.NET - Api.Route.Post()

Register a handler for HTTP POST requests to the route.

using Nitric.Sdk;
var route = Nitric.Api("main").Route("/customers");
route.Post(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 POST requests

using Nitric.Sdk;
var route = Nitric.Api("main").Route("/customers");
route.Post(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.Post((context, next) => {
var user = context.Req.PathParams["userId"];
// Validate the user identity
if (user != "1234")
{
context.Res.Text($"User {user} is unauthorised");
context.Res.Status = 403;
// Return prematurely to end the middleware chain.
return context;
}
// Call next to continue the middleware chain.
return next(context);
}, (context, next) => {
var user = context.Req.PathParams["userId"];
context.Res.Text($"Creating {user}");
return next(context);
}
);
Nitric.Run();

Access the request body

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

using Nitric.Sdk;
var api = Nitric.Api("main").Route("/customers");
route.Post(context => {
var body = context.Req.Json<Dictionary<string, string>>();
// parse, validate and store the request payload...
});
Nitric.Run();
