使用 Java 发送事务时出现问题

如何解决使用 Java 发送事务时出现问题

我正在使用 Tron Api 的“https://api.shasta.trongrid.io/wallet/easytransferbyprivate”发送交易。由于出现错误，我无法在我的服务器上运行我的应用程序。

接收错误 -

{"result":{"code":"CONTRACT_VALIDATE_ERROR","message":"313a313a20457870656374656420227b222e"}}

我的 Java 请求 -

    CloseableHttpClient client = HttpClients.createDefault();
            HttpPost httpPost = new HttpPost("https://api.shasta.trongrid.io/wallet/easytransferbyprivate");
            httpPost.addHeader("privateKey","xxxxxx");
            httpPost.addHeader("toAddress",xxxxxx);
            httpPost.addHeader("amount","1000000");
            httpPost.setHeader("Accept","application/json");
            httpPost.setHeader("Content-type","application/json");
    
            CloseableHttpResponse response = client.execute(httpPost);
    
            httpentity entityData = response.getEntity();
    
            if (entityData != null && entityData.getContentLength() != 0) {
                JSONParser parser = new JSONParser();
                JSONObject responseJsonObj = (JSONObject) parser.parse(EntityUtils.toString(entityData));
        }
   }
