Error Codes

Last updated: 2022-03-31 16:27:24


The errors occurring during the use of the COS API service provided by SDK can be divided into client errors and errors returned by the server.

  • Errors returned by the server refer to the errors returned when the server processes some client requests that do not meet the requirements. For example, access to a file that does not exist, or no access to a file. For more information on the error codes returned by the server, see API Error Codes.
  • Client errors refer to network exception, IO exception during file read/write, parameter verification failure, etc.

This document describes the error codes defined by the client.
