//headers & cookie
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("basecret", config.getBasecret());
headers.add("baid", config.getBaid());
List cookies = new ArrayList<>();
cookies.add("COOKIE_USER" + Strings.nullToEmpty(config.getCookie()));
headers.put(HttpHeaders.COOKIE, cookies);
postForObject和postForEntity方法的区别主要在于可以在postForEntity方法中设置header的属性,当需要指定header的属性值的时候,使用postForEntity方法。exchange方法和postForEntity类似,但是更灵活,exchange还可以调用get请求。使用这三种方法传递参数,Map不能定义为以下两种类型
Map
Map
把Map类型换成LinkedMultiValueMap后,参数成功传递到后台
MultiValueMap
MultiValueMap paramMap = new LinkedMultiValueMap();
paramMap.add("dt", "20190225");
// 1、使用postForObject请求接口
String result = template.postForObject(url, paramMap, String.class);
// 2、使用postForEntity请求接口
HttpHeaders headers = new HttpHeaders();
HttpEntity> httpEntity = new HttpEntity>(paramMap,headers);
ResponseEntity response2 = template.postForEntity(url, httpEntity, String.class);
// 3、使用exchange请求接口
ResponseEntity response3 = template.exchange(url, HttpMethod.POST, httpEntity, String.class);
如果是get请求,又想要把参数封装到map里面进行传递的话,Map需要使用HashMap,且url需要使用占位符,如下:
RestTemplate restTemplate2 = new RestTemplate();
String url = "http://127.0.0.1:8081/interact/getData?dt={dt}&ht={ht}";
// 封装参数,这里是HashMap
Map paramMap = new HashMap();
paramMap.put("dt", "20190225");
paramMap.put("ht", "10");
//1、使用getForObject请求接口
String result1 = template.getForObject(url, String.class, paramMap);
System.out.println("result1====================" + result1);
//2、使用exchange请求接口
HttpHeaders headers = new HttpHeaders();
headers.set("id", "lidy");
HttpEntity> httpEntity = new HttpEntity>(null,headers);
ResponseEntity response2 = template.exchange(url, HttpMethod.GET, httpEntity, String.class,paramMap);
//JSONObject userInfo = new JSONObject();
Map userInfo = Maps.newHashMap();
userInfo.put("phone", accountForm.getPhone());
userInfo.put("job", accountForm.getJob());
userInfo.put("email", accountForm.getEmail());
Map postBody = Maps.newHashMap();
postBody.put("userInfo", userInfo);
