nginx/tomcat添加自定义header 403 forbidden

nginx/tomcat处理跨域请求的时候都会有一个白名单,默认情况下只会允许常见的一些自定义header,如果是个性一点的自定义header就会被白名单过滤掉,直接返回403                  

重点是添加 Access-Control-Allow-Headers:"自定义header"

#
# Wide-open CORS config for nginx
#
location / {
     if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        #
        # Custom headers and headers various browsers *should* be OK with but aren't
        #
        add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type
,自定义header';
        #
        # Tell client that this pre-flight info is valid for 20 days
        #
        add_header 'Access-Control-Max-Age' 1728000;
        add_header 'Content-Type' 'text/plain charset=UTF-8';
        add_header 'Content-Length' 0;
        return 204;
     }
     if ($request_method = 'POST') {
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-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
,自定义header';
 } if ($request_method = 'GET') { add_header 'Access-Control-Allow-Origin' '*'; 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
,自定义header';
 }}

tomcat需要配置web.xml中的filter cors.allowed.headers

  CorsFilter
  org.apache.catalina.filters.CorsFilter
  
    cors.allowed.origins
    *
  
  
    cors.allowed.methods
    GET,POST,HEAD,OPTIONS,PUT
  
  
    cors.allowed.headers
    Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers,自定义header
  
  
    cors.exposed.headers
    Access-Control-Allow-Origin,Access-Control-Allow-Credentials
  
  
    cors.support.credentials
    true
  
  
    cors.preflight.maxage
    10
