[英]Java Building a Basic WebServer how do i send headers to browser
问题描述
I'm still learning java and trying to build a basic WebServer using Sockets for now i have the server working and sending output data back to the browser but i'm unsure how to send the headers i thought they were just "\\r\\n\\r\\n" from the content body 
我还在学习java并尝试使用套接字构建一个基本的WebServer现在我让服务器工作并将输出数据发送回浏览器但是我不确定如何发送标题我认为它们只是“\\ r \\ n \\ r \\ n“来自内容正文
This is how i'm writing to the browser currently 这就是我当前正在写入浏览器的方式
Socket socket = socketServer.accept();
System.out.println("Web Request From: "+socket.getInetAddress().toString());
BufferedReader in = new BufferedReader(
new InputStreamReader(socket.getInputStream())
);
PrintWriter out = new PrintWriter(socket.getOutputStream());
Stirng output = "<!DOCTYPE html><html><body><h1>403 Forbidden</h1></body></html>"
out.write(output, 0, output.lenght());
out.flush();
out.close();

Put the headers in the output string, separated from each other by \\r\\n and from the main body by \\r\\n\\r\\n . 放头在输出串，由彼此分离\\r\\n和从主体由\\r\\n\\r\\n 。 Or, with the PrintWriter just print them one by one, an empty line, and then the body. 或者，PrintWriter只需逐个打印，空行，然后是正文。

your forced to send the HTTP information first 你被迫首先发送HTTP信息
out.println("HTTP/1.0 200");
is required before any other codes send or the main body 在任何其他代码发送或主体之前需要
