Trying to figure out what to use to set CORS.
As I came across this package, was wondering what is the difference between this one and @koa/cors?
dist folder file is same with src fix it ,
return async function (ctx, next) {
^^^^^^^^
SyntaxError: Unexpected token function
哥们 dist 目录的文件没bable 转译
"axios": "latest",
"koa": "latest",
"koa-body": "latest",
"koa2-cors": "latest",
"koa-router": "latest",
"require-directory": "latest",
"form-data": "latest"
使用到这些库
app.use(cors({
origin: 'http://localhost:8080'
}));
This setting is no problem on the localhost:8080 service.
But I also want to configure a service on the 8081 port should be configured?
I found the code below:
if (options.allowHeaders) {
ctx.set('Access-Control-Allow-Headers', options.allowHeaders.join(','));
} else {
ctx.set('Access-Control-Allow-Headers', ctx.get('Access-Control-Request-Headers'));
}
}
And I have a question of that if it is safe to use the value of Access-Control-Request-Headers
for Access-Control-Allow-Headers
or maybe I misunderstand the usage of the Access-Control-Request-Headers
.
