我不知道为什么您的代码当时失败了。可以像这样捕获 400 响应（例如abort call）：
def abort(self):
try:
self.client.bots.abort_game(self.game_id)
return True
except requests.exceptions.HTTPError as herr:
if self.debug:
print (herr)
return False
请在下面找到一个稍微修改过的版本，它适用于Play-Chess-With-A-WebCam（我是提交者）的上下文中。您需要在 ~/.pcwawc/config.yaml 中有一个带有令牌的 config.yaml 文件：
# Play Chess With a Webcam configuration file
# WF 2019-12-21
token: YOUR_TOKEN_HERE
测试结果是：
gameStart {'type': 'gameStart', 'game': {'id': '20XfiEMn'}}
The game 20XfiEMn has started!
