ajax的post请求如何让web或接口的方法支持跨域（）

只是方法，如果是服务器或者整个web，找其他资料

只需要加入

response.setHeader("Access-Control-Allow-Origin", "*");

即可

@ResponseBody@RequestMapping(value="login1", method=RequestMethod.GET, produces="application/json;charset=UTF-8")public String login1(HttpServletRequest request,HttpServletResponse response) throws Exception{response.setHeader("Access-Control-Allow-Origin", "*"); 

@ResponseBody@RequestMapping(value="login", method=RequestMethod.POST, produces="application/json;charset=UTF-8")public String login(@RequestBody String requestJson,HttpServletRequest request,HttpServletResponse response) throws Exception{//设置跨域请求response.setHeader("Access-Control-Allow-Origin", "*");

通过浏览器请求get获取通过360浏览器的console请求postvar data={thirdType:3,openId:"a970a9778",userName:"22288",headImage:"http://www.baidu.com/image.png"}$.ajax({type:"POST",dataType:"json",url:"http://192.168.1.5:8080/ryqp/login.shtml",data:data,success: function(msg){if(msg.code == "APP.000"){alert('删除成功');}else {alert("删除失败!");}},error: function (msg) {alert("删除失败!");}});
