Inside the virtual service, I have routed 2 paths to my service as follows -
- match:
- uri:
prefix: /jaeger/
- uri:
regex: \/oauth2\/.*jaeger.*
route:
- destination:
host: oauth2-proxy
port:
number: 80
But the gateway returns 404 when I send request on the path /oauth2/callback?code=3QxQLUqCwxVtH_GS6mWteICfisIe32yE7RE6wQIZZVw&state=wmZSZ0BHMHq3vmS_1YBWIn72pG6FkChFQbNUNipGotQ:/jaeger/
Now, I could also just use the prefix /oauth2/
to handle such URLs but currently I have multiple applications that are being authenticated by their own oauth2-proxies and this regex would match all of them. So I need to use a regex which contains the application name inside it, such as jaeger is this case.
I even checked on regex101 that this path is indeed matching the regex I used.
Also, the gateway routes the request successfully when I use the regex \/oauth2\/.*
. But as I explained I can't use this regex either. Am I missing something here?
Edit:
After further testing, I found out that if remove the "?" from the path, istio accepts this as valid and forwards the request to the service.
I also tried the regex /oauth2\/callback\?code=.*jaeger.*
but that isn't working either.
CodePudding user response:
I did not realize that "?" marks the end of a URL and everything after that are query parameters. Istio provides matching of query parameters as well. The following code worked in my case -
- match:
- uri:
prefix: /jaeger/
- uri:
regex: \/oauth2\/callback?.*
queryParams:
state:
regex: .*jaeger.*
route:
- destination:
host: oauth2-proxy
port:
number: 80
