apache2 设置 cross-origin resource sharing

现在的浏览器,有些 ajax 请求,会先执行 pre-flight , 导致即使服务器配置了 Access-Control-Allow-Origin, 依然会报跨域请求的错误.

这里记录下在 apache 里的解决方法.

打开 rewrite mod

conf/httpd.confapache 1行

1LoadModule rewrite_module modules/mod_rewrite.so

conf/conf-available/dav.confapache 10行

1# Always set these headers. 
2Header always set Access-Control-Allow-Origin "*" 
3Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT" 
4Header always set Access-Control-Max-Age "1000" 
5Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token" 
6  
7# Added a rewrite to respond with a 200 SUCCESS on every OPTIONS request. 
8RewriteEngine On 
9RewriteCond %{REQUEST_METHOD} OPTIONS 
10RewriteRule ^(.*)$ $1 [R=200,L] 

参考文章

https://suziwen.github.io/acorns/tech/setting-cors-cross-origin-resource-sharing-on-apache-with-correct-response-headers-allowing-everything-through

即使按照上面的方法,还是会有 401 的错误, 最后版本.

添加 LimitExcept OPTIONS 信息

1<Directory "/var/lib/dav/data/"> 
Dav On 
Options Indexes FollowSymLinks 
4 
# Always set these headers. 
6 
Header always set Access-Control-Allow-Origin "*" 
Header always set Access-Control-Allow-Headers "*" 
Header always set Access-Control-Expose-Headers "ETag" 
Header always set Access-Control-Allow-Methods "*" 
Header always set Access-Control-Allow-Credentials "true" 
# Added a rewrite to respond with a 200 SUCCESS on every OPTIONS request. 
RewriteEngine On 
RewriteCond %{REQUEST_METHOD} OPTIONS 
RewriteRule ^(.*)$ blank.html [R=200,L,E=HTTP_ORIGIN:%{HTTP:ORIGIN}] 
AuthType Basic 
AuthName "WebDAV" 
AuthUserFile "/user.passwd" 
<LimitExcept OPTIONS> 
  Require valid-user 
</LimitExcept> 
22</Directory> 
23 

docker 启动失败分析处理

由于直接在 docker 容器里修改了文件,导致容器无法正常启动.(注:不建议直接在容器内修改文件)

1docker ps -a 
2docker logs {容器id} 

报错信息

1Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration 

重新修改配置文件 , 将 rewrite mods 打开

1docker cp {容器id}:/usr/local/apache2/conf/conf-available/dav.conf ./ 
2vi dav.conf 
3docker cp ./dav.conf {容器id}:/usr/local/apache2/conf/conf-available/ 

webdav 协议不支持递归创建不存在的目录问题

1# 逆向递归创建目录 
2ensureDir = (client, paths, cb)-> 
client.exists(paths.join("/")).then((isExists)-> 
  if isExists 
    # 结束递归 
    cb() 
  else 
    if paths.length <= 1 
      # 创建最开始一层的目录,并结束递归 
      client.createDirectory(paths.join("/")).then(()-> 
        cb() 
      ).catch((error)-> 
        cb(error) 
      ) 
    else 
      ensureDir(client, paths.slice(0, -1), (error)-> 
        if error 
          cb(error) 
        else 
          client.createDirectory(paths.join("/")).then(()-> 
            cb() 
          ).catch((error)-> 
            cb(error) 
          ) 
      ) 
)
