我的 Java 代码出现 SSL 握手异常

我的 Java 文件

package com.mypackage.rest.client;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

public class ClientGet {

public static void main(String[] args) {

    try {

        URL url = new URL(
                "https://sandbox.tangocard.com/raas/v1.1/orders/116-101338692-28");         
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/json");
        conn.setRequestProperty("Platform_Name", "CareHeroTest");
        conn.setRequestProperty("Platform_key","8heOCfIEJHgarCraHuvqQ6vcajgu8A1r7YU4jUFLjxNtwbuREfBuO54E");
        conn.setRequestProperty("Authorization","Basic VGFuZ29UZXN0OjV4SXRyM2RNRGxFV0FhOVM0czd2WWg3a1EwMWQ1U0ZlUFBVb1paaUsvdk1mYm8zQTVCdkpMQW1ENHRJPQ==");

        if (conn.getResponseCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : " + conn.getResponseCode());
        }

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

        String output;
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {

            System.out.println(output);
        }

        conn.disconnect();

    } catch (MalformedURLException e) {

        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
}

使用Postman检索order_id信息时，同样的第三方网络服务（Tango）工作

这意味着终端服务在我提供的授权下运行良好。

平台名称 - CareHeroTest

Platform_key - 8heOCfIEJHgarCraHuvqQ6vcajgu8A1r7YU4jUFLjxNtwbuREfBuO54E

授权 - Basic VGFuZ29UZXN0OjV4SXRyM2RNRGxFV0FhOVM0czd2WWg3a1EwMWQ1U0ZlUFBVb1paaUsvdk1mYm8zQTVCdkpMQW1ENHRJPQ==

我做错了什么？因为 Tango 没有提供其他握手或证书。

【问题讨论】：

您是否将 SSL 证书导入 java keytool？
我想不需要 SSL。这应该是基本的 HTTP 事务，具有基本的访问身份验证。我想我需要执行Base64 encoding
这是一个 SSL 异常，而不是 403 Not Authorized HTTP 状态。这意味着您的请求永远不会传输到服务器。在 Postman 示例中，您显然使用了 https://，其中涉及 SSL 握手。后者失败，因为您可能没有导入证书。

【解决方案1】：

我使用了unirest API，它成功了。

package com.ansari.examples.javahttpapiclient;

import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.JsonNode;
import com.mashape.unirest.http.Unirest;

public class JavaHTTPAPIClient {
public void getQuestionsUsingUnirest() throws Exception {
    HttpResponse<JsonNode> response = Unirest.get("https://sandbox.tangocard.com/raas/v1.1/orders/116-101338692-28").
            header("accept",  "application/json").
            header("Authorization", "Basic VGFuZ29UZXN0OjV4SXRyM2RNRGxFV0FhOVM0czd2WWg3a1EwMWQ1U0ZlUFBVb1paaUsvdk1mYm8zQTVCdkpMQW1ENHRJPQ==").
            asJson();
    System.out.println(response.getBody().getObject().toString(2));
}

public static void main(String args[]) throws Exception {
    JavaHTTPAPIClient client = new JavaHTTPAPIClient();
    client.getQuestionsUsingUnirest();
}
}
