Question

我正在使用Nginx运行WebDAV。我有一个JS应用程序将其用作存储。问题在于WebDAV扩展正在删除我在配置中使用“ add_header”添加的标头。

server {
  # IP, Certificates, fullpath, autoindex ...
  dav_methods      PUT DELETE MKCOL COPY MOVE;
  dav_ext_methods  PROPFIND OPTIONS;
  dav_access       user:rw group:rw all:rw;

  location / {
    root /srv/http/content;

    # Preflighted requests
    if ($request_method = OPTIONS) {
      add_header "Access-Control-Allow-Origin" *;
      add_header "Access-Control-Allow-Methods" "GET, HEAD, POST, PUT, OPTIONS, MOVE, DELETE, COPY, LOCK, UNLOCK, PROPFIND";
      add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept, DNT, X-CustomHeader, Keep-Alive,User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Range, Range, Depth";
      return 200;
    }

    if ($request_method = (GET|POST|HEAD|DELETE|PROPFIND)) {
      add_header "Access-Control-Allow-Origin" *;
      add_header "Access-Control-Allow-Methods" "GET, HEAD, POST, PUT, OPTIONS, MOVE, DELETE, COPY, LOCK, UNLOCK, PROPFIND";
      add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept";
    }
  }
}

当我从我的应用程序打开WebDAV连接时，它会先请求OPTIONS，然后再请求PROPFIND。请求OPTIONS通过具有正确的CORS标头而通过，但是PROPFIND失败，因为未设置CORS标头。请注意配置中OPTIONS的特殊情况，其中我强制Nginx返回Http200。然后出现标题。但是当让WebDAV完成时，所有的CORS标头都消失了。

有人绕过这种行为吗？

实际上，这是nginx的webdav中的错误。我可以使用lighttpd快速运行webdav（带有CORS，身份验证和SSL）。我的示例配置

server.port         = 81
server.username     = "http"
server.groupname    = "http"
server.modules      = (
    "mod_webdav",
    "mod_auth",
    "mod_setenv", # before mod_status, very important!
    "mod_status",
    "mod_openssl"
    )
server.document-root= "/srv/http/content"
server.errorlog     = "/var/log/lighttpd/error.log"
ssl.engine          = "enable"
ssl.pemfile         = "/etc/ssl/webdav.key"
webdav.activate     = "enable"
auth.backend        = "htpasswd"
auth.backend.htpasswd.userfile = "/srv/http/passwd"
setenv.add-response-header     = (
    "Access-Control-Allow-Origin" => "*",
    "Access-Control-Allow-Methods" => "GET, HEAD, POST, PUT, OPTIONS, MOVE, DELETE, COPY, LOCK, UNLOCK, PROPFIND",
    "Access-Control-Allow-Headers" => "Authorization, Origin, X-Requested-With, Content-Type, Accept, DNT, X-CustomHeader, Keep-Alive,User-Agent, X-Requested-With, If-Modified-Since,Cache-Control, Content-Range, Range, Depth, Content-Length"
    )
mimetype.assign     = (
                ".html" => "text/html",
                ".txt" => "text/plain",
                ".css" => "text/css",
                ".js" => "application/x-javascript",
                ".jpg" => "image/jpeg",
                ".jpeg" => "image/jpeg",
                ".gif" => "image/gif",
                ".png" => "image/png",
                "" => "application/octet-stream"
            )

我有同样的问题。

尝试将always关键字添加到add_header语句中：

add_header "Access-Control-Allow-Origin" * always;
add_header "Access-Control-Allow-Methods" "GET, HEAD, POST, PUT, OPTIONS, MOVE, DELETE, COPY, LOCK, UNLOCK, PROPFIND" always;
add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept, DNT, X-CustomHeader, Keep-Alive,User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Range, Range, Depth" always;

add_header文档：

语法：add_header名称值[始终];

将指定的字段添加到响应标头中，前提是   响应码等于200、201（1.3.10），204、206、301、302、303、304，   307（1.1.16，1.0.13）或308（1.13.0）。 [...]如果始终参数   指定为（1.7.5），则无论   响应代码。
