php – 使用Codeigniter获取PUT请求

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

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

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,看看这个方法：

/**
 * 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';
}

看看我们是否定义了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.要在请求中使用它,您将指定标头X-HTTP-Method-Override：方法(因此X-HTTP-Method-Override：put)以生成自定义方法覆盖.有时框架需要X-HTTP-Method而不是X-HTTP-Method-Override,因此这会因框架而异.

如果你是通过jQuery做这样的请求,你会把这个块集成到你的ajax请求中：

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