ps:ajax跨域請(qǐng)求 放棄使用POST + JSON

原先寫(xiě)法POST + JSON，怎么試都不能訪(fǎng)問(wèn)

 @ResponseBody
    @RequestMapping(value = "/public/courseware/apply", method = RequestMethod.POST)
    public Object apply(@RequestBody Courseware params, HttpServletResponse response) {
        try {
            response.addHeader("Access-Control-Allow-Origin", "*");
             ...
            return ResponseObject.success();
        } catch (InvalidFieldException e) {
             ...
            return ResponseFailureObject.getErrorMessage(e);
        } catch (Exception e) {
            ...
            return ResponseFailureObject.commonError();
        }
    }

放棄JSON請(qǐng)求方式修改如下

 @ResponseBody
    @RequestMapping(value = "/public/courseware/apply", method = RequestMethod.POST)
    public Object apply(HttpServletResponse response,
                                  @RequestParam(value = "name") String name,
                                  @RequestParam(value = "mobile") String mobile,
                                  @RequestParam(value = "email") String email) {
        try {
            response.addHeader("Access-Control-Allow-Origin", "*");
            ...
            return ResponseObject.success();
        } catch (InvalidFieldException e) {
             ...
            return ResponseFailureObject.getErrorMessage(e);
        } catch (Exception e) {
             ...
            return ResponseFailureObject.commonError();
        }
    }

修改后可以成功訪(fǎng)問(wèn)。
