使用RestTemplate对Rest API进行基本身份验证

Question

我正在使用带有java的spring mvc（基于注释）。我需要在我的应用程序中执行rest API。我对API和REST都很陌生。在我的Rest应用程序中需要做的所有基本配置是什么？我打算用“RestTemplate” 如何使用RestTemplate进行基本身份验证（在URL头中传递用户名和密码）？请有人帮助我。

提前致谢。

Answer 1

您必须添加验证标头（例如，来自org.apache.commons.codec.binary.Base64的Base64）：

String plainCreds = "yourUsername@yourPassword";
byte[] plainCredsBytes = plainCreds.getBytes();
byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
String base64Creds = new String(base64CredsBytes);
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);

然后将其添加到请求中：

HttpEntity<String> request = new HttpEntity<String>(headers);
ResponseEntity<YourResponseType> response = restTemplate.exchange(url, HttpMethod.GET, request, YourResponseType.class);
YourResponseType account = response.getBody();

对于POST请求，您可以将HttpEntity传递给标准postForObject()方法

代替＆＃34; @＆＃34;你必须把＆＃34;：＆＃34;

String plainCreds = "yourUsername:yourPassword";
byte[] plainCredsBytes = plainCreds.getBytes();
byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
String base64Creds = new String(base64CredsBytes);
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);

HttpEntity<String> httpEntity = new HttpEntity<String>(headers);
ResponseEntity<YourResponseType> response = restTemplate.exchange(url, HttpMethod.GET, httpEntity, YourResponseType.class);
YourResponseType account = response.getBody();
