This example demonstrates testing Go HTTP handlers using the standard library’s `net/http/httptest` package. It shows a homepage handler that returns content from a repository interface and a post handler that echoes a form value, with tests verifying their responses. The code uses `httptest.NewRecorder` to capture responses, `http.NewRequest` to build requests, and URL-encoded form data for POST parameters. A test repository replaces the real implementation to provide deterministic output.

golang web examples

This example demonstrates basic HTTP server patterns in Go, showing how to build routes with public and private endpoints. It uses the standard `net/http` package to define handlers for the root, `/post`, and `/json` routes, with middleware wrappers like `BasicAuth`, `GetOnly`, and `PostOnly` controlling access. The code includes functions for basic authentication, request method filtering, and JSON responses via `encoding/json`. A shell script runs `curl` commands to test the server’s behavior.

Http example with Go

This Go example demonstrates a simple HTTP server with three route handlers that return plain-text responses. The code uses the `net/http` package's `NewServeMux` router to map URL paths (`/hello`, `/world`, and a catch-all `/`) to handler functions, each writing a short string via `io.WriteString` to the `http.ResponseWriter`. The server listens on port 8000, and the main function prints a startup message. No external libraries are used beyond Go's standard library.

Simple Golang HTTPS/TLS Examples

This example demonstrates multiple approaches to implementing HTTPS and TLS in Go, showing both a standard HTTP server with `http.ListenAndServeTLS` and lower-level TLS connections using `crypto/tls`. It includes separate server and client implementations that communicate over TLS, with the server handling connections concurrently via goroutines. The code also shows certificate generation commands using OpenSSL and a hardened TLS configuration with specific cipher suites and minimum protocol version for achieving a perfect SSL Labs score.

This example demonstrates HTTP request and response interactions with the httpbin.org testing service, showing how GET and POST requests return JSON payloads with different parameters. It uses raw HTTP/1.1 protocol calls to the /anything endpoint, with visual separation of request headers, response headers, and body content. The gist displays three scenarios: a simple GET without parameters, a GET with a URL query string, and a POST with a custom body, all returning metadata about the request in JSON format. The code relies on standard HTTP libraries to make these calls, though the implementation details are not shown in the file itself.

hapi testing

This example shows a Hapi server that fetches the Google homepage, converts its HTML to a PDF document, and returns it as the HTTP response. The server defines a single GET route on the root path, which chains together the `request-promise` library for the external HTTP request with the `html-pdf` library to generate the PDF buffer. The handler asynchronously resolves the PDF buffer and replies with the correct `application/pdf` content type, demonstrating a server-side data conversion and delivery pipeline.

Gist 1074953

This example demonstrates server-side request benchmarking and logging through real-time socket events. The code uses the `GO.aop` aspect-oriented programming module to intercept controller execution, measuring rendering time with the `GO.time` vendor library. Each HTTP request triggers two socket emissions: one reports the page render duration via a benchmark message, while the other logs Apache-style visit details including the URL and user-agent. Data is transmitted through `GO.Socket.emit` with timestamps and unique identifiers generated by `GO.utils.uid`.

Testa

This example demonstrates a simple interactive event-handling pattern for HTML links. Two links, each bound to a separate instance of a JavaScript `Obj` constructor, respond to clicks by logging a greeting to the console. The code relies on native DOM APIs such as `document.getElementById` and the `onclick` property, while closures capture each instance’s current `word` property. The first link logs “Hola testa” after the property is reassigned, while the second logs “Hello testa,” illustrating how per-instance state persists. No external libraries or data sources are used; the behavior is purely client-side.

Serve static file with golang

This example demonstrates a minimal Go web server that serves static files from a local directory. It uses the `net/http` package’s `FileServer` handler to map the root URL path to the folder `D:/dev/static`, while `http.ListenAndServe` binds the server to port 5555. The code also logs a startup message via the `log` package. No dynamic data processing or client-side visualization is involved; the server simply delivers any requested file (HTML, images, etc.) over HTTP.
