我正在尝试通过SFTP
程序包连接到SSIS
服务器。程序包使用WinSCP
文件中的以下连接字符串执行.txt
:
open sftp://username:fc$#[email protected]:22
但是,该软件包一直无法连接而失败。与密码中的特殊字符有关吗?
如果替换字符串,我能够连接到其他SFTP,所以我知道这一定与上面的语法有关。我尝试如下将双引号引起来,但没有成功:
open "sftp://username:fc$#[email protected]:22"
最近我的一个工作项目我也必须这样做。我们在SSIS脚本任务中使用了WinSCP .NET程序集,因为WinSCP也建议将其作为在SSIS中使用WinSCP来实现SFTP的方法。
请参见本指南-Using WinSCP .NET Assembly from SQL Server Integration Services (SSIS)。它会引导您完成安装和设置,并包含有效的示例代码(当然,在您根据需要更改脚本之后!)。
示例代码-在引用WinSCPnet.dll
程序集后-在下面。
using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.ScriptTask;
using System.AddIn;
using WinSCP;
namespace ST_5a30686e70c04c5a8a93729fd90b8c79.csproj
{
[AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
public partial class ScriptMain : VSTARTScriptObjectModelBase
{
public void Main()
{
// Setup session options
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Sftp,
// To setup these variables, go to SSIS > Variables.
// To make them accessible from the script task, in the context menu of the task,
// choose Edit. On the Script task editor on Script page, select ReadOnlyVariables,
// and tick the below properties.
HostName = (string) Dts.Variables["User::HostName"].Value,
UserName = (string) Dts.Variables["User::UserName"].Value,
Password = (string) Dts.Variables["User::Password"].Value,
SshHostKeyFingerprint = (string) Dts.Variables["User::SshHostKeyFingerprint"].Value
};
try
{
using (Session session = new Session())
{
// As WinSCP .NET assembly has to be stored in GAC to be used with SSIS,
// you need to set path to WinSCP.exe explicitly, if using non-default location.
session.ExecutablePath = @"C:\winscp\winscp.exe";
// Connect
session.Open(sessionOptions);
// Upload files
TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;
TransferOperationResult transferResult;
transferResult = session.PutFiles(@"d:\toupload\*", "/home/user/", false, transferOptions);
// Throw on any error
transferResult.Check();
// Print results
bool fireAgain = false;
foreach (TransferEventArgs transfer in transferResult.Transfers)
{
Dts.Events.FireInformation(0, null,
string.Format("Upload of {0} succeeded", transfer.FileName),
null, 0, ref fireAgain);
}
}
Dts.TaskResult = (int)DTSExecResult.Success;
}
catch (Exception e)
{
Dts.Events.FireError(0, null,
string.Format("Error when using WinSCP to upload files: {0}", e),
null, 0);
Dts.TaskResult = (int)DTSExecResult.Failure;
}
}
}
