图片音视频过滤有好多方法,我这里就不一一介绍了,这篇文章只是简单介绍一下我在项目中使用阿里云oss滤网过滤的步骤

1.所遇问题:

1.图片视频鉴别时要设置textScanRequest.setUriPattern(uri);否则会报msg=[scene] is not support

2.内容安全内容检测API服务接入地址为:http://green.cn-shanghai.aliyuncs.com(上海)或http://green.cn-hangzhou.aliyuncs.com(杭州)

3.通信协议:内容安全内容检测API服务仅支持使用HTTP协议发送请求

4.所有接口仅支持HTTP POST方法发送请求

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包请前往https://help.aliyun.com/knowledge_detail/50170.html下载

2.设置公共请求参数

参考文档:

域名目前只支持"cn-hangzhou"和"cn-hangzhou"

// 请替换成你自己的accessKeyId、accessKeySecret

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

// 内容安全内容检测API服务接入地址为:http://green.cn-hangzhou.aliyuncs.com

DefaultProfile.addEndpoint(需要检测的文件名, 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); // 所有接口仅支持HTTP

// POST方法发送请求，这种方式下请求参数需要包含在请求的URL中

textScanRequest.setEncoding("UTF-8");// 请求及返回结果都使用UTF-8字符集进行编码

textScanRequest.setRegionId(域名);

 

3.方法调用

 

参考文档: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;

}
