使用C#下载带密码和用户名的文件

Question

如何编写脚本以从此站点下载文件.是否可以通过URL提供登录名和密码？

http://feeds.itunes.apple.com/feeds/epf/

我会像这样格式化网址吗？

WebClient Client = new WebClient();
Client.DownloadFile("http://feeds.itunes.apple.com/feeds/epf/v3/full/current/itunes20110511.tbz.md5?username=myusername&password=mypassword", @"C:\folder\file.md5");

Answer 1

是的,只需使用用户名/密码将WebClient's Credentials属性设置为NetworkCredentials实例即可.例如:

Client.Credentials = new System.Net.NetworkCredential("john", "password1234!");

Answer 2

使用WebClient.Credentials属性为网站提供凭据:

using (WebClient client = new WebClient()) {
    client.Credentials = new NetworkCredential(username, password);
    client.DownloadFile("http://feeds.itunes.apple.com/feeds/epf/v3/full/current/itunes20110511.tbz.md5", @"C:\folder\file.md5");
}
