根据请求头 content-type 选择对应的解析器就请求体内容进行处理。
a. 仅处理请求头content-type为application/json的请求体
- urls.py
from django.conf.urls import url, include
from web.views.s5_parser import TestView
urlpatterns = [
url(r'test/', TestView.as_view(), name='test'),
]
- views.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.parsers import JSONParser
class TestView(APIView):
parser_classes = [JSONParser, ]
def post(self, request, *args, **kwargs):
print(request.content_type)
# 获取请求的值，并使用对应的JSONParser进行处理
print(request.data)
# application/x-www-form-urlencoded 或 multipart/form-data时，request.POST中才有值
print(request.POST)
print(request.FILES)
return Response('POST请求，响应内容')
def put(self, request, *args, **kwargs):
return Response('PUT请求，响应内容')
b. 仅处理请求头content-type为application/x-www-form-urlencoded 的请求体
- urls.py
from django.conf.urls import url, include
from web.views import TestView
urlpatterns = [
url(r'test/', TestView.as_view(), name='test'),
]
- views.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.parsers import FormParser
class TestView(APIView):
parser_classes = [FormParser, ]
def post(self, request, *args, **kwargs):
print(request.content_type)
# 获取请求的值，并使用对应的JSONParser进行处理
print(request.data)
# application/x-www-form-urlencoded 或 multipart/form-data时，request.POST中才有值
print(request.POST)
print(request.FILES)
return Response('POST请求，响应内容')
def put(self, request, *args, **kwargs):
return Response('PUT请求，响应内容')
c. 仅处理请求头content-type为multipart/form-data的请求体
- urls.py
from django.conf.urls import url, include
from web.views import TestView
urlpatterns = [
url(r'test/', TestView.as_view(), name='test'),
]
- views.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.parsers import MultiPartParser
class TestView(APIView):
parser_classes = [MultiPartParser, ]
def post(self, request, *args, **kwargs):
print(request.content_type)
# 获取请求的值，并使用对应的JSONParser进行处理
print(request.data)
# application/x-www-form-urlencoded 或 multipart/form-data时，request.POST中才有值
print(request.POST)
print(request.FILES)
return Response('POST请求，响应内容')
def put(self, request, *args, **kwargs):
return Response('PUT请求，响应内容')
- upload.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="http://127.0.0.1:8000/test/" method="post" enctype="multipart/form-data">
<input type="text" name="user" />
<input type="file" name="img">
<input type="submit" value="提交">
</form>
</body>
</html>
d. 仅上传文件
- urls.py
from django.conf.urls import url, include
from web.views import TestView
urlpatterns = [
url(r'test/(?P<filename>[^/]+)', TestView.as_view(), name='test'),
]
- views.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.parsers import FileUploadParser
class TestView(APIView):
parser_classes = [FileUploadParser, ]
def post(self, request, filename, *args, **kwargs):
print(filename)
print(request.content_type)
# 获取请求的值，并使用对应的JSONParser进行处理
print(request.data)
# application/x-www-form-urlencoded 或 multipart/form-data时，request.POST中才有值
print(request.POST)
print(request.FILES)
return Response('POST请求，响应内容')
def put(self, request, *args, **kwargs):
return Response('PUT请求，响应内容')
- upload.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="http://127.0.0.1:8000/test/f1.numbers" method="post" enctype="multipart/form-data">
<input type="text" name="user" />
<input type="file" name="img">
<input type="submit" value="提交">
</form>
</body>
</html>
e.同时多个Parser
当同时使用多个parser时，rest framework会根据请求头content-type自动进行比对，并使用对应parser
- urls.py
from django.conf.urls import url, include
from web.views import TestView
urlpatterns = [
url(r'test/', TestView.as_view(), name='test'),
]
- views.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.parsers import JSONParser, FormParser, MultiPartParser
class TestView(APIView):
parser_classes = [JSONParser, FormParser, MultiPartParser, ]
def post(self, request, *args, **kwargs):
print(request.content_type)
# 获取请求的值，并使用对应的JSONParser进行处理
print(request.data)
# application/x-www-form-urlencoded 或 multipart/form-data时，request.POST中才有值
print(request.POST)
print(request.FILES)
return Response('POST请求，响应内容')
def put(self, request, *args, **kwargs):
return Response('PUT请求，响应内容')
f. 全局使用
- setting.py
REST_FRAMEWORK = {
'DEFAULT_PARSER_CLASSES':[
'rest_framework.parsers.JSONParser'
'rest_framework.parsers.FormParser'
'rest_framework.parsers.MultiPartParser'
]
}
- urls.py
from django.conf.urls import url, include
from web.views import TestView
urlpatterns = [
url(r'test/', TestView.as_view(), name='test'),
]
- views.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.views import APIView
from rest_framework.response import Response
class TestView(APIView):
def post(self, request, *args, **kwargs):
print(request.content_type)
# 获取请求的值，并使用对应的JSONParser进行处理
print(request.data)
# application/x-www-form-urlencoded 或 multipart/form-data时，request.POST中才有值
print(request.POST)
print(request.FILES)
return Response('POST请求，响应内容')
def put(self, request, *args, **kwargs):
return Response('PUT请求，响应内容')
注意：个别特殊的值可以通过Django的request对象 request._request 来进行获取
