三、auth自定义授权
客户端代码：
import requests import hashlib import time current_time = time.time() #自意义的字符串app_id,和服务端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形式传值 # data={'username':'1123','pwd': '666'}, # POST形式传值 # headers={'a':'123'} # 请求头数据 # )
服务端代码：
from django.shortcuts import render,HttpResponse from django.views.decorators.csrf import csrf_exempt,csrf_protect import hashlib import time #自定义的字符串 ck='8kasoimnasodn8687asdfkmasdf' #5秒钟的授权列表 auth_list = [] @csrf_exempt def asset(request): auth_key_time = request.META.get('HTTP_AUTHKEY') auth_key_client,client_ctime = auth_key_time.split('|') server_current_time = time.time() if server_current_time - 5 > float(client_ctime): #太久远了 return HttpResponse('时间太久远了') if auth_key_time in auth_list: #已经访问过了 return HttpResponse('你来晚了') key_time = '%s|%s' %(ck,client_ctime) m = hashlib.md5() m.update(bytes(key_time,encoding='utf-8')) authkey = m.hexdigest() if authkey != auth_key_client: return HttpResponse('授权失败') auth_list.append(auth_key_time) if request.method == 'POST': import json print(authkey) host_info = json.loads(str(request.body,encoding='utf-8')) print(host_info) return HttpResponse('授权成功') def test(request): # print(request.POST,type(request.POST)) # from django.http.request import QueryDict response = render(request,'index.html') response.set_signed_cookie('kkkk','vvvv',salt='asdf') return response
