Django之前学习的的都是实现前后的不分离式的，Django也可以实现前后端分离式的开发，即视图中不使用render返回渲染的html页面，而是改用JsonResponse返回json字符串
1.创建testcaset应用，并将'testcase.apps.TestcaseConfig',添加到settings.py的INSTALLED_APPS中
2.models.py ----------表结构设计
1 from django.db import models
2
3 # Create your models here.
4 class BaseModel(models.Model):
5 create_time = models.DateTimeField(auto_now_add=True, verbose_name='创建时间')
6 update_time = models.DateTimeField(auto_now=True, verbose_name='修改时间')
7 is_delete = models.BooleanField(verbose_name='是否删除', default=False)
8
9 class Meta:
10 abstract = True #声明这个类只是用来继承的，不会创建这张表
11
12 class CaseSet(BaseModel):#用例集合和用例多对多关系
13 name = models.CharField(verbose_name='集合名称',max_length=60)
14 desc = models.CharField(verbose_name='集合描述',max_length=70)
15 class Meta:
16 db_table = 'case_set'
17 verbose_name = '用例集合表'
18 verbose_name_plural = verbose_name
19
20 def __str__(self):
21 return self.name
22
23 class Case(BaseModel):
24 title = models.CharField(verbose_name='用例标题',max_length=80,db_index=True)
25 desc = models.CharField(verbose_name='用例描述',max_length=120)
26 method_choice = [
27 [0,'get'],
28 [1,'post'],
29 [2,'put'],
30 [3,'delete']
31 ] #枚举
32 method = models.SmallIntegerField(choices=method_choice,verbose_name='请求方式',default=0)
33 url = models.URLField(max_length=50,verbose_name='请求url')
34 params = models.TextField(verbose_name='请求参数')
35 run_count = models.IntegerField(verbose_name='运行次数',default=0)
36 run_time = models.DateTimeField(verbose_name='运行时间',default=None)
37 case_set = models.ManyToManyField(CaseSet,db_constraint=False,verbose_name='用例集合')
38
39 class Meta:
40 db_table = 'case'
41 verbose_name = '用例表'
42 verbose_name_plural = verbose_name
43
44 def __str__(self):
45 return self.title
3.views.py---------------------视图实现返回接口
1 from django.forms import model_to_dict
2 from django.http import JsonResponse
3 from django.shortcuts import render
4 from django.views import View
5
6 from . import models
7
8
9 # Create your views here.
10 # django前后端分离，开发后端接口
11 def case_set(request):
12 # 添加用例集合
13 name = request.POST.get('name')
14 desc = request.POST.get('desc')
15 if name.strip() and desc.strip():
16 models.CaseSet.objects.create(name=name, desc=desc)
17 data = {'code': 0, 'msg': '添加成功'}
18 else:
19 data = {'code': -1, 'msg': '参数错误'}
20 return JsonResponse(data) # 通过JsonResponse类返回json字符串，data必须传字典，不然会报错
21
22
23 def case_set_all(req):
24 case_sets = models.CaseSet.objects.filter(is_delete=False)
25 data = []
26 for c in case_sets:
27 d = model_to_dict(c)
28 data.append(d)
29 response = {'code': 0, 'msg': '添加成功', 'data': data}
30 return JsonResponse(response, json_dumps_params={'ensure_ascii': False}) # 汉字不转义
31
32
33 # restful代码设计风格，不同的请求方式整个在一个方法中，不需要定义多个方法
34 def case_set_new(req):
35 if req.method == 'GET':
36 case_sets = models.CaseSet.objects.filter(is_delete=False)
37 data = []
38 for c in case_sets:
39 d = model_to_dict(c)
40 data.append(d)
41 response = {'code': 0, 'msg': '添加成功', 'data': data}
42 return JsonResponse(response, json_dumps_params={'ensure_ascii': False}) # 汉字不转义
43 elif req.method == 'POST':
44 name = req.POST.get('name')
45 desc = req.POST.get('desc')
46 if name.strip() and desc.strip():
47 models.CaseSet.objects.create(name=name, desc=desc)
48 data = {'code': 0, 'msg': '添加成功'}
49 else:
50 data = {'code': -1, 'msg': '参数错误'}
51 return JsonResponse(data) # 通过JsonResponse类返回json字符串
52 elif req.method == 'PUT':
53 pass
54 elif req.method == 'DELETE':
55 pass
56
57
58 # cvb
59 class CaseSet(View):
60 def get(self):
61 case_sets = models.CaseSet.objects.filter(is_delete=False)
62 data = []
63 for c in case_sets:
64 d = model_to_dict(c)
65 data.append(d)
66 response = {'code': 0, 'msg': '添加成功', 'data': data}
67 return JsonResponse(response, json_dumps_params={'ensure_ascii': False}) # 汉字不转义
68
69 def post(self, req):
70 name = req.POST.get('name')
71 desc = req.POST.get('desc')
72 if name.strip() and desc.strip():
73 models.CaseSet.objects.create(name=name, desc=desc)
74 data = {'code': 0, 'msg': '添加成功'}
75 else:
76 data = {'code': -1, 'msg': '参数错误'}
77 return JsonResponse(data) # 通过JsonResponse类返回json字符串
78
79 def put(self, req):
80 pass
81
82 def delete(self, req):
83 pass
4.testcase/urls.py-----------配置urls
1 from django.urls import path
2 from . import views
3
4 urlpatterns = [
5 path('add_case_set/',views.case_set),
6 path('case_set/',views.case_set_all),
7 path('case_set_new/',views.case_set_new)
8 ]
5.dj_test/urls.py-----------项目中配置url
1 from django.contrib import admin
2 from django.urls import path,include
3 from testcase import urls
4
5 urlpatterns = [
6 #引用子应用中的url
7 path('testcase/',include(urls))
8 ]
6.浏览器输入：http：//127.0.0.1：8000/testcase/case_set_new 或者postman进行访问
