通过socket.io发送匿名函数？

JSON不支持包含

function

相反，您可以做的是

commands

function

commandName

// client-sidevar commands = {    log: function (param) {        console.log(param);    }};socket.on('executecommand', function(data){    var a = 'foo';    commands[data.commandName](a);});// server-sidesocket.emit('executecommand', { commandName: 'log' });

您还可以使用

fn.apply()

commandName

in

// client-sidevar commands = {  };socket.on('executecommand', function(data){    if (data.commandName in commands) {        commands[data.commandName].apply(null, data.arguments || []);    } else {        console.error('Unrecognized command', data.commandName);    }});// server-sidesocket.emit('executecommand', {    commandName: 'log',    arguments: [ 'foo' ]});
