python - 使用 Python api-client-library 将文本文件上传到 Google Cloud Storage。适用于图像，不适用于文本

Question

我正在尝试将文本文件从我的非 Google 服务器上传到 Google 存储空间。当文件是图像 (png) 时它有效，但当它是文本文件时则无效。我明白

<HttpError 400 when requesting https://www.googleapis.com/upload/storage/v1/b/my_bucket_name/o?uploadType=resumable&alt=json&predefinedAcl=publicRead&name=media%2Fmy_file.txt returned "Bad Request"

.

credentials = GoogleCredentials.get_application_default()
google_service = build('storage', 'v1', credentials=credentials)

bucket = "my_bucket_name"

filename = "/home/path/my_image.png"
filename_new = "media/my_image.png"

# Fails with txt file instead of image
#filename = "/home/path/my_file.txt"
#filename_new = "media/my_file.txt"

media = MediaFileUpload(filename, chunksize=4194304, resumable=True)
req = google_service.objects().insert(bucket=bucket,
        name=filename_new ,
        media_body=media,
        body={"cacheControl": "public,max-age=31536000"},
        predefinedAcl='publicRead')
resp = None
while resp is None:
    status, resp = req.next_chunk()

Answer 1

关键是要包含 mimetype:

filename = "/home/path/my_file.txt"
media = MediaFileUpload(filename, chunksize=4194304,  mimetype='plain/text', resumable=True)

其他:

mimetype='image/png'

mimetype='application/gzip'
