java - 我正在尝试从 java spring boot 调用节点 api（扫描 aws），但从服务器获取 Unexpected end of file;

Question

爪哇代码

final String uri = "http://localhost:3000/scan"; 
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> result = restTemplate.postForEntity(uri, awsCredentials, String.class);

您可以在下面的 url 中查看 node js 项目（index.js，engine 方法）
