我过去几天一直试图将文件放入我的应用程序中的samba共享文件夹中。
到目前为止故事
我获取了UNCAccessWithCredentials找到的here类的副本，并在我的存储库中引用了它。该课程使用NetApi32.dll
我编写了以下代码来检查是否存在连接，如果没有，则创建连接。
bool available = UNCConnection.IsNetworkPathAvailable(WebConfigurationManager.AppSettings[@"ExportFilePath"]);
string uncpath = WebConfigurationManager.AppSettings[@"ExportFilePath"];
string user = WebConfigurationManager.AppSettings["ExportUser"];
string password = WebConfigurationManager.AppSettings["ExportPassword"];
string domain = @"";
string filePath = uncpath + @"\exportFile" + ".txt";
if (!available)
{
using (UNCAccessWithCredentials unc = new UNCAccessWithCredentials())
{
var x = unc.NetUseWithCredentials(uncpath, user, domain, password);
if (x)
{
CsvContext cc = new CsvContext();
cc.Write(
chargesForExport,
filePath,
outputFileDescription);
}
else
{
var error = unc.GetStatusCodeDefinition(unc.LastError);
throw new Exception(String.Format("The following error occured whilst writing to the creditors folder: {0}", error));
}
}
}
else
{
CsvContext cc = new CsvContext();
cc.Write(
chargesForExport,
filePath,
outputFileDescription);
}
问题
通过IIS Express在调试中运行时，这没有问题。
我从cmd行运行'net use'并在unc.NetUseWithCredentials
之前 - 没有连接
在 - 连接期间
使用后 - 无连接
当我在完全成熟的IIS上部署到实时或本地托管时，我看到错误代码'1326'，我相信这意味着ERROR_LOGON_FAILURE。这些凭据肯定有效，因为我可以使用它们浏览到该文件夹，我可以使用它们将网络驱动器映射到此文件夹，它们与我在调试时使用的凭据相同。
我尝试了什么
我已尝试映射网络共享，使用netuse / delete关闭所有现有连接，将IIS应用程序池中的标识更改为自定义帐户，管理员或我的个人AD帐户都没有区别。我还运行了caspol将策略设置为完全信任，但我仍然看到错误 1326 。
我不明白为什么在运行IIS Express时这种方法运行得很好，但是当我在完整的IIS上托管它时，我只看到错误 1326 。
有人能在这看到问题吗？？
