Tips on establishing a connection to the remote server using JSON data format

I have been attempting to connect JSON data through AJAX but have encountered numerous issues such as cross-domain problems and receiving port non-existence. Can someone suggest an alternative method for posting data to the server using the getJSON method or any other working approach?

requestNumber = JSONRequest.post(
    "https://json.penzance.org/request",
    {
        user: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="8eeae1edfae1fceff8effaeffccef7efe6e1e1a0ede1e3">[email protected]</a>",
        t: "vlIj",
        zip: 94089,
        forecast: 7
    },
    function (requestNumber, value, exception) {
        if (value) {
            processResponse(value);
        } else {
            processError(exception);
        }
    }
);

In this function, I am not experiencing any success. Can anyone provide assistance with this issue?

Answer №1

Utilizing AJAX to retrieve JSON data should not pose insurmountable challenges; it is a widely used method for fetching data from external servers. I recommend addressing any issues with AJAX rather than exploring alternative methods.

Below are some suggestions on how to resolve the two issues you mentioned.

Addressing Same Origin Policy

To overcome the same origin policy hurdle, consider looking into CORS (Cross Origin Resource Sharing):

http://en.wikipedia.org/wiki/Cross-origin_resource_sharing

http://enable-cors.org/

Alternatively, explore JSON-P (although CORS is generally recommended over JSON-P for security purposes)

http://en.wikipedia.org/wiki/JSONP

Resolving Non-Existent Receiving Port

If you encounter the issue of a non-existent receiving port, it could indicate that the request was sent to an incorrect address or that the receiving server is misconfigured.
