Question

我是node.js的新手，并且一直在尝试设置一个基本的服务器。

我运行下面的代码，然后收到“Write After End”错误。

Socket.html是一个基本的html文件，在正文中有一个hello world字符串。该文件中没有其他内容。我已经尝试使用“ReadFileSync”方法，并引发了一组我不完全理解的新错误。

我将不胜感激任何帮助。我是全新的，所以请对我有点容易:)提前谢谢你！

我已经验证路径是正确的，并且缓冲区确实有数据。

var http = require('http');
var url = require('url');
var fs = require('fs');

var server = http.createServer(function(request, response){
console.log('Connection');

var path = url.parse(request.url).pathname.substr(1);
path = "\\" + path;

switch(path){
    case '/':
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.write('hello world');
        break;
    case '\\socket.html':
        //console.log(path);
        fs.readFile(__dirname + path, function(error, data){
            if(error){
                response.writeHead(404);
                response.write("This domain is missing");
            }
            else{
                console.log(data);
                response.writeHead(200, {"Content-Type": "text/html"});
                response.write(data,"utf8");
            }
        });
        break;
    default:
        response.writeHead(404);
        response.write("This domain is missing");
        break;
}

response.end();
});

server.listen（8001）;

我认为当您从FileSystem async中读取时，response.end()方法会在response.write()之前调用我建议使用以下代码：

var http = require('http'); 
var url = require('url'); 
var fs = require('fs'); 
var server = http.createServer(function(request, response) {
    var path = url.parse(request.url).pathname.substr(1);
    path = "\\" + path; 
    switch(path) {
        case '/':
            response.writeHead(200, {'Content-Type': 'text/html'}); 
            response.write('hello world'); 
            response.end();
        break; 
        case '\\socket.html':
            fs.readFile(__dirname + path, function(error, data) { 
                if(error) {
                    response.writeHead(404); 
                    response.write("This domain is missing"); 
                } else {
                    response.writeHead(200, {"Content-Type": "text/html"});
                    response.write(data, "utf8"); 
                } 
                response.end();
            }); 
        break; 
        default: 
            response.writeHead(404); 
            response.write("This domain is missing"); 
            response.end();
        break;
    } 
});
