我想用nodejs上傳圖片。如何使用nodejs上傳文件
我發送文件到節點，但接下來的問題是，我不知道如何處理「請求」。

<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>

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);
我如何上傳圖像和顯示？
'文件[0]'可能並沒有真正給你的文件，更像是高度，寬度的對象，以及URL''fakepath/image.png''或者什麼的，那只是一個字符串。該圖像將位於formData對象中。 – adeneo
