通过python上传JSON到谷歌云存储

Question

我想上传一个JSON我必须谷歌云存储。我可以手动完成，所以我知道它的工作原理，但现在想写一个自动执行它的python脚本。

import boto 
import gcs_oauth2_boto_plugin 
import os 
import shutil 
import StringIO 
import tempfile 
import time 

from google.cloud import storage 
from google.cloud.storage import blob 

client = storage.Client(project='dataworks-356fa') 
bucket = client.get_bucket('dataworks-356fa-backups') 
blob = bucket.blob('t.json') 
with open('t.json', 'rb') as f: 
    blob.upload_from_file('f') 

是我到目前为止的代码，这是我得到的错误。

Traceback (most recent call last): 
    File "uploadcloud.py", line 16, in <module> 
    blob.upload_from_file('f') 
    File "/Library/Python/2.7/site-packages/google/cloud/storage/blob.py", line 891, in upload_from_file 
    client, file_obj, content_type, size, num_retries) 
    File "/Library/Python/2.7/site-packages/google/cloud/storage/blob.py", line 815, in _do_upload 
    client, stream, content_type, size, num_retries) 
    File "/Library/Python/2.7/site-packages/google/cloud/storage/blob.py", line 634, in _do_multipart_upload 
    data = stream.read() 
AttributeError: 'str' object has no attribute 'read'

你应该传递一个打开的文件，以upload_from_file不串，只是改变

with open('t.json', 'rb') as f: 
    blob.upload_from_file(f)
