我将CSV文件test.csv
上传到Google云端存储的存储分区。得到的public_url
是这样如何从谷歌云存储桶下载对象?
https://storage.googleapis.com/mybucket/test-2017-04-11-025727.csv
原来`test.csv”有一些包含行数和列数这样
6,148,72,35,0,33.6,0.627,50,1
8,183,64,0,0,23.3,0.672,32,1
...
...
我参照书架教程上传的文件 - >https://github.com/GoogleCloudPlatform/getting-started-python没有6-pubsub
。上传的文件将添加时间戳保存。
现在我想下载,我上传到水桶使用requests
这是我一直在工作的文件。原始样本为6-pubsub/bookshelf/crud.py
。以下是我基于原始样本编辑的脚本。
from machinelearning import get_model, oauth2, storage, tasks
from flask import Blueprint, current_app, redirect, render_template, request, session, url_for
import requests
import os
...
...
crud = Blueprint('crud', __name__)
save_folder = 'temp/'
def upload_csv_file(file):
...
...
return public_url
...
...
@crud.route('/add', methods=['GET', 'POST'])
def add():
data = request.form.to_dict(flat=True)
# This will upload the file that I pushed from local directory to GCS
if request.method == 'POST':
csv_url = upload_csv_file(request.files.get('file'))
if csv_url:
data['csvUrl'] = csv_url
# I think this is not working. This should download back the file and save it to a temporary folder inside current working directory
response = requests.get(public_url)
if not os.path.exists(save_folder):
os.makedirs(save_folder)
with open(save_folder + 'testdata.csv', 'wb') as f:
f.write(response.content)
...
...
我打开的文件夹temp
并检查testdata.csv
。它在CSV文件中向我显示了这样的错误。
<?xml version='1.0' encoding='UTF-8'?><Error><Code>AccessDenied</Code><Message>Access denied.</Message><Details>Anonymous users does not have storage.objects.get access to object mybucket/test-2017-04-11-025727.csv.</Details></Error>
我希望testdata.csv
会有像test.csv
相同的内容,但事实并非如此。
我已经在config.py
上重新检查了我的OAuth客户端和密钥桶ID,但仍然存在错误。
我该如何解决这类错误?
谢谢您的高级。
这听起来像你的对象是不能公开访问。您需要将其标记为公共可读,无论是在控制台中还是在上载时设置ACL。 –
