Join David Gassner for an in-depth discussion in this video Reading a text file from the web, part of Learning Go.
- Go has a rich set of tools that let you work easily…with web applications and services.…The HTTP package lets you make requests…and send data to remote hosts,…and also lets you create HTTP server applications…that listen for and respond to requests.…In this demonstration, I will create an application…that requests and displays some data from a remote host.…This file, webRequest.go, has a string.…It's set to a PHP file on a server.…
I'm going to copy that, and then display it in a browser.…And I'll show that I'm receiving a JSON package,…a set of structured data in the JSON format.…And this is now the most common format…for data exchange with web services.…So here's how I'll work with it.…First, I'll go to my imports, and I'll add net/http.…Then, in my main function,…I'll use a function of the HTTP package named get.…
It's going to return a response object, and an error object.…And I'll pass in the URL string.…And then, I'll use an if statement…to evaluate the error object.…If the error isn't nil, then I'll call the panic function,…
