调用外部接口

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("type", "type");
map.add("code", "code");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(map, headers);
String url = "http://......";
ResponseEntity<byte[]> entity = new TestRestTemplate()
        .postForEntity(url, request, byte[].class);
assertEquals(HttpStatus.OK, entity.getStatusCode());
byte[] body = entity.getBody();
log.info("获取响应body:" + body);
String bodyStr = new String(body,"utf-8");
log.info("获取bodyStr:" + bodyStr);
