我需要上传我的谷歌驱动器上的文件(pdf,word,excel),如何在ASP.NET中使用C#做到这一点?你能否一步一步解释我所有的经文?如果它是有用的,我把我最后的测试代码:上传文件到Google Drive
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.UI;
using System.Web.UI.WebControls;
using ASPSnippets.GoogleAPI;
using System.Runtime.Serialization;
using System.IO;
using System.Web.Script.Serialization;
...
protected void Page_Load(object sender, EventArgs e)
{
GoogleConnect.ClientId = "my_client_id";
GoogleConnect.ClientSecret = "my_client_secret";
GoogleConnect.RedirectUri = Request.Url.AbsoluteUri.Split('?')[0];
GoogleConnect.API = EnumAPI.Drive;
if (!string.IsNullOrEmpty(Request.QueryString["code"]))
{
string code = Request.QueryString["code"];
string json = GoogleConnect.PostFile(code, (HttpPostedFile)Session["File"], Session["Description"].ToString());
GoogleDriveFile file = (new JavaScriptSerializer()).Deserialize<GoogleDriveFile>(json);
tblFileDetails.Visible = true;
lblTitle.Text = file.Title;
lblId.Text = file.Id;
imgIcon.ImageUrl = file.IconLink;
lblCreatedDate.Text = file.CreatedDate.ToString();
lnkDownload.NavigateUrl = file.WebContentLink;
if (!string.IsNullOrEmpty(file.ThumbnailLink))
{
rowThumbnail.Visible = true;
imgThumbnail.ImageUrl = file.ThumbnailLink;
}
}
if (Request.QueryString["error"] == "access_denied")
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", "alert('Access denied.')", true);
}
}
protected void UploadFile(object sender, EventArgs e)
{
Session["File"] = FileUpload1.PostedFile;
Session["Description"] = txtDescription.Text;
GoogleConnect.Authorize("https://www.googleapis.com/auth/drive.file");
}
}
public class GoogleDriveFile
{
public string Id { get; set; }
public string Title { get; set; }
public string OriginalFilename { get; set; }
public string ThumbnailLink { get; set; }
public string IconLink { get; set; }
public string WebContentLink { get; set; }
public DateTime CreatedDate { get; set; }
public DateTime ModifiedDate { get; set; }
}
但我有此错误:
- That’s an error.
Error: redirect_uri_mismatch

我已经插入重定向页面,但它给了我同样的错误。
当您向OAuth网站注册时,一旦该应用程序获得授权,您就可以告知其将用户重定向到哪个网页。错误消息说''http:// localhost:61360/Prova.aspx''不是你注册的那个。您在Google应用中注册的网址是什么? – Neil
我不插入任何重定向页面...我只创建了一个应用程序,并在程序中使用了id和秘密。我应该把什么作为重定向网址? –
也许我可以更好地解释:在“console.developers.google.com”,“凭据”中,我创建的“ID客户端OAuth 2.0”中,我只提供了名称字段。在“共识产品屏幕”中,我只有我的电子邮件地址和产品名称 –
