Isticmaalka fadhi Requests oo proxy-ka yaqaan iyo pandas-datareader

pandas-datareader wuxuu aqbalaa fadhi Requests shaqadiisa HTTP. Tusaale ahaan, akhriyaha FRED wuxuu isticmaali karaa fadhi uu codsigu diyaariyay:

import requests
from pandas_datareader import data as web

with requests.Session() as session:
    session.proxies.update({
        "http": "http://proxy.example.net:8080",
        "https": "http://proxy.example.net:8080",
    })
    frame = web.DataReader(
        "GDP", "fred", start, end, session=session
    )

start iyo end waa taariikhaha codsigu weydiistay. Macnaha guud wuxuu xiraa fadhiga marka akhriyahu dhammeeyo. Qodob HTTP dadweyne oo laga doortay liiska proxy-yada HTTP ayaa bixin kara cinwaanka khariidadda proxy ee fadhigan.

Isku xirka Requests iyo deegaanka wuu shaqaynayaa tusaalahan. Haddii codsigu u baahan yahay waddo cad oo ka madax bannaan qiimayaasha proxy ee deegaanka, dhig session.trust_env=False oo si gooni ah u bixi xirmada CA loo baahan yahay ama aqoonsiga laga helay .netrc.

Dooro akhriye ay taageerto nooca pandas-datareader ee rakiban. API bixiye la joojiyay ama qaab sumad la beddelay ayaa ku guuldarraysan kara ka dib marka xiriirka proxy-ga guulaysto; dhigista fadhiga ma soo celiso qodob xog oo la tirtiray.
