I think you can try using an ajax call to do the post to the controller.
我认为您可以尝试使用 ajax 调用向控制器发送邮件。
as an example:
举个例子：
var jsonfile= {json:JSON.stringify(contents)};
$.ajax({
type:'POST',
url: "/yourcontrollermapping/signFaces.do
data: jsonfile,
dataType: "json"
});
and then your controller method:
然后你的控制器方法：
@Controller
@RequestMapping("/yourcontrollermapping"
public class YourController(){
@RequestMapping(value = "/signFaces.do, method = RequestMethod.POST)
public void getSignFaces(@RequestParam("json) String json){
//stuff you want to do
}
}
If you wanne do it javascript native you can :
如果你想这样做 javascript native 你可以：
var jsonfile= {json:JSON.stringify(contents)};
var r = new XMLHttpRequest(); r.open("POST", "yourcontrollermapping/signFaces.do", true); r.onreadystatechange = function () { if (r.readyState != 4 || r.status != 200) return; console.log(r.responseText); }; r.send(jsonFile);
