在登录页面上接收到来自Nginx服务器的404错误，并对同一域进行javascript-ajax调用

请帮忙：-）

我正在用NGINX设置我的web服务器，但我遇到了一个似乎与CORS有关的错误

在浏览器的控制台上，当我键入：$.get（“/logon？action=login”）；击中 输入成功执行请求并返回正确的 数据

但是，如果我键入：$.post（“/logon？action=login”）；点击回车键，它会给出 告诉我404/找不到错误

我的登录URL如下所示：

其中，用户通知其凭据并单击触发“mySubmit（）”函数的发送按钮

<div>
  <input type='text' name='user'>
  <input type='password' name='password'>
  <button onclick='mySubmit'>Submit</button>
</div>

<script>
function mySubmit() {
    $.ajax({
        type: 'POST',
        url: '/logon?action=login',
        data: { user: 'john', password: 'secret' },
        async: false,
        error: function(err){
                console.log('err',err);
            },
        success: function(data) {
                console.log('success',data);
            }
    });
}
</script>
