问题描述

我试图制作一个简单的Python程序，该程序通过IB本机API连接到我的模拟帐户.但是，当我运行程序时，出现错误: IB AttributeError:'IBapi'对象没有属性'connState'

I tried to make a simple Python program, that connects via the IB native API to my Demo Account. But when I run the program it comes an error: IB AttributeError: 'IBapi' object has no attribute 'connState'

程序如下:

from ibapi.wrapper import EWrapper  

class IBapi(EWrapper, EClient):
     def init(self):
         EClient.init(self, self) 

app = IBapi()
app.connect('127.0.0.1', 7497, 123)
app.run()

推荐答案

在创建对象实例后自动调用的python初始化方法名为__init__，而不是init.

The python initialization method that is automatically called after an object instance has been created is named __init__, not init.

https://docs.python.org/3/reference/datamodel.html#object.初始化

在您的代码中，将永远不会调用init方法.应该是:

In your code the init method will never be called. It should be:

from ibapi.client import EClient 
from ibapi.wrapper import EWrapper


class IBapi(EWrapper, EClient):
    def __init__(self):         
        EClient.__init__(self, self)
