我正在尝试将CORS指令添加到我的nginx文件中,作为简单的静态HTML站点。 (取自http://enable-cors.org/server_nginx.html)
是否有理由抱怨第一个add_header指令说' add_header"这里不允许使用指令'
我的配置文件示例
server {
if ($http_origin ~* (https?://[^/]*\.domain\.com(:[0-9]+)?)$) {
set $cors "true";
}
if ($request_method = 'OPTIONS') {
set $cors "${cors}options";
}
if ($request_method = 'GET') {
set $cors "${cors}get";
}
if ($request_method = 'POST') {
set $cors "${cors}post";
}
if ($cors = "trueget") {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' 'true';
}
if ($cors = "truepost") {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' 'true';
}
if ($cors = "trueoptions") {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';
add_header 'Content-Length' 0;
add_header 'Content-Type' 'text/plain charset=UTF-8';
return 204;
}
listen 8080;
location / {
root /var/www/vhosts/mysite;
}
}
答案 0 :(得分:21)
add_header
必须置于http
,server
,location
或if in location
阻止之下。
您正在if in server
下。将它们移到location
块下。
server {
listen 8080;
location / {
root /var/www/vhosts/mysite;
if ($http_origin ~* (https?://[^/]*\.domain\.com(:[0-9]+)?)$) {
set $cors "true";
}
if ($request_method = 'OPTIONS') {
set $cors "${cors}options";
}
if ($request_method = 'GET') {
set $cors "${cors}get";
}
if ($request_method = 'POST') {
set $cors "${cors}post";
}
if ($cors = "trueget") {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' 'true';
}
if ($cors = "truepost") {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' 'true';
}
if ($cors = "trueoptions") {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';
add_header 'Content-Length' 0;
add_header 'Content-Type' 'text/plain charset=UTF-8';
return 204;
}
}
}

答案 1 :(得分:11)
规则if in location
可以通过一些技巧绕过,这样您就不必在每个location
块中编写/包含CORS规则。
server {
set $cors_origin "";
set $cors_cred "";
set $cors_header "";
set $cors_method "";
if ($http_origin ~* "^http.*\.yourhost\.com$") {
set $cors_origin $http_origin;
set $cors_cred true;
set $cors_header $http_access_control_request_headers;
set $cors_method $http_access_control_request_method;
}
add_header Access-Control-Allow-Origin $cors_origin;
add_header Access-Control-Allow-Credentials $cors_cred;
add_header Access-Control-Allow-Headers $cors_header;
add_header Access-Control-Allow-Methods $cors_method;
}
这是有效的,因为如果nginx的值为空字符串,则不会返回标头。
答案 2 :(得分:4)
首先,让我说在浏览网页后,我发现这个答案随处可见:
location ~* \.(eot|ttf|woff|woff2)$ {
add_header Access-Control-Allow-Origin *;
}
但是,我已经决定用一个单独的答案回答这个问题,因为我只是在花了大约十个小时寻找解决方案之后才设法使这个特定的解决方案工作。
默认情况下,Nginx似乎没有定义任何[正确]字体MIME类型。通过关注this tuorial我发现我可以添加以下内容:
application/x-font-ttf ttc ttf;
application/x-font-otf otf;
application/font-woff woff;
application/font-woff2 woff2;
application/vnd.ms-fontobject eot;
到我的etc/nginx/mime.types
文件。
如上所述,上述解决方案随后起作用。显然,这个答案旨在分享字体,但它绝对值得检查,以确定(正确)是否为您正在努力解决的任何其他资源定义了MIME类型。
