问题描述：在响应中添加cookie的过程中出现以下异常

java.lang.IllegalArgumentException: An invalid character [32] was present in the Cookie value
    	org.apache.tomcat.util.http.Rfc6265CookieProcessor.validateCookieValue(Rfc6265CookieProcessor.java:182)
    	org.apache.tomcat.util.http.Rfc6265CookieProcessor.generateHeader(Rfc6265CookieProcessor.java:115)
    	org.apache.catalina.connector.Response.generateCookieString(Response.java:1010)
    	org.apache.catalina.connector.Response.addCookie(Response.java:962)
    	org.apache.catalina.connector.ResponseFacade.addCookie(ResponseFacade.java:385)
    	org.apache.jsp.deal_jsp._jspService(deal_jsp.java:126)
    	org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
    	javax.servlet.http.HttpServlet.service(HttpServlet.java:741)
    	org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:443)
    	org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:385)
    	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:329)
    	javax.servlet.http.HttpServlet.service(HttpServlet.java:741)
    	org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53)

代码如下所示：

Cookie cookie1 = new Cookie("username", m.replaceAll("").trim());
    cookie1.setPath("/");
    cookie1.setMaxAge(60 * 60 * 3);
    resp.addCookie(cookie1);
    req.getRequestDispatcher("/loginsuccess.jsp").forward(req, resp);

由于我是在尝试sql注入，所以输入的内容包含特殊字符，我以为是特殊字符惹的祸，然后我就用正则去除了特殊字符，但是依然报这个错误，在网上查找资料的过程中看到说是空格的影响，所以去除了空格。

Cookie cookie1 = new Cookie("username", m.replaceAll("").replace(" ",""));
    cookie1.setPath("/");
    cookie1.setMaxAge(60 * 60 * 3);
    resp.addCookie(cookie1);
    req.getRequestDispatcher("/loginsuccess.jsp").forward(req, resp);

然后，就没有报错啦~
