How run delete queries via GraphDB REST API-CodePudding

I'm trying to run DELETE queries from the GraphDB REST API with Python requests module, without luck.

SELECT queries with requests.get() work fine:

query = "http://localhost:7200/repositories/myreponame?name=&infer=true&sameAs=false&query=SELECT ?s ?p ?o
WHERE { 
    ?s ?p ?o .
}
"
response = requests.get(query, headers = {"Authorization" : token})

But whenever I switch to a DELETE query, it won't work.

If I use the DELETE query with requests.get() I get this error:

query = "http://localhost:7200/repositories/myreponame?name=&infer=true&sameAs=false&query=DELETE {
    	?s ?p ?o .
}
WHERE { 
    ?s ?p ?o .
}
"

MALFORMED QUERY: Encountered " "delete" "DELETE "" at line 1, column 1.
Was expecting one of:
    "base" ...
    "prefix" ...
    "select" ...
    "construct" ...
    "describe" ...
    "ask" ...

If I use the DELETE query with requests.delete() instead, I get:

Repository delete error: query supplied with request

What am I doing wrong?

I'm accessing the API with admin privileges, so that is not the issue.

EDIT: Based on UninformedUser's comment I tried the switching to a POST request, and modifying the URL from query to update. Also added the appropriate content type as described here:

query = "http://localhost:7200/repositories/myreponame?name=&infer=true&sameAs=false&update=DELETE {
    	?s ?p ?o .
}
WHERE { 
    ?s ?p ?o .
}
"
response = requests.post(query, headers = {"Authorization" : token, "Content-Type": "application/x-www-form-urlencoded"})

Now getting the following error:

Missing parameter: query

CodePudding user response：

Turns out that I was missing a specific requirement from GraphDB: for updates it's necessary to append /statements right after the repository ID:

query = "http://localhost:7200/repositories/myreponame/statements?name=&infer=true&sameAs=false&update=DELETE {
    	?s ?p ?o .
}
WHERE { 
    ?s ?p ?o .
}
"
response = requests.post(query, headers = {"Authorization" : token, "Content-Type": "application/x-www-form-urlencoded"})
