无法下载Office 365 SharePoint库项目

Question

我正在尝试下载Office 365 SharePoint库中存在的项目,WebcClient.DownloadFile()但我收到此异常:

例外:

The remote server returned an error: (403) Forbidden.

示例代码:

NetworkCredential credential = new NetworkCredential("username", "password", "aaa.onmicrosoft.com");
WebClient webClient = new WebClient();
webClient.Credentials = credential;
webClient.DownloadFile(@"https://aaa.sharepoint.com/testDoc/test.pdf", @"c:/test.pdf");

Answer 1

另一种选择是利用SharePointOnlineCredentials类从 SharePoint Online的客户端组件SDK.

SharePointOnlineCredentials类表示提供访问SharePoint Online资源的凭据的对象

先决条件

SharePoint Online Client组件SDK

如何从SharePoint Online下载文件

 public static void DownloadFile(string userName, string password, string fileUrl, string filePath)
 {
        var securePassword = new SecureString();
        foreach (var c in password)
        {
            securePassword.AppendChar(c);
        }
        using (var client = new WebClient())
        {
            client.Credentials = new SharePointOnlineCredentials(userName, securePassword);
            client.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
            client.DownloadFile(fileUrl, filePath);
        }
}
