GSYDefaultHttpDataSource (gsyVideoPlayer-exo2 7.1.5)

java.lang.Object
- BaseDataSource
- - tv.danmaku.ijk.media.exo2.source.GSYDefaultHttpDataSource

```
public class GSYDefaultHttpDataSource
extends BaseDataSource
```
An HttpDataSource that uses Android's HttpURLConnection.
By default this implementation will not follow cross-protocol redirects (i.e. redirects from HTTP to HTTPS or vice versa). Cross-protocol redirects can be enabled by using the GSYDefaultHttpDataSource(String, int, int, boolean, RequestProperties) constructor and passing true for the allowCrossProtocolRedirects argument.
Note: HTTP request headers will be set using all parameters passed via (in order of decreasing priority) the dataSpec, setRequestProperty(java.lang.String, java.lang.String) and the default parameters used to construct the instance.
