http.cat VS arduinolibs

Cats for other HTTP status codes can be found (or not found :-)) one level up

https://http.cat

Whenever we request data or services from a server, it can respond with status codes represented by numbers. You've probably heard of "404" which means "not found", but there are others like "201 - Created" and "500 - Internal Server Error." During one of my mentoring sessions, I was given a website that showcased all these status codes with kitten memes and a brief description. It was fantastic and helped me grasp each one of those statuses better.

import { Module, OnModuleInit } from '@nestjs/common' import { HttpModule, HttpService } from '@nestjs/axios' import { CatApi } from './cat-api.service' @Module({ imports: [ HttpModule.register({ // line A timeout: 1_000, maxRedirects: 2, baseURL: 'https://http.cat', }), ], providers: [ { provide: CatApi, useExisting: HttpService, // line B } ], exports: [CatApi], // line C }) export class CatApiModule implements OnModuleInit { constructor(private readonly httpService: HttpService) {} onModuleInit() { this.httpService.axiosRef.defaults.headers.common['Accept'] = 'application/json' } }

Secondly, to calculate the signature using HMAC-SHA1, you need to use the Crypto library, which is not included in the default Arduino libraries. You can download it from the Arduino Library Manager or directly from the GitHub repository (https://github.com/rweather/arduinolibs/tree/master/libraries/Crypto). Once you have installed the library, you can use the Crypto.hmacSha1() method to calculate the signature. Here's an updated version of the _get_signature() function:

ASCON as well as several others are implemented for embedded here: https://github.com/rweather/arduinolibs

Here's an example using the library you used: https://github.com/rweather/arduinolibs/blob/master/libraries/Crypto/examples/TestSHA3_256/TestSHA3_256.ino
