使用 RestTemplate 发送 post 请求传递参数

注意：

post 请求的参数不能用 HashMap 封装，应该使用 MultiValueMap

写法参考

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntityString, String>> request = new HttpEntityString, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );
