Imagga 图像识别技术API调用方法

imagga api调用有多种方式，demo中用的是java调用，其调用方式必须先调用"https://api.imagga.com/v1/content"请求获得一个content Id ，然后将该Id作为参数再调用"https://api.imagga.com/v1/tagging?content="才能的到返回的tag 数据，具体调用方式如下：

################################# 该方法为执行方法 ###########################################

public static volatile String apiContent = "https://api.imagga.com/v1/content";

public static volatile String apiTagging = "https://api.imagga.com/v1/tagging?content=";

public static ImaggaTagsResultModel getTagsFromImaggaServerWithHttpClient(String authorization,File binaryFile) throws Exception {

//调用获取上传图片的 content Id的restful，返回HttpResponse

        HttpResponse response = uploadFileWithHttpClient(apiContent, authorization, binaryFile);

        Map<String, Object> json = getHttpResponseJsonMap(response);

        Map<String, Object> idMap = (Map<String, Object>) ((List) json.get("uploaded")).get(0);

        String contentId = idMap.get("id").toString();
        log.info("ContentId: "+contentId);

        if (contentId != null) {

            Thread.sleep(1000);//7243f057f824e1ad290c72aae740b2c6

            String taggingUrl = apiTagging + contentId;

            HttpClient client = HttpClientBuilder.create().build();

            HttpGet request = new HttpGet(taggingUrl);

            request.setHeader(HttpHeaders.AUTHORIZATION, authorization);

            HttpResponse taggingResponse  = client.execute(request);

            String taggingJson = HttpUtils.getHttpClientResult(taggingResponse);

            log.info("TaggingJson: "+taggingJson);

            Gson gson = new Gson();

            ImaggaTagsResultModel result = gson.fromJson(taggingJson, ImaggaTagsResultModel.class);

            return result;

        }

        Thread.sleep(1000);//7243f057f824e1ad290c72aae740b2c6

        return null;  
    }

################################# 获取上传图片的 content Id 的Restful###########################################

public static HttpResponse uploadFileWithHttpClient(String url, String authorization, File targetFile ) throws IOException{

     HttpClient client = HttpClientBuilder.create().build();

      HttpPost httppost = new HttpPost(url);

      httppost.setHeader("authorization", authorization);

      FileBody fileBody = new FileBody(targetFile);

      MultipartEntityBuilder builder = MultipartEntityBuilder.create();

      builder.addPart(targetFile.getName(), fileBody);

      HttpEntity entity = builder.build();

      httppost.setEntity(entity);

      HttpResponse response = client.execute(httppost);

      return response;

    }

################################# 将HttpResponse转为Map对象###########################################

 public static Map<String, Object> getHttpResponseJsonMap(HttpResponse response) throws Exception {

        String json = HttpUtils.getHttpClientResult(response);

        Gson gson = new Gson();

        Map<String, Object> map = gson.fromJson(json, HashMap.class);

        return map;

    }
