Django中使用RPC协议

一、使用所需环境
pip install django-json-rpc

二、在django项目settings配置文件中注册 'jsonrpc'

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'jsonrpc',
    'app',
]

三、视图中调用

apis.py

from rest_framework import generics
from app.models import Person
from app.serializers import PersonSerializer
from jsonrpc import jsonrpc_method

# http
class PersonAPI(generics.ListCreateAPIView):
    queryset = Person.objects.all()
    serializer_class = PersonSerializer

# rpc
@jsonrpc_method('person')
def person(request):
    queryset = Person.objects.all()
    res = PersonSerializer(queryset, many=True).data
    return res

四、注册路由

3.Add the JSON-RPC mountpoint and import your views

urls.py

from django.urls import path
from jsonrpc import jsonrpc_site
from app.apis import PersonAPI

urlpatterns = [
    path('person/', PersonAPI.as_view()),
    path('rpc-person/', jsonrpc_site.dispatch),
]

五、rpc调用对比api调用

### api调用
import requests

url = "http://127.0.0.1:8000/person/"
res = requests.get(url)
print(res.json())

返回值

[
       {'id': 1, 'name': 'one', 'age': 22}, 
       {'id': 2, 'name': 'two', 'age': 23}, 
       {'id': 3, 'name': 'three, 'age': 24}
]

### rpc调用
from jsonrpc.proxy import ServiceProxy

url = "http://127.0.0.1:8000/rpc-person/"
s = ServiceProxy(url)
res = s.person.data()
print(res)

返回值

{
    'id': '425d9d70-ccbe-11ea-a8ca-7470fd0bd93a',
    'error': None, 
    'result': [
        {'id': 1, 'name': 'one', 'age': 22}, 
        {'id': 2, 'name': 'two', 'age': 23}, 
        {'id': 3, 'name': 'three, 'age': 24}
    ], 
    'jsonrpc': '1.0'
}
