[英]Issue with azure cognitive translation services
在使以下代碼可靠運行一個月左右后,幾天前它停止了可靠運行。 它大約有一半的時間返回正確翻譯的字符串,而另一半則返回以下兩個消息之一:
java.io.FileNotFoundException: https : //api.cognitive.microsoft.com/sts/v1.0/issueToken
java.net.UnknownHostException:無法解析主機“ api.microsofttranslator.com”:沒有與主機名關聯的地址
這個問題開始的時間恰好是我的免費Azure認知服務帳戶到期的時間,但是我昨天遷移到了“現收現付”帳戶,問題仍然存在。
為什么會這樣呢?
