我该如何解决这个问题。非常感谢你花时间去看。我不知道还有什么可以做几个小时就谢谢了。我从这里下载代码，并试图运行它几个小时。得到了来自betfair的api，它仍然无法正常工作。 https://github.com/cribbinm/Betting-Arbitrage

在这里，您要将login_data设置为urllib.urlparse.urlencode的输出，这是一个字符串。但urllib.request.Request期望字节为data参数。
解决方案是编码login_data UTF-8通常是合理的值。
def getSESSIONToken(username, password):
login_data = urllib.parse.urlencode({
'username' : username,
'password' : password,
'product' : 'exchange',
'url' : 'https://www.betfair.com/Fexchange/login/success/rurl/https://www.betfair.com/Fexchange'
})
url = "https://identitysso.betfair.com/api/login"
req = urllib.request.Request(url, login_data.encode('utf-8'))
