jsonrpc
The jsonrpc middleware provides JSON-RPC 2.0 support. Below is an example exposing the add and sub methods:
var math = {
add: function(a, b, fn){
fn(null, a + b);
},
sub: function(a, b, fn){
fn(null, a - b);
}
};
var date = {
time: function(fn){
fn(null, new Date().toUTCString());
}
};
connect.createServer(
connect.jsonrpc(math, date)
);
When you wish to pass an exception simply invoke fn(err)
, or pass the error code fn(jsonrpc.INVALID_PARAMS)
. Otherwise fn(null, result)
will respond with the given results.
