neo4j cypher json giving http 500 server erro

问题

I need to create a few nodes in neo4j and for that I am using json and curl inside my c++ program.

This is the request and response that I get back.

About to connect() to localhost port 7474 (#0)
Trying ::1...
Connection refused
Trying 127.0.0.1...
Connected to localhost (127.0.0.1) port 7474 (#0)

         "NodeId" : "10.227.28.95",
         "NodeName" : "BLR_WAO_SARF7"
      }
   },
   "query" : "CREATE (n:Router { props }) RETRUN n"
}


HTTP/1.1 500 Server Error
Content-Type: text/html; charset=ISO-8859-1

HTTP error before end of send, stop sending

Closing connection 0

I am always getting this "500 Server Error". Is something wrong with the query?

回答1:

Look at your query:

"CREATE (n:Router { props }) RETRUN n"

It should be RETURN:

"CREATE (n:Router { props }) RETURN n"
