只要创建一个空图片。
js代码:
var data = "http://localhost:8080/test?id="+id+"&content="+encodeURIComponent(content); //序列化表单数据
new Image().src=data;
后端返回一个空图片(后端采用mina框架),核心代码如下:
在MessageHandler的实现类中,
Class MyMessageHandler implements MessageHandler{
public void handle(IoSession session, Message message) {
..........................
response.setStatus(200);
response.setStatusText("OK"); response.setHeaders(new String[]{ "Server: AsmeServer", "Pragma: No-cache", "Cache-Control: no-cache", "Expires: Thu, 01 Jan 1970 00:00:00 GMT", "P3P: CP='IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT'", "Set-Cookie: opt=" + (inout ? "0" : "1") + COOKIE_ATTR, "Content-Type: image/gif", "Content-Length: 43", "Connection: close" }); response.setContent(CookieUtils.IMG11); session.write(response).addListener(IoFutureListener.CLOSE);...............................
}
}
