Getting node.js to read files in html format
提问by Saif Bechan
I am developing a small app in Node.js. I am just using Node.js for input and output. The actual website is just running through nginx. The website has a Websocket connection with node.js and is primarily used for db manipulations.
我正在 Node.js 中开发一个小应用程序。我只是使用 Node.js 进行输入和输出。实际的网站只是通过 nginx 运行。该网站与 node.js 有 Websocket 连接，主要用于数据库操作。
One of the things I am trying to do is get node to send small pieces of html along with the data from the database. I tried the following code.
我正在尝试做的一件事是让节点发送小块 html 以及来自数据库的数据。我尝试了以下代码。
simplified:
简化：
connection.on('message', function(message) {
fs.readFile(__dirname + '/views/user.html', function(err, html){
if(err){
console.log(err);
}else{
connection.sendUTF( JSON.stringify({
content: html,
data: {}
}));
}
});
}
});
When I console.log(html)on the server or in the client I only get numbers back.
当我console.log(html)在服务器或客户端时，我只会得到数字。
Anyone know what could be wrong.
任何人都知道可能有什么问题。
NOTE:I really want to stay away from stuff like socket.io, express, etc. Just keeping it as simple as possible and no fallbacks are needed.
注意：我真的很想远离诸如socket.io,express等之类的东西。只要让它尽可能简单并且不需要回退。

If you don't specify an encoding for fs.readFile, you will retrieve the raw buffer instead of the expected file contents.
如果您没有为fs.readFile指定编码，您将检索原始缓冲区而不是预期的文件内容。
Try calling it this way:
尝试这样称呼它：
fs.readFile(__dirname + '/views/user.html', 'utf8', function(err, html){
....
