随着 RESTFul 的流行，就会牵扯到跨域问题，那么小伙伴有没有被坑过，高人绕过，有需求的请往下看：
location / {
if ($request_method = ‘OPTIONS‘) {
add_header ‘Access-Control-Allow-Origin‘ ‘*‘;
#
# Om nom nom cookies
#
add_header ‘Access-Control-Allow-Credentials‘ ‘true‘;
add_header ‘Access-Control-Allow-Methods‘ ‘GET, POST, OPTIONS‘;
#
# Custom headers and headers various browsers **should** be OK with but aren‘t
#
add_header ‘Access-Control-Allow-Headers‘ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type‘;
#
# Tell client that this pre-flight info is valid for 20 days
#
add_header ‘Access-Control-Max-Age‘ 1728000;
add_header ‘Content-Type‘ ‘text/plain charset=UTF-8‘;
add_header ‘Content-Length‘ 0;
return 204;
}
if ($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-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type‘;
}
if ($request_method = ‘GET‘) {
add_header ‘Access-Control-Allow-Origin‘ ‘*‘;
add_header ‘Access-Control-Allow-Credentials‘ ‘true‘;
add_header ‘Access-Control-Allow-Methods‘ ‘GET, POST, OPTIONS‘;
add_header ‘Access-Control-Allow-Headers‘ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type‘;
}
}
大家看这代码是否有点臃肿？那么这样呢？
location / {
add_header ‘Access-Control-Allow-Origin‘ ‘*‘;
add_header ‘Access-Control-Allow-Credentials‘ ‘true‘;
add_header ‘Access-Control-Allow-Methods‘ ‘GET, POST, PUT, DELETE, OPTIONS‘;
add_header ‘Access-Control-Allow-Headers‘ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Token‘;
if ($request_method = ‘OPTIONS‘) {
add_header ‘Access-Control-Max-Age‘ 1728000;
add_header ‘Content-Length‘ 0;
return 204;
}
}
依然可以达到跨域效果，但是有什么缺点，欢迎交流~
