Exception Handling
Last Updated：2020-08-11
BOS exceptions are prompted in the following two methods:
| Exception method | Description |
|---|---|
| BceClientException | Client exception |
| BceServerException | Server exception |
Users can obtain the exception generated by an event with try, for example:
String objectKey = "testObjectToFile";
bosclient.putObject(bucketName, objectKey, "dataFile");
File file = new File("test");
try {
bosclient.getObject(this.bucketName, objectKey, file);
} catch (BceServerException bce){
System.out.println(bce.getMessage());
} catch ( BceClientException bce){
System.out.println( bce.getMessage());
} finally {
file.delete();
}Client Exception
Client exception indicates an exception encountered when the client attempts to send a request to the BOS and transmits data. For example, when the network connection is unavailable at the time of sending request, ClientException is returned; and in case of IO exception during file upload, ClientException is also thrown.
Server Exception
When an exception occurs on the BOS server, the BOS server returns the corresponding error message to the user to locate the problem. Common server exceptions can be found in BOS Error Message Format.
