goupnp is a UPnP client library for Go
## Installation
2019-06-09 07:24:20 +00:00
Run `go get -u github.com/huin/goupnp`.
## Documentation
See [GUIDE.md](GUIDE.md) for a quick start on the most common use case for this
library.

Supported DCPs (you probably want to start with one of these):
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) av1](https://godoc.org/github.com/huin/goupnp/dcps/av1) - Client for UPnP Device Control Protocol MediaServer v1 and MediaRenderer v1.
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) internetgateway1](https://godoc.org/github.com/huin/goupnp/dcps/internetgateway1) - Client for UPnP Device Control Protocol Internet Gateway Device v1.
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) internetgateway2](https://godoc.org/github.com/huin/goupnp/dcps/internetgateway2) - Client for UPnP Device Control Protocol Internet Gateway Device v2.

Core components:
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) (goupnp)](https://godoc.org/github.com/huin/goupnp) core library - contains datastructures and utilities typically used by the implemented DCPs.
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) httpu](https://godoc.org/github.com/huin/goupnp/httpu) HTTPU implementation, underlies SSDP.
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) ssdp](https://godoc.org/github.com/huin/goupnp/ssdp) SSDP client implementation (simple service discovery protocol) - used to discover UPnP services on a network.
- [![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg) soap](https://godoc.org/github.com/huin/goupnp/soap) SOAP client implementation (simple object access protocol) - used to communicate with discovered services.

## Regenerating dcps generated source code:
2019-06-09 07:24:20 +00:00
1. Build code generator:
`go get -u github.com/huin/goupnp/cmd/goupnpdcpgen`
2019-06-09 07:24:20 +00:00
2. Regenerate the code:
`go generate ./...`
2019-06-09 07:24:20 +00:00
## Supporting additional UPnP devices and services:
2019-06-09 07:24:20 +00:00
Supporting additional services is, in the trivial case, simply a matter of
adding the service to the `dcpMetadata` whitelist in `cmd/goupnpdcpgen/metadata.go`,
regenerating the source code (see above), and committing that source code.
However, it would be helpful if anyone needing such a service could test the
service against the service they have, and then reporting any trouble
encountered as an [issue on this
project](https://github.com/huin/goupnp/issues/new). If it just works, then
please report at least minimal working functionality as an issue, and
optionally contribute the metadata upstream.

## Migrating due to Breaking Changes
- \#40 introduced a breaking change to handling non-utf8 encodings, but removes a heavy
dependency on `golang.org/x/net` with charset encodings. If this breaks your usage of this
library, you can return to the old behavior by modifying the exported variable and importing
the package yourself:
```go
import (
"golang.org/x/net/html/charset"
"github.com/huin/goupnp"
)
func init() {
// should be modified before goupnp libraries are in use.
goupnp.CharsetReaderFault = charset.NewReaderLabel
}
```

## `v2alpha`
The `v2alpha` subdirectory contains experimental work on a version 2 API. The plan is to eventually
create a `v2` subdirectory with a stable version of the version 2 API. The v1 API will stay where
it currently is.
> NOTE:
>
> * `v2alpha` will be deleted one day, so don't rely on it always existing.
> * `v2alpha` will have API breaking changes, even with itself.
