Question

我对此代码感到生气。无论我是否在具有main方法的类中或在tomcat服务器上将代码作为java应用程序运行，都成功。

public class Test {

    public static void main(String[] args) {
        try { 

            String userCredentials = "USR28:YG739G5XFVPYYV4ADJVW";
            String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

            URL url = new URL("http://74.208.84.251:8221/QosicBridge/user/deposit"); 
            HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
            conn.setDoOutput(true); conn.setRequestMethod("POST"); 
            conn.setRequestProperty("Content-Type", "application/json"); 
            conn.setRequestProperty("Content-Type", "application/json");
            conn.setRequestProperty ("Authorization", basicAuth);

            String input = "{\"msisdn\":\"22997858711\",\"amount\":500,\"transref\":\"CZ21FRY3XDPGDBX7L745\",\"clientid\":\"UBHQ\"}";
            System.out.println(input); 

            OutputStream os = conn.getOutputStream(); 
            os.write(input.getBytes()); 
            os.flush(); 

            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(); 
        }
    }

}

在Tomcat服务器上运行代码时降低错误

我需要帮助以进行故障排除。在错误消息下方找到

非常感谢

我认为错误来自传递给请求的json对象。当我使用字符串对象（注释中的directInput）时，它工作正常。但是，当我使用Json对象（jsonInput）时，它给了我404错误代码。任何人都可以帮助排除故障吗？

谢谢

}

使用HttpURLConnection
