图书管理系统后端接口

1.图书管理系统后端接口

1.1 books/models.py 中设置表

from django.db import models
class Books(models.Model):
    btitle = models.CharField(max_length= 20 )
    bpub_date = models.DateField()
    bread = models.IntegerField()
    bcomment = models.IntegerField()
    is_delete = models.BooleanField(default=False)

1.2 urls.py 中设置路由

from django.urls import path

from books.views import *

urlpatterns = [
    path('book/', BooksView.as_view()),
]

1.3 book/views.py 视图函数

from django.http import JsonResponse

class BooksView(View):
    def get(self, request):
        books = Books.objects.filter(is_delete=False)
        book_list = books.values('id','btitle','bpub_date','bread','bcomment')
        book_list = list(book_list)
        data = {
        "code": 0 ,
        "msg": "success",
        "books": book_list
        }
        return JsonResponse(data)
    def post(self, request):
        body_json = request.body.decode()
        body_dict = json.loads(body_json)
        btitle = body_dict.get('btitle')
        bpub_date = body_dict.get('bpub_date')
        bread = body_dict.get('bread')
        bcomment = body_dict.get('bcomment')
        book = Books(btitle=btitle, bpub_date=bpub_date, bread=bread,
        bcomment=bcomment)
        book.save()
        return JsonResponse({"code": 0 , "msg": "success"})
    def put(self, request):
        body_json = request.body.decode()
        body_dict = json.loads(body_json)
        id = body_dict.get('id')
        btitle = body_dict.get('btitle')
        bpub_date = body_dict.get('bpub_date')
        bread = body_dict.get('bread')
        bcomment = body_dict.get('bcomment')
        book = Books.objects.get(id=id)
        book.btitle = btitle
        book.bpub_date = bpub_date
        book.bread = bread
        book.bcomment = bcomment
        book.save()
        return JsonResponse({"code": 0, "msg": "success"})

    def delete(self, request):
        body_json = request.body.decode()

        body_dict = json.loads(body_json)
        id = body_dict.get('id')
        book = Books.objects.get(id=id)
        book.is_delete = True
        book.save()
        return JsonResponse({"code": 0, "msg": "success"})

2.测试接口

2.1 测试获取所有图书接口

http://127.0.0.1:8000/book/

返回结果

2.2 测试创建图书接口

http://127.0.0.1:8000/book/
.postman测试提交数据
{

"btitle":"红楼梦",
"bpub_date":"2018-02-04",
"bread": 100 ,
"bcomment": 0
}

结果

2.3 测试修改图书接口

http://127.0.0.1:8000/books/

postman测试提交数据

 

{

"id":5,

"btitle":"红楼梦",

"bpub_date":"2018-02-04",

"bread":100,

"bcomment":0

}

 

结果

2.4 测试删除数据接口

http://127.0.0.1:8000/books/
