### How can I make an AJAX call? {#how-can-i-make-an-ajax-call}
### 如何在 React 中发起 AJAX 请求?{#how-can-i-make-an-ajax-call}

You can use any AJAX library you like with React. Some popular ones are [Axios](https://github.com/axios/axios), [jQuery AJAX](https://api.jquery.com/jQuery.ajax/), and the browser built-in [window.fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API).
在 React 开发中,你能使用任何你喜欢的 AJAX 库,比如社区比较流行的 [Axios](https://github.com/axios/axios)[jQuery AJAX](https://api.jquery.com/jQuery.ajax/),或者是浏览器内置的 [window.fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API)

### Where in the component lifecycle should I make an AJAX call? {#where-in-the-component-lifecycle-should-i-make-an-ajax-call}
### 应该在 React 组件的哪个生命周期函数中发起 AJAX 请求?{#where-in-the-component-lifecycle-should-i-make-an-ajax-call}

You should populate data with AJAX calls in the [`componentDidMount`](/docs/react-component.html#mounting) lifecycle method. This is so you can use `setState` to update your component when the data is retrieved.
我们推荐你在 [`componentDidMount`](/docs/react-component.html#mounting) 这个生命周期函数中发起 AJAX 请求。这样做你可以拿到 AJAX 请求返回的数据并通过 `setState` 来更新组件。

### Example: Using AJAX results to set local state {#example-using-ajax-results-to-set-local-state}
### 示例:使用 AJAX 请求结果去改变组件内部 state {#example-using-ajax-results-to-set-local-state}

The component below demonstrates how to make an AJAX call in `componentDidMount` to populate local component state.
下面这个组件演示了如何在 `componentDidMount` 中发起 AJAX 请求去更新组件的 state

The example API returns a JSON object like this:
示例 API 返回如下的 JSON 对象:
