使用REST调用并进行授权的Java客户端程序

Question

我需要从Java代码中调用REST调用。

我有以下形式的证书

1. id
2. 安全密钥

提供的算法

>

获取服务器时间

使用Id、安全密钥

现在授权在下面的表格

"Authorization": "name id=Id, serverTime=serverTime, securitytoken=securitytoken"

需要一个java客户端程序使用上述授权标头调用此REST调用。

我正在得到

HTTP响应401错误。

请提供在请求表单中设置授权标头的正确方法

Name Id="Id",serverTime="2017-11-18T05:51:05",securityToken="TOKEN"

代码：

package com.rest.client;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.URL;

public class Sample {

    public final static String GATEWAY_ID = "Id";

    public final static String KEY = "Key";

    public static void main(String[] args) {

        try {

            HttpURLConnection conn;

            conn = (HttpURLConnection) new URL("https://domain/A/B/72968").openConnection();

            String serverTime = "2017-11-18T10:51:05";

            String securityToken = "TOKEN"; 

            String authorization = "Name Id=\"" + GATEWAY_ID + "\",serverTime=\"" + serverTime + "\",securityToken=\""
                    + securityToken + "\"";

            // Name Id="Id",serverTime="2017-11-18T10:51:05",securityToken="TOKEN"

            conn.addRequestProperty("Authorization", authorization); // Is Header set is correct? It should be part of Request Header. Please correct this

            int status = conn.getResponseCode();

            System.out.println(status);

            BufferedReader br = null;

            StringBuilder body = null;

            String line = "";

            br = new BufferedReader(new InputStreamReader(conn.getInputStream()));

            body = new StringBuilder();

            while ((line = br.readLine()) != null) {
                body.append(line);
            }

            System.out.println(body);

        } catch (Exception exception) {
            exception.printStackTrace();
        }
    }

}

错误：

尝试用这种方式格式化授权字符串“Basic Base64”。尝试

 authorization ="Basic "+new String(new Base64().encode(authorization.getBytes()));
    conn.setRequestProperty("Authorization", authorization);
