创建新的云存储桶时获取"HTTP Error 400: Bad Request"

Question

我正在尝试使用GCP API创建一个google存储桶。我收到HTTP错误400：错误的请求错误。不确定我哪里错了。但是curl命令有效。

平台

Python 3.4.3/Uubuntu 14.04.5 LTS

程序：

导入urlib.request导入urlib.parse导入ssl导入http.clientauth＝auth＝"；承载人XXXXXXXXXXXX"；

def create_bkt(prj):
quoted_prj = urllib.parse.quote(prj, safe='')
url = 'https://storage.googleapis.com/storage/v1/b?project=%s' % (quoted_prj)
headers = {"Authorization": auth,
"Accept": "application/json",
"Content-Type": "application/json"}
context = ssl._create_unverified_context()
values = {"name":"bkt1"}
data = urllib.parse.urlencode(values).encode("utf-8")
req = urllib.request.Request(url, data, headers)
response = urllib.request.urlopen(req, context=context)
if __name__=="__main__":
call1('prj1')

curl (works without any issue):
curl -v --request POST 'https://storage.googleapis.com/storage/v1/b?project=prj1' --header 'Authorization: Bearer XXXXXXXXXXXXX' --header 'Accept: application/json'  --header 'Content-Type: application/json' --data '{"name":"bkt1"}' --compressed

您的值是dict，而不是JSON。

试试这个

import json
def create_bkt(prj):
quoted_prj = urllib.parse.quote(prj, safe='')
url = 'https://storage.googleapis.com/storage/v1/b?project=%s' % (quoted_prj)
headers = {"Authorization": auth,
"Accept": "application/json",
"Content-Type": "application/json"}
context = ssl._create_unverified_context()
values = {"name":"bkt1"}
data = urllib.parse.urlencode(json.dumps(values)).encode("utf-8")
req = urllib.request.Request(url, data, headers)
response = urllib.request.urlopen(req, context=context)
...
