Go - Api.Route.Patch()

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.NewRoute("/hello").Patch(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)
  }
}

Examples

Register a handler for PATCH requests

api.NewRoute("/hello").Patch(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.NewRoute("/hello/:name").Patch(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/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()`
  api.NewRoute("/public").Patch(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.NewRoute("/hello/:name").Patch(handler.ComposeHttpMiddleware(authMiddleware, handleRequest))

  if err := nitric.Run(); err != nil {
    fmt.Println(err)
  }
}

Access the request body

The PATCH request body is accessible using ctx.Request.Data().

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.NewRoute("/hello").Patch(func(ctx *handler.HttpContext, next handler.HttpHandler) (*handler.HttpContext, error) {
    data := ctx.Request.Data()

    ctx.Response.Body = data

    return next(ctx)
  })

  if err := nitric.Run(); err != nil {
    fmt.Println(err)
  }
}
