(I am a complete beginner when it comes to any back-end development so I apologise if any terms are used wrong)
I have some javascript controlling a canvas game and I have a prolog planner which can solve the game. I am now trying to connect the two and have set up a flask server which can successfully call prolog, get the correct plan and send it back to the javascript. I am really struggling with getting the right inputs from the javascript.
Javascript:
var state = {
state : "[stone(s1),active(s1), stone(s2), in(app2,s2), unlocked(app2)]"
}
stone2.on('click',function(){
$.ajax({
type: 'POST',
contentType: 'application/json',
data: state,
dataType: 'json',
url:'http://localhost:5000/next_move',
success:function(data, textStatus, jqXHR){
console.log(data);
alert(JSON.stringify(state)); //making sure I sent the right thing
}
});
});
Flask server
//variables I use in the query at the moment
state = "[stone(s1),active(s1), stone(s2), in(app2,s2), unlocked(app2)]"
goal = "[in(app1,s1),in(app1,s2)]"
@app.route('/next_move', methods=['POST'])
def get_next_step():
own_state = request.json
r = own_state['state']
output = subprocess.check_output(['sicstus','-l','luger.pl','--goal','go('+state+','+goal+').'])
//I would like to use the string I got from my browser here
stripped = output.split('\n')
return jsonify({"plan": stripped})
//the correct plan is returned
I have seen the other questions regarding this, in fact the attempt I posted is from flask request.json order, but I keep getting 400 (BAD REQUEST). I'm guessing flask changed since then? I know it sends the json correctly because if I don't try to touch it I get the success message in my browser, so it is purely my inability to access its fields or to find any examples.
