HttpClients.createSystem() 与 HttpClients.createDefault() 之间的区别？
Difference between HttpClients.createSystem() vs HttpClients.createDefault()?
我正在查看在 org.apache.http.impl.client.HttpClients 中创建 ClosableHttpClient 的方法，我看到了两种可能的方法：
.createDefault(): 使用默认配置创建 CloseableHttpClient 实例.createSystem(): 根据系统属性使用默认配置创建 CloseableHttpClient 实例。
两者有什么区别？我知道 it is possible to set up a custom client with .custom() to override certain behaviors 但是我剩下的问题是：
- 与
.createDefault() 关联的默认值是什么？
- 哪些系统属性会影响
.createSystem()？
- 是否可以修改使用
.createDefault() 或 .createDefault() 创建的未来客户端的行为？
由于历史原因（可追溯到 200 年代早期）HttpClient 默认不考虑系统属性。
What are the defaults associated with .createDefault()?
这些是 HttpClient 开发人员选择的项目默认值
What system properties affect .createSystem()?

Is it possible to modify the behavior of future clients that are created with .createDefault() or .createDefault()?
当然，通过HttpContext
