/SBIN/Mount.davfs：安装失败；该服务器不支持WebDav

Question

我正在尝试安装一个远程WebDav：

sudo Mount -t davfs https://files.isric.org/soilgrids/latest/data/〜/webdav

，但我只会收到以下错误： /sbin/mount.davfs：安装失败；该服务器不支持WebDav

此服务器是 wsgidav 在kubernetes群集中运行。

Nautilus的同样问题，使用 gvfsd-dav 来调试问题，如所示在这里。我有以下服务器的HTTP请求/响应：

/usr/libexec/gvfsd-dav ssl=true user=anonymous host=files.isric.org  prefix=/soilgrids/latest/data/

服务器HTTP响应是 http/1.1 204没有内容

Answer 1

问题在于具有：

apiVersion: networking.k8s.io/v1 
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "GET, OPTIONS, HEAD"
    nginx.ingress.kubernetes.io/cors-allow-headers: "Content-Type, Accept-Ranges, Content-Range, Range, Content-Encoding, Content-Length, Access-Control-Allow-Origin"

http/1.1 204没有内容响应的K8S入口是正确的前飞行员响应，由提供入口，这是不是预期的WebDav Reponse ，第一个请求甚至没有达到运行WSGIDAV的POD。

解决方案：禁用入口上的CORS支持。然后还可以：
