RestTemplate摘要认证

RestTemplate摘要认证

模拟Postman Authorization下Digest Auth(摘要认证)类型的认证方式

• 引入依赖

<dependency>
	<groupId>org.apache.httpcomponents</groupId>
	<artifactId>httpclient</artifactId>
	<version>4.5.12</version>
</dependency>

• 工具方法代码如下：

/**
     *
     * @param http_url 目标API
     * @param method 请求方法
     * @param headers
     * @param params
     * @param askUsername 用户名
     * @param askPwd 密码
     * @param host 目标IP
     * @param port 端口号
     * @param clazz
     * @param uriParams
     * @param <T>
     * @Description 摘要认证
     * @return
     */
    public static <T> ResponseEntity<T> getResponseEntityWithDigestAuth(String http_url, HttpMethod method,HttpHeaders headers,Object params, String askUsername, String askPwd, String host, int port,Class<T> clazz, Map<String, ?> uriParams) {
    
    
        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(new AuthScope(host, port, AuthScope.ANY_REALM),
                new UsernamePasswordCredentials(askUsername, askPwd));
        CloseableHttpClient httpclient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();

        RestTemplate restTemplate = new RestTemplate(new HttpComponentsClientHttpRequestFactory(httpclient));
        //支持中文编码
        restTemplate.getMessageConverters().set(1,
                new StringHttpMessageConverter(Charset.forName("UTF-8")));

        MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");
        headers.setContentType(type);
        headers.add("Accept", MediaType.APPLICATION_JSON.toString());
        HttpEntity<Object> entity = new HttpEntity<>(params, headers);
        return restTemplate.exchange(http_url, method, entity, clazz, uriParams);
    }

• 测试类代码：

String host="127.0.0.1";
int port = 8083;
String http_url = basicUrl+askForHelpUrl+"/0";

HttpHeaders headers = new HttpHeaders();
MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");
headers.setContentType(type);
headers.add("Accept", MediaType.APPLICATION_JSON.toString());

List<TaskForm> ticketList = new ArrayList<>();
ResponseEntity<Map> responseEntity = RestClient.getResponseEntityWithDigestAuth(http_url,HttpMethod.GET,headers,null,askUsername,askPwd,host,port,Map.class,new HashMap<>());
LinkedHashMap map = (LinkedHashMap) responseEntity.getBody();
