Re: [Virtuoso-users] Submit SPARQL query with POST method

[Alfredo Serafini]

...moreover  I find useful to adopt the encoded version, more or less this
way:

$ curl -X POST \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept:text/csv" \
--data-urlencode "SELECT DISTINCT ?Concept WHERE { [] a ?Concept } LIMIT
100" \
--data-urlencode "default-graph-uri=https://example.org/mygraph; \
"http://localhost:8890/sparql;

best,
Alfredo

Re: [Virtuoso-users] Submit SPARQL query with POST method

[jerven Bolleman]

Hi Luis, Roel,

The --data section should start with query=

curl -X POST -vH "Accept:application/sparql-results+xml" --data 
"query=select distinct ?Concept where {[] a ?Concept} LIMIT 100" 
http://localhost:8890/sparql


For the rest using a response type other than HTML  is recommended
e.g. the sparql-results in xml I added.

Regards,
Jerven

Hi all,

I would like to submit queries to the SPARQL endpoint using the POST
method to avoid payload limits with GET. For some reason, Virtuoso is
not able to identify the query in the message body. An example:

$ curl -X POST -H "Accept:text/html" --data "select distinct ?Concept
where {[] a ?Concept} LIMIT 100" http://localhost:8890/sparql
Virtuoso 22023 Error The request does not contain text of SPARQL

Am I doing something wrong here? Or should I use a different method?


Try adding another header with: -H "Content-Type: application/sparql-
update".

Kind regards,
Roel Janssen
