neo4j-spatial

Hi Aseem, Hi Node-Neo4j,

I'm trying to work neo4j-spatial using the db.http interface but getting an error.  My code:

var neo4j = require('neo4j');

neodb = new neo4j.GraphDatabase( {url: 'http://neo4j:pwd@localhost:7474'} );

var p = '/db/data/ext/SpatialPlugin/graphdb/addSimplePointLayer';

var h = 'Content-Type:application/json';

var b = {layer:'geom',lat:'lat',lon:'lon'};

var cb = function(err, body){ if (err){ throw err; }  console.log(body); }

//this works:  neodb.http({ method: 'GET', path: '/db/data/node/1234', body:{} }, cb);

neodb.http({ method:'POST', path:p, headers:h, body:b, raw:true }, cb)

The GET node works fine, but the POST to the SpatialPlugin fails somewhere in requestjs:

  Object.keys(obj).forEach(function (i) {

         ^

TypeError: Object.keys called on non-object

    at Function.keys (native)

I've tested the neo4j-spatial part with curl and it works:

#!/bin/bash

curl -X POST -d '{"layer":"geom","lat":"lat","lon":"lon"}' --header "Content-Type:application/json" http://localhost:7474/db/data/ext/SpatialPlugin/graphdb/addSimplePointLayer

Has anyone done this?  Any ideas?

Thanks,

Hi Matt,

The headers option is supposed to be a dictionary of key value pairs, similar to Node's native http method. Hope that helps!

Cheers,

Thanks Aseem, it's working.  So it's hdrs={  'content-type': 'application/json' }  etc.

Best,

Matt
