Apache HTTPClienthas equivalent functionality, though the APIs are not exactly the same. Oakland Software has a tablecomparing their commercial product with various alternatives, including the Apache product. Apache's own opinion of the built-in HttpUrlConnection (quoted from the above linked-to page) is:
Apache HTTPClient具有等效的功能，但 API 并不完全相同。Oakland Software 有一张表格，将他们的商业产品与各种替代品（包括 Apache 产品）进行了比较。Apache 自己对内置 HttpUrlConnection（引自上述链接页面）的看法是：
The jdk has the HttpUrlConnection which is limited and in many ways flawed.
jdk 的 HttpUrlConnection 是有限的，并且在很多方面都有缺陷。
Here's a link to the HTTPClient tutorial.
这是 HTTPClient教程的链接。
