@Component

        @Autowired
        private ObjectMapper objectMapper;

        @Autowired
        private RestTemplate restTemplate;
        @Override
        public void run(String... args) throws Exception {
            String currenty = "szhj_doge";
            String str = this.restTemplate.getForObject("https://www.xunibi.biz/trade/index_json/market/szhj_doge?t=" + Math.random(), String.class);
            JsonNode jsonNode = this.objectMapper.readTree(str);
            JsonNode menu = jsonNode.get("menu");
            JsonNode szhjDoge = menu.get(currenty);
            String price = szhjDoge.get("price").asText();
            System.out.println(price);
        }
    }
The execution on

windows can get the price normally, but it cannot be obtained in Aliyun"s centos

.

windows as shown in figure

centos

I hope someone can help me solve it.


check Aliyun's centos network to see if the external network is accessible.
