众所周知，HTML5的CORS协议，支持各种request method，远胜于仅支持get方式的JSONP。
但今天，我用CORS协议，却一直不成功。
跨域异常，如图
POST http://10.19.66.52/mts-web/register/sendAuthCode.do 400 (Bad Request) jquery.min.js:1 XMLHttpRequest cannot load http://10.19.66.52/mts-web/register/sendAuthCode.do. No ‘Access-Control-Allow-Origin‘ header is present on the requested resource. Origin ‘http://oasit.cnsuning.com‘ is therefore not allowed access.
然后我在服务器端，设置：
response.setHeader("Access-Control-Allow-Origin", request.getHeader("Access-Control-Allow-Origin"));
response.setHeader("Access-Control-Allow-Credentials", "true");
但一直不可以，报400 响应码。
我观察后台代码，可能阻止服务器响应的，大概
method = RequestMethod.POST @RequestParam
@RequestMapping(value = "register/sendAuthCode", method = RequestMethod.POST) public String sendAuthCode(@RequestParam String mobilenum, HttpServletResponse response, HttpServletRequest request) { Map<String, String> responseMap = purseService.sendAuthCode(HttpUtil.getClientIP(request), mobilenum);
将这两条删掉，果然好了！！！
先Mark，以后再补上冲突原理。
