//参数中字符串中没有含有{} //样例:{"MsgRandom":407056434,"SyncOtherMachine":2,"MsgLifeTime":2592000,"OfflinePushInfo":{"Ext":"ext内容","Desc":"测试样例2021-04-10"} public static JSONObject post(String url, JSONObject postData) { LogUtils.print("info", "url", postData); JSONObject json = restTemplate.postForEntity(url, postData, JSONObject.class).getBody(); return json; } public static String get(String url) { ResponseEntity<String> responseEntity = restTemplate.getForEntity(url, String.class); return responseEntity.getBody(); } //参数中字符串中含有{} //样例:{"MsgRandom":407056434,"SyncOtherMachine":2,"MsgLifeTime":2592000,"OfflinePushInfo":{"Ext":"{\"id\":\"1377284502649556993\",\"type\":\"1\"}","Desc":"测试样例2021-04-10"} public static String getUrlWithParams(String url, Map<String, String> params) { ResponseEntity<String> responseEntity = restTemplate.getForEntity(url, String.class, params); return responseEntity.getBody(); } public static JSONObject postUrlWithParams(String url, JSONObject params) { MediaType type = MediaType.parseMediaType("application/json"); HttpHeaders headers = new HttpHeaders(); headers.setContentType(type); HttpEntity<String> formEntity = new HttpEntity<>(params.toString(), headers); ResponseEntity<JSONObject> responsebody = restTemplate.exchange(url, HttpMethod.POST, formEntity, JSONObject.class); return responsebody.getBody(); }
