关于access control allow origin header is present错误 nginx

Question

准备部署一个本地系统，然后请求后端是使用https,结果发现登录的接口没问题，提交数据的接口就出问题了，
问题：
Failed to load resource: the server responded with a status of 500 ()
input.html:1 Failed to load https://127.0.0.1/acquisition...: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1' is therefore not allowed access. The response had HTTP status code 500.

使用了jquery 提交；
后台 nginx.conf 部分 配置：

# Begin HTTPS Server
server {

       
       add_header Access-Control-Allow-Origin "http://127.0.0.1";
       #add_header Access-Control-Allow-Origin *;
       add_header Access-Control-Allow-Credentials true;
       add_header Access-Control-Allow-Headers "x-requested-with,Authorization";
       add_header Access-Control-Allow-Methods *;
   }
   
   # return 404 for all other php files not matching the front controller
   # this prevents access to other php files you don't want to be accessible.
   location ~ \.php$ {
     return 404;
   }

   error_log project_error.log;
   access_log project_access.log;
} # End HTTPS Server
}

jquery已经在请求头加上 withCredential, crossDomain等字段的；在未部署成localhost本机访问之前都是可用的

请求方法：

$.ajax({
    type:"post",
    url: "https://127.0.0.1/post",
    data: data,
    success: function(){},
    error: function(){}
})

你这是跨域问题。请搜索CORS。
需要服务器端逻辑中添加特殊的响应头，允许从其它网站（即跨域）往本服务器发送Ajax请求。
客户端（调用端）是无法解决的。
