我有一个 node.js 服务器，它提供一个带有密码文本输入的 index.html。 在检查服务器端密码后，应该开始为客户端下载。 客户端不应该能够看到文件在服务器上的位置路径。
这是我的 server.js:
var
http = require('http'),
qs = require('querystring'),
fs = require('fs') ;
console.log('server started');
var host = process.env.VCAP_APP_HOST || "127.0.0.1";
var port = process.env.VCAP_APP_PORT || 1337;
http.createServer(function (req, res) {
if(req.method=='GET') {
console.log ( ' login request from ' + req.connection.remoteAddress );
fs.readFile(__dirname +'/index.html', function(error, content) {
if (error) {
res.writeHead(500);
res.end();
}
else {
res.writeHead(200, { 'Content-Type': 'text/html' });
res.end(content, 'utf-8');
}
});
} // method GET end
else{ // method POST start
console.log('POST request from ' + req.connection.remoteAddress);
var body = '';
req.on('data', function (data) {
body += data;
if (body.length > 500) {
// FLOOD ATTACK OR FAULTY CLIENT, NUKE REQUEST
req.connection.destroy(); console.log('too much data')}
});
req.on('end', function () {
var postdata = qs.parse(body);
var password = postdata.passwordpost ;
if (password == '7777777') {
console.log('the password is right, download starting');
// ??????????????????????????????????? here I need help from stackoverflow
}
else{
console.log ('password wrong');
fs.readFile(__dirname +'/wrongpassword.html', function(error, content) {
if (error) {
res.writeHead(500);
res.end();
}
else {
res.writeHead(200, { 'Content-Type': 'text/html' });
res.end(content, 'utf-8');
}
});
}
}); // req on end function end
}
}).listen(port, host);
我需要帮助的部分标有????????
这是我的 index.html:
<html>
<body>
<br> <br>
please enter your password to start your download
<br> <br>
<form method="post" action="http://localhost:1337">
<input type="text" name="passwordpost" size="50"><br><br>
<input type="submit" value="download" />
</form>
</body>
</html>
你知道怎么做吗？
最佳答案
当然，您可以在代码中使用它:
res.setHeader('Content-disposition', 'attachment; filename='+filename);
//filename is the name which client will see. Don't put full path here.
res.setHeader('Content-type', 'application/x-msdownload'); //for exe file
res.setHeader('Content-type', 'application/x-rar-compressed'); //for rar file
var file = fs.createReadStream(filepath);
//replace filepath with path of file to send
file.pipe(res);
//send file
关于javascript - 如何将文件(exe 或 rar )提供给客户端以从 node.js 服务器下载？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16500615/
