本人现在需要做一个项目（网络学习平台），项目中会用到一些资源文件（学习课件），本人想把这些资源放在百度云盘上，在程序中通过百度云盘的分享地址实现自动下载。请高手职教。 解决方案 10 可以调用百度云的Api，看这里 20 错误码是什么，可以对照这个 引用: 本人只是需要通过百度云盘分享出来的网址来下载文件，然后总是报403错误。是必须要申请API Key（client_id）与Secret Key（client_secret）和access Token吗？ public class BaiDuYunDownLoad { public static void DownLoad(string url, string saveFilePath) { try { HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url); request.Referer = url; request.Method = "GET"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 2.0.1124)"; request.ContentType = "application/octet-stream"; request.Accept = "image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*"; request.Timeout = 20*1000; request.AllowAutoRedirect = true; //request.ClientCertificates.Add(new X509Certificate2(cert_path,cert_password)); HttpWebResponse response = (HttpWebResponse) request.GetResponse(); Stream responseStream = response.GetResponseStream(); if (response.StatusCode == HttpStatusCode.OK) { FileStream fileStream = new FileStream(saveFilePath, FileMode.Create, FileAccess.ReadWrite); if (responseStream != null) { responseStream.Flush(); StreamReader sr = new StreamReader(responseStream); string buffer = sr.ReadToEnd(); byte[] bt = new UTF8Encoding(true).GetBytes(buffer); fileStream.Write(bt, 0, bt.Length); } fileStream.Close(); } else { throw new Exception("服务器返回状态失败,StatusCode:" + response.StatusCode); } } catch (Exception e) { Console.WriteLine(e.Message); throw new Exception("无法连接下载地址"); } } } 10 引用: 本人只是需要通过百度云盘分享出来的网址来下载文件，然后总是报403错误。是必须要申请API Key（client_id）与Secret Key（client_secret）和access Token吗？ public class BaiDuYunDownLoad { public static void DownLoad(string url, string saveFilePath) { try { HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url); request.Referer = url; request.Method = "GET"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 2.0.1124)"; request.ContentType = "application/octet-stream"; request.Accept = "image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*"; request.Timeout = 20*1000; request.AllowAutoRedirect = true; //request.ClientCertificates.Add(new X509Certificate2(cert_path,cert_password)); HttpWebResponse response = (HttpWebResponse) request.GetResponse(); Stream responseStream = response.GetResponseStream(); if (response.StatusCode == HttpStatusCode.OK) { FileStream fileStream = new FileStream(saveFilePath, FileMode.Create, FileAccess.ReadWrite); if (responseStream != null) { responseStream.Flush(); StreamReader sr = new StreamReader(responseStream); string buffer = sr.ReadToEnd(); byte[] bt = new UTF8Encoding(true).GetBytes(buffer); fileStream.Write(bt, 0, bt.Length); } fileStream.Close(); } else { throw new Exception("服务器返回状态失败,StatusCode:" + response.StatusCode); } } catch (Exception e) { Console.WriteLine(e.Message); throw new Exception("无法连接下载地址"); } } } 你需要在百度上申请一下开发者账号，然后按照一楼的操作来做 CodeBye 版权所有丨如未注明 , 均为原创丨本网站采用BY-NC-SA协议进行授权 , 转载请注明c# winform程序怎么样通过百度云盘下载文件！ 喜欢 (0)赏[1034331897@qq.com]分享 (0)
