如何在Java中使用Rest-assured使用多部分文件附件？

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

public class RestAssuredExample {
    public static void main(String[] args) {
        // 设置基本的URL
        RestAssured.baseURI = "https://api.example.com";

        // 创建请求对象
        Response response = RestAssured.given()
                .multiPart("file", new File("/path/to/file.txt")) // 添加文件附件
                .post("/upload"); // 发送POST请求

        // 处理响应
        int statusCode = response.getStatusCode();
        String responseBody = response.getBody().asString();

        System.out.println("Status code: " + statusCode);
        System.out.println("Response body: " + responseBody);
    }
}
