I want to uplaod an image with nodejs.
I send the file to node, but the follow question is that I don't know how to deal the "req".
Client
<html>
<body>
<input id="uploadInput" type="file"/>
<div id="uploadShow"></div>
<script type="text/javascript">
uploadInput = document.getElementById("uploadInput");
uploadInput.onchange = function() { //when file ready to upload
if(uploadInput.files && uploadInput.files[0]) {
var file = uploadInput.files[0]; //I want to send the file
var xhr = new XMLHttpRequest();
if (xhr.readyState == 4 && xhr.status == 200) {
var uploadShow = document.getElementById("uploadInput");
uploadShow.innerHTML = xhr.responseText; //show file
}
xhr.open('POST', "/upload", false);
xhr.send(file); //send file...
}
};
</script>
</body>
</html>
Server
var http = require('http'),url = require("url"),
path = require('path'),fs = require('fs');
http.createServer(function(req, res) {
var filename = "/index.html";
if (req.url !== "/") {
filename = url.parse(req.url, true).pathname;
filename = filename.split("?")[0];
}
if (filename === "/upload" && req.method.toLowerCase() == 'post') {
//deal the request of ajax
**upload_file**(req, res); //can you help me to write this function
return;
}
//the following fs.readFile index.html
}).listen("192.168.39.9", 8888);
How can I upload a image and show?
