java如何调用api接口

import java.net.http.HttpClient;
import java.net.URI;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

HttpClient client = HttpClient.newHttpClient();

URI uri = URI.create("https://example.com/api/v1/users");
HttpRequest request = HttpRequest.newBuilder()
    .uri(uri)
    .GET()
    .build();

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

int statusCode = response.statusCode();
String body = response.body();

import java.net.http.HttpClient;
import java.net.URI;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

public class GitHubApiExample {

    public static void main(String[] args) throws Exception {
        String token = "YOUR_ACCESS_TOKEN";

        HttpClient client = HttpClient.newHttpClient();
        URI uri = URI.create("https://api.github.com/user");
        HttpRequest request = HttpRequest.newBuilder()
            .uri(uri)
            .header("Authorization", "Bearer " + token)
            .GET()
            .build();

        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
        if (response.statusCode() == 200) {
            System.out.println(response.body());
        }
    }
}
