百度提供了免費的文本內容審核 響應時間在1秒左右
第一步：在百度開發(fā)賬號中創(chuàng)建應用，獲取配置信息

/*** 百度圖片審核配置信息*/ public class BaiduSensitiveConfig {/*** 1.app id*/public static final String APP_ID = "";/*** 2.api key*/public static final String API_KEY = "";/*** 3.secret key*/public static final String SECRET_KEY = "";/*** 4.文字認證接口*/public static final String WORD_URL="https://aip.baidubce.com/rest/2.0/antispam/v2/spam";}

第二部創(chuàng)建應用對象 采用單例模式

/*** 實例化百度處理客戶端*/ private static class SingletonHolder{private final static AipContentCensor instance= new AipContentCensor(BaiduSensitiveConfig.APP_ID, BaiduSensitiveConfig.API_KEY, BaiduSensitiveConfig.SECRET_KEY); } public static AipContentCensor getClientInstance(){return SingletonHolder.instance; }

第三步

/** * 敏感詞過濾 工具類*/ public class BaiduSensitiveWord {//調用兩種方式對比速度public static void main(String[] args) {String content = "asdfv";DecimalFormat df=new DecimalFormat("0.00");long start= System.currentTimeMillis();System.out.println(check(content));long end = System.currentTimeMillis();System.out.println("耗時"+df.format((float)(end-start)/1000)+"s");long start2= System.currentTimeMillis();System.out.println(checkBySDK(content));long end2 = System.currentTimeMillis();System.out.println("耗時"+df.format((float)(end2-start2)/1000)+"s");}/*** 百度檢查文字輸入是否合格* 調api接口實現(xiàn)* @param content* @return*/public static boolean check(String content){HttpClient client = HttpClientBuilder.create().build();String url = BaiduSensitiveConfig.WORD_URL+"?access_token="+AuthService.getAuth();HttpPost post = new HttpPost(url);JSONObject response = null;try {StringEntity s = new StringEntity("content="+content);s.setContentEncoding("UTF-8");s.setContentType("application/x-www-form-urlencoded");post.setEntity(s);HttpResponse res = client.execute(post);//200if(res.getStatusLine().getStatusCode() == HttpStatus.SC_OK){String result = EntityUtils.toString(res.getEntity());// 返回json格式：System.out.println(result);response = JSONObject.parseObject(result);}} catch (Exception e) {throw new RuntimeException(e);}if (response.containsKey("result")){int result = JSONObject.parseObject(response.get("result").toString()).getInteger("spam");if (result==0) {return true;}}return false;}/*** 百度驗證文件合法* 調SDK實現(xiàn)* @return*/public static boolean checkBySDK(String content){AipContentCensor client = BaiduSensitiveImg.getClientInstance();org.json.JSONObject response = client.antiSpam(content, null);System.out.println(response.toString());if (response.has("result")){int result = JSONObject.parseObject(response.get("result").toString()).getInteger("spam");if (result==0) {return true;}}return false;} }

注：調用api接口時需要獲取access_token，方法在百度文檔中可以找到。

package com.mwztc.utils.baidu;import com.mwztc.config.BaiduSensitiveConfig; import org.json.JSONObject;import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; import java.util.List; import java.util.Map;/*** 獲取百度云接口調用token*/ public class AuthService {/*** 獲取權限token* @return 返回示例：* {* "access_token": "24.460da4889caad24cccdb1fea17221975.2592000.1491995545.282335-1234567",* "expires_in": 2592000* }*/public static String getAuth() {// 官網獲取的 API Key 更新為你注冊的String clientId = "百度云應用的AK";// 官網獲取的 Secret Key 更新為你注冊的String clientSecret = "百度云應用的SK";return getAuth(BaiduSensitiveConfig.API_KEY, BaiduSensitiveConfig.SECRET_KEY);}/*** 獲取API訪問token* 該token有一定的有效期，需要自行管理，當失效時需重新獲取.* @param ak - 百度云官網獲取的 API Key* @param sk - 百度云官網獲取的 Securet Key* @return assess_token 示例：* "24.460da4889caad24cccdb1fea17221975.2592000.1491995545.282335-1234567"*/public static String getAuth(String ak, String sk) {// 獲取token地址String authHost = "https://aip.baidubce.com/oauth/2.0/token?";String getAccessTokenUrl = authHost// 1. grant_type為固定參數(shù)+ "grant_type=client_credentials"// 2. 官網獲取的 API Key+ "&client_id=" + ak// 3. 官網獲取的 Secret Key+ "&client_secret=" + sk;try {URL realUrl = new URL(getAccessTokenUrl);// 打開和URL之間的連接HttpURLConnection connection = (HttpURLConnection) realUrl.openConnection();connection.setRequestMethod("GET");connection.connect();// 獲取所有響應頭字段Map<String, List<String>> map = connection.getHeaderFields();// 遍歷所有的響應頭字段for (String key : map.keySet()) {System.err.println(key + "--->" + map.get(key));}// 定義 BufferedReader輸入流來讀取URL的響應BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));String result = "";String line;while ((line = in.readLine()) != null) {result += line;}/*** 返回結果示例*/System.err.println("result:" + result);JSONObject jsonObject = new JSONObject(result);String access_token = jsonObject.getString("access_token");return access_token;} catch (Exception e) {System.err.printf("獲取token失敗！");e.printStackTrace(System.err);}return null;}}
