怎么在js的post中加入accept=json

怎么在js的post中加入accept=json

$.post() 不支持加入 headers 信息，改用 $.ajax()。demo 如下：
function getCode(param, config, notice) {
var url = config.apiBase
+ "/resource/";
var data = {
"name": param.name,
"user_agent": param.ua,
"mobile": $("#phone").val()
};

$.ajax({
url: url,
type: 'post',
data: data,
headers: {
"X-Requested-Accept": 'json'
},
dataType: 'json',
success: function (data) {
console.log(data);
if (data.ret) {
notice.showMsg({
msg: "短信验证码已经发送。",
type: "info",
deley: 0,
duration: 0,
close: true
});
countDown();
} else {
notice.showMsg({
msg: "短信验证码发送失败。",
type: "error",
deley: 0,
duration: 0,
close: true
});
}
}
});
}
