pipenv install restful_client_lite

pip:
pip install restful_client_lite

Dev
pipenv:
pipenv install -e git+https://github.com/huandzh/restful-client-lite#egg=restful-client-lite

Usage
Assume that we have a restful api requiring Authorization:<token> in the header and using etag to control writes.
Create an API client:
from restful_client_lite import APIClient
api = APIClient("<api_root>", {"token": "<token>"})

Get from url:
res_get = api.get("<url>")

Post to url:
res_post = api.post("<url>", data={"<key>": "<value>"})

Patch url:
res_patch = api.patch("<url>", "<etag>", data={"<key>": "<value>"})

Patch url (fetch etag automatically in advance):
res_patch = api.patch_auto_etag("<url>", data={"<key>": "<value>"})

Delete url:
res_delete = api.delete("<url>", "<etag>")

Delete url (fetch etag automatically in advance):
res_delete = api.delete_auto_etag("<url>")

Subclass APIClient to create custom api client:
def sign(url):
"""some function return signature"""
...
return <signed url>

class CustomAPIClient(APIClient):
"""custom api client"""

def auth_headers(self, f: Callable) -> Callable:
"""custom auth headers"""
@wraps(f)
def wrapper(*args, **kwargs):
headers = kwargs.get("headers", {}).copy()
url = args[0]
headers.update({"Signature": sign(url)})
kwargs["headers"] = headers
return f(*args, **kwargs)

3rd-party APIs
aliyun api gateway
AliyunApiGatewayClient :

support GET from aliyun-api-gateway apis (apis may generated by DataService)
handle authorization headers
doesn't sort url params

from restful_client_lite.contrib.aliyun import AliyunApiGatewayClient
api = AliyunApiGatewayClient(
'<api_root>',
{"app_id": '<app_id>',
"app_secret": '<app_secret>'})
# make sure params in <url> are sorted
res = api.get('<url>')

wangduoyun api
WangduoyunApiClient:

support account apis
support graphql apis

# client adds required authorization data for POST
api = WangduoyunApiClient(
"<api_root>",
{"user_key": "<user_key>",
"user_secret": "<user_secret>"})
res = api.post("<url>")

# client provides `get_sign` to get authorization params
api = WangduoyunApiClient(
"<api_root>",
{"user_key": "<user_key>",
"user_secret": "<user_secret>"})
sign, timestamp = api.get_sign()
url = "?user_key={user_key}&timestamp={timestamp}&sign={sign}&source_id={source_id}&query={query}".format(
user_key=api.auth['user_key'],
timestamp=timestamp,
sign=sign,
source_id="<source_id>",
query="<query>")
res = api.get(url)
