package com.thok.trading.server.util;

import org.springframework.http.HttpEntity;

    {
        HttpHeaders headers = new HttpHeaders();

        headers.setContentType(type);
        headers.add("Accept", MediaType.APPLICATION_JSON_UTF8.toString());
        HttpEntity<String> formEntity = new HttpEntity<String>(jsonBody, headers);

// 在spring bean中可以注入 RestTemplate，然后再调用上面的util
@Autowired
private RestTemplate restTemplate;
