I am trying to create an HTTP server that the user can upload images and archives, and for that I am using formidable for handling the upload part.
My code :
requestHandler.js
// Request Handlers (will handle all requests that happen)
// Allows Node.js to make use of a non-blocking operation: exec ();
var exec = require("child_process").exec;
var querystring = require("querystring");
fs = require("fs");
var fomidable = require("formidable");
function start(response, postData) {
console.log("Request handler 'start' was called");
var body = '<html>' +
'<head>' +
'<meta http-equiv = "Content-Type" content = "text/html";'+
'charset="UTF-8"/>' +
'</head>' +
'<body>' +
'<form action = "/upload" enctype = "multipart/form-data"' +
'method = "post">' +
'<input type ="file" name = "upload multiple = "multiple">' +
'<input type = "submit" value ="Upload file" />' +
'</form>' +
'</body>' +
'</html>';
response.writeHead(200, {"Content-Type" : "text/html"});
response.write(body);
response.end();
}
// What is being passed between router.js and requestHandler.js is the entire body of the POST data request.
function upload(response, request) {
console.log("Request handler 'upload' was called");
var form = new formidable.IncomingForm();
console.log("about to parse");
form.parse(request, function(error, fields, files) {
console.log("parsing done");
/*Possible error on Windows systems; tried to rename to an already existing file*/
fs.rename(files.upload.path, "/tmp/test.png", function(err) {
if(err) {
fs.unlink("/tmp/test.png");
fs.rename(files.upload.path, "/tmp/test.png");
}
});
response.writeHead(200, {"Content-Type" : "text/plain"});
response.write("You've sent the text : " + querystring.parse(postData).text);
response.write("\nHello Upload");
response.end();
});
}
function show(response) {
console.log("Request handler 'show' was called.");
fs.readFile("/tmp/test.png", "binary", function(error,file) {
if(error) {
response.writeHead(500, {"Content-Type" : "text/plain"});
response.write(err + "\n");
response.end();
} else {
response.writeHead(200, {"Content-Type" : "image/png"});
response.write(file, "binary");
reponse.end();
}
});
}
exports.start = start;
exports.upload = upload;
exports.show = show;
I am using too formidable in the another part of my code, in my server.js but there for some reason works (And for that reason I am not posting the code), the error point out to requestHandler.js in line 35 :
var form = new formidable.IncomingForm();
formidable is not defined
How can I make formidable defined ? When I am already doing that calling in the first place in :
var formidable = require("formidable");
