我在序言中遇到cors问题。我认为它不起作用。Prolog中的CORS不工作

但是我用ajax帖子序言服务器时,它说
XMLHttpRequest cannot load http://localhost:9999/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:1000' is therefore not allowed access. The response had HTTP status code 500.
阿贾克斯,我用它来发布。
let enemyName = this.item.text
let data = {"pokemon":enemyName}
$.ajax({
url : END_POINT,
method : 'post',
contentType: 'application/json',
dataType : 'json',
data : JSON.stringify(data),
success : function (res) {
console.log(res);
},
error :function (res) {
console.log(res);
}
})
我该如何解决这个问题?
