How can I update a work item VIA api?
I am trying to update the tags field, removing one tag and adding another. I followed the instructions on this wiki
had no luck i am getting response: 400.
code:
print(self._req.headers)
URL= self._url+'oslc/workitems/' + str(workitem_id) + '?oslc.properties=dc:subject'
request headers
{'User-Agent': 'python-requests/2.20.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': 'text/json', 'Connection': 'keep-alive', 'Content-Type': 'application/json; charset=utf-8', 'If-Match': '"987654331-1234-1234-1234-123456789"'}
Do you guys have a working python example of updating a work item VIA api
One answer
Did you do authentication step first? The first time you need to authenticate, then you can do GET, from that you can obtain the E-Tag to put in If-Match from the headers and then use that in the PUT.
I'm afraid I don't have a python example. If you can use curl, there are some useful examples.
The below doesn't do partial updates, but it might be easier to get something working which updates the whole work item first.
#First I run this script to authenticate
URL=https://servername:9443/ccm/resource/itemName/com.ibm.team.workitem.WorkItem/1
COOKIES=./cookies.txt
USER=xxxx
PASSWORD=yyyy
HOST="https://servername:9443/ccm"
curl -k -c $COOKIES "$HOST/authenticated/identity"
curl -k -L -b $COOKIES -c $COOKIES -d j_username=$USER -d j_password=$PASSWORD "$HOST/authenticated/j_security_check"
COOKIES=./cookies.txt
USER=xxxx
PASSWORD=yyyy
HOST="https://servername:9443/ccm"
curl -k -c $COOKIES "$HOST/authenticated/identity"
curl -k -L -b $COOKIES -c $COOKIES -d j_username=$USER -d j_password=$PASSWORD "$HOST/authenticated/j_security_check"
#Then do a GET to obtain the work item in xml (or json)
curl -D - -k -b cookies.txt -o "wi1.xml" -H "Content-Type: application/rdf+xml" -H "Accept: application/rdf+xml " -H "OSLC-Core-Version: 2.0" $URL
#Because I put -D - it will output headers to standard output.. and this gives me the E-Tag value
