如何在Android中使用HTTP POST与“application/octet-stream”？（微软认知视频）

Question

我想使用Android中的视频认知服务。Microsoft提供的示例在C#中使用。视频功能是向服务器发送URL，所以我认为在Android中使用HTTP POST发送URL是可能的。

您可以尝试这样的方法来发送用于认知服务面部检测的图像文件。使用org.apache.httpcomponents：：httpclient：

    @Test
    public void testSendBinary() throws MalformedURLException {
        File picfile = new File("app/sampledata/my_file.jpeg");
        if (!picfile.exists()) throw new AssertionError();


        HttpClient httpclient = HttpClients.createDefault();

        try {
            URIBuilder builder = new URIBuilder("https://westcentralus.api.cognitive.microsoft.com/face/v1.0/detect");

            builder.setParameter("returnFaceId", "true");
            builder.setParameter("returnFaceLandmarks", "false");

            URI uri = builder.build();
            HttpPost request = new HttpPost(uri);
            request.setHeader("Content-Type", "application/octet-stream");
            request.setHeader("Ocp-Apim-Subscription-Key", "***");

            // Request body
            request.setEntity(new FileEntity(picfile));

            HttpResponse response = httpclient.execute(request);
            HttpEntity entity = response.getEntity();

            if (entity != null) {
                System.out.println(EntityUtils.toString(entity));
            }
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
