我有一个用 C# 编写的应用程序，因此它可以是一个独立的 .exe，并在运行时通过 cmd 传入参数。我正在尝试更新 google 驱动器中的文件而不更改 fileid，以便使用该 id 的任何链接都不会被破坏。以下代码一直有效，直到使用 Google.Apis.Drive.v3.Data.File updateFile 到达第三部分，其中文件始终为“null”。 request.ResponseBody 具有正确的 fileId、正确的路径，并且几乎总是出现空值。
我怎样才能得到它来更新文件？
是否有一些代码更新/更改不再有效？
任何帮助，将不胜感激-

第 2 部分 - 这是更新文件列表中的文件的代码的中间部分，该列表调用每个文件来更新它。
public static String GDrive_Update_File(string pathToFile, string localFilePath, string fileName, string description, string parentFolder = "", string userid = "", string sharedUserIds = "", string sharerole = "", string teamID = "", string parentFolderID = "")
{
FileResponseJSON fileJson = new FileResponseJSON();
List<string> fileArray = new List<string> { };
IList<FileResponseJSON> filesJSON = new List<FileResponseJSON>();
IList<Google.Apis.Drive.v3.Data.File> files = new List<Google.Apis.Drive.v3.Data.File>();
List<string> parents = new List<String> { };
List<string> kids = new List<String> { };
UserCredential credential = GoogleAPI_Functions.GetCredentials(userid);
var service = new DriveService(new BaseClientService.Initializer
{
ApplicationName = APP_NAME,
HttpClientInitializer = credential,
});
if (!String.IsNullOrEmpty(parentFolder))
{
FilesResource.ListRequest listRequest = service.Files.List();
listRequest.Q = String.Format("(name contains '{0}') and (mimeType = 'application/vnd.google-apps.folder')", parentFolder);
listRequest.Fields = "files(*)";
if (teamID.Length > 3)
{
listRequest.SupportsTeamDrives = true; // new
listRequest.Corpora = "teamDrive"; // new
listRequest.IncludeTeamDriveItems = true;//new
listRequest.TeamDriveId = teamID;//new
}
// List files.
IList<Google.Apis.Drive.v3.Data.File> folders = listRequest.Execute().Files;
foreach (var fldr in folders)
{
if (parentFolderID.Length > 3)
{
if (fldr.Id.Equals(parentFolderID))
{
parents.Add(fldr.Id);
}
}
else
{
parents.Add(fldr.Id);
}
Console.WriteLine("value of fldr.Id " + fldr.Id);
}
}
// Upload File MetaData
// mimeType is important and so it the 'trashed' true/false or it won't be found
FilesResource.ListRequest fileRequest = service.Files.List();
string query = "name contains 'update_file.txt' and (mimeType = 'text/plain') and trashed = false";
fileRequest.Q = String.Format(query);
fileRequest.Fields = "files(*)";
fileRequest.SupportsTeamDrives = true; // new
fileRequest.Corpora = "teamDrive"; // new
fileRequest.IncludeTeamDriveItems = true;//new
fileRequest.TeamDriveId = teamID;//new
IList<Google.Apis.Drive.v3.Data.File> myFiles = fileRequest.Execute().Files;
Console.WriteLine("Files:");
if (myFiles != null && myFiles.Count > 0)
{
foreach (var myf in myFiles)
{
myf.Name = localFilePath + myf.Name;
Console.WriteLine("{0} ({1})", myf.Name, myf.Id);
UpdateFile(service, myf.Name, myf.Id);
}
}
else
{
Console.WriteLine("No files found.");
}
Console.Read();
var UpdatedID = "";
return UpdatedID;
}
第 3 节 - 本节应该更新每个文件 --> 这是有问题的部分（Google.Apis.Drive.v3.Data.File UpdatedFile 始终返回 null）
public static Google.Apis.Drive.v3.Data.File UpdateFile(DriveService _service, string _uploadFile, string _fileId)
{
Google.Apis.Drive.v3.Data.File file = new Google.Apis.Drive.v3.Data.File();
byte[] byteArray = System.IO.File.ReadAllBytes(_uploadFile);
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
FilesResource.UpdateMediaUpload request = _service.Files.Update(file, _fileId, stream, GetMimeType(_uploadFile));
void Upload_ProgressChanged(IUploadProgress progress) =>
Console.WriteLine(progress.Status + " " + progress.BytesSent);
void Upload_ResponseReceived(Google.Apis.Drive.v3.Data.File myfile) =>
Console.WriteLine(myfile.Name + " was uploaded successfully");
request.ProgressChanged += Upload_ProgressChanged;
request.ResponseReceived += Upload_ResponseReceived;
request.Upload();
Google.Apis.Drive.v3.Data.File updatedFile = request.ResponseBody;
return updatedFile;
}
更新：我使用 IUploadProgress.Exception 并收到以下错误 -
Exception: The service drive has thrown an exception: Google.GoogleApiException: Google.Apis.Requests.RequestError
File not found: 1XYZ..... [404]
Errors [
Message[File not found: 1XYZ.......] Location[fileId - parameter] Reason[notFound] Domain[global]

再次更新，我能够看到正在生成的 uri 并将其复制/粘贴到浏览器中，当我这样做时，我得到了 405 Method Not allowed;另外，当我尝试不使用 https 并仅使用 http 时，我得到了 403 Forbidden，并且需要 SSL 才能执行此操作
这是没有 ids 的 uri
更新：
在此过程中，api 会生成这两个 url，它们都可以工作并允许我访问
网页内容链接
"https://drive.google.com/uc?id=[docID]&export=download"
网页浏览链接
"https://drive.google.com/file/d/[docID]/view?usp=drivesdk"
最新更新应用了 DalmTo 的修复，但收到新错误 -
// - removed // Google.Apis.Drive.v3.Data.File file = new
// - added //
var fileMetadata = new Google.Apis.Drive.v3.Data.File()
{
Id = _fileId
};
var fsSource = new MemoryStream(Encoding.UTF8.GetBytes(_uploadFile ?? ""));
var request = _service.Files.Update(fileMetadata, fileMetadata.Id, fsSource, GetMimeType(_uploadFile));
新错误：
Exception: The service drive has thrown an exception: Google.GoogleApiException: Google.Apis.Requests.RequestError
The resource body includes fields which are not directly writable. [403]
Errors [
Message[The resource body includes fields which are not directly writable.] Location[ - ] Reason[fieldNotWritable] Domain[global]
]
不知道什么会导致这种情况。
