问题描述
string remoteUri = "http://www.contoso.com/library/homepage/images/";
string fileName = "ms-banner.gif", myStringWebResource = null;
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Concatenate the domain with the Web resource filename.
myStringWebResource = remoteUri + fileName;
Console.WriteLine("Downloading File \"{0}\" from \"{1}\" .......\n\n", fileName, myStringWebResource);
// Download the Web resource and save it into the current filesystem folder.
myWebClient.DownloadFile(myStringWebResource,fileName);
Console.WriteLine("Successfully Downloaded File \"{0}\" from \"{1}\"", fileName, myStringWebResource);
Console.WriteLine("\nDownloaded file saved in the following file system folder:\n\t" + Application.StartupPath);
我正在使用 MSDN中的代码网站
但是我遇到了错误:禁止403
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,它仍然继续显示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.因此,完整的代码如下所示:
After this it started working. So the full code goes like below:
const string username = "[email protected]";
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);
}
}
