SDK Common Results (SDK for Python)

Function

Each time an ObsClient related API is called (excluding ObsClient.createSignedUrl and ObsClient.createPostSignature), an SDK common result object will be returned. You can obtain the HTTP status code from this object to check whether the operation is successful.

Parameter Description

**Table 1** GetResult
Parameter	Type	Description
status	int	Explanation: HTTP status code Value range: A status code is a group of digits ranging from 2xx (indicating successes) to 4xx or 5xx (indicating errors). It indicates the status of a response. For more information, see Status Code. Default value: None
reason	str	Explanation: Reason description. Default value: None
errorCode	str	Explanation: Error code returned by the OBS server. If the value of status is less than 300, this parameter is left blank. Default value: None
errorMessage	str	Explanation: Error message returned by the OBS server. If the value of status is less than 300, this parameter is left blank. Default value: None
requestId	str	Explanation: Request ID returned by the OBS server Default value: None
indicator	str	Explanation: Error indicator returned by the OBS server. Default value: None
hostId	str	Explanation: Requested server ID. If the value of status is less than 300, this parameter is left blank. Default value: None
resource	str	Explanation: Error source (a bucket or an object). If the value of status is less than 300, this parameter is left blank. Default value: None
header	list	Explanation: Response header list, composed of tuples. Each tuple consists of two elements, respectively corresponding to the key and value of a response header. Default value: None
body	object	Explanation: Result content returned after the operation is successful. If the value of status is larger than 300, this parameter is left blank. The value varies with the API being called. For details, see Bucket-Related APIs (SDK for Python) and Object-Related APIs (SDK for Python). Default value: None

The following is an example of a successful returned result:

{
    'status': 200,
    'reason': 'OK',
    'body': {
	...The details are omitted here.
    },
    'requestId': '000001************B5512',
    'header': [...The header is omitted.]
}

Code Examples

try:
    resp = obsClient.getObject('bucketname', 'objectname', loadStreamInMemory=True) 
          
    if resp.status < 300: 
        print('requestId:', resp.requestId)
        # Obtain the object content.
        print('buffer:', resp.body.buffer) 
        print('size:', resp.body.size) 
    else: 
        print('errorCode:', resp.errorCode) 
        print('errorMessage:', resp.errorMessage)
except:
    import traceback
    print(traceback.format_exc())

In a binary download, if loadStreamInMemory is set to True, the object content is contained in the body.buffer parameter in the returned result.
