Thanks to all for your suggestions.
To Guillaume : I searched about the $http.get function and I wrote this
function to test if all goes well (I think I've tried it before) :
var getItinerary2=function(){
$http.get("
http://localhost:5000/viaroute?loc=47.3654647,0.6822917&loc=47.3905003,0.6920979&compression=false
"
.success(function(data, status, headers, config) {
console.log(data);
}).
error(function(data, status, headers, config) {
console.log("error");
});
};
Then I call it when I press Submit but the error function is triggered (the
browser console prints "error").
Am I doing something wrong?
To Patrick : I will take a look at the JS file to find what could be
helpful. But, to be clear, what I'm trying to do is send a query to the
OSRM server and get back the response in the backend, in my script, not
directly in frontend, as I want to extract some information from the output.
To Emil : I saw the Cucumber Suite in the OSRM project but those are
precomputed tests, with known responses to the requests. In my case, I will
run tests on a large map (OSM file size : 122 Mo) with random locations
pairs inside the area.
