401 System.UnauthorizedAccessException 使用 SharpBox 访问 Dropbox 时 API
401 System.UnauthorizedAccessException when access Dropbox With SharpBox API
代码
config = CloudStorage.GetCloudConfigurationEasy(nSupportedCloudConfigurations.DropBox)
as DropBoxConfiguration;
//config.AuthorizationCallBack = new Uri("http://localhost:61926/DBoxDemo.aspx");
requestToken = DropBoxStorageProviderTools.GetDropBoxRequestToken(config, "KEY", "SECRET");
//Session["requestToken"] = requestToken;
string AuthoriationUrl = DropBoxStorageProviderTools.GetDropBoxAuthorizationUrl(
config, requestToken);
Process.Start(AuthoriationUrl);
accessToken = DropBoxStorageProviderTools.ExchangeDropBoxRequestTokenIntoAccessToken(
config, "xxxxxxxxxxxxx", "xxxxxxxxxxxxx", requestToken);
CloudStorage dropBoxStorage = new CloudStorage();
var storageToken = dropBoxStorage.Open(config, accessToken);
var publicFolder = dropBoxStorage.GetFolder("/");
// upload a testfile from temp directory into public folder of DropBox
String srcFile = Environment.ExpandEnvironmentVariables(@"C:\Test\MyTestFile.txt");
var rep = dropBoxStorage.UploadFile(srcFile, publicFolder);
MessageBox.Show("Uploaded Successfully..");
**dropBoxStorage.DownloadFile("/MyTestFile.txt",
Environment.ExpandEnvironmentVariables("D:\test"));**
MessageBox.Show("Downloaded Successfully..");
dropBoxStorage.Close();
这是 Visual Studio 中显示的错误。
SharpBox 有一个只出现在 .NET 4.5 中的错误,因为 class System.Uri
的行为已从 4.0 更改为 4.5。
DropBoxStorageProviderService.cs 中的方法 GetDownloadFileUrlInternal()
生成了不正确的 URL,因为它更改了 %2f 中的斜线。在 .NET 4.0 中,这个 URL 将通过 OAuthUrlGenerator.cs 中方法 GenerateSignedUrl()
中的 System.Uri
对象正确转换回来。 =17=]
我已经从这个改变了方法GetDownloadFileUrlInternal()
...
public static String GetDownloadFileUrlInternal(IStorageProviderSession session, ICloudFileSystemEntry entry)
{
// cast varibales
DropBoxStorageProviderSession dropBoxSession = session as DropBoxStorageProviderSession;
// gather information
String rootToken = GetRootToken(dropBoxSession);
String dropboxPath = GenericHelper.GetResourcePath(entry);
// add all information to url;
String url = GetUrlString(DropBoxUploadDownloadFile, session.ServiceConfiguration) + "/" + rootToken;
if (dropboxPath.Length > 0 && dropboxPath[0] != '/')
url += "/";
url += HttpUtilityEx.UrlEncodeUTF8(dropboxPath);
return url;
}
...到此...
public static String GetDownloadFileUrlInternal(IStorageProviderSession session, ICloudFileSystemEntry entry)
{
// cast varibales
DropBoxStorageProviderSession dropBoxSession = session as DropBoxStorageProviderSession;
// gather information
String rootToken = GetRootToken(dropBoxSession);
// add all information to url;
String url = GetUrlString(DropBoxUploadDownloadFile, session.ServiceConfiguration) + "/" + rootToken;
ICloudFileSystemEntry parent = entry.Parent;
String dropboxPath = HttpUtilityEx.UrlEncodeUTF8(entry.Name);
while(parent != null)
{
dropboxPath = HttpUtilityEx.UrlEncodeUTF8(parent.Name) + "/" + dropboxPath;
parent = parent.Parent;
}
if (dropboxPath.Length > 0 && dropboxPath[0] != '/')
url += "/";
url += dropboxPath;
return url;
}
目前它适用于 .NET 4.5。可能存在解决问题的更好方法,但目前未发现任何不当行为。
