[Projeto] Desafio: Consumendo API

Atividade 1: Consulta à API do Google Books

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.URLEncoder;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.util.Scanner;

public class GoogleBooksAPI {

    public static void main(String[] args) throws IOException, InterruptedException, URISyntaxException {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Digite o título do livro:");
        String livro = scanner.nextLine();
        scanner.close();

        // Codificando o título do livro para garantir que caracteres especiais sejam tratados corretamente na URL
        String livroEncoded = URLEncoder.encode(livro, "UTF-8");

        String url = "https://www.googleapis.com/books/v1/volumes?q=" + livroEncoded;

        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                .uri(new URI(url))
                .build();

        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());

        System.out.println("Resposta da API: " + response.body());
    }
}

Atividade 2: Consulta à API CoinGecko

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.URLEncoder;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.util.Scanner;

        Scanner scanner = new Scanner(System.in);
        System.out.println("Digite o nome da criptomoeda: ");
        String cripto = scanner.nextLine();
        scanner.close();

        String criptoEncoded = URLEncoder.encode(cripto, "UTF-8");

        String url = "https://api.coingecko.com/api/v3/simple/price?ids=" + criptoEncoded + "&vs_currencies=usd";

        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                .uri(new URI(url))
                .build();

        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());

        if (response.statusCode() == 200) {
            System.out.println("Cotação da criptomoeda: " + response.body());
        } else {
            System.out.println("Falha ao obter a cotação. Código de status: " + response.statusCode());
        }
    }
}

Atividade 3: Consulta à API do TheMealDB

import java.io.IOException;
import java.net.URI;
import java.net.URLEncoder;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.net.URISyntaxException;
import java.util.Scanner;

public class TheMealDBAPI {

    public static void main(String[] args) throws IOException, InterruptedException, URISyntaxException {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Digite o nome da receita:");
        String receita = scanner.nextLine();
        scanner.close();

        String receitaEncoded = URLEncoder.encode(receita, "UTF-8");

        String url = "https://www.themealdb.com/api/json/v1/1/search.php?s=" + receitaEncoded;

        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                .uri(new URI(url))
                .build();

        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());

        System.out.println("Informações sobre a receita: " + response.body());
    }
}
