I am trying to download data from a specific URL within a web page (specifically, a Google API). The issue is that the API only returns JSON data and I need to use "jsonp" for cross-domain access. However, when making a "jsonp" request, I encounter an error: "Uncaught SyntaxError: Unexpected token :".
While I could set up a backend server as a proxy, I'm wondering if there is a client-side solution to this problem. Any ideas?
When data is made public and Google has enabled CORS on their servers through the Access-Control-Allow-Origin: * header, a simple HTTP request using the XMLHttpRequest object is all that is needed.
var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://www.google.com/some.json');
xhr.onload = function(e) {
var data = JSON.parse(this.response);
console.log(data);
}
xhr.send(null);
In case the above example fails, it suggests that the data is not public and requires some form of authentication, such as OAuth2. In this scenario, utilizing the provided (backend) libraries for OAuth would be more convenient.
