data参数

大部分时间都是'Content-Type': 'application/json'，flask_appbuilder的服务中很多接口是 multipart/form-data;,

用python调用时，通常情况下

data = json.dumps({ "catalogCode":"region","pageNo": 1, "pageSize": 1000})
headers = {'Token': Token, 'Accept': 'application/json', 'Content-Type': 'application/json;charset=utf-8'}
r = requests.post(user_url, headers=headers, data=data)```form-data时需要如下data ={ "catalogCode":"region","pageNo": 1, "pageSize": 1000} headers = {'Token': Token}r = requests.post(user_url, headers=headers, data=data)但是在java中，不只是改为'Content-Type': 'multipart/form-data'还需要用MultiValueMap```javaHttpEntity entity = new HttpEntity(req.getRequestBody(), headers);HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(map, headers);
ResponseEntity response = restTemplate.exchange(url, httpMethod, entity, respTypes)
if (response != null) {int status = response.getStatusCode().value();rsp.setStatus(status);HttpHeaders rspHeaders = response.getHeaders();if (rspHeaders != null) {Map<String, String> rspHeaderMap = new HashMap<>(8);for (Map.Entry<String, List<String>> entry : rspHeaders.entrySet()) {rspHeaderMap.put(entry.getKey(), entry.getValue().toString());}rsp.setHeader(rspHeaderMap);}rsp.setBody(response.getBody());```这里要改为```javaLinkedHashMap linkedHashMap= (LinkedHashMap)req.getRequestBody();headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);MultiValueMap<String, Object> map = new LinkedMultiValueMap<>();Iterator it = linkedHashMap.entrySet().iterator();while (it.hasNext()){Map.Entry entry = (Map.Entry)it.next();map.add((String)entry.getKey(),entry.getValue());}HttpEntity<MultiValueMap<String, Object>> entity = new HttpEntity<>(map, headers);
//            HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(map, headers);ParameterizedTypeReference<BaseResponse> respTypes = new ParameterizedTypeReference<BaseResponse>() {};try {RestTemplate rt = new RestTemplate();BaseResponse response =rt.postForObject("http://127.0.0.1:8550/edit/12",entity, BaseResponse.class);```
