跨域请求
如果某个路由或者分组需要支持跨域请求,可以使用
Route::get('new/:id', 'News/read')
->ext('html')
->allowCrossDomain();
跨域请求一般会发送一条
OPTIONS
的请求,一旦设置了跨域请求的话,不需要自己定义OPTIONS
请求的路由,系统会自动加上。
跨域请求系统会默认带上一些Header,包括:
Access-Control-Allow-Origin:*
Access-Control-Allow-Methods:GET, POST, PATCH, PUT, DELETE
Access-Control-Allow-Headers:Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With
你可以添加或者更改Header信息,使用
Route::get('new/:id', 'News/read')
->ext('html')
->allowCrossDomain([
'Access-Control-Allow-Origin' => 'thinkphp.cn',
'Access-Control-Allow-Credentials' => 'true'
]);
V6.0.3+
版本开始增加了默认的预检缓存有效期(默认为30分钟),你可以自定义有效期,例如:
Route::get('new/:id', 'News/read')
->ext('html')
->allowCrossDomain([
'Access-Control-Allow-Origin' => 'thinkphp.cn',
'Access-Control-Allow-Credentials' => 'true',
'Access-Control-Max-Age' => 600,
]);
