## 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();
