.NET - api.route.delete()

Register a handler for HTTP DELETE requests to the route.

using Nitric.Sdk;

var route = Nitric.Api("main").Route("/customers");

route.Delete(context => {
    // Construct a response for all incoming HTTP requests
    var responseBody = new Dictionary<string, string>();
    context.Res.Json(responseBody);

    return context;
});

Nitric.Run();

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
    Middleware<HttpContext> or Func<HttpContext, HttpContext>
    Description

    One or more middleware functions to use as the handler for HTTP requests. Handlers can be sync or async.

Examples

Register a handler for DELETE requests

using Nitric.Sdk;

var route = Nitric.Api("main").Route("/customers");

route.Delete(context => {
    // Construct a response for all incoming HTTP requests
    var responseBody = new Dictionary<string, string>();
    context.Res.Json(responseBody);

    return context;
});

Nitric.Run();

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.

var route = Nitric.Api("main").Route("/customers/:userId");

route.Delete((context, next) => {
    var user = context.Req.PathParams["userId"];

    // Validate the user identity
    if (user != "1234")
    {
        context.Res.Text($"User {user} is unauthorised");
        context.Res.Status = 403;

        // Return prematurely to end the middleware chain.
        return context;
    }

    // Call next to continue the middleware chain.
    return next(context);
  }, (context, next) => {
    var user = context.Req.PathParams["userId"];

    context.Res.Text($"Deleting {user}");

    return next(context);
  }
);

Nitric.Run();

Access the request body

The DELETE request body is accessible from the ctx.req object.

using Nitric.Sdk;

var api = Nitric.Api("main").Route("/customers");

route.Delete(context => {
  var body = context.Req.Json<Dictionary<string, string>>();
  // parse, validate and store the request payload...
});

Nitric.Run();
