nginx的location配置导致网关返回404
再项目中使用nginx转发到网关时，发现返回了404.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | { "timestamp": "2023-11-01T02:12:48.788+00:00", "path": "//core-manage-web/core/core-manage/servers/findServers", "status": 404, "error": "Not Found", "message": null, "requestId": "642b125b"} |
从这个返回来看，应该是网关返回的信息。因为如果是nginx返回404的话，应该是返回的404.html才对。
所以看看出是网关找不到转发的路径。 从 “path”: “//core-manage-web/core/core-manage/servers/findServers”，看出我们的接口经过nginx转发之后，居然只有两个//。正常应该只有一个才对。
再看一下location配置：
1 2 3 | location /core { proxy_pass http://gateway-upstream/;} |
由于第一次使用使用nginx，所以对于这些配置还不是很了解。这上面的的 “location /core”标识路径前缀匹配。 而我的 “http://core-gateway-upstream/”是以“/”结尾，这表示会将 location的匹配路径(/core)替换掉在转发。
gateway-upstream配置如下
1 2 3 | upstream gateway-upstream { server 192.168.111.1:10006;} |
所以如果我是用 http:localhost:8080/core/login/xxxxx访问，则经过nginx转发之后会变成192.168.111.1:10006//login/xxxxx
所以需要将 location /core改成 location /core/。即可：
1 2 3 | location /core/ { proxy_pass http://gateway-upstream/;} |
nginx配置多个location访问报404
解决方法
在自己配置的location中不要使用root配置文件目录，替换为alias即可
