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```java HttpEntity 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```java LinkedHashMap 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);```
