3. HttpServletResponse实现

BinCatResponse.java示例代码片段:

package com.anbai.sec.server.servlet;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletResponse;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.URLEncoder;
import java.util.*;
public class BinCatResponse implements HttpServletResponse {
  private final Socket socket;
  private final Map<String, String> header;
  private final ByteArrayOutputStream out;
  private int status = 404;
  private String statusMessage = "Not Found";
  private String charset = "UTF-8";
  private int contentLength = 0;
  private String contentType = "text/html; charset=UTF-8";
  private String location;
  public BinCatResponse(Socket socket, Map<String, String> header, ByteArrayOutputStream out) {
    this.socket = socket;
    this.header = header;
    this.out = out;
  }
  // 此处省略HttpServletResponse接口中的大部分方法，仅保留几个示例方法...
  public void setHeader(String name, String value) {
    this.header.put(name, value);
  }
  public String getHeader(String name) {
    return header.get(name);
  }
  public PrintWriter getWriter() throws IOException {
    return new PrintWriter(out);
  }
}
