The front end is accessed across domains. How to configure nginx

after nginx is configured to access cross-domain access, get,post can be accessed, but the put method is not allowed

the specific configuration is as follows

add_header Access-Control-Allow-Origin *;

location / {
   if ($request_method = "OPTIONS") {
    add_header Access-Control-Allow-Origin *;
    add_header Access-Control-Allow-Headers X-Requested-With;
    add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;
    return 204;
}

then reported the wrong prompt

index.html:1 Failed to load http://ms.iot-sw.net:7880/service/v1/shareport/park/4: Method PUT is not allowed by Access-Control-Allow-Methods in preflight response.

does any great god know how to configure and support the put method

Cross-domain nginx

this configuration only handles OPTIONS requests. The OPTIONS request is not forwarded to the backend, but returns 204 directly, and cross-domain is allowed.

for other requests, you need to add another paragraph before:

location / {
   add_header Access-Control-Allow-Origin *;
   add_header Access-Control-Allow-Headers X-Requested-With;
   add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;
    
   if ($request_method = 'OPTIONS') {
     return 204;
   }
}
