jq 在ajax中带上headers后报错

Question

js代码：

 var requert = $.ajax({
        url: object.url
        data: object.data || '',
        type: object.method || 'POST',
        dataType: object.dataType || 'json',
        headers:{
                'token':'1233211234567'
        },
        success: function(res){
                // console.log(res)
                object.success(res);
        },
        error: function (res,errMsg) {  
                throw errMsg
        },
        complete: function (param) {  
                // console.log(param);
        }
    })
    if(object && object.ajaxParam){
            object.ajaxParam(requert);
    }
}

加上 headers 之后，就一直报错，

 Access to XMLHttpRequest at 'http://101.132.158.167:86/index.php/index/index/lishiclass' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

然后我在 php 端加上：

 header('Access-Control-Allow-Origin:*');
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Methods:PUT,POST,GET,DELETE,OPTIONS');
header('Access-Control-Allow-Headers:X-Requested-With,token,origin'); 
header('Content-Type:application/json;charset=utf-8');

也无法解决问题，有没有大神帮帮忙，谢谢

加上headers之后，header已经不是正常情况的数据了，后台不作处理定会报错，应该上php端有错，配置没有没有生效。
