urls

因为尝试些API接口，所以在目录下新建了一个views文件；

from django.conf.urls import urlfrom taobao import views, views_apiurlpatterns = [    url(r'^$', views.index),   url(r'^api/',views_api.classify)]

modles

from django.db import modelsclass goods(models.Model):    category = models.IntegerField('分类',default=0)    goods_id = models.CharField('商品ID',max_length=10)    goods_name = models.CharField('商品名',max_length=100,default='')    goods_price = models.DecimalField('商品价格',max_digits=10,decimal_places=2)    goods_Stock = models.IntegerField('商品库存',default=100)    sales_Volume = models.IntegerField('销量',default=0)    goods_introduce = models.CharField('商品简介',max_length=250,default='')    def __str__(self):        return self.goods_name

views_api

from taobao.models import goodsfrom django.http import JsonResponsefrom django.core.paginator import Paginator ,PageNotAnInteger ,EmptyPagefrom django.views.decorators.csrf import  csrf_exempt#分类展示#测试的时候我先把csrf关了@csrf_exemptdef classify(req):    context ={'status':200}    #获取 post 数据    type = req.POST.get('type','')    page = req.POST.get('page','')    context['type'] , context['page'] = type ,page    #根据类别在数据库找到相应数据    if type == '0':        goods_list = goods.objects.order_by('sales_Volume').all()    else:        goods_list = goods.objects.all().filter(category = int(type)).order_by('sales_Volume').all()    #数据为空直接返回json    if goods_list == None:        return JsonResponse({'status':10021,'message':'parameter error'})    #分页    paginator = Paginator(goods_list,8)    try:        goodss = paginator.page(int(page))    except PageNotAnInteger:        goodss = paginator.page(1)    except EmptyPage:        goodss = paginator.page(paginator.num_pages)    #一页商品的个数，是否有前一页，是否有后一页    context['queryNum'],context['hasPrevios'],context['hasNext'] = len(goodss),goodss.has_previous(),goodss.has_next()    #将数据存入data[]    data = []    if goodss:        for i in goodss:            good = {}            good['goods_id'] = i.goods_id            good['goods_name'] = i.goods_name            good['goods_price'] = i.goods_price            good['goods_stock'] = i.goods_Stock            good['sales_volume'] = i.sales_Volume            good['goods_introduce'] = i.goods_introduce            data.append(good)        # 将data存进context        context.update({'data':data})        # 返回json        return JsonResponse(context)    else:        return  JsonResponse({'status':10022,'message':'query goods isempty'})

接口测试

这里使用到postman；
用chrome浏览器添加扩展程序Postman，并安装桌面应用。
应用页面如下：

1. 填上url。
2. 选择传输数据方式。
3. 点击下方body，选择form-data
4. 输入参数 “type” = 1,”page” = 1，点击send。

下方返回json数据
