in nodejs, you need to send structural data to the C process through socket, using
https://www.npmjs.com/package.
but when sending an error, only Buffer: is recognized
.var net = require("net");
var ref = require("ref")
var StructType = require("ref-struct")
var MyDataHead = StructType({
type: ref.types.uint,
len: ref.types.uint,
state: ref.types.int
})
var head = new MyDataHead
head.type = 1
head.len = 0
head.state = 0
var sockfile = "/var/run/xxx.sock"
var client = net.connect({path: sockfile}, function() {
//"connect" listener
console.log("connected to server!");
client.write(head);
});
client.on("data", function(data) {
console.log(data.toString());
client.end();
});
client.on("end", function() {
console.log("disconnected from server");
});TypeError: Invalid data, chunk must be a string or buffer, not object
