reactjs - 从构造函数调用操作与生命周期方法

Question

哪里是调用 API 调用以补充我的状态的操作的最佳位置？构造函数或生命周期方法之一，例如组件将安装吗？

Answer 1

最好从生命周期方法 componentDidMount 进行 api 调用，react doc 也建议了同样的做法。

根据 DOC :

<强> componentDidMount:

componentDidMount() is invoked immediately after a component is mounted. Initialization that requires DOM nodes should go here. If you need to load data from a remote endpoint, this is a good place to instantiate the network request. Setting state in this method will trigger a re-rendering.
