连接和连接请求超时 [英] Connection and connection request timeout

问题描述

我正在使用 Http Apache 组件来执行 http 交互.我需要调整我的 http 客户端.为此，我有两个参数:连接超时和连接请求超时.在库文档和源代码中(没有找到注释)，我没有找到这些术语的定义.我需要知道它们到底是什么意思.可能它们是在 HTTP 协议文档中定义的，但我找不到.所以，我的问题是这两个术语是什么意思以及它们之间的区别.

I am using Http Apache Components to perform the http interactions. I need to adjust my http client. For this purpose I have two parameters: connection timeout and connection request timeout. In library documentation and in source code(no comments were found) I didn't found definition of this terms. I need to know what do they exactly mean. May be they were defined in HTTP protocol documentation but I can't find it. So, my question is what do this two terms mean and how they distinct from each other.

推荐答案

HttpClient 有一种设置连接和套接字超时的方法(setConnectionTimeout() 和 setTimeout()) 根据 HttpClient javadocs.

HttpClient has a way to set connection and socket timeout (setConnectionTimeout() and setTimeout()) according to the HttpClient javadocs.

Connection timeout 是与服务器建立连接之前的超时时间.

Connection timeout is the timeout until a connection with the server is established.

Socket timeout 是接收数据的超时时间(socket timeout).

Socket timeout is the timeout to receive data (socket timeout).

示例:

假设您将浏览器指向一个网页.如果服务器在 X 秒内没有 anwser，将发生连接超时.但是如果它建立了连接，那么服务器将开始为浏览器处理结果.如果在Y秒内没有结束这个处理，就会发生socket超时.

Let's say you point your browser to access a web page. If the server does not anwser in X seconds, a connection timeout will occur. But if it establishes the connection, then the server will start to process the result for the browser. If it does not ends this processing in Y seconds, a socket timeout will occur.
