Project - API Money - recive current costs of Rubl

About the project.

This application is a Fast Api server with the ability to provide the exchange rate of coins on any date. The main idea:

1. FAST API Server.
   

• use API of https://cbr.ru/development/SXML/ to get new information about exchange rate of coins.
  
• Check information in database - Mongo DB.
  
• Save new information on Mongo Db database.
  

you can make a request http://127.0.0.1:8000/coin/GBP where GBP - is a coin of England

2. Vue JS.
   

• the user can write the name of coin and get information from our Fast Api Server.
  
  

3. Ready Dockerfile and Docker-compose.yml to RUN Containers.
   Just type the command: docker-compose up Container for app + Container for MongoDB
   
   

Interesting points about API of SBR:

• All information from https://cbr.ru/development/SXML/ we recive not in JSON but as XML so we need to use - import xmltodict as xmltodict
  

Intresting points about Mongo db to JSON:

• When we try to pass Mongo Db information as JSON response in Fast API we can recieve problem with '_ id' because it is not just field like int or str, so Fast Api can't serialize this field, the opcion is not use this field, just skip it like:
  find_item = collection_name.find_one({'date': f'{date}'}, {'_id': 0}).

RESOLVED Problem. When we try make a API request from Vue JS to localhost Fast Api you can get this error:

• fast api from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin'
  
  

You can do:

from fastapi.middleware.cors import CORSMiddleware

and add:

origins = ["*"]

app.add_middleware(
CORSMiddleware,
allow_origins=origins,
allow_credentials=True,
allow_methods=[""],
allow_headers=[""],
)
