这是一个专门为django-rest-framework设计的前端验证框架
首先安装
pip install djangorestframework-jwt
src/blog/settings.py
"DEFAULT_AUTHENTICATION_CLASSES": (
#'rest_framework.authentication.SessionAuthentication',
'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
"DEFAULT_PERMISSION_CLASSES": (
'rest_framework.permissions.IsAuthenticatedOrReadOnly',
'rest_framework.permissions.IsAuthenticated',
我们来做一个测试
将IsAuthenticatedOrReadOnly'改为IsAuthenticated，不允许浏览
"DEFAULT_AUTHENTICATION_CLASSES": (
#'rest_framework.authentication.SessionAuthentication',
'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
"DEFAULT_PERMISSION_CLASSES": (
'rest_framework.permissions.IsAuthenticated',
去掉CommentsLisView的授权
class CommentListAPIView(ListAPIView):
serializer_class = CommentListSerializer
# permission_classes = [AllowAny]
再次访问 http://127.0.0.1:8000/api/comments/
HTTP 401 Unauthorized
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
WWW-Authenticate: JWT realm="api"
{
"detail": "Authentication credentials were not provided."
}
可以看到授权模块用的是JWT
如果DEFAULT_AUTHENTICATION_CLASSES改回到SessionAuthentication'，报错如下
HTTP 403 Forbidden
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
{
"detail": "Authentication credentials were not provided."
}
我们创建URL去处理token
src/blog/urls.py
from rest_framework_jwt.views import obtain_jwt_token
urlpatterns = [
url(r'^api/auth/token/', obtain_jwt_token),
访问 http://127.0.0.1:8000/api/auth/token/
执行post abcd/abcd, 返回结果如下
HTTP 200 OK
Allow: POST, OPTIONS
Content-Type: application/json
Vary: Accept
{
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc1MDMyN30.5wws5JaW4yBp8Iky5FTX6x91URZho-JQ750loqzTTrE"
}
可以用下面的命令行
curl -X POST -d "username=abcd&password=abcd" http://127.0.0.1:8000/api/auth/token/
返回
C:\Users\Administrator>curl -X POST -d "username=abcd&password=abcd" [http://127.0.0.1](http://127.0.0.1):8000/api/auth/token/
{"token":" eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc1MTY1Mn0.BDMx3uMZFrYYCTWmQVxV3oGICu_XS3cDBl7cMQL0yT8"}
如果不添加token信息，浏览评论时，会跟前面一样返回错误"Authentication credentials were not provided."
C:\Users\Administrator> curl [http://127.0.0.1](http://127.0.0.1):8000/api/comments/
{"detail":"Authentication credentials were not provided."}
添加token信息的格式为 ·curl -H "Authorization: JWT <your_token>" [http://localhost:8000/protected-url/](http://localhost:8000/protected-url/)
本例生成如下
curl -H "Authorization: JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc1MTY1Mn0.BDMx3uMZFrYYCTWmQVxV3oGICu_XS3cDBl7cMQL0yT8" http://127.0.0.1:8000/api/comments/
返回结果
C:\Users\Administrator>curl -H "Authorization: JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc1MTY1Mn0.BDMx3uMZFrYYCTWmQVxV3oGICu_XS3cDBl7cMQL0yT8" http://127.0.0.1:8000/api/comments/
{"count":7,"next":"[http://127.0.0.1](http://127.0.0.1):8000/api/comments/?page=2","previous":null,"results":[{"url":"[http://127.0.0.1](http://127.0.0.1):8000/api/comments/53","id":53,"content":"reply ++","reply_count":
1},{"url":"[http://127.0.0.1](http://127.0.0.1):8000/api/comments/52","id":52,"content":"this is comment ++","reply_count":0},{"url":"[http://127.0.0.1](http://127.0.0.1):8000/api/comments/51","id":51,"content":"this is
comment","reply_count":3},{"url":"[http://127.0.0.1](http://127.0.0.1):8000/api/comments/48","id":48,"content":"comments 2 on test","reply_count":2}]}
再次执行，按理由可以返回实际结果，实际上没有，后面要查一下
curl http://127.0.0.1:8000/api/comments/
创建post，名字为curl
换了Header为”json”,
Token有有效期，超过时间了需要重新获取 {"detail":"Signature has expired."}，可以通过下面配置延迟时间
import datetime
JWT_AUTH = {
'JWT_EXPIRATION_DELTA': datetime.timedelta(seconds=300),
}
curl -X POST -H "Authorization: JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc5MzMyMn0.HQbC7mrsb20bRe-m00NdB-m-GZ1leFX1UGcWyjei18o" -H "Content-Type: application/json" -d '{"content":"abcd", "title":"curl","publish":"2018-01-01"}' http://127.0.0.1:8000/api/posts/create
HTTP 200 OK
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
{
"url": "[http://127.0.0.1](http://127.0.0.1):8000/api/posts/curl/",
"title": "curl",
"slug": "curl",
"publish": "2018-01-01",
"user": {
"username": "abcd",
"email": "abcd@abc.com",
"first_name": "",
"last_name": ""
},
"image": null,
"content": "abcd",
"html": "<p>abcd</p>\n",
"comments": []
}
给这个post创建comments
curl -X POST -H "Authorization: JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc5MzMyMn0.HQbC7mrsb20bRe-m00NdB-m-GZ1leFX1UGcWyjei18o" -H "Content-Type: application/json" -d '{"content":"abcd"}' "http://127.0.0.1:8000/api/comments/create/?slug=curl&type=post"
注意：网址用双引号括起来，不加或用单引号会报错 {"non_field_errors":["This is not a valid content type"]}系统找不到指定的文件。
返回结果
{"id":61,"content":"abcd","timestamp":"2018-07-28T15:14:32.726000Z"}
查看这个comments http://127.0.0.1:8000/api/comments/61
HTTP 200 OK
Allow: GET, PUT, DELETE, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
{
"id": 61,
"user": {
"username": "abcd",
"email": "abcd@abc.com",
"first_name": "",
"last_name": ""
},
"content": "abcd",
"reply_count": 0,
"replies": [],
"timestamp": "2018-07-28T15:14:32.726000Z",
"content_object_url": "/api/posts/curl/"
}
添加子评论
curl -X POST -H "Authorization: JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFiY2QiLCJ1c2VyX2lkIjo3LCJlbWFpbCI6ImFiY2RAYWJjLmNvbSIsImV4cCI6MTUzMjc5MzMyMn0.HQbC7mrsb20bRe-m00NdB-m-GZ1leFX1UGcWyjei18o" -H "Content-Type: application/json" -d '{"content":"reply of abcd"}' http://127.0.0.1:8000/api/comments/create/?slug=curl&type=post&parent_id=61
返回结果
{"id":62,"content":"reply of abcd","timestamp":"2018-07-28T15:19:24.935000Z"}
刷新http://127.0.0.1:8000/api/comments/61，下面新添加了子评论
HTTP 200 OK
