从Http Servlet请求标头读取浏览器/客户端时间 [英] Read Browser/Client time from Http Servlet request header

问题描述

是否可以在向servlet发出请求时读取浏览器（客户端计算机）时间？

Is it possible to read the Browser(Client machine) time when a request is made to the servlet?

推荐答案

I不要相信。遗憾的是，HTTP 日期标题仅发送给PUT或POST消息，即使这样它也是可选的：

I don't believe so. Unfortunately the HTTP Date header is only sent for PUT or POST messages, and even then it's optional:

客户端应该只在包含$ b的消息中发送Date头
字段$ b entity-body，如PUT
和POST请求的情况，即使这样，它也是
可选。没有时钟的客户
绝不能在
请求中发送Date头字段。

Clients SHOULD only send a Date header field in messages that include an entity-body, as in the case of the PUT and POST requests, and even then it is optional. A client without a clock MUST NOT send a Date header field in a request.

如果你有控制客户端，您可以（可能）将其编码为单独的实验性HTTP标头。或者将其添加为GET参数等。

If you have control of the client, you could (perhaps) encode it as a separate experimental HTTP header. Or add it as a GET parameter etc.
