我正在使用socket.io框架从我自定义的IoT设备获取数据。设备使用TCP / IP协议,我的网站使用HTTP协议。所以,沟通没有问题,但我在网页上看不到任何CSS样式。
我有很多css文件和css文件目的地。
这是我的server.js代码:
render(){
return(
<Card>
<CardSection>
<Input
borderColor="transparent" //props for border
label="Email"
placeHolder="abc@example.com"
onChangeText={this.onEmailChanged.bind(this)}
value={this.props.email}
/>
</CardSection>
<CardSection>
<Input
borderColor="transparent" // props for border
secureTextEntry
label="Password"
placeHolder="password"
onChangeText={this.onPasswordChanged.bind(this)}
value={this.props.password}
/>
</CardSection>
{this.errorRender()}
<CardSection>
{this.spinerRender()}
</CardSection>
</Card>
);
}
这是我的index.html;
// socket io
var app = require('http').createServer(handler),
io = require('socket.io').listen(app),
fs = require('fs'),
express = require('express'),
exp = express();
exp.use('*/css',express.static('css'));
app.listen(80, function() {
console.log('Socket IO Server is listening on port 80');
});
function handler(req, res) {
fs.readFile(__dirname + '/index.html', function(err, data) {
if(err) {
res.writeHead(500);
return res.end('Error');
}
res.writeHead(200);
res.write(data);
res.end();
})
};
io.on('connection', function(socket) {
console.log('connection...');
socket.on('emit_from_client', function(data) {
console.log('socket.io server received : '+data);
io.emit('emit_from_client', data);
});
});
// TCP server
var net = require('net');
var writable = require('fs').createWriteStream('test.txt');
net.createServer(function (socket) {
console.log('socket connected');
socket.on('data', function(data) {
var line = data.toString();
console.log('got "data"', line);
socket.pipe(writable);
io.emit('emit_from_client', line); // socket.io
//socket.emit("OK\r\n"); // socket.io
socket.write("OK1\r\n");
});
socket.on('end', function() {
console.log('end');
});
socket.on('close', function() {
console.log('close');
});
socket.on('error', function(e) {
console.log('error ', e);
});
socket.write('Hello from tcp server\r\n');
}).listen(3080, function() {
console.log('TCP Server is listening on port 3080');
});
答案 0 :(得分:0)
确保您的资产为statically available:
app.use(express.static('css'))
由于您的资产无法以这种方式访问,因此输出中的内容并未反映
stated作为@ArpitSolanki,请尝试:
exp.use('/css/*',express.static('css'));
另外,根据您的代码:
exp.use('*/css',express.static('css'));
我从未见过这样的道路。
