JavaScript中发出HTTP请求最常用的方法

阅读更多关于 JavaScript中发出HTTP请求最常用的方法

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> JavaScript具有很好的模块和方法来发送可用于从服务器端资源发送或接收数据的HTTP请求。在本文中，我们将介绍一些在JavaScript中发出HTTP请求的流行方法。 Ajax Ajax是发出异步HTTP请求的传统方式。可以使用HTTP POST方法发送数据，并使用HTTP GET方法接收数据。我们来看看发送GET请求。我将使用JSONPlaceholder，这是一个免费的在线REST API，适用于以JSON格式返回随机数据的开发人员。要在Ajax中进行HTTP调用，您需要初始化一个新XMLHttpRequest()方法，指定URL端点和HTTP方法（在本例中为GET）。最后，我们使用该open()方法将HTTP方法和URL端点绑定在一起，并调用该send()方法来触发请求。我们使用XMLHTTPRequest.onreadystatechange包含要在readystatechanged事件触发时调用的事件处理程序的属性将HTTP响应记录到控制台。如果您查看浏览器控制台，它将返回JSON格式的数据数组。但是我们怎么知道请求是否完成了？换句话说，我们如何使用Ajax处理响应？该onreadystatechange有两个方法，readyState 和 status允许我们可以检查请求的状态。
