At the last DIRAC users' workshop two teasers were shown for HTTP services: But even given that information (and release notes for 7.3 and 8.0) as well as the documentation, I am still lacking. BTW: Do you have a secret URL for each DIRAC server that has descriptions of the HTTP API it supports? (e.g. like automatically done by FastAPI) Context: I would like to make a "zero dependency" DIRAC client |

Hi, This of course assumes that the server you are submitting to has the TornadoJobManager service up and running, and the rights to submit. |

Luke is talking about the GridPP one, which is still on v7r2 and doesn't have the TornadoJobManager. |

Yes, if Luke is a member of dteam, then he can use the DIRAC certification setup for test. If that's the case you can guide him through the various links. You would need to add him manually to the CS/Registry of lbcertifdirac70. |

We've been trying to find ways to connect to the GridPP diracdev and certifdirac. For certif, we tried and selected the certifdirac - is that not enough? Can you please point us to documentation on how to choose the target dirac instance? For our submission tests, we give different URLs (essentially a curl): → always querying lbcertifdirac. @fstagni we are also getting with the above. params = {"method": "submitJob", "jobDesc": jdl}Is the method OK? What format should |

Coming back to what @kreczko posted here, is there an example of a submission test anywhere? |

I usually test with import json
import requests
jdl="""
JobName = "DIRAC_no-client-test";
Executable = "/bin/ls";
Arguments = "-ltrA";
StdOutput = "std.out";
StdError = "std.err";
OutputSandbox = {"std.out","std.err"};
Owner = "fstagni";
OwnerGroup = "dteam_user";
"""
def _query(url, params):
capath="/etc/grid-security/certificates"
cert="/tmp/x509up_u49429"
with requests.post(url, data=params, cert=cert, verify=capath) as r:
return r.text
def submit_job(server, jdl):
url=f"https://{server}:8443/WorkloadManagement/JobManager"
params = {
"method": "submitJob",
"args": json.dumps([jdl])
}
return _query(url, params)
def get_jobs(server):
url=f"https://{server}:8443/WorkloadManagement/JobMonitoring"
params = {
"method": "getJobs"
}
return _query(url, params)
if __name__ == "__main__":
server = "lbcertifdirac70.cern.ch"
#result = submit_job(server, jdl)
result = get_jobs(server)
# result = get_files(server)
print(result)You should of course set your "Onwer" and "OwnerGroup" |

Aha! So that's the secret: We've been also trying with jdl = {
"JobName": "DASK_DIRAC",
"Executable": "/bin/ls",
"Arguments": "-ltrA",
"StdOutput": "std.out",
"StdError": "std.err",
"OutputSandbox": ["std.out","std.err"]
}:D OK, your example looks very doable, thanks! |

Hello, We're currently waiting to be able to submit jobs via HTTP to https://diracdev.grid.hep.ph.ic.ac.uk:8443/DIRAC/. |

dirac-configurewon't overwrite an existingdirac.cfg, so make sure you don't have one in place to start with.
