How to use HttpClient with multithreaded operation?
提问by wangyin
I've to do an application that performs a Login POST request in a certain host, then navigates some pages, finds and retrieves some data. Becase the website resouce is protected by session, so I have to login the website first before I can do some operation such as get or post some data. My question is because HttpClient is not thread-safe, how can I create only one HttpClient instance but threads can perform on it safely? Remember that the underlying connection must login first before it can be used to operate.
我必须做一个在某个主机中执行登录 POST 请求的应用程序，然后导航一些页面，查找并检索一些数据。因为网站资源是受会话保护的，所以我必须先登录网站，然后才能进行一些操作，例如获取或发布一些数据。我的问题是因为 HttpClient 不是线程安全的，如何只创建一个 HttpClient 实例但线程可以安全地对其执行？请记住，底层连接必须先登录，然后才能使用它进行操作。

You can make HttpClient thread safe by specifying a thread safe client manager.
您可以通过指定线程安全客户端管理器来使 HttpClient 线程安全。
