嗨，我正在努力通过java程序在netsuite中使用OAuth1.0连接netsuite RESTAPI
但我不断收到未经授权的信息
我被困在这从过去3天，没有得到任何线索来解决这个问题。
我的程序：

package com;

import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.util.Base64;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;

import org.apache.commons.lang.RandomStringUtils;

import com.squareup.okhttp.MediaType;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.RequestBody;
import com.squareup.okhttp.Response;

public final class Oauth1SigningInterceptor {

    private static String nonce;
    private static long timeStamp;
    private static String tokenSignature;

    private static String consumerKey = "1441e...";
    private static String consumerSecret = "7a72e...";
    private static String accessToken = "b6cca...";
    private static String accessSecret = "4ffb0...";

    public static void main(String[] args) throws Exception {

        createTokenBasedAttributes();
        OkHttpClient client1 = new OkHttpClient();
        MediaType mediaType1 = MediaType.parse("application/json");
        RequestBody body1 = RequestBody.create(mediaType1, "{\n\"q\": \"select * from role\"\n}");
        Request request1 = new Request.Builder()
                .url("https://TSTDRV942460.suitetalk.api.netsuite.com/services/rest/query/v1/suiteql")
                .method("POST", body1).addHeader("Prefer", "transient")
                .addHeader("Authorization",
                        "OAuth realm=\"TSTDRV942460\"," + "oauth_consumer_key=\"" + consumerKey + "\","
                                + "oauth_token=\"" + accessToken + "\","
                                + "oauth_signature_method=\"HMAC-SHA256\",oauth_timestamp=\"" + timeStamp + "\","
                                + "oauth_nonce=\"" + nonce + "\"," + "oauth_version=\"1.0\"," + "oauth_signature=\""
                                + tokenSignature + "\"")
                .addHeader("Content-Type", "application/json").addHeader("Cookie", "NS_ROUTING_VERSION=LAGGING")
                .build();

        System.out.println(request1);

        Response response1 = client1.newCall(request1).execute();

        System.out.println("response1 =>" + response1);
    }

    private static void createTokenBasedAttributes() throws Exception {
        nonce = RandomStringUtils.randomAlphanumeric(20); // unique number
        timeStamp = System.currentTimeMillis() / 1000L; // current time stamp in Unix format
        tokenSignature = computeSignature(nonce, timeStamp);
    }

    private static String computeSignature(String nonce, Long timeStamp) throws Exception {
        String baseString = "TSTDRV942460" + "&" + consumerKey + "&" + accessToken + "&" + nonce + "&" + timeStamp;
        String key = consumerSecret + "&" + accessSecret;
        return computeSHAHash(baseString, key);
    }

    private static String computeSHAHash(String baseString, String key) throws Exception {
        byte[] bytes = key.getBytes();
        SecretKeySpec mySigningKey = new SecretKeySpec(bytes, "HmacSHA256");
        try {
            Mac messageAuthenticationCode = Mac.getInstance("HmacSHA256");
            messageAuthenticationCode.init(mySigningKey);
            byte[] hash = messageAuthenticationCode.doFinal(baseString.getBytes());
            return new String(Base64.getEncoder().encode(hash));
        } catch (NoSuchAlgorithmException | InvalidKeyException e) {
            throw new Exception(e);
        }
    }

}

从 Postman 我可以连接这个成功。我在java中添加了相同的代码，只是创建了nonce、timestamp、signature运行时。但它不起作用。。。。
