SpringBoot使用Resttemplate进行Basic认证登录和Restful接口调用

直接贴代码

(推荐)方式一：使用RestTemplateBuilder自动配置

import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.web.client.RestTemplateBuilder;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.client.RestTemplate;@Configurationpublic class RestTemplateConfig { @Autowired private RestTemplateBuilder restTemplateBuilder; @Bean public RestTemplate restTemplate(){ return restTemplateBuilder.basicAuthorization("admin","admin").build(); }}

@RestController
public class Test {

@Autowired
private RestTemplate restTemplate;

@RequestMapping(value = "/test")
private String getRestResponse() {
String url ="http://192.168.17.8:6080/service/public/v2/api/service/1";
try {
return restTemplate.getForObject(url, String.class);
} catch(Exception ex) {
return ex.toString();
}
}

方式二：复杂

import org.apache.commons.codec.binary.Base64;import org.springframework.http.HttpEntity;import org.springframework.http.HttpHeaders;import org.springframework.http.HttpMethod;import org.springframework.http.ResponseEntity;import org.springframework.web.client.RestTemplate;public class TestRanger { private static final String EXPECTED_MIME_TYPE = "application/json"; static String rangerBaseUrl = "http://192.168.17.8:6080"; public static void getPolicyByName() { String url = rangerBaseUrl + "/service/public/v2/api/service/1"; String plainCreds = "admin:admin"; byte[] plainCredsBytes = plainCreds.getBytes(); byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes); String base64Creds = new String(base64CredsBytes); RestTemplate restTemplate = new RestTemplate(); HttpHeaders headers = new HttpHeaders(); headers.add("Authorization", "Basic " + base64Creds); headers.add("Content-Type","application/json"); HttpEntity<String> entity = new HttpEntity<String>(headers); ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, entity, String.class); String str = response.getBody(); System.out.println(str); } public static void main(String[] args) { getPolicyByName(); }}
