Map Layers from JSON api

BeckBeach — Mon, 10 Apr 2017 19:56:50 GMT

Hi! I am trying to make map layers from my JSON API links. Here is my codepen, which doesn't work:

http://codepen.io/beckbeach/pen/EWqJzL

What do I need to do in order to get my links to display the data points?

It works with the CSV data layers but the client wants the layers to run from an API.

It doesn't look like the output from your url is valid json? This is what I see if I log out the value to the console.

Object {0: "h", 1: "t", 2: "t", 3: "p", 4: "s", 5: ":", 6: "/", 7: "/", 8: "w", 9: "w", 10: "w", 11: ".", 12: "v", 13: "e", 14: "r", 15: "i", 16: "z", 17: "o", 18: "n", 19: "c", 20: "l", 21: "o", 22: "u", 23: "d", 24: "p", 25: "l", 26: "a", 27: "t", 28: "f", 29: "o", 30: "r", 31: "m", 32: ".", 33: "c", 34: "o", 35: "m", 36: "/", 37: "s", 38: "e", 39: "r", 40: "v", 41: "i", 42: "c", 43: "e", 44: "-", 45: "s", 46: "t", 47: "a", 48: "t", 49: "u", 50: "s", 51: "/", 52: "a", 53: "p", 54: "i", 55: "2", 56: ".", 57: "p", 58: "h", 59: "p", 60: "?", 61: "s", 62: "t", 63: "a", 64: "t", 65: "u", 66: "s", 67: "=", 68: "t", 69: "r", 70: "u", 71: "e", 72: "&", 73: "d", 74: "e", 75: "p", 76: "t", 77: "h", 78: "=", 79: "1", 80: "&", 81: "p", 82: "r", 83: "o", 84: "j", 85: "e", 86: "c", 87: "t", 88: "=", 89: "v", 90: "c", 91: "p", 92: "%", 93: "2", 94: "F", 95: "s", 96: "t", 97: "a", 98: "t", 99: "u"…}

I also tested it out using the esriRequest sample in the help. What is the output of your url supposed to look like?

Re: Map Layers from JSON api

Ok so that isn't what is being returned by the urls you are using. Perhaps they are missing something? Here's a sample showing how you can add data to a map - in this case we make a request to Flickr for photo info and display it on the map.
