Sample waypoint to use in the directions service

[Kodextor]

I have been trying to use directions service with waypoints, but wasn't able to. Could someone please help me out with a sample waypoints array using location coordinates to pass to the directions().

Have you tried something like the example query in the docs here:
https://developers.google.com/maps/documentation/directions/?csw=1#Waypoints
?

You can pass either pipe separated textual destinations or lat,lng.

I tried calling the url directly... I will try to check this later and will let you know... Thanks though..

Hi!, i am trying to use the directions services with waypoints. The origin and destination are the same address and then i have two more address in an array with location like this:
var WayPoints = [{location: recogida },{location: destino}];
Where recogida and destino are both adresses.
When i call the function and i passed the waypoints array as 6th argument, appears like the directions service is not using the waypoints, because i receive a response without waypoint_order and the overview_polyline is only the origin and destination point (are the same). Is working ok?

@leandroz the direction function has changed:
https://github.com/moshen/node-googlemaps/blob/master/lib/googlemaps.js#L148

if you can provide a test for your case we can look into the issue

[leandroz]

The problem is with the function buildUrl, stringify and how you have to pass the arguments waypoints to Google Maps.
Here is the url example from Google Maps documentation:
http://maps.googleapis.com/maps/api/directions/json?origin=Boston,MA&destination=Concord,MA&waypoints=Charlestown,MA|Lexington,MA&sensor=false

See that each waypoints is separated by |, but stringify escaped an array like:

querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' })
// returns
'foo=bar&baz=qux&baz=quux&corge='

If you prove the test with waypoints it will fail.
Thats the problem.

I think this is the same issue as #49

I can see a possible confusion arising when people think waypoints is an array, whereas passing a string will make it work.

Have I understood the problem correctly @leandroz ?

Hi @fabriziomoscon !
I am passing the waypoints like this

[{location: LatLngOrigin}, {location: LatLngDestination }]

What is the proper way to do it?

[leandroz]

LatLngOrigin + "|" + LatLngDestination

Is the right way?

[fabriziomoscon]

Google expects waypoints as a string of pipe separated locations. An the library doesn't have any conversion for the input you pass.

Please pass something similar to:

var waypoints = "Charlestown,MA|Lexington,MA";
