func handler(ctx *web.Context) { if !isValidRequest(ctx) { ctx.Abort(400, "Bad Request") return } // Do something if request is valid }
func middleware(next web.Handler) web.Handler { return func(ctx *web.Context) { // Do some authentication or validation checks if !isAuthenticated(ctx) { ctx.Abort(401, "Unauthorized") return } next(ctx) } }In this example, we have a middleware function that performs some authentication or validation checks before allowing the request to be handled by the next handler in the chain. If the checks fail, we call `ctx.Abort` to return a 401 Unauthorized error and stop the execution of the current request. Overall, the "Context Abort" function in the "github.com/hoisie/web" library is a useful tool for handling errors and stopping the execution of HTTP requests when necessary.
