我尝试解决向GeoServer发送请求时收到的错误403 Forbidden。要调试该过程，我使用Chrome中的Inspect选项中的Network选项卡（我也尝试过Firefox）。这是我在“网络”选项卡中看到的错误。
XMLHttpRequest无法加载 http://localhost:8080/geoserver/square/ows?service=WFS&version=1.1.0&requ ... TURE＆安培;的typeName =正方形：InformationStores＆安培; OUTPUTFORMAT =应用％2Fjson。 对预检请求的响应没有通过访问控制检查：否 ＆＃39;访问控制允许来源＆＃39;标题出现在请求的上 资源。起源＆＃39; http://localhost:5601＆＃39;因此是不允许的 访问。响应的HTTP状态代码为403。
根据我在此主题中找到的多个教程，我的GeoServer 2.10.4已启用CORS。但是，我收到的错误消息似乎与代理有关。
我花了很多时间试图解决这个问题，所以最后，我绝对迷失了。我尝试了很多东西，但没有任何效果。
这是我发送请求的GeoServer的配置文件：

<!-- Meaning of the different values :
PARTIAL-BUFFER2
- Partially buffers the first xKb to disk. Once that has buffered, the the
result is streamed to the user. This will allow for most errors to be caught
early.
BUFFER
- stores the entire response in memory first, before sending it off to
the user (may run out of memory)
SPEED
- outputs directly to the response (and cannot recover in the case of an
error)
FILE
- outputs to the local filesystem first, before sending it off to the user
