我创建了一个SSIS包,它使用C#脚本从HTTPS URL下载CSV文件。从Visual Studio执行时一切正常。
但是,当我建立SQL Agent作业时,封装会失败。如果我直接从SQL Server执行.dtsx档案,封装也会失败。
错误为
“下载失败:从服务器获取的SSL证书响应无效。无法处理请求”
我已测试从SQL服务器打开URL,并可以查看文件。我还在C#脚本中添加了代码以忽略证书错误,但这似乎没有任何影响。我还在连接管理器中输入了托管CSV的服务器的登录凭据,但这也没有帮助。
CSV是通过Magento数据源生成的。在网站上,所有内容都被重定向到HTTPS。
我在这里迷路了,所以希望有人能好心地帮助我。
下面是C#脚本的片段:
public void Main()
{
// TODO: Add your code here
try
{
// Ignore certificate warnings
ServicePointManager.ServerCertificateValidationCallback =
new RemoteCertificateValidationCallback(delegate { return true; });
// Disable server certificate validation.
//ServicePointManager
// .ServerCertificateValidationCallback +=
// (sender, cert, chain, sslPolicyErrors) => true;
//ServicePointManager.ServerCertificateValidationCallback = (sender, cert, chain, sslPolicyErrors) => true;
//System.Net.ServicePointManager.ServerCertificateValidationCallback =
//delegate (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
//{ return true; };
// Logging start of download
bool fireAgain = true;
Dts.Events.FireInformation(0, "Download File", "Start downloading " + Dts.Connections["TEST"].ConnectionString, string.Empty, 0, ref fireAgain);
// Get your newly added HTTP Connection Manager
Object mySSISConnection = Dts.Connections["TEST"].AcquireConnection(null);
// Create a new connection
HttpClientConnection myConnection = new HttpClientConnection(mySSISConnection);
// Download file and use the Flat File Connectionstring (D:\SourceFiles\Products.csv)
// to save the file (and replace the existing file)
String filename = Dts.Variables["varFullPathScript"].Value.ToString();
myConnection.DownloadFile(filename, true);
// Logging end of download
Dts.Events.FireInformation(0, "Download File", "Finished downloading" , string.Empty, 0, ref fireAgain);
// Quit Script Task succesful
Dts.TaskResult = (int)ScriptResults.Success;
}
catch (Exception ex)
{
// Logging why download failed
Dts.Events.FireError(0, "Download File", "Download failed: " + ex.Message, string.Empty, 0);
// Quit Script Task unsuccesful
Dts.TaskResult = (int)ScriptResults.Failure;
}
Dts.TaskResult = (int)ScriptResults.Success;
}

经过一番努力,我想我应该尝试一些简单的方法,即使用不同的方法来下载文件。我使用了一个webclient类,而不是HTTP连接管理器。这似乎已经工作!

@乔纳森C -首先,谢谢你的想法,我也有同样的问题,你救了我的一天,但是
System.Net.ServicePointManager.SecurityProtocol=System.Net.SecurityProtocolType.Tls12;
之前添加此字符串之前,在发送” 异常时发生意外错误1.在这种情况下,我建议使用
using
关键字所以在我的案例中,最后的结果是
