Ta的回复 ：unity 接入，也需要token？  client = new Ocr(API_KEY, SECRET_KEY); client.Timeout = 60000; var result = client.GeneralBasic(imageTytes); 这样调用，为什么识别不出来文字，异常了System.Net.WebException: Error writing request: The authentication or decryption has failed.

Ta的回复 ：为什么我识别不出来，对版本有什么要求么，  我是用的unity5.6.3 client = new Ocr(API_KEY, SECRET_KEY); client.Timeout = 60000; var result = client.AccurateBasic(imageTytes); var result = client.GeneralBasic(imageTytes); 这2个方法都识别不出来，报了这个异常System.Net.WebException: Error writing request: The authentication or decryption has failed.  能指点一二么

Ta的回复 ：异常：System.Net.WebException: Error writing request: The authentication or decryption has failed. at System.Net.WebConnectionStream.WriteHeaders () [0x00000] in :0 at System.Net.WebConnectionStream.SetHeaders (System.Byte[] buffer) [0x00000] in :0 at (wrapper remoting-invoke-with-check) System.Net.WebConnectionStream:SetHeaders (byte[]) at System.Net.HttpWebRequest.SendRequestHeaders (Boolean propagate_error) [0x00000] in :0

Ta的回复 ：public class Ocr : AipServiceBase { public Ocr(string apiKey, string secretKey); api里只有2个参数的构造函数

Ta的回复 ：异常：System.Net.WebException: Error writing request: The authentication or decryption has failed. at System.Net.WebConnectionStream.WriteHeaders () [0x00000] in :0 at System.Net.WebConnectionStream.SetHeaders (System.Byte[] buffer) [0x00000] in :0 at (wrapper remoting-invoke-with-check) System.Net.WebConnectionStream:SetHeaders (byte[]) at System.Net.HttpWebRequest.SendRequestHeaders (Boolean propagate_error) [0x00000] in :0   这个错误怎么处理

Ta的回复 ：嗯， 去了试了也是一样报错，就几句代码你能试下可以识别么

Ta的回复 ：[图片] 就是取的这2俩个值

Ta的回复 ：如果成功有值，这是返回一个json格式的字符串。 有值是能输出的{"log_id": 8925564128101011311, "words_result_num": 1, "words_result": [{"location": {"width": 89, "top": 0, "left": 84, "height": 47}, "words": "2020"}]

Ta的回复 ：感谢，用post请求可以识别了，我以为sdk直接封装好了，看来还是得自己去请求

Ta的回复 ：好的，感谢

Ta的回复 ：unity3d,摄像头抓取画面，一秒钟调用一次图片识别接口Ocr client.GeneralBasic()，检测图片中的文字，画面出现明显卡帧现象，不调用就很流畅。
