问题描述
下面是我的代码.我复制了可互操作的访问密钥.客户端和密钥都来自同一页面.我在ClientAccess ID中以格式使用了客户端密钥，并使用了秘密进行哈希处理. 但是我收到错误消息说无效的参数.
Below is my code. I copied the interoperable access keys.. The client and secret both from the same page. I used client key in the ClientAccess ID in the form and secret for hashing. But i get the error saying invalid argument.
详细信息错误显示为无法使用POST创建存储桶"
下面是我使用的python代码.
Below is the python code i used.
import webapp2
import cgi
import datetime
import urllib
import base64
import hmac, hashlib
import sha
policy_document = '''{"expiration": "2016-06-16T11:11:11Z",
"conditions": [
["starts-with", "$key", "" ],
{"acl": "public-read" },
]
}'''
policy = base64.b64encode(policy_document).strip()
h = hmac.new('xxx', digestmod=sha.sha)
h.update(policy)
signature = base64.b64encode(h.digest())
class MainHandler(webapp2.RequestHandler):
def get(self):
self.response.write('<html><body>')
self.response.write('<form action="http://storage.googleapis.com/www.xyz.com" method="post" enctype="multipart/form-data">')
self.response.write('<input type="text" name="key" value="">')
self.response.write('<input type="hidden" name="bucket" value="www.xyz.com">')
#self.response.write('<input type="hidden" name="Content-Type" value="image/jpeg">')
self.response.write('<input type="hidden" name="GoogleAccessId" value="GOOGxxxxx">')
self.response.write('<input type="hidden" name="acl" value="public-read">')
self.response.write('<input type="hidden" name="success_action_redirect" value="http://www.linklip.com/storage.html">')
self.response.write('<input type="hidden" name="policy" value="%s">' % policy )
self.response.write('<input type="hidden" name="signature" value="%s">' % signature )
self.response.write('<input name="file" type="file">')
self.response.write('<input type="submit" value="Upload">')
self.response.write('</form>')
self.response.write('</body></html>')
app = webapp2.WSGIApplication([
('/', MainHandler)
], debug=True)
推荐答案
我遇到了同样的问题，在尝试尽可能接近文档之后，我发现错误的是我的文件输入是第一个形式的子项，而不是末尾.
I had the same issue, and after trying to be as close as possible to the documentation, I found that what was wrong is that my file input was the first child of the form instead of at the end.
不有效:
<form action="https://***.storage.googleapis.com" method="post" enctype="multipart/form-data">
<input type="file" name="file" />
<input type="hidden" name="signature" value="***" />
<input type="hidden" name="key" value="test/alexis.png" />
<input type="hidden" name="policy" value="***" />
<input type="hidden" name="Content-Type" value="image/png" />
<input type="hidden" name="GoogleAccessId" value="***@developer.gserviceaccount.com" />
<input type="hidden" name="bucket" value="***" />
<input type="hidden" name="success_action_status" value="201" />
<input type="submit" value="Upload">
</form>
作品:
<form action="https://***.storage.googleapis.com" method="post" enctype="multipart/form-data">
<input type="hidden" name="signature" value="***" />
<input type="hidden" name="key" value="test/alexis.png" />
<input type="hidden" name="policy" value="***" />
<input type="hidden" name="Content-Type" value="image/png" />
<input type="hidden" name="GoogleAccessId" value="***@developer.gserviceaccount.com" />
<input type="hidden" name="bucket" value="***" />
<input type="hidden" name="success_action_status" value="201" />
<input type="file" name="file" />
<input type="submit" value="Upload">
</form>
我仍然对为什么它能以这种方式而不是其他方式感到困惑...
I'm still puzzled about why it works this way and not the other...
