python - 使用 python 请求从 oanda V20 Rest api 流式定价

Question

我正在尝试stream the price来自 Oandas V20 Rest api 的仪器，但没有取得太大成功。我正在使用 python requests，因为它适用于常规 get 请求。这是我必须要做的:

import requests
url = 'https://stream-fxpractice.oanda.com/v3/accounts/MY_ACCOUNT_ID/pricing?instruments=EUR_USD'
head = {'Content-type':"application/json",
        'Accept-Datetime-Format':"RFC3339",
        'Authorization':"Bearer MY_ACCESS8TOKEN"}


r = requests.get(url, headers=head, stream=True)
print(r)

for line in r.iter_lines():

    if line:
        decoded_line = line.decode('utf-8')
        print(json.loads(decoded_line))

响应错误代码为 405，表示不支持该方法。我做错了什么？

您的网址无效(请参阅 developer.oanda.com/rest-live-v20/pricing-ep/ )，
它应该是:

url_OK = 'https://stream-fxpractice.oanda.com/v3/accounts/MY_ACCOUNT_ID/pricing/stream?instruments=EUR_USD'

而不是:

urlNOT = 'https://stream-fxpractice.oanda.com/v3/accounts/MY_ACCOUNT_ID/pricing?instruments=EUR_USD'
//        |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||vvvvvvvv
// _OK = 'https://stream-fxpractice.oanda.com/v3/accounts/MY_ACCOUNT_ID/pricing/stream?instruments=EUR_USD'

如果您不想构造 URL 的麻烦，您可以使用 V20 绑定(bind)之一: https://github.com/search?utf8=%E2%9C%93&q=v20&type=
