Springboot RestTemplate请求token

Springboot RestTemplate可以通过以下方式请求token：

1. 创建一个RestTemplate对象

RestTemplate restTemplate = new RestTemplate();

2. 定义请求参数

MultiValueMap<String, String> map= new LinkedMultiValueMap<>();
map.add("grant_type", "client_credentials");
map.add("client_id", "your_client_id");
map.add("client_secret", "your_client_secret");

3. 发送请求

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(map, headers);
ResponseEntity<String> response = restTemplate.postForEntity("https://your-auth-server.com/oauth/token", request, String.class);

4. 获取token

String token = response.getBody();
