Thank you. That was the key!

I think the issue is you have the second argument (grant_type=client_
credentials) as the data for the post, and then the json=... argument
also as data for the post.
The API for post() is that it either takes the data as the second argument
to the function, or as a keyword argument data or a keyword argument
json . It has to be only one of those options.

Hi there,
I have very little experience with Julia and want to try whether it fits
my needs. I want to connect to a Neo4j database and send a Cypher statement
with Julia, see
http://neo4j.com/docs/stable/cypher-intro-applications.html .
The authorization works fine, but I could not manage to add the *json
*keyword
(or *data*).
using Requests, HttpCommon, Codecs
db_key = neo4j
db_secret = mypasswd
# create authentication
function enc_credentials(db_key::String, db_secret::String)
bearer_token_credentials =
$(encodeURI(db_key)):$(encodeURI(db_secret))
return(base64(bearer_token_credentials))
end
response = post(URI(http://localhost:7474/db/data/transaction/commit;),
grant_type=client_credentials;
headers = {Authorization = Basic
$(enc_credentials(db_key,db_secret)), Content-Type =
application/json},
json = {statements=[{statement=CREATE (p:Person
{name:{name},born:{born}}) RETURN p,parameters={name=Keanu
Reeves,born=1964}}]})
println(response)
This results in
ERROR: unrecognized keyword argument json
