The server allows other domain names to access data across domains by setting the response header.

Set the response header:

# Cross-origin domains are allowed. * indicates that all domains receive

Access-control-allow-origin: http://foo.example

# Methods that allow cross-origin execution

Access-control-allow-Methods: Post, get, options

# Header information that allows cross-origin settings

Access-control-allow-headers: X-PINGOTHER

The following is the nginx method
if ($ request_method = 'options ') {
add_header access-control-allow-origin *;
add_header access-control-allow-Credentials true;
add_header access-control-allow-methods 'get, post, options';
add_header 'access-control-allow-headers' 'DNT, x-Mx-reqtoken, keep-alive, User-Agent, X-requested-with, if-modified-since, cache-control, Content-Type ';
return 200;
}< br> if ($ request_method = 'post') {

Add_header 'access-control-allow-origin '*;
Add_header 'access-control-allow-Credentials ''true ';
Add_header 'access-control-allow-methods ''' get, post, options ';
Add_header 'access-control-allow-headers' DNT, X-Mx-reqtoken, keep-alive, User-Agent, X-requested-with, if-modified-since, cache-control, Content-Type ';

}

If ($ request_method = 'get '){

Add_header 'access-control-allow-origin '*;
Add_header 'access-control-allow-Credentials ''true ';
Add_header 'access-control-allow-methods ''' get, post, options ';
Add_header 'access-control-allow-headers' DNT, X-Mx-reqtoken, keep-alive, User-Agent, X-requested-with, if-modified-since, cache-control, Content-Type ';

}
