AWS签名验证例程
awssig的Python项目详细描述
此库为向aws发出的请求提供签名验证 服务通常，这用于为aws服务提供模拟接口 或者通过代理主机重写aws请求。
当前源树可以在上找到 GitHub。
文档可在 pythonhosted。
目前只支持SigV4。
示例用法
>>> import awssig
>>> access_key = "AKIDEXAMPLE"
>>> secret_key = "wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY"
>>> key_mapping = { access_key: secret_key }
>>> v = awssig.AWSSigV4Verifier(
... request_method="GET",
... uri_path="/",
... query_string="a=foo&b=foo",
... headers={
... "Date": "Mon, 09 Sep 2011 23:36:00 GMT",
... "Host": "host.foo.com",
... "Authorization": (
... "AWS4-HMAC-SHA256 "
... "Credential=AKIDEXAMPLE/20110909/us-east-1/host/aws4_request, "
... "SignedHeaders=date;host, "
... "Signature=0dc122f3b28b831ab48ba65cb47300de53fbe91b577fe113edac383730254a3b"),
... },
... body=b"",
... region="us-east-1",
... service="host",
... key_mapping=key_mapping,
... timestamp_mismatch=None)
>>> try:
... v.verify()
... print("ok")
... except awssig.InvalidSignatureError as e:
... print("error: %s" % e)
ok
