            // Create a new WebClient instance.

我正在使用 MSDN 中的代码网站

但是我遇到了错误:403 forbidden

But I have coming across the error: 403 forbidden

有人可以帮我解决这个问题吗?

Can someone Help me Put this working ?

推荐答案

我遇到了同样的问题并尝试了 Vadim Gremyachev 建议的答案.但是，它仍然不断给出 403 错误.我添加了两个额外的标头来强制基于表单的身份验证，如下所示:

I was facing the same issue and tried the answer suggested by Vadim Gremyachev. However, it still kept giving 403 error. I added two extra headers to force form based authentication like below:

client.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
client.Headers.Add("User-Agent: Other");

此后它开始工作.所以完整的代码如下:

After this it started working. So the full code goes like below:

const string username = "[e-mail]";
const string password = "password";
const string url = "https://tenant.sharepoint.com/";
var securedPassword = new SecureString();
foreach (var c in password.ToCharArray()) securedPassword.AppendChar(c);
var credentials = new SharePointOnlineCredentials(username, securedPassword);

DownloadFile(url,credentials,"/Shared Documents/Report.xslx");


private static void DownloadFile(string webUrl, ICredentials credentials, string fileRelativeUrl)
{
     using(var client = new WebClient())
     {
        client.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
        client.Headers.Add("User-Agent: Other");
        client.Credentials = credentials;
        client.DownloadFile(webUrl, fileRelativeUrl);
     }  
}
