Summary
HTTP GET and POST request methods are two of the most popular HTTP methods that are used to transfer data from clients to servers. This chapter provides an in-depth understanding of how the GET and POST request methods are used to transfer data using asynchronous requests. We then proceeded to look at cross-origin resource issues and how can we resolve them. Next, we studied the JSONP implementation on the client-side as well as on the server-side.
Concerning cross-domain asynchronous requests, we used the exception of the <script> tag to perform our JSONP asynchronous script calls to fetch the data from a different domain. In the next chapter, we will be learning about debugging JSON using various client-side tools.
