{

"headers": [

{

"source": "/(.*)",

"headers": [

{ "key": "Access-Control-Allow-Credentials", "value": "true" },

{ "key": "Access-Control-Allow-Origin", "value": "*" },

{ "key": "Access-Control-Allow-Methods", "value": "GET,OPTIONS,PATCH,DELETE,POST,PUT" },

{ "key": "Access-Control-Allow-Headers", "value": "X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Content-Type, Date, X-Api-Version" }

]

}

]

}

source 就是允许跨域的路径,我这边设置的是所有路径,即在这个网站上任何路径跨域都是可以的
