使用JSON在Ajax调用上获得400错误

I'm not sure what's wrong with the way I'm doing this... I get a 400 Error saying it's a bad request, but I can't find anything wrong with my syntax.

我不确定我这样做的方式有什么问题...我得到一个400错误，说这是一个糟糕的请求，但我发现我的语法没有任何问题。

$.ajax({
        url : '/my_project/rest/runs/1234?token=moo',
        type : 'POST',
        data: { job_position : JSON.stringify(38) },
        contentType: 'application/json',
        dataType: 'json',
        success : function(html) {
        }
    });

The receiving controller:

接收控制器：

@RequestMapping(value="/runs/{userId}", method = RequestMethod.POST, consumes = {"application/json"})
    public @ResponseBody boolean myMethod(@PathVariable String userId, @RequestParam("token") String authenticationToken, @RequestBody @Valid Long job_position){
        return true;
    }

Your not actually sending JSON in your request, jQuery will convert your object to a query string. To prevent this stringify it yourself.

您实际上并未在请求中发送JSON，jQuery会将您的对象转换为查询字符串。为了防止这个字符串化自己。

$.ajax({
        url : '/my_project/rest/runs/1234',
        type : 'POST',
        data: JSON.stringify({ job_position : 38, token: 'moo' }),
        contentType: 'application/json',
        dataType: 'json',
        success : function(html) {
        }
});

Is your data part missing quotes? data: { "job_position" : JSON.stringify(38) }

您的数据部分是否缺少引号？ data：{“job_position”：JSON.stringify（38）}

Just a thought.

只是一个想法。

/my_project/rest/runs/1234?token=moo - it's GET request sintax

/ my_project / rest / runs / 1234？token = moo - 这是GET请求sintax

make
url : '/my_project/rest/runs/1234'
and
data: { "job_position" : JSON.stringify(38) , "token" : "moo"}

make url：'/ my_project / rest / runs / 1234'和data：{“job_position”：JSON.stringify（38），“token”：“moo”}

so full request look like

如此完整的请求看起来像

$.ajax({
        url : '/my_project/rest/runs/1234',
        type : 'POST',
        data: { "job_position" : 38, "token" : "moo"},
        contentType: 'application/json',
        dataType: 'json',
        success : function(html) {
        }
    });
