エラーコード

Estimated reading time: 7 minutes

REST API プロトコルでは、HTTP と JSON-RPC が使用されるため、2 つのレイヤーの状態コードを使用できます。 このページでは、エラーの様々な処理方法について説明し、主なエラーの例を示します。

概要

  • エラーコードは 0〜65535 の間で定義されています。エラーコードは 2 つの領域 (REST API システム領域とユーザー領域) に分けられます。
error code area
0 - 32767 REST API system area
32768 - 65535 user area
  • ユーザー領域は、共通領域と各サービスに分けられます。
error code area
32768 - 39999 Unused areas.
40000 - 40199 Service common areas.
40200 - 40399 System service area.
40400 - 40599 Camera service area.
40600 - 40799 videoScreen service area.
40800 - 40999 Audio service area.
41000 - 41199 avContent service area.
41200 - 41399 Recording service area.
41400 - 41599 appControl service area.
41600 - 41799 Browser service area.
42000 - 42199 accessControl service.
42200 - 42399 contentDownload service.
42400 - 42599 Encryption service.
42600 - 42799 contentSync service.
42800 - 42999 contentSync service.
43000 - 65535 A reserved area.

code Reason phrase example JSON example Explanation
Error code. This is the 1st Element of “error”. Example of the error reason message. This is the 2nd Element of “error”. Example of the “error” member’s response. This is shown in bold and italics. Explanation of the error case.

REST API の HTTP メジャーエラーコード

以下が基本方針です。

  • 元の HTTP 定義に従う
  • HTTP エラーへの対応を強制はしない

HTTP ステータスコードが 200 OK 以外の場合、HTTP サーバーが REST API プロトコルに従ってレスポンスボディを返します。 エラーコードは HTTP エラーコードと同じである必要があります。主なエラーコード以下のとおりです。

code Reason phrase example JSON example Explanation
401 Unauthorized “error”: [401, “Unauthorized”] Request requires user authentication.
403 Forbidden “error”: [403, “Forbidden”] Server understood the request, but is refusing to fulfill it. The client does not have permission to access.
404 Not Found “error”: [404, “Not Found”] For cases where the request is not matched to any supported API version.
413 Request Entity Too Large “error”: [413, “Request Entity Too Large”] The accepted body size of the client request exceeds the maximum limit.
414 Request-URI Too Long “error”: [414, “Request-URI Too Long”] The accepted URI length of the client request exceeds the maximum limit.
501 Not Implemented “error”: [501, “Not Implemented”] When the request method is not implemented on the server.
503 Service Unavailable “error”: [503, “Service Unavailable”] When the server is in a temporarily unavailable state which may occur due to other concurrent connections. (The number of maximum connections is not defined because it depends on the server.)

システムエラーコード

code Reason phrase example JSON Example Explanation

7 Illegal State “error”: [7, “Illegal State”] For cases when the server cannot handle the request at this time.
12 No Such Method “error”: [12, “No Such Method”] For cases when the requested API does not exist.
14 Unsupported Version “error”: [14, “Unsupported Version”] For cases when the requested version is not supported on the specified service.
15 Unsupported Operation “error”: [15, “Unsupported Operation”] For cases when the server cannot handle the request with respect to the specified parameters.

40006 Please contact the inquiry counter “error”: [40006, “Exxxx”] A common error code used among services to be used for general errors.
