按官方SDK指引编译运行后报错
CosClientException:
COSXML.CosException.CosClientException:
Error: NameResolutionFailure --->
System.Net.WebException: Error: NameResolutionFailure
调试后发现 cosXml 中的 Appid 为 null
CosXmlConfig config = new CosXmlConfig.Builder()
.SetAppid("appid") //←←← 在config中追加Appid
.SetRegion("COS_REGION")
.Build();
