本文整理了Java中org.jsoup.Connection类的一些代码示例，展示了Connection类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Connection类的具体详情如下：
包路径：org.jsoup.Connection
类名称：Connection

Connection介绍

[英]A Connection provides a convenient interface to fetch content from the web, and parse them into Documents.

To get a new Connection, use org.jsoup.Jsoup#connect(String). Connections contain Connection.Requestand Connection.Response objects. The request objects are reusable as prototype requests.

Request configuration can be made using either the shortcut methods in Connection (e.g. #userAgent(String)), or by methods in the Connection.Request object directly. All request configuration must be made before the request is executed.
[中]连接提供了一个方便的接口，用于从web获取内容并将其解析为文档。
要获得新连接，请使用org。jsoup。Jsoup#connect（字符串）。连接包含连接。请求和连接。响应对象。请求对象可以作为原型请求重用。
可以使用连接中的快捷方式方法（例如#userAgent（String））或连接中的方法进行请求配置。直接请求对象。在执行请求之前，必须进行所有请求配置。
