Plugins may register their own JSON-RPC methods that are exposed through the JSON-RPC provided by `lightningd`. This provides users with a single interface to interact with, while allowing the addition of custom methods without having to modify the daemon itself.
|
|
|
|
JSON-RPC methods are registered as part of the `getmanifest` result. Each registered method must provide a `name`. This information is then added to the internal dispatch table, and used to return the help text when using `lightning-cli help`, and the methods can be called using the `name`.
|
|
|
|
For example, `getmanifest` result will register two methods, called `hello` and `gettime`:
|
|
|
|
```json
|
|
...
|
|
"rpcmethods": [
|
|
{
|
|
"name": "hello",
|
|
"usage": "[name]"
|
|
},
|
|
{
|
|
"name": "gettime",
|
|
"usage": "",
|
|
}
|
|
],
|
|
...
|
|
```
|
|
|
|
|
|
|
|
The RPC call will be passed through unmodified, with the exception of the JSON-RPC call `id`, which is internally remapped to a unique integer instead, in order to avoid collisions. When passing the result back the `id` field is restored to its original value.
|
|
|
|
Note that if your `result` for an RPC call includes `"format-hint":
|
|
"simple"`, then `lightning-cli` will default to printing your output in "human-readable" flat form.
