哪些HTTP响应代码是错误的？

Question

我想根据响应代码决定应该显示哪个模板(视图):

    $codes = 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 Time-out',
        409 => 'Conflict',
        410 => 'Gone',
        411 => 'Length Required',
        412 => 'Precondition Failed',
        413 => 'Request Entity Too Large',
        414 => 'Request-URI Too Large',
        415 => 'Unsupported Media Type',
        416 => 'Requested range not satisfiable',
        417 => 'Expectation Failed',
        500 => 'Internal Server Error',
        501 => 'Not Implemented',
        502 => 'Bad Gateway',
        503 => 'Service Unavailable',
        504 => 'Gateway Time-out',
    );

我知道2xx表明一切都很好,所以对于2xx我可以显示与请求相关的模板文件.

这是否意味着所有其他都是错误,我应该显示标准的"错误"模板？

Answer 1

4xx 客户端错误.

5xx 是服务器错误.

3xx 根本不是错误.

请参阅RFC 2616第6.1.1节(状态代码和原因短语).

您应该考虑处理418 I'm a teapot以及超文本咖啡壶控制协议.RFC 2324
