有没有办法将字符串数组作为变量传递给服务器端的Xquery脚本？

declare variable $strings as xs:string* external;

import com.tencentcloudapi.common.Credential;
import com.tencentcloudapi.common.profile.ClientProfile;
import com.tencentcloudapi.common.profile.HttpProfile;
import com.tencentcloudapi.common.exception.TencentCloudSDKException;
import com.tencentcloudapi.tci.v20190318.TciClient;
import com.tencentcloudapi.tci.v20190318.models.SubmitAudioTaskRequest;
import com.tencentcloudapi.tci.v20190318.models.SubmitAudioTaskResponse;

public class XQueryExample {
    public static void main(String[] args) {
        try {
            // 创建腾讯云API客户端
            Credential cred = new Credential("your-secret-id", "your-secret-key");
            HttpProfile httpProfile = new HttpProfile();
            httpProfile.setEndpoint("tci.tencentcloudapi.com");
            ClientProfile clientProfile = new ClientProfile();
            clientProfile.setHttpProfile(httpProfile);
            TciClient client = new TciClient(cred, "ap-guangzhou", clientProfile);

            // 设置外部变量的值
            String[] strings = {"string1", "string2", "string3"};
            String stringsValue = String.join(",", strings);

            // 构造XQuery脚本
            String xquery = "declare variable $strings as xs:string* external; " +
                            "for $s in $strings " +
                            "return $s";

            // 构造请求
            SubmitAudioTaskRequest req = new SubmitAudioTaskRequest();
            req.setLang("en");
            req.setScript(xquery);
            req.setParams("{\"strings\":\"" + stringsValue + "\"}");

            // 发送请求并获取响应
            SubmitAudioTaskResponse resp = client.SubmitAudioTask(req);

            // 处理响应
            System.out.println(resp.getResults());

        } catch (TencentCloudSDKException e) {
            System.out.println(e.toString());
        }
    }
}
