每一次都这么写太麻烦了,可以使用$.ajaxSetup()方法为ajax请求统一设置。
function csrfSafeMethod(method){
// these HTTP methods do not require CSRF protection
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method);
}
$.ajaxSetup({
beforeSend: function(xhr, settings){
if (!csrfSafeMethod(settings.type) && !this.crossDomain){
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
})
