问题描述
我正在尝试访问位于SharePoint站点上的Excel文件。我没有从服务器端进行修改的选择。我可以从chrome访问文件，当我输入链接时，文件会自动下载。但是，当我尝试使用C＃代码（.Net框架4.6.1）下载时，出现了未经授权的异常，401错误代码。 我尝试了几件事。 首先，我尝试了CSOM（客户端共享点对象模型）。代码如下

我对sharepoint还是陌生的，我感谢任何帮助。提前致谢。 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ 再次试用
static void Main(string[] args)
{
var link = @"sitelink";
var link2 = @"filelink";
var credential = new CredentialCache
{
{ new Uri(link2),"NTLM",CredentialCache.DefaultNetworkCredentials}
};
var options = new httpclienthandler
{
Credentials = credential
};
//var client = new HttpClient(options);
using (var client = new HttpClient(options))
{
var requestMessage = new HttpRequestMessage();
requestMessage.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED","f");
requestMessage.Method = HttpMethod.Get;
requestMessage.RequestUri = new Uri(link2);
requestMessage.Headers.Add("Use-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/84.0.4147.135 Safari/537.36");
var response = client.SendAsync(requestMessage).Result;
Console.WriteLine(JsonConvert.SerializeObject(response,Formatting.Indented));
if (response != null && response.IsSuccessstatusCode)// <- Status false,Unautherized is in the response header
{
using (var reader = new io.StreamReader(response.Content.ReadAsstreamAsync().Result))
{
io.File.WriteallText(@"C:\Users\Name\source\repos\TestExcel.xlsx",reader.ReadToEndAsync().Result );
}
}
}
Console.WriteLine("DOne");
}
完成序列化异常对象
var link2 = @"file link";
var client = new HttpClient(new httpclienthandler
{
UseDefaultCredentials = true
});
io.Stream resultStream = null;
try
{
resultStream = client.GetStreamAsync(link2).Result;
var reader = new io.StreamReader(resultStream);
io.File.WriteallText(@"C:\Users\Name\source\repos\TestExcel.xlsx",reader.ReadToEndAsync().Result);
reader.Close();
} catch (Exception e)
{
Console.WriteLine(JsonConvert.SerializeObject(e,Formatting.Indented));
}
Console.WriteLine("Done");
Console.ReadLine();
更新 Sharepoint托管在Office 365中。 看来Office 365正在处理授权。当我使用chrome dev工具进行检查时，在源文件中找到了两个js文件（我在这里不能提及的名称）。
