Question

我正在尝试使用Microsoft Azure认知服务面部检测。我做错了。我正在尝试使用C＃SDK进行面部检测。我收到下面的错误。我不知道该如何调试此错误消息或告诉我什么。几乎就像我设置的东西一样，但我只是在猜测。

 Microsoft.Azure.CognitiveServices.Vision.Face.Models.APIErrorException
  HResult=0x80131500
  Message=Operation returned an invalid status code 'BadRequest'
  Source=Microsoft.Azure.CognitiveServices.Vision.Face
  StackTrace:

我拨打电话的代码是：

    string faceEndpoint = "https://eastus.api.cognitive.microsoft.com";
    FaceAttributeType[] faceAttributes =
    { FaceAttributeType.Age, FaceAttributeType.Gender, FaceAttributeType.Hair, 
        FaceAttributeType.Smile, FaceAttributeType.Gender, FaceAttributeType.Emotion, FaceAttributeType.FacialHair, 
        FaceAttributeType.Accessories  };
    FaceClient faceClient = new FaceClient( new ApiKeyServiceClientCredentials(connString), new System.Net.Http.DelegatingHandler[] { });
    faceClient.Endpoint = faceEndpoint;
    var ctx = new BWDContext();
    var pics = await (from p in ctx.Picture where p.DateOfFacial == null select p).ToListAsync();
    foreach(var pic in pics)
    {
        if(Uri.IsWellFormedUriString(pic.PicFileUrl, UriKind.Absolute))
        {
            IList<DetectedFace> faceList =
                await faceClient.Face.DetectWithUrlAsync(pic.PicFileUrl, true, true, faceAttributes); // error occurs here
 .....on and on .......

我还尝试了与提琴手打个电话，这确实有效。在提琴手的电话上，我只是在以下网址上发布了一个帖子：https://eastus.api.cognitive.microsoft.com/face/v1.0/detect?returnFaceId=true&returnFaceLandmarks=false&returnFaceAttributes=age,gender,headPose,smile,facialHair,glasses,emotion,hair,makeup,occlusion,accessories,blur,exposure,noise

我的标题是：

User-Agent: Fiddler
Ocp-Apim-Subscription-Key: ....subscription key......
Content-Type: application/json
Host: eastus.api.cognitive.microsoft.com

我的帖子正文为： {'url'：'https://bwdpictures.blob.core.windows.net/bwdpictures/d916acdd-ab9f-429e-8b75-6d5f9206a9b4.jpg'}

我从提琴手的其余电话中得到了结果。

我确定问题出在我的代码中，但我不知道问题是什么。如果您有任何建议，我将不胜感激。

TIA，沃利

宾果。问题是我在face属性中两次拥有了Gender属性。我只是注意到了。当我拿出第二个时，问题解决了。抱歉，该帖子。
