　　直接上代码：

 1 public String transferData(String qrCode, String uuid){
 2  MultiValueMap<String, String> mulmap = new LinkedMultiValueMap<>();
 3             mulmap.add("QrCode", qrCode);
 4             mulmap.add("key", uuid);
 5             HttpHeaders headers = new HttpHeaders();
 6             headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
 7             ResponseEntity<String> result = null;
 8             HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(mulmap, headers);
 9 　　　　 //执行HTTP请求
10 　　　　 result = restTemplate.exchange(url, HttpMethod.POST, request, String.class);
11 }
