Re: Use of PUT https://localhost:8181/Olog/logs/multipart REST API for creating log entries with attachments

Hi,

We are working on a new helper python library.

In the meanwhile it broadly looks like you request is correct. Can you share a copy of the log entry that is created ( the id 75 )

org.phoebus.olog.LogResource             : File FREIAlogo-v3_March19.png
not matched with attachment meta-data

While this is the issue resulting in the attachment file not being uploaded, once we see a copy of the log entry created we should have a better idea why.

Subject: Use of PUT https://localhost:8181/Olog/logs/multipart REST API for creating log entries with attachments

 

Hi,

I'm trying to write a simple python program to create an entry in the
new Olog server (API documented in
https://urldefense.com/v3/__https://urldefense.us/v3/__https:/*olog.readthedocs.io/en/latest/index.html__;!!G_uCfscf7eWS!dDgYNelpLq7ymQ7M1rIdPoepGvVQEAfQPCBtmSKeFTIOr5xieb6nu3QDLfhW7gWC1u9P52dP1-w0PfTS-T4BhX99ax7hhJoQQa75$__;Lw!!P4SdNyxKAPE!AbLdYMLNWFaAl0vaL34bvuQ4eAbD8mlrxJZEileV55LOJ9fPWCQVaCo_9erpxOiLRET043FDvZ55tULg8U0SQKs$   ).

I am using PUT https://urldefense.com/v3/__https://urldefense.us/v3/__https:/*localhost:8181/Olog/logs/multipart__;!!G_uCfscf7eWS!dDgYNelpLq7ymQ7M1rIdPoepGvVQEAfQPCBtmSKeFTIOr5xieb6nu3QDLfhW7gWC1u9P52dP1-w0PfTS-T4BhX99ax7hhOZ21DPF$__;Lw!!P4SdNyxKAPE!AbLdYMLNWFaAl0vaL34bvuQ4eAbD8mlrxJZEileV55LOJ9fPWCQVaCo_9erpxOiLRET043FDvZ55tULg2nzFLVA$   request and
all works fine for entries without any attachments. If I try to add an
attachment the entry itself is saved but saving the attachment fails.

I have found pyOlog library but it seems to be the old version written
for Glassfish and mysql architecture.

Does anybody have a python library, or at least an example program
showing how to use the new PUT
https://urldefense.com/v3/__https://urldefense.us/v3/__https:/*localhost:8181/Olog/logs/multipart__;!!G_uCfscf7eWS!dDgYNelpLq7ymQ7M1rIdPoepGvVQEAfQPCBtmSKeFTIOr5xieb6nu3QDLfhW7gWC1u9P52dP1-w0PfTS-T4BhX99ax7hhOZ21DPF$__;Lw!!P4SdNyxKAPE!AbLdYMLNWFaAl0vaL34bvuQ4eAbD8mlrxJZEileV55LOJ9fPWCQVaCo_9erpxOiLRET043FDvZ55tULg2nzFLVA$   API for creating the entries
with an attachment.  A curl command showing the use of PUT
https://urldefense.com/v3/__https://urldefense.us/v3/__https:/*localhost:8181/Olog/logs/multipart__;!!G_uCfscf7eWS!dDgYNelpLq7ymQ7M1rIdPoepGvVQEAfQPCBtmSKeFTIOr5xieb6nu3QDLfhW7gWC1u9P52dP1-w0PfTS-T4BhX99ax7hhOZ21DPF$__;Lw!!P4SdNyxKAPE!AbLdYMLNWFaAl0vaL34bvuQ4eAbD8mlrxJZEileV55LOJ9fPWCQVaCo_9erpxOiLRET043FDvZ55tULg2nzFLVA$   would also be helpful.

Below is the python code that I've used:

     api_endpoint = "https://urldefense.com/v3/__https://urldefense.us/v3/__https:/*olog-server:8181/Olog/logs/multipart__;!!G_uCfscf7eWS!dDgYNelpLq7ymQ7M1rIdPoepGvVQEAfQPCBtmSKeFTIOr5xieb6nu3QDLfhW7gWC1u9P52dP1-w0PfTS-T4BhX99ax7hhJIczIfa$__;Lw!!P4SdNyxKAPE!AbLdYMLNWFaAl0vaL34bvuQ4eAbD8mlrxJZEileV55LOJ9fPWCQVaCo_9erpxOiLRET043FDvZ55tULgp3Hr408$ "

     # Prepare log entry payload
     log_entry = {
         "owner": "dev",
         "description": "New entry using Olog/logs/multipart with one
attachment.\n",
         "level": "INFO",
         "title": "test4.py",
         "logbooks": [{"name": "test"}],
         "attachments":[
             {"id": str(uuid.uuid4()), "name": "FREIAlogo-v3_March19.png"}
         ]
     }

     # Prepare the log entry payload as JSON
     json_data = json.dumps(log_entry)
     json_filename = json.dumps({"filename": "FREIAlogo-v3_March19.png"})
     json_descr = json.dumps({"fileMetadataDescription": "image/png"})

     # Prepare the multipart encoder
     multipart_data = MultipartEncoder(
         fields={
             'logEntry': ('logEntry.json', json_data, 'application/json'),
             'files': ('filename', json_filename, 'application/json'),
             'files': ('fileMetadataDescription', json_descr,
'application/json'),
             'files': ('FREIAlogo-v3_March19.png',
open('FREIAlogo-v3_March19.png', 'rb'), 'application/octet-stream')
         }
     )

     # Set the Content-Type header with the boundary
     headers = {
         'Content-Type': multipart_data.content_type
     }
     try:
         response = requests.put(api_endpoint, headers=headers,
data="" auth=HTTPBasicAuth(username, password))
         if response.status_code == 200:
             print("Log entry created successfully.")
         else:
             print("Failed to create log entry. Status code:
{response.status_code}")
     except Exception as e:
         print("An error occurred: ",{str(e)})
