Object Storage Service:Error handling

Example of handling exceptions

The following code provides an example on how to handle exceptions:

try {
    // Perform operations on OSS such as object upload.
    ossClient.putObject(...);
} catch (OSSException oe) {
    System.out.println("Caught an OSSException, which means your request made it to OSS, "
            + "but was rejected with an error response for some reason.");
    System.out.println("Error Message: " + oe.getErrorMessage());
    System.out.println("Error Code:       " + oe.getErrorCode());
    System.out.println("Request ID:      " + oe.getRequestId());
    System.out.println("Host ID:           " + oe.getHostId());
} catch (ClientException ce) {
    System.out.println("Caught an ClientException, which means the client encountered "
            + "a serious internal problem while trying to communicate with OSS, "
            + "such as not being able to access the network.");
    System.out.println("Error Message: " + ce.getMessage());
} finally {
    if (ossClient != null) {
        ossClient.shutdown();
    }
}
            

ClientException

A ClientException indicates an exception that occurs when a client sends a request or transmit data to OSS. For example, a ClientException is returned when a request is sent under poor network conditions. A ClientException is also returned when an I/O exception occurs during object upload.

OSSException

OTSException: indicates a server exception that arises from the resolution of a server error message. A ServiceException includes the error code and message returned by OSS so that you can identify and resolve the error.

OSSException involves the following error information:
