Microsoft Face API中的“解码错误，图像格式不受支持”(“Decoding error, image format unsupported” in Microsoft Face API

Microsoft Face API中的“解码错误，图像格式不受支持”(“Decoding error, image format unsupported” in Microsoft Face API)

我正在尝试使用Microsoft Face API。为此，我将以下代码作为示例提供给Microsoft（在本页末尾https://dev.projectoxford.ai/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395236 ）：

HttpClient httpclient = HttpClients.createDefault(); try { URIBuilder builder = new URIBuilder("https://api.projectoxford.ai/face/v1.0/detect"); builder.setParameter("returnFaceId", "false"); builder.setParameter("returnFaceLandmarks", "false"); builder.setParameter("returnFaceAttributes", "age,gender"); URI uri = builder.build(); HttpPost request = new HttpPost(uri); request.setHeader("Content-Type", "application/octet-stream"); request.setHeader("Ocp-Apim-Subscription-Key", "..."); String body = Base64.encodeBase64String(img); StringEntity reqEntity = new StringEntity(body); request.setEntity(reqEntity); HttpResponse response = httpclient.execute(request); HttpEntity entity = response.getEntity(); if (entity != null) { System.out.println(EntityUtils.toString(entity)); return JsonParser.parse(EntityUtils.toString(entity)); } } catch (URISyntaxException | IOException | ParseException e) { System.out.println(e.getMessage()); } return null;

但是我收到以下错误：

{"error":{"code":"InvalidImage","message":"Decoding error, image format unsupported."}}

我用于测试的图像是这样的： http ： //www.huntresearchgroup.org.uk/images/group/group_photo_2010.jpg （通过快速搜索在互联网上找到它）

它尊重微软设定的所有要求，尺寸和格式......如果我在网站上使用它，它可以运行https://www.projectoxford.ai/demo/face#detection

从我的字节数组转换为base64中的字符串的String body也可以，我在这个网站上测试它： http ： //codebeautify.org/base64-to-image-converter

错误信息很简单，但我看不到我在哪里。任何人都可能知道这个问题是什么？

UPDATE

变量img ：

img = Files.readAllBytes(Paths.get(imgPath));

I'm trying to use Microsoft Face API. For that I have the following code that was given by Microsoft as a sample (at the end of this page https://dev.projectoxford.ai/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395236):

HttpClient httpclient = HttpClients.createDefault(); try { URIBuilder builder = new URIBuilder("https://api.projectoxford.ai/face/v1.0/detect"); builder.setParameter("returnFaceId", "false"); builder.setParameter("returnFaceLandmarks", "false"); builder.setParameter("returnFaceAttributes", "age,gender"); URI uri = builder.build(); HttpPost request = new HttpPost(uri); request.setHeader("Content-Type", "application/octet-stream"); request.setHeader("Ocp-Apim-Subscription-Key", "..."); String body = Base64.encodeBase64String(img); StringEntity reqEntity = new StringEntity(body); request.setEntity(reqEntity); HttpResponse response = httpclient.execute(request); HttpEntity entity = response.getEntity(); if (entity != null) { System.out.println(EntityUtils.toString(entity)); return JsonParser.parse(EntityUtils.toString(entity)); } } catch (URISyntaxException | IOException | ParseException e) { System.out.println(e.getMessage()); } return null;

but I get the following error:

{"error":{"code":"InvalidImage","message":"Decoding error, image format unsupported."}}

The image that I am using for tests is this one: http://www.huntresearchgroup.org.uk/images/group/group_photo_2010.jpg (found it on the internet in a quick search)

It respect all the requisits set by Microsoft, size and format... If I use it in the site it works https://www.projectoxford.ai/demo/face#detection

The String body from the convertion of my array of bytes to a string in base64 is also ok, I test it in this website: http://codebeautify.org/base64-to-image-converter

The error message it's quite simple, but I fail to see where I am worng. Anyone might know whats the problem?

UPDATE

The variable img:

img = Files.readAllBytes(Paths.get(imgPath));
