He māngai o to taatau kiritaki, ko tana puranga tono kei roto i te kapua Microsoft (Azure), i whakatika i tetahi raruraru: i tata nei, ka timata etahi tono mai i etahi o nga kiritaki mai i Uropi ki te mutu ki te hapa 400 (). Kua tuhia nga tono katoa ki te .NET, kua horahia ki Kubernetes...
Ko tetahi o nga tono ko te API, ka tae mai nga waka katoa. Ka whakarongohia tenei waka e te tūmau HTTP , i whirihorahia e te kiritaki .NET me te manaaki i roto i te pākākano. Na te patuiro, i waimarie matou i te mea he kaiwhakamahi motuhake nana i whakaputa te raru i nga wa katoa. Heoi, he uaua nga mea katoa na te mekameka waka:
Ko te hapa i roto i te Ingress te ahua penei:

}I taua wa ano, ka hoatu e Kestrel:

}Ko te ahua ko te tcpdump anake ka awhina i tenei raru ... engari ka korero ano ahau mo te mekameka waka:
Te whakatewhatewha
Ko te tikanga, he pai ake te whakarongo ki nga waka i runga i taua node motuhake, i te wahi i tukuna ai e Kubernetes he putunga: ka rite te rahi o te putunga ka taea te kimi i tetahi mea tino tere. Ae, i te wa e tirotirohia ana, ka kitea te anga e whai ake nei:
GET /back/user HTTP/1.1

HTTP/1.1 400 Bad Request

Server: Kestrel
Content-Length: 0
I te ata tirotiro i te putunga, ka kitea te kupu M.laga. He ngawari ki te whakaaro kaore he taone M.laga i Spain (engari kei reira ). I te hopu i tenei whakaaro, ka titiro matou ki nga whirihora Ingress, i kite matou i te mea kua whakauruhia i te marama ki muri (i te tono a te kiritaki) "kore kino" snippet:
ingress.kubernetes.io/configuration-snippet: |
proxy_set_header X-Nginx-Geo-Client-Country $geoip_country_name;
proxy_set_header X-Nginx-Geo-Client-City $geoip_city;I muri i te whakakore i te tuku whakamua o enei pane, ka pai katoa! (Kare i roa kua marama kua kore e hiahiatia e te tono enei pane.)
Inaianei ka titiro tatou ki te raru te nuinga ake. Ka ngawari te whakaputa i roto i te tono ma te tono waea waea ki localhost:80:
GET /back/user HTTP/1.1
Host: api.app.example.com
cache-control: no-cache
accept: application/json, text/plain, */*
origin: https://app.example.com
Cookie: test=Desiree
... hoki mai 401 Unauthorized, rite ki te tumanako. Ka aha mena ka mahi tatou:
GET /back/user HTTP/1.1
Host: api.app.example.com
cache-control: no-cache
accept: application/json, text/plain, */*
origin: https://app.example.com
Cookie: test=Désirée?
Ka hoki mai 400 Bad request — i roto i te raarangi tono ka whiwhi tatou i tetahi hapa kua maarama ki a maatau:
{
"@t":"2019-03-31T12:59:54.3746446Z",
"@mt":"Connection id "{ConnectionId}" bad request data: "{message}"",

"message":"Malformed request: invalid headers.",

}Ngā putanga
Ina koa ko Kestrel te tukatuka tika i nga pane HTTP me nga tohu tika i roto i te UTF-8, kei roto i nga ingoa o te maha o nga taone nui.
Ko tetahi atu take i roto i ta maatau keehi ko te kore e whakamahere te kaihoko ki te whakarereke i te whakatinanatanga o Kestrel i roto i te tono. Heoi ano, nga take kei AspNetCore ake (, ) e kii ana ratou kaore tenei e awhina ...
Hei whakarāpopototanga: ko te tuhipoka kaore ano mo nga raru motuhake o Kestrel, UTF-8 ranei (i te 2019?!), engari mo te meka te mahara me te ako tonu Ko nga hikoinga katoa ka mahia e koe i a koe e rapu ana i nga raru ka whai hua. Waimarie!
