File 如何创建azure文件存储SAS url(没有azure库)?
我的主要目标是为文件创建一个SAS url(没有azure库)。 我尝试用blob创建azure存储SAS,一切正常。当我尝试在文件中执行相同操作时,我遇到了一个错误。这是我的代码:File 如何创建azure文件存储SAS url(没有azure库)?,file,azure,geturl,File,Azure,Geturl,我的主要目标是为文件创建一个SAS url(没有azure库)。 我尝试用blob创建azure存储SAS,一切正常。当我尝试在文件中执行相同操作时,我遇到了一个错误。这是我的代码: string azAccName = "AccountName"; string resource = "/upgfile/prt.png"; string endPoint = "https://" + azAccName + ".file.core.windows.net"; string uri = endP

我有几乎相同的blob(小差异)代码,它工作正常。
有什么建议吗?我认为问题在于您的
stringToSign
中缺少参数。必须包括指定的所有参数:
如果未使用参数(例如,案例中的signedIP
),则必须指定空行
基于此,您的StringToSign
应该是:
string StringToSign = signedpermissions + "\n" +
signedstart + "\n" +
signedexpiry + "\n" +
canonicalizedresource + "\n" +
signedidentifier + "\n" +
"\n" + //For signed IP
"\n" + //For signed Protocol
signedversion + "\n" +
rscc + "\n" +
rscd + "\n" +
rsce + "\n" +
rscl + "\n" +
rsct;
此外,链接中的sr
(签名资源类型)应该是f
(用于文件),而不是您正在使用的c
string StringToSign = signedpermissions + "\n" +
signedstart + "\n" +
signedexpiry + "\n" +
canonicalizedresource + "\n" +
signedidentifier + "\n" +
"\n" + //For signed IP
"\n" + //For signed Protocol
signedversion + "\n" +
rscc + "\n" +
rscd + "\n" +
rsce + "\n" +
rscl + "\n" +
rsct;
