javascript - TS2322：类型'{准备好：假；会话：空；}' 不可分配给类型 'Readonly '

Answer 1

问题是状态可能有其他属性，您无法初始化这些属性，因为您在 HOC 中不知道它们。考虑以下：

class MyComponent extends RX.Component<withAuthProps, withAuthState & { myStateProp: number }>{}    
const MyComponentWithAuth = withAuth(MyComponent);
let comp = new MyComponentWithAuth({});
// myStateProp does not exist on state because you did not initialize it in your HOC even though the property is required
comp.state.myStateProp 

如果你对这种行为没问题，你可以在初始化状态时使用类型断言：

this.state = {
    ready: false,
    session: null
} as S & withAuthState;
