Using java NIO(netty),fast down and easy to customize.
To create a download task, need to construct a request and a config.
Build a HTTP request.
The default method is GET,We can also use POST,PUT...
The default request header refers to the following table.
| key | value |
|---|---|
| Host | {host} |
| Connection | keep-alive |
| User-Agent | Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.75 Safari/537.36 |
| Accept | text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8 |
| Referer | {host} |
We can customize the request header,when overriding the default value, the default request header will be replaced.
{host}:is Domain name parsed from url
Set the request body,only support text format.
Default will request once for response related information,such as support HTTP 206,Content-Length,attach name.
If know response Content-Length and name,can create a task directly, without spending a request to resolve the task name and size.
