Unexpected token : from a URL with extension . json

Question

When trying to get a JSON through the URL: http://www.cidades.ibge.gov.br/gmap/shapes/35/MU_M13_3550308_1000.json

I get a status 200 with the error:

Uncaught SyntaxError: Unexpected token :

Using AJAX as follows:

$(document).ready(function($) {
  $.ajax({
    type: "GET",
    url: "http://www.cidades.ibge.gov.br/gmap/shapes/35/MU_M13_3550308_1000.json",
    dataType: "jsonp",
    success: function(data) {
      console.log(data);
    },
    error: function(xhr, ajaxOptions, thrownError) {
      console.log(xhr.status);
      console.log(thrownError);
    }
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

What is the cause of the error?

Answer 1

The content of URL provided does not return a valid JSON. That’s why you’re having this error.

Apparently, in the specific case of your problem, looks like the quotes are missing from the keys to the items. What I would do is create an endpoint on an intermediate server that downloads the original file, treats it and returns the fixed file.
