Laravel 5 CORS - XMLHttpRequest无法加载http://myapi.com。预检的响应具有无效的HTTP状态代码500 [英] Laravel 5 CORS - XMLHttpRequest cannot load http://myapi.com. Response for preflight has invalid HTTP status code 500

问题描述

我使用Laravel 5和一个名为CORS的库。我面对一个错误，我不真正明白它是什么，为什么会发生。

我正在开发的API，将被网站的前端-end和一个应用程序。

我想对api进行ajax调用：

  $。ajax（{
 url：'http://myapi.com/call'，
 type：'GET'，
 headers：{'Authorization' ：'Bearer token123'}，
 crossDomain：true，
 contentType：'application / x-www-form-urlencoded; charset = UTF-8'，
 success：function console.log（data）;}，
 error：function（xhr）{console.log（xhr）} 
}）; 
  

但是我得到了这个错误：

  XMLHttpRequest无法加载http://myapi.com/call。响应预检具有无效的HTTP状态代码500 
  

但是，当我从请求中删除以下行时罚款。

  headers：{'Authorization'：'Bearer token123'}，
  
 
 
 
编辑：my config / cors.php 
  'supportsCredentials'=> false，
'allowedOrigins'=> ['*']，
'allowedHeaders'=> ['*']，
'allowedMethods'=> ['GET'，'POST'，'PUT'，'DELETE'，'OPTIONS']，
'exposedHeaders'=> []，
'maxAge'=> 0，
'hosts'=> []，
  
有关如何解决这个问题的任何想法吗？
 > ＃一个方法是在.htaccess中添加以下内容（相应地修改）
 
头添加Access-Control-Allow-Origin*
头添加访问-Control-Allow-Headersorigin，x-requested-with，content-type
 Header add Access-Control-Allow-MethodsPUT，GET，POST，DELETE，OPTIONS

I am using Laravel 5 and a library called CORS. I am facing an error that I don't really understand what it is and why it is happening.

I am developing an API that is gonna be used by a website's front-end and an app.

I am trying to do an ajax call to the API:
$.ajax({
  url: 'http://myapi.com/call',
  type: 'GET',
  headers: {'Authorization' : 'Bearer token123'},
  crossDomain: true,
  contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
  success   : function(data) { console.log(data);},
  error: function(xhr) {console.log(xhr)}
});
However I got this errro:
XMLHttpRequest cannot load http://myapi.com/call. Response for preflight has invalid HTTP status code 500
However, when I remove the following line from the request works fine.
headers: {'Authorization' : 'Bearer token123'},
EDIT: my config/cors.php
'supportsCredentials' => false,
'allowedOrigins' => ['*'],
'allowedHeaders' => ['*'],
'allowedMethods' => ['GET', 'POST', 'PUT',  'DELETE', 'OPTIONS'],
'exposedHeaders' => [],
'maxAge' => 0,
'hosts' => [],
Any idea about how to solve it?
解决方案
Did you configure CORS on server in laravel, there are couple of option to do the same 
# one of the way is to add below in .htaccess (modify accordingly)

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

# other options you can refer to below link of laracasts
