django设置并获取cookie/session，文件上传，ajax接收文件，post/get请求及跨域请求等的方法

django设置并获取cookie/session，文件上传，ajax接收文件等的方法：

views.py文件：

from django.shortcuts import render,HttpResponse,redirect

import datetime

import json

from .setMongodb import pinglun

from bson import ObjectId

# Create your views here.

def index(request):

    # print(render(request,'index.html').__dict__['_container'][])

    print(render(request, 'index.html').content)

    return render(request, 'index.html')

def product(request,id):

    return render(request, 'product.html',{'pid':id})

def article(request,aid):

    return render(request, 'article.html', {'aid': aid})

#ajax返回数据

def jsonApi(request):

    dictobj = {'title': '标题'}

    a = HttpResponse(json.dumps(dictobj, ensure_ascii=False))

    # 允许你的域名来获取我的数据

    a['Access-Control-Allow-Origin'] = "*"

    # 允许你携带Content-Type请求头

    a['Access-Control-Allow-Headers'] = "Content-Type"

    return a

#GET/POST

def methodApi(request):

    # http = 'http://localhost:8000/methodApi?abc=123'

    if request.method=='GET':

        request.GET.get('abc')  # ===>

        request.POST.get('username')  # ===>admin

    return HttpResponse('methodApi')

#设置cookie

def setcookie(request):

    a = HttpResponse('')

    # 设置cookies超过10秒失效，写法

    a.set_cookie('isLogin', 'true', max_age=)

    # 从登录10秒后失效，写法

    current_time = datetime.datetime.utcnow()

    current_data = current_time + datetime.timedelta(seconds=)

    a.set_cookie('key', 'value', expires=current_data)

    return a

#获取cookie的写法

def getcookie(request):

    islogin = request.COOKIES.get('isLogin')

    return HttpResponse(redirect('index'))

#设置session

def setsession(request):

    request.session['username'] = '老王'

    return HttpResponse('setsession')

#获取seseion

def getsession(request):

    # request.session.get('username')

    return HttpResponse(request.session['username'])

# 设置文件上传

def uploadfile(request):

    if request.method == 'GET':

        return render(request, 'upload.html')

    else:

        obj = request.FILES.get('files')

        print(obj)

        print(obj.__dict__)

        # print(obj.name,obj.size)  #读取文件名称和大小，返回后台

        f = open('./static/upload/'+obj.name, 'wb')

        for chunk in obj.chunks():

            f.write(chunk)

        f.close()

        return HttpResponse('图片上传成功')

def pinglunList(request):

    result =  pinglun.find()

    resList = []

    for item in result:

        item['_id'] = str(item['_id'])

        resList.append(item)

    # print(resList)

    jsonStr = json.dumps(resList,ensure_ascii=False)

    # print(jsonStr)

    a = HttpResponse(jsonStr)

    a['Access-Control-Allow-Origin'] = "*"

    # 允许你携带Content-Type请求头

    a['Access-Control-Allow-Headers'] = "Content-Type"

    return a

def addContent(request):

    print(request.GET.get('username'))

    contentDict = {

        'username': request.GET.get('username'),

        'headerimg': request.GET.get('headerimg'),

        'content': request.GET.get('content'),

        'zanNum': request.GET.get('zanNum')

    }

    print(contentDict)

    pinglun.insert(contentDict)

    a = HttpResponse('ok')

    a['Access-Control-Allow-Origin'] = "*"

    # 允许你携带Content-Type请求头

    a['Access-Control-Allow-Headers'] = "Content-Type"

    return a

def addzan(request):

    print(request.GET.get('_id'))

    _id = request.GET.get('_id')

    # res1 = pinglun.find_one({'_id': _id})

    res = pinglun.update({'_id': ObjectId(_id)}, {'$inc': {'zanNum': }})

    print(res)

    a = HttpResponse('ok')

    a['Access-Control-Allow-Origin'] = "*"

    # 允许你携带Content-Type请求头

    a['Access-Control-Allow-Headers'] = "Content-Type"

    return a
