Question

我正在尝试使用RSS feed URL生成XML格式的数据。我有一个例外：

远程服务器返回错误（400）错误的请求错误。

我正在使用SSIS包，并在控制流中创建了一个安全任务，我编写的脚本如下：

public bool DownloadFeed()
{
    string user = "xxx";
    string password = "pwd";

    WebClient web = new WebClient();
    System.Net.WebClient wc = new System.Net.WebClient();
    wc.Credentials = new System.Net.NetworkCredential(user, password);
    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3 | 
                                                        SecurityProtocolType.Tls | 
                                                        SecurityProtocolType.Tls11 | 
                                                        SecurityProtocolType.Tls12;
    wc.DownloadFile(@"https://Entered RSS Feed URL here", @"H:\import\Test.xml");
    return true;
}

这可能是格式化凭证并将其传递到服务器的方式。你可以试试吗？

using System.Net;

public bool DownloadFeed()
{
    string user = "xxx";
    string password = "pwd";

    System.Net.WebClient wc = new System.Net.WebClient();
    string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(user + ":" + password));
    wc.Headers[HttpRequestHeader.Authorization] = "Basic " + credentials;
    System.Net.ServicePointManager.SecurityProtocol =      System.Net.SecurityProtocolType.Ssl3 | 
                                                    SecurityProtocolType.Tls | 
                                                    SecurityProtocolType.Tls11 | 
                                                    SecurityProtocolType.Tls12;
    wc.DownloadFile(@"https://Entered RSS Feed URL here", @"H:\import\Test.xml");
    return true;
}
