A plug that responds to POSTed JSON-RPC 2.0 in the request body.

If you wish to start a standalone server which will respond to JSON-RPC 2.0 POSTs at any URL, please see JSONRPC2.Servers.HTTP.

If you wish to mount a JSON-RPC 2.0 handler in an existing Plug-based web application (such as Phoenix), you can do so by putting this in your router:

forward "/jsonrpc", JSONRPC2.Servers.HTTP.Plug, YourJSONRPC2HandlerModule

The above code will mount the handler YourJSONRPC2HandlerModule at the path "/jsonrpc".

The Plug.Parsers module for JSON is automatically included in the pipeline, and will use the same serializer as is defined in the :serializer key of the :jsonrpc2 application. You can override the default options (which are used in this example) like so:

forward "/jsonrpc", JSONRPC2.Servers.HTTP.Plug, [
  handler: YourJSONRPC2HandlerModule,
  plug_parsers_opts: [
    parsers: [:json],
    pass: ["*/*"],
    json_decoder: Application.get_env(:jsonrpc2, :serializer)
  ]
]
