调用百度长视频审核API（）使用java语言，提交视频审核任务，接收视频审核结果，拉取视频审核写一段示例代码

以下是使用Java语言调用百度长视频审核API的示例代码：

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import org.apache.commons.codec.binary.Base64;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

import java.io.File;
import java.io.IOException;

public class VideoAuditExample {

    private static final String API_URL = "https://aip.baidubce.com/rest/2.0/solution/v1/video_censor/v2/user_defined";

    private static final String API_KEY = "your_api_key";

    private static final String SECRET_KEY = "your_secret_key";

    public static void main(String[] args) throws IOException {
        String filePath = "/path/to/your/video/file.mp4";
        String result = submitVideoAuditTask(filePath);
        System.out.println(result);
    }

    private static String submitVideoAuditTask(String filePath) throws IOException {
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost(API_URL);

        String accessToken = getAccessToken(API_KEY, SECRET_KEY);
        httpPost.setHeader("Content-Type", "multipart/form-data");
        httpPost.setHeader("Authorization", "Bearer " + accessToken);

        FileBody fileBody = new FileBody(new File(filePath));
        StringBody parameters = new StringBody("{\"scenes\": [\"antiporn\", \"terror\"], \"antiporn\": {\"interval\": 5}}, ContentType.APPLICATION_JSON");

        HttpEntity entity = MultipartEntityBuilder.create()
                .addPart("video", fileBody)
                .addPart("params", parameters)
                .build();

        httpPost.setEntity(entity);

        CloseableHttpResponse response = httpClient.execute(httpPost);
        HttpEntity responseEntity = response.getEntity();
        String result = EntityUtils.toString(responseEntity);

        JSONObject jsonObject = JSON.parseObject(result);
        String taskId = jsonObject.getString("taskId");

        // 拉取视频审核结果
        result = getVideoAuditResult(taskId, accessToken);

        return result;
    }

    private static String getVideoAuditResult(String taskId, String accessToken) throws IOException {
        String url = "https://aip.baidubce.com/rest/2.0/solution/v1/video_censor/v2/user_defined/result?taskId=" + taskId;
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost(url);

        httpPost.setHeader("Content-Type", "application/json");
        httpPost.setHeader("Authorization", "Bearer " + accessToken);

        CloseableHttpResponse response = httpClient.execute(httpPost);
        HttpEntity responseEntity = response.getEntity();
        String result = EntityUtils.toString(responseEntity);

        JSONArray jsonArray = JSON.parseArray(result);
        JSONObject jsonObject = jsonArray.getJSONObject(0);
        String status = jsonObject.getString("status");

        if ("SUCCESS".equals(status)) {
            return result;
        } else {
            return "审核失败";
        }
    }

    private static String getAccessToken(String apiKey, String secretKey) throws IOException {
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost("https://aip.baidubce.com/oauth/2.0/token");

        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");

        String authString = apiKey + ":" + secretKey;
        byte[] authBytes = authString.getBytes();
        String encodedAuthString = new String(Base64.encodeBase64(authBytes));

        StringBody parameters = new StringBody("grant_type=client_credentials&client_id=" + apiKey + "&client_secret=" + secretKey, ContentType.APPLICATION_FORM_URLENCODED);

        HttpEntity entity = MultipartEntityBuilder.create()
                .addPart("grant_type=client_credentials&client_id=" + apiKey + "&client_secret=" + secretKey, parameters)
                .build();

        httpPost.setEntity(entity);

        CloseableHttpResponse response = httpClient.execute(httpPost);
        HttpEntity responseEntity = response.getEntity();
        String result = EntityUtils.toString(responseEntity);

        JSONObject jsonObject = JSON.parseObject(result);
        String accessToken = jsonObject.getString("access_token");

        return accessToken;
    }
}

其中，`API_KEY`和`SECRET_KEY`需要替换成你的百度API Key和Secret Key。`filePath`需要替换成你要审核的视频文件路径。该示例代码提交视频审核任务后，会返回任务ID，然后通过任务ID去拉取视频审核结果。
