最近有同事提出在使用客户端跨域访问的时候,发现服务器对option请求返回了403,后来查看了网络添加了一段配置,发现option服务返回204了,但是后续的put操作也直接返回了204导致无法使用图片上传功能,经过一番查询才发现,原来put等请求也需要定义,不然会直接使用option那段配置的请求

#首先nginx需要支持dav_module模块

./configure --prefix=/home/zqlx/apps/usr/webserver/nginx-1.12.0 --with-http_stub_status_module --with-http_ssl_module --user=zqlx --group=zqlx --with-pcre --with-pcre-jit --add-module=/tmp/nginx_upstream_check_module-master --with-stream --with-http_dav_module

#配置文件加上以下配置

location /aaa {

add_header 'Access-Control-Allow-Origin' '*';

add_header 'Access-Control-Allow-Credentials' 'true';

#if ($request_method = "OPTIONS") {

# add_header 'Access-Control-Allow-Origin' "*";

# add_header 'Access-Control-Allow-Credentials' "true";

# add_header 'Access-Control-Max-Age' 86400;

# add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, DELETE';

# add_header 'Access-Control-Allow-Headers' 'reqid, nid, host, x-real-ip, x-forwarded-ip, event-type, event-id, accept, content-type';

# add_header 'Content-Length' 0;

# add_header 'Content-Type' 'application/json, charset=utf-8';

# return 204;

#}
