HTTP Status Code In Rails

1 minute read

Rails將這些HTTP Status定義成有意義的單字。讓我們可以在使用的時候減少因為背錯而發生錯誤的機率。

使用方式

用symbol加上單字即可取代原本的HTTP Status Code(500)

render status: 500
render status: :forbidden

這些Symbol其實定義在Rack中

原始碼 rack/utils.rb

    HTTP_STATUS_CODES = {

    # Informational
      100 => 'Continue',
      101 => 'Switching Protocols',
      102 => 'Processing',

    # Success
      200 => 'OK',
      201 => 'Created',
      202 => 'Accepted',
      203 => 'Non-Authoritative Information',
      204 => 'No Content',
      205 => 'Reset Content',
      206 => 'Partial Content',
      207 => 'Multi-Status',
      208 => 'Already Reported',
      226 => 'IM Used',

    # Redirection

      301 => 'Moved Permanently',
      302 => 'Found',

      304 => 'Not Modified',
      305 => 'Use Proxy',
      307 => 'Temporary Redirect',
      308 => 'Permanent Redirect',

    # Client Error

      426 => 'Upgrade Required',
      428 => 'Precondition Required',
      429 => 'Too Many Requests',
      431 => 'Request Header Fields Too Large',

    # Server Error
      500 => 'Internal Server Error',
      501 => 'Not Implemented',
      502 => 'Bad Gateway',
      503 => 'Service Unavailable',
      504 => 'Gateway Timeout',
      505 => 'HTTP Version Not Supported',
      506 => 'Variant Also Negotiates',
      507 => 'Insufficient Storage',
      508 => 'Loop Detected',
      510 => 'Not Extended',
      511 => 'Network Authentication Required'
    }
