Python：使用Pydrive库将我自己的文件上传到我的驱动器中

Question

我正在使用Python发现PyDrive API。 我想上传我的文件到我的驱动器。不过，在Pydrive文档中，我只找到upload（）函数，该函数上载由drive.CreateFile（）函数创建并更新的文件，而不是硬盘中的文件（我自己的文件）。

file1 = drive.CreateFile({'title': 'Hello.txt'})  # Create GoogleDriveFile 
instance with title 'Hello.txt'.
file1.SetContentString('Hello World!') # Set content of the file from given 
string.
file1.Upload()

我已经在stackoverflow中尝试了我的问题的答案，但是一个错误被指控了。这是我的代码：

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

#1st authentification
gauth = GoogleAuth()
gauth.LocalWebserverAuth() # Creates local webserver and auto handles 
#authentication.
drive = GoogleDrive(gauth)

file1 = drive.CreateFile(metadata={"title": "big.txt"})
file1.SetContentFile('big.txt')
file1.Upload()

文件“big.txt”与我的代码文件在同一个文件夹中。 当我运行它时，我得到了这个回溯：

During handling of the above exception, another exception occurred:

你能帮我找出哪里不对劲吗？ 提前多谢了。

Answer 1

必须用^{}而不是^{}设置内容：

file1 = drive.CreateFile({'title': 'Hello.txt'})
file1.SetContentFile(path_to_your_file)
file1.Upload()

如文档所述，如果您没有设置title和mimeType，它们将从您提供的文件的名称和类型自动设置。因此，如果要上载计算机上已存在的同名文件，可以执行以下操作：

file1 = drive.CreateFile()
file1.SetContentFile(path_to_your_file)
file1.Upload()

---

关于第二点，据我所知，GDrive无法将文件转换为其他格式。

Answer 2

基于documentation of PyDrive，我想说，您需要执行以下操作：

file_path = "path/to/your/file.txt"
file1 = drive.CreateFile()
file1.SetContentFile(file_path)
file1.Upload()

标题和内容类型元数据根据提供的文件路径自动设置。如果要提供其他文件名，请将其传递给CreateFile()，如下所示：

file1 = drive.CreateFile(metadata={"title": "CustomFileName.txt"})
