使用步骤：

1、前往百度智能云官网，注册账号并完成实名认证：https://cloud.baidu.com/

2、打开控制台：https://console.bce.baidu.com/ai/#/ai/antiporn/overview/index ，按照操作指引先领取免费资源，然后创建应用。

创建新应用：

创建成功后，会自动生成一个AppID和两个秘钥，后续需要用到这些参数来调百度服务：

3、测试

Java 示例代码

添加依赖：

<dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>3.14.9</version>
</dependency>

编写工具类：

import com.alibaba.fastjson.JSON;
import okhttp3.*;import java.io.IOException;
import java.net.URLEncoder;
import java.util.Base64;public class BaiduScanUtil {private static final OkHttpClient HTTP_CLIENT = new OkHttpClient().newBuilder().build();private static String apiKey = "你自己百度云的应用对应的API Key的值";private static String secretKey= "你自己百度云的应用对应的Secret Key的值";/*** 审核文本* @param text*/public  static Integer textScan(String text){try {MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");RequestBody body = RequestBody.create(mediaType, "text="+text);Request request = new Request.Builder().url("https://aip.baidubce.com/rest/2.0/solution/v1/text_censor/v2/user_defined?access_token=" + getAccessToken()).method("POST", body).addHeader("Content-Type", "application/x-www-form-urlencoded").addHeader("Accept", "application/json").build();Response response = HTTP_CLIENT.newCall(request).execute();String responseBody = response.body().string();System.out.println(responseBody);//响应结果里conclusionType的四种可能值：1.合规，2.不合规，3.疑似，4.审核失败return JSON.parseObject(responseBody).getInteger("conclusionType");} catch (IOException e) {e.printStackTrace();return 4;}}/*** 获取文件base64编码* @return base64编码信息，不带文件头* @throws IOException IO异常*/private static String getFileContentAsBase64(byte[] bytes) throws IOException {return URLEncoder.encode(Base64.getEncoder().encodeToString(bytes),"utf-8") ;}/*** 审核图片*/public static Integer imageScan(byte[] bytes){try {MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");// image 可以通过 getFileContentAsBase64("C:\fakepath\3.png") 方法获取String base64 = getFileContentAsBase64(bytes);//System.out.println(base64);RequestBody body = RequestBody.create(mediaType, "image="+base64);Request request = new Request.Builder().url("https://aip.baidubce.com/rest/2.0/solution/v1/img_censor/v2/user_defined?access_token=" + getAccessToken()).method("POST", body).addHeader("Content-Type", "application/x-www-form-urlencoded").addHeader("Accept", "application/json").build();Response response = HTTP_CLIENT.newCall(request).execute();String responseBody = response.body().string();System.out.println(responseBody);//响应结果里conclusionType的四种可能值：1.合规，2.不合规，3.疑似，4.审核失败return JSON.parseObject(responseBody).getInteger("conclusionType");} catch (IOException e) {e.printStackTrace();return 4;}}/*** 从用户的AK，SK生成鉴权签名（Access Token）** @return 鉴权签名（Access Token）* @throws IOException IO异常*/private static String getAccessToken() throws IOException{MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");RequestBody body = RequestBody.create(mediaType, "grant_type=client_credentials&client_id=" + apiKey+ "&client_secret=" + secretKey);Request request = new Request.Builder().url("https://aip.baidubce.com/oauth/2.0/token").method("POST", body).addHeader("Content-Type", "application/x-www-form-urlencoded").build();Response response = HTTP_CLIENT.newCall(request).execute();return JSON.parseObject(response.body().string()).getString("access_token");}
}
