用于获取访问令牌的rest-assured api的java代码应该是什么

import io.restassured.RestAssured;
import io.restassured.response.Response;

public class TokenGenerator {
    public static void main(String[] args) {
        // 设置请求的基本信息，如URL、请求头等
        RestAssured.baseURI = "https://api.example.com";
        RestAssured.basePath = "/auth/token";
        
        // 发送POST请求并获取响应
        Response response = RestAssured.given()
                .param("username", "your_username")
                .param("password", "your_password")
                .post();
        
        // 解析响应并获取访问令牌
        String accessToken = response.jsonPath().getString("access_token");
        
        // 打印访问令牌
        System.out.println("Access Token: " + accessToken);
    }
}
