三、auth自定義授權
客戶端代碼：
import requests import hashlib import time current_time = time.time() #自意義的字符串app_id,和服務端ck一致 app_id =‘8kasoimnasodn8687asdfkmasdf‘ app_id_time = "%s|%s" % (app_id,current_time,) m = hashlib.md5() m.update(bytes(app_id_time,encoding=‘utf-8‘)) authkey = m.hexdigest() authkey_time="%s|%s" % (authkey,current_time,) print(authkey_time) host_data = { ‘status‘:True, ‘data‘:{ ‘hostname‘:‘c1.com‘, ‘disk‘:{‘status‘:True,‘data‘:‘xxx‘}, ‘mem‘:{‘status‘:True,‘data‘:‘xxx‘}, ‘nic‘:{‘status‘:True,‘data‘:‘xxx‘}, }, } response=requests.post( url=‘http://127.0.0.1:8000/api/asset/‘, json=host_data, headers={‘authkey‘:authkey_time}, ) print(response.text) # requests.get(url=‘http://127.0.0.1:8000/api/asset/?k1=123‘) # requests.get(url=‘http://127.0.0.1:8000/api/asset/‘,params={‘k1‘:‘v1‘,‘k2‘:‘v2‘}) # requests.post( # url=‘http://127.0.0.1:8000/api/asset/‘,# params={‘k1‘:‘v1‘,‘k2‘:‘v2‘}, # GET形式傳值 # data={‘username‘:‘1123‘,‘pwd‘: ‘666‘}, # POST形式傳值 # headers={‘a‘:‘123‘} # 請求頭數據 # )
服務端代碼：
