java - CoreConnectionPNames.SO_TIMEOUT 和 CoreConnectionPNames.CONNECTION_TIMEOUT 有什么区别？

Question

谁能解释一下这两个参数的区别？

1. > org.apache.http.params.CoreConnectionPNames.CONNECTION_TIMEOUT ;
2. > org.apache.http.params.CoreConnectionPNames.SO_TIMEOUT .

根据 javadocs:

CoreConnectionPNames.CONNECTION_TIMEOUT:

Determines the timeout in milliseconds until a connection is established. A timeout value of zero is interpreted as an infinite timeout.

CoreConnectionPNames.SO_TIMEOUT:

Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets).

那么，对于第一个，CoreConnectionPNames.CONNECTION_TIMEOUT，它是否发生在发送任何数据之前？对于第二个，CoreConnectionPNames.SO_TIMEOUT，是否意味着已经发送了一些数据？表示已成功建立连接。

谢谢。

Answer 1

does it happen before any data is sent?

是的，确实如此。

does it mean that some data was already sent?

在 HTTP 级别上，不，它没有。 (TCP/IP 或 SSL 可能是另一回事)

Meaning that connection was successfully established.

是的，确实如此。
