python3.x - Python menyambung api dagangan simulasi oanda untuk mendapatkan soalan json soalan ke-5

Question

Kadangkala ia tiba-tiba berhenti berfungsi selepas bekerja seperti biasa selama lebih daripada sejam tanpa sebarang ralat, atau ralat requests.packages.urllib3.exceptions.ProtocolError: ('Sambungan dibatalkan.', BadStatusLine("''",)) dilaporkan di tempat lain di Internet ada yang mengatakan ia telah tamat masa, ada yang mengatakan ia disambungkan ke https, ada yang mengatakan ia perlu ditukar kepada python3.5 ke atas (saya menggunakan python3.4)

Program ini ialah atur cara asal dalam soalan sebelumnya ditambah gelung sementara Benar:, terima kasih

Program:

import requests
import json

url = "https://api-fxpractice.oanda.com/v1/prices"

instruments = 'EUR_USD,USD_CAD'
account_id = 'cawa11'
params = {'instruments':instruments,'accountId':account_id}

access_token = 'a554db3a48ac8180a6996a5547ba1663-ac5947e64456cc5842a34f4ce05e4380' 
headers = {'Connection': 'Keep-Alive',
           'Accept-Encoding': 'gzip,deflate',
           'Authorization':'Bearer '+access_token}    #Bearer后有空格

while True :
    r = requests.get(url,headers = headers, params=params) 
    price = r.json()
    print(r.json())
    print(price['prices'][0]['instrument'].replace('_','/'),':',round((price['prices'][0]['ask']+price['prices'][0]['bid'])/2,4),'  ',price['prices'][0]['time'])
    print(price['prices'][1]['instrument'].replace('_','/'),':',round((price['prices'][1]['ask']+price['prices'][1]['bid'])/2,4),'  ',price['prices'][1]['time'])

Answer 1

Ingkapsulkan kod kunci ke dalam fungsi dan tambah pengendalian ralat untuk memastikan bahawa walaupun benar tidak terganggu, dan pada masa yang sama mencetak maklumat untuk penyelesaian masalah

# coding: utf-8

    try:
        url = "https://api-fxpractice.oanda.com/v1/prices"

        params = {'instruments':instruments,'accountId':account_id}
