HTTP Status Codes (SDK for Java)

The OBS server complies with the HTTP standard. After an API is called, the OBS server returns a standard HTTP status code. The following tables list the categories of HTTP status codes and the common HTTP status codes in OBS.

  • Categories of HTTP status codes

    Category

    Description

    1XX

    Informational response. A request is received by the server and the server requires the requester to continue the operation. This category is usually invisible to the client.

    2XX

    Success. The operation is received and processed successfully.

    3XX

    Redirection. Further operations to complete the request are required. This category is usually invisible to the client.

    4XX
