从网络服务器接收数据

Question

我在实现简单 Web 服务器的程序中遇到问题。

当我向网络服务器发送 HTTP 请求时，网络服务器向客户端发送 HTTP 代码，但我想接收 => 我有错误“连接已重置！）

clientSocket = new Socket("localhost", 1234);

BufferedWriter out = new BufferedWriter(
        new OutputStreamWriter(
                new BufferedOutputStream(clientSocket.getOutputStream()), "UTF-8")
);
out.write(OUTPUT_HEADERS+"GET /"+"home.html" + " HTTP/1.1\nHost:"+clientSocket.getLocalAddress() +"\nUser-agent: Mozilla/5.0\nAccept-language: fa");
out.flush();

System.out.println(" waiting...");

InputStreamReader isr=new InputStreamReader(clientSocket.getInputStream());
BufferedReader br=new BufferedReader(isr);
while (br.ready()) {                
    System.out.println(br.readLine());
}

Answer 1

根据 HTTP 1.1 规范：

http://www.w3.org/Protocols/HTTP/1.1/rfc2616bis/draft-lafon-rfc2616bis-03.html#request

请求和请求头需要用 CR/LF 终止。

即变化：

out.write(OUTPUT_HEADERS+"GET /"+"home.html" + " HTTP/1.1\nHost:"+clientSocket.getLocalAddress() +"\nUser-agent: Mozilla/5.0\nAccept-language: fa");
out.flush();

到

out.write(OUTPUT_HEADERS+"GET /"+"home.html" + " HTTP/1.1\r\nHost:"+clientSocket.getLocalAddress() +"\r\nUser-agent: Mozilla/5.0\r\nAccept-language: fa\r\n");
out.write("\r\n");
out.flush();
