Go - Api.Get()
Register an API route and set a specific HTTP GET handler on that route.
This method is a convenient short version of Api.Route.Get()
import (
"fmt"
"github.com/nitrictech/go-sdk/handler"
"github.com/nitrictech/go-sdk/nitric"
)
func main() {
api, err := nitric.NewApi("public")
if err != nil {
return
}
api.Get("/hello", func(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
ctx.Response.Body = []byte("Hello World")
return next(ctx)
})
if err := nitric.Run(); err != nil {
fmt.Println(err)
}
}
Parameters
- Name
match
- Required
- Required
- Type
- string
- Description
The path matcher to use for the route. Matchers accept path parameters in the form of a colon prefixed string. The string provided will be used as that path parameter's name when calling middleware and handlers. See create a route with path params.
- Name
middleware
- Required
- Required
- Type
- HttpMiddleware
- Description
The middleware function to use as the handler for HTTP requests. If you want to compose more than one middleware use
handler.ComposeHttpMiddleware
.

Examples
Register a handler for GET requests
api.Get("/hello", func(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
ctx.Response.Body = []byte("Hello World")
return next(ctx)
})
Create a route with path params
api.Get("/hello/:name", func(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
name := ctx.Request.PathParams()["name"]
ctx.Response.Body = []byte("Hello " + name)
return next(ctx)
})
Create a route with no method security
import (
"fmt"
"github.com/nitrictech/go-sdk/handler"
"github.com/nitrictech/go-sdk/nitric"
)
func main() {
defaultOidcRule := nitric.OidcRule("user", "https://example-issuer.com", []string{"YOUR-AUDIENCES"})
secureApi, err := nitric.NewApi(
"secure",
nitric.WithSecurity(defaultOidcRule([]string{"products:read"})))
if err != nil {
return
}
// Override the APIs security requirements with `WithNoMethodSecurity()`
secureApi.Get("/public", func(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
// Handle request
return next(ctx)
}, nitric.WithNoMethodSecurity())
if err := nitric.Run(); err != nil {
fmt.Println(err)
}
}
Chain functions as a single method handler
When multiple functions are provided they will be called as a chain. If one succeeds, it will move on to the next. This allows middleware to be composed into more complex handlers.
import (
"fmt"
"github.com/nitrictech/go-sdk/handler"
"github.com/nitrictech/go-sdk/nitric"
)
func authMiddleware(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
// Perform auth validation
return next(ctx)
}
func handleRequest(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
name := ctx.Request.PathParams()["name"]
ctx.Response.Body = []byte("Hello " + name)
return next(ctx)
}
func main() {
api, err := nitric.NewApi("private")
if err != nil {
return
}
api.Get("/hello/:name", handler.ComposeHttpMiddleware(authMiddleware, handleRequest))
if err := nitric.Run(); err != nil {
fmt.Println(err)
}
}
