How to get an array as input body parameter in Foxx Application

[cagraw...@gmail.com]

Hi:
I am new to ArangoDB. I am using following controller in a Foxx App.
I am not able to get startPoints as an array. Can you provide right syntax and also, I am assuming format of data in the body should be:
["x", "y", "z"]
?

  controller.get("/executeNeighbors", function (req, res) {
    res.set("Content-Type", "text/plain; charset=utf-8");
    var mygraph = 'mygraph_c';
    var graph = graph_module._graph(mygraph);
    var rii = db._collection("rii_11");
    var start = req.param("startPoints"); // We load the body by the name defined later
    var query = aqlQuery`RETURN GRAPH_NEIGHBORS("mygraph_c", ${start}, {includeData: false, direction: "outbound", maxDepth: 10000000, minDepth: 1})`;
    var cursor = db._query(query);
    res.json(cursor.toArray());
  }).bodyParam("startPoints", joi.array());

Thanks,
CP

Hi,
I don't see where you defined joi or added values to it?
Do you use jslint to check for eventual typos?

Cheers,

Hi CP,

your code looks right as far as the body is concerned. Can you check what the actual value of `start` is by logging it to the console? Try `console.log(require('util').inspect(start))` for more detailed output.

If the array value is correct, can you also check the query using the web interface to see whether it behaves as expected using the input you're providing?

Cheers,

Alan

I am attaching the entire app.js file. I took Hello-Foxx app and extended it.
Following is the response I get from the app for every type of input I have tried.

{
  "error": true,
  "code": 422,
  "errorNum": 422,
  "errorMessage": "Request body must be an array"
}

Hi again,

I just realized the route you're defining is a GET route (hence `controller.get`). The HTTP GET method does not permit a request body. You are probably trying to define a POST or PUT route (using `controller.post` or `controller.put`).

Cheers,

First time I tried using put. Foxx application wouldn't compile (sorry, I don't have exact error handy now).
I have rewritten the application to save the input collection using bulk import and now sending start and end point of each input slice. Please see attached. This version seem to work fine.
