我一直在使用codeigniter进行开发并利用输出类(https://www.codeigniter.com/user_guide/libraries/output.html)来轻松发送正确的状态代码,标头和json响应。
但是,在尝试调试我已经有一段时间的问题之后,我意识到set_status_header函数实现了RFC 2616(https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html)中的状态代码,但没有实现RFC中定义的其他状态代码6585(https://tools.ietf.org/html/rfc6585)。这意味着我无法发送429(请求太多)状态代码。
是否有支持此功能的输出类的更新版本,或者我应该使用php的header()函数来处理这个问题?
答案 0 :(得分:0)
决定使用http_response_code()并仍然使用输出类,所以我的代码如下所示:
http_response_code(429);
return $this->output
->set_header("Retry-After: " . $resp['retry_after'])
->set_content_type('application/json')
->set_output($json_result);
这很好,只是有点烦人,它与正常情况不同:
return $this->output
->set_status_header('401')
->set_content_type('application/json')
->set_output($json_result);

您可以通过在application / core中创建MY_Output.php来扩展核心输出类,并覆盖set_status_header()
。
MY_Output.php
class MY_Output extends CI_Output {
public function __construct() {
parent::__construct();
}
public function set_status_header($code = 200, $text = '') {
// copied helper function set_status_header() code from system/core/Common.php
if (is_cli())
{
return;
}
if (empty($code) OR ! is_numeric($code))
{
show_error('Status codes must be numeric', 500);
}
if (empty($text))
{
is_int($code) OR $code = (int) $code;
// Add your status codes/text in this array below
$stati = array(
100 => 'Continue',
101 => 'Switching Protocols',
200 => 'OK',
201 => 'Created',
202 => 'Accepted',
203 => 'Non-Authoritative Information',
204 => 'No Content',
205 => 'Reset Content',
206 => 'Partial Content',
300 => 'Multiple Choices',
301 => 'Moved Permanently',
302 => 'Found',
303 => 'See Other',
304 => 'Not Modified',
305 => 'Use Proxy',
307 => 'Temporary Redirect',
400 => 'Bad Request',
401 => 'Unauthorized',
402 => 'Payment Required',
403 => 'Forbidden',
404 => 'Not Found',
405 => 'Method Not Allowed',
406 => 'Not Acceptable',
407 => 'Proxy Authentication Required',
408 => 'Request Timeout',
409 => 'Conflict',
410 => 'Gone',

413 => 'Request Entity Too Large',
414 => 'Request-URI Too Long',
415 => 'Unsupported Media Type',
416 => 'Requested Range Not Satisfiable',
417 => 'Expectation Failed',
422 => 'Unprocessable Entity',
429 => 'Too Many Requests',
500 => 'Internal Server Error',
501 => 'Not Implemented',
502 => 'Bad Gateway',
503 => 'Service Unavailable',
504 => 'Gateway Timeout',
505 => 'HTTP Version Not Supported'
);
if (isset($stati[$code]))
{
$text = $stati[$code];
}
else
{
show_error('No status text available. Please check your status code number or supply your own message text.', 500);
}
}
if (strpos(PHP_SAPI, 'cgi') === 0)
{
header('Status: '.$code.' '.$text, TRUE);
}
else
{
$server_protocol = isset($_SERVER['SERVER_PROTOCOL']) ? $_SERVER['SERVER_PROTOCOL'] : 'HTTP/1.1';
header($server_protocol.' '.$code.' '.$text, TRUE, $code);
}
return $this;
}
}
