oss濾網圖片音視頻過濾(1)內容檢測

圖片音視頻過濾有好多方法,我這裏就不一一介紹了,這篇文章只是簡單介紹一下我在項目中使用阿里雲oss濾網過濾的步驟

1.所遇問題:

1.圖片視頻鑑別時要設置textScanRequest.setUriPattern(uri);不然會報msg=[scene] is not support

2.內容安全內容檢測API服務接入地址爲:http://green.cn-shanghai.aliyuncs.com(上海)或http://green.cn-hangzhou.aliyuncs.com(杭州)

3.通訊協議:內容安全內容檢測API服務僅支持使用HTTP協議發送請求

4.全部接口僅支持HTTP POST方法發送請求

2.所需jar包

aliyun-java-sdk-core-3.0.7.jar
aliyun-java-sdk-green-3.0.0.jar
aliyun-sdk-oss-2.6.0-javadoc.jar
aliyun-sdk-oss-2.6.0-sources.jar
aliyun-sdk-oss-2.6.0.jar

以上jar包請前往https://help.aliyun.com/knowledge_detail/50170.html下載

2.設置公共請求參數

參考文檔: https://help.aliyun.com/document_detail/53413.html?spm=5176.doc53412.6.556.OPla1v

域名目前只支持"cn-hangzhou"和"cn-hangzhou"

// 請替換成你本身的accessKeyId、accessKeySecret

IClientProfile profile = DefaultProfile.getProfile(域名, accessKeyId,accessKeySecret);

// 內容安全內容檢測API服務接入地址爲:http://green.cn-hangzhou.aliyuncs.com

DefaultProfile.addEndpoint(須要檢測的文件名, 域名, "Green", "green.cn-hangzhou.aliyuncs.com");

 

IAcsClient client = new DefaultAcsClient(profile);

 

TextScanRequest textScanRequest = new TextScanRequest();

textScanRequest.setAcceptFormat(FormatType.JSON); // 指定api返回格式

textScanRequest.setContentType(FormatType.JSON);

textScanRequest.setMethod(com.aliyuncs.http.MethodType.POST); // 全部接口僅支持HTTP

// POST方法發送請求，這種方式下請求參數須要包含在請求的URL中

textScanRequest.setEncoding("UTF-8");// 請求及返回結果都使用UTF-8字符集進行編碼

textScanRequest.setRegionId(域名);

 

3.方法調用

 

參考文檔:https://help.aliyun.com/document_detail/53423.html?spm=5176.doc28440.6.564.NWZQ2p

List<Map<String, Object>> tasks = new ArrayList<Map<String, Object>>();
Map<String, Object> task1 = new LinkedHashMap<String, Object>();
task1.put("dataId", UUID.randomUUID().toString());
task1.put("content", text);
tasks.add(task1);
JSONObject data = new JSONObject();
data.put("scenes", Arrays.asList("antispam"));
data.put("tasks", tasks);

textScanRequest.setContent(data.toJSONString().getBytes("UTF-8"), "UTF-8", FormatType.JSON);

try {
HttpResponse httpResponse = client.doAction(textScanRequest);

if (httpResponse.isSuccess()) {
JSONObject jo = JSON.parseObject(new String(httpResponse.getContent(), "UTF-8"));
Gson gson = new Gson();
TextBean fromJson = gson.fromJson(jo.toString(), TextBean.class);
List<TextBean.DataBean> data2 = fromJson.getData();
for (int i = 0; i < data2.size(); i++) {
TextBean.DataBean dataBean = data2.get(i);
List<TextBean.DataBean.ResultsBean> results = dataBean.getResults();
for (int j = 0; j < results.size();) {
TextBean.DataBean.ResultsBean resultsBean = results.get(j);
String suggestion = resultsBean.getSuggestion();
if (suggestion.equals("pass")) {
return true;
} else {
return false;
}
}
}

} else {
return false;
}

} catch (ServerException e) { e.printStackTrace(); } catch (ClientException e) { e.printStackTrace(); } return true; }
