使用RestTemplate Rest Rest API的基本认证

Question

我正在使用spring的mvc（基于注释）和java。我需要在我的应用程序中执行其他API。我对API和REST都很新。在我的休息申请中需要做的所有基本配置是什么？我打算使用“RestTemplate” 如何使用RestTemplate进行基本身份验证（在URL标头中传递用户名和密码）？请任何人帮助我。

在此先感谢。

Answer 1

您必须添加authetication头（其中Base64是例如从org.apache.commons.codec.binary.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：

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

POST请求，您可以通过HttpEntity标准postForObject()方法

而不是“@”你必须把“：”

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();
