postman请求是可以的
源码如下
/** * * @param unbindMultiMerchantDtoList */ @Override public void unbind(List<UnbindMultiMerchantDto> unbindMultiMerchantDtoList) { String url = analysisPlatformUrl + "/Interface/Paas.aspx?Command=UnbindMultiMerchant"; try { HttpHeaders requestHeaders = new HttpHeaders(); requestHeaders.add("Content-Type", "application/json"); ObjectMapper objectMapper = new ObjectMapper(); log.info("<==微信群聊消息 {}", objectMapper.writeValueAsString(unbindMultiMerchantDtoList)); HttpEntity<List<UnbindMultiMerchantDto>> requestEntity = new HttpEntity<>(unbindMultiMerchantDtoList, requestHeaders); ResponseEntity<Object> response = restTemplate.exchange(url, HttpMethod.POST, requestEntity, Object.class); log.info("<==商家解绑结果 {}", JSON.toJSONString(response)); } catch (Exception ex) { log.error("<== 商家解绑失败: {} ", JSON.toJSONString(unbindMultiMerchantDtoList), ex); } }
将返回体的Object换String就可以了
