一、代碼

調(diào)用方：ajax發(fā)送post請求，帶請求體

$.ajax({
????type:?"post",
????url:?base?+?"/postJson",
????contentType:?"application/json;charset=utf-8",
????data:?JSON.stringify({name:?"Hemingway"}),
????success:?function?(json)?{
????????result?=?json;
????}
});

被調(diào)用方：在簡單 get 請求過濾器配置的基礎(chǔ)上，未做任何操作

????@Override
????public?void?doFilter(ServletRequest?request,?ServletResponse?response,?FilterChain?chain)
????????????throws?IOException,?ServletException?{
????????//?TODO?Auto-generated?method?stub

????????HttpServletResponse?res?=?(HttpServletResponse)?response;
????????HttpServletRequest?req?=?(HttpServletRequest)?request;

????????String?origin?=?req.getHeader("Origin");
????????if?(!org.springframework.util.StringUtils.isEmpty(origin))?{
????????????//帶cookie的時候，origin必須是全匹配，不能使用*
????????????res.addHeader("Access-Control-Allow-Origin",?origin);
????????}

????????chain.doFilter(request,?response);
????}

二、測試表現(xiàn)

network 面板 》》

console 面板 》》

三、疑問

1、network 顯示一次 xhr 請求類型，沒有出現(xiàn) option；

2、“It does not have HTTP ok status.”一直沒找到解決方案。

1）postman直接測rest接口，是通過的：

2）后臺產(chǎn)生了異常日志
