Surfing the Net

- [Instructor] Hi and welcome back.…In the previous video, we started building a search UI…using asynchronous HTTP request to update our interface…based on data returned from the server.…We want to find real books based on the user's search query.…In this video, we'll replace our dummy data…with real search results based on input from the user.…We'll start by updating our backend…to fetch results from the classify2 API.…Next we'll decode the XML response data…into our search result struct.…Finally, we'll encode the search results into JSON…to return to the front-end.…

For this feature, we'll use a book classification library…called classify2.…The Classify API has a single endpoint,…which we'll use to perform our search…and eventually get the classification information…for individual books.…In our main.go file,…let's create a new function called search,…which takes in a search query string…and returns a list of search results and an error.…Let's define two variables at the top of this function,…one for the response and one for any errors we encounter.…
