://github.com/philsturgeon/codeigniter-restserver/blob/master/application/libraries/REST_Controller.php#L544 to see that this method:

/**
 * Detect method
 *
 * Detect which method (POST, PUT, GET, DELETE) is being used
 * 
 * @return string 
 */
protected function _detect_method() {
  $method = strtolower($this->input->server('REQUEST_METHOD'));

  if ($this->config->item('enable_emulate_request')) {
    if ($this->input->post('_method')) {
      $method = strtolower($this->input->post('_method'));
    } else if ($this->input->server('HTTP_X_HTTP_METHOD_OVERRIDE')) {
      $method = strtolower($this->input->server('HTTP_X_HTTP_METHOD_OVERRIDE'));
    }      
  }

  if (in_array($method, array('get', 'delete', 'post', 'put'))) {
    return $method;
  }

  return 'get';
}

looks to see if we've defined the HTTP header HTTP_X_HTTP_METHOD_OVERRIDE and it uses that in favor of the actual verb we've implemented on the web. To use this in a request you would specify the header X-HTTP-Method-Override: method (so X-HTTP-Method-Override: put) to generate a custom method override. Sometimes the framework expects X-HTTP-Method instead of X-HTTP-Method-Override so this varies by framework.

If you were doing such a request via jQuery, you would integrate this chunk into your ajax request:

beforeSend: function (XMLHttpRequest) {
   //Specify the HTTP method DELETE to perform a delete operation.
   XMLHttpRequest.setRequestHeader("X-HTTP-Method-Override", "DELETE");
}
