Auth check and more plugins for fastApi

Auth check and more plugins for fastApi

Getting Started

provide SDK in the following programming languages:

• Python

Python

1. Install the fastApi-context package:

   pip install fastApi-context
   

2. Initialize your fastapi client

   from fastapi import FastAPI
   
   app = FastAPI()
   

3. Configure plugins

   1. JwtAuthPlugin

      pip install fastApi-context[jwt]
      

   • for JWT authentication you can use the JwtAuthPlugin plugin. This plugin allows you to configure JWT authentication for your FastAPI application.

      from fastapi_context.config import JWTAuthPluginConfig
      from fastapi_context.plugins.auth_plugin import JwtAuthPlugin
      
      jwt_auth_plugin = JwtAuthPlugin(
               auth_plugin_config=JWTAuthPluginConfig(
               key="jwt payload key in context",
               url_white_list=["url white list"],
               user_class=None,  # user class for decode jwt payload
               get_token="token",  # get jwt token way, value is string or callable
               jwt_secret="Your App Jwt secret",
               jwt_algorithms=["HS256"],  # Your App Jwt algorithms
           )
       )
     

   2. RedisAuthPlugin

      pip install fastApi-context[redis]
      

   • for Redis authentication you can use the RedisAuthPlugin plugin. This plugin allows you to configure Redis authentication for your FastAPI application.

     from fastapi_context.config import RedisConfig, RedisAuthPluginConfig
     from fastapi_context.plugins.auth_plugin import RedisAuthPlugin
     
     redis_auth_plugin = RedisAuthPlugin(
              auth_plugin_config=RedisAuthPluginConfig(
              key="redis payload key in context",
              url_white_list=["url white list"],
              user_class=None,  # user class for decode jwt payload
              get_token="token",  # get jwt token way, value is string or callable
              redis_token_key_prefix="your redis token key prefix",
              # config redis client
              # redis_client_function or redis_config must be provided. At least one of these two parameters needs to be set in order for the configuration to work correctly.   
              redis_config=RedisConfig(
                  host=settings.Redis.HOST,
                  port=settings.Redis.PORT,
                  db=settings.Redis.TOKEN_DB_NUM,
                  password=settings.Redis.PASSWORD,
                  decode_responses=True,
              ),
             # sync or async both support, see redis.Redis or redis.asyncio.client.Redis, Prioritize async selection
             # redis_client_function=function,
           )
     )
     

4. Register middleware

   from fastapi_context.config import ContextConfig, JsonResponseConfig
   from fastapi_context.exceptions import ContextMiddlewareError
   from fastapi_context.context_middleware import FastAPiContextMiddleware
   from starlette.responses import JSONResponse
   from pydantic import BaseModel, Field
   
   # when you set `JSONResponse` for error_response, you need to define a custom response model or use default model `JsonResponseConfig`.
   #  You can define your own BaseModel and implement a custom return type by overriding the create_model_by_error method.
   class MyJsonResponseConfig(BaseModel):
      status: int = Field(default=0, title="status")
      data: Any = Field(default=None, title="data")
      msg: str = Field(default="", title="message")
     
      @classmethod
      def create_model_by_error(cls, error: ContextMiddlewareError):
          """
          create json data by context error
          """
          return cls(status=error.error_code, data=error.data, msg=error.message)
   
   app.add_middleware(
       FastAPiContextMiddleware,
           context_config=ContextConfig(
               plugins=[
                   jwt_auth_plugin,
                   # redis_auth_plugin,
               ],
               error_response=JSONResponse,
               json_data_class=MyJsonResponseConfig,
     
           ),
   )
