使用Unity开发，调人体分析--手势识别的api，提示

WebException: Error writing request: The authentication or decryption has failed.
System.Net.WebConnectionStream.WriteHeaders ()
System.Net.WebConnectionStream.SetHeaders (System.Byte[] buffer)
(wrapper remoting-invoke-with-check) System.Net.WebConnectionStream:SetHeaders (byte[])
System.Net.HttpWebRequest.SendRequestHeaders (Boolean propagate_error)

各位遇到过么。

在start里调下面方法就会报错。

public void GestureDemo() {
     var APP_ID = "XXXX";
     var API_KEY = "XXXXXXXXX";
     var SECRET_KEY = "XXXXXXXXXXXXXX";
     var client = new Baidu.Aip.BodyAnalysis.Body(API_KEY, SECRET_KEY);
     client.Timeout = 60000; // 修改超时时间

     var image = File.ReadAllBytes(Application.streamingAssetsPath+"/h3.jpg");
     JObject result = client.Gesture(image);
     Debug.Log (result);
}
