springboot請(qǐng)求其他服務(wù)器的http接口

使用Get方式，攜帶headers請(qǐng)求數(shù)據(jù)

//注入
@Autowired
private RestTemplate restTemplate;
@RequestMapping("/FaceInfo")
@ResponseBody
public Object ? faceInfo(String startTime,String endTime,Integer size ){
? ? String apiURL = "http://www.05un.cn/wspp/GceGroups";
? ? HttpHeaders headers = new HttpHeaders();
? ?headers.add("userId","38");
? ? // headers.set("userId","38");
? ? headers.setContentType(MediaType.APPLICATION_JSON);
? ? Map<String, Object> requestParam = new HashMap<>();
? ? HttpEntity<Map<String, Object>> request = new HttpEntity<Map<String, Object>>(requestParam, headers);
? ? ? ? ResponseEntity<String> entity2 = restTemplate.exchange(apiURL, HttpMethod.GET, request, String.class);
? ? String body = entity2.getBody();
? ? return body;
}

使用Post方式，攜帶body請(qǐng)求數(shù)據(jù)

//注入
@Autowired
