java阿里云图片检测同/异步sdk调用

sdk调用流程:注册阿里云账号→创建RAM子账号→子账号授权→复制子账号的AccessKey ID&Access Key Secret→sdk&api调用
阿里云RAM子账号创建、授权、api文档详情查看

注意:调用阿里云接口的时候最容易出错的俩个地方

		1.AccessKey ID&Access Key Secret
			因为阿里云是主张接口调用都是给子账号权限然后用子账号的AccessKey ID&Access Key Secret来调用接口,所有我们复制这俩个参数的时候很容易复制成我们主账号的这俩参数去了,切记一定要复制子账号的这俩参数!!
		2.权限添加
			很多时候我们所有步骤都作对了就是连不通的原因,就是子账号的权限没给,如我现在要调文本反垃圾的接口但是我没给子账号这个权限是无论如何都调不通的切记!!

阿里云不仅提供了api还提供了sdk,有了sdk我们就方便多了,阿里云帮我们封装了所有的方法我们只需要复制粘贴就能用这些接口了,但是前提得注意我上面说的一些注意事项切记嗷java阿里云sdk地址
1.同步图片检测:同步检测图片中的违规内容,实时返回检测结果。
支持检测的场景包括:图片智能鉴黄、图片暴恐涉政识别、图片广告识别、图片二维码识别、图片不良场景识别、图片logo识别。

1):同步图片检测代码如下:

/**

    @org.junit.Test

        List<Map<String, Object>> tasks = new ArrayList<Map<String, Object>>();
        Map<String, Object> task = new LinkedHashMap<String, Object>();
        task.put("dataId", UUID.randomUUID().toString());

         * ad: 图片广告
         * ocr: 文字识别
         */
        data.put("scenes", Arrays.asList("porn", "terrorism"));
        data.put("tasks", tasks);

        imageSyncScanRequest.setHttpContent(data.toJSONString().getBytes("UTF-8"), "UTF-8", FormatType.JSON);

        /**

        try {

                System.out.println(JSON.toJSONString(scrResponse, true));
                if (200 == scrResponse.getInteger("code")) {
    
    
                    JSONArray taskResults = scrResponse.getJSONArray("data");
                    for (Object taskResult : taskResults) {

                                String suggestion = ((JSONObject) sceneResult).getString("suggestion");
                                //根据scene和suggetion做相关的处理
                                //do something
                                System.out.println("scene = [" + scene + "]");
                                System.out.println("suggestion = [" + suggestion + "]");
                            }
                        } else {

                        }

                } else {
    
    
                    System.out.println("detect not success. code:" + scrResponse.getInteger("code"));
                }
            } else {
    
    
                System.out.println("response not success. status:" + httpResponse.getStatus());
            }
        } catch (ServerException e) {
    
    
            e.printStackTrace();
        } catch (ClientException e) {
    
    
            e.printStackTrace();
        } catch (Exception e) {
    
    
            e.printStackTrace();
        }
    }

2):同步图片检测结果如下:

{
    
    
	"msg":"OK",
	"code":200,
	"data":[
		{
    
    
			"msg":"OK",

					"rate":99.99,
					"suggestion":"pass",
					"label":"normal",
					"scene":"terrorism"
				}
			],
			"taskId":"imgitaNeo8XlI5fNtKt93rzT-1r9AuE",

	"requestId":"0C0A9B1C-BB89-47B8-8AB8-7FE7BA65D31D"
}
scene = [porn]
suggestion = [block]
scene = [terrorism]
suggestion = [pass]

2.异步图片检测:提交图片异步检测任务,检测图片违规或识别图片中的不良信息。

支持检测的场景包括:图片智能鉴黄、图片暴恐涉政识别、图片广告识别、图片二维码识别、图片不良场景识别、图片logo识别。

异步检测任务不会实时返回检测结果,您需要通过轮询的方式或者callback的方式获取检测结果。。
