Custom Query (2297 matches)

Similar Issue with here: ​https://github.com/kubernetes/ingress-nginx/issues/4039

Background: I configured a custom error page on Nginx based on the Accept Header.

For example: curl -i ​https://test-nginx.text.com/api/nginxTest/502 --header 'Accept: application/json'. It would return on cli like this:

HTTP/1.1 502 Bad Gateway
Server: nginx
Date: Mon, 22 Jul 2019 00:16:13 GMT
Content-Type: application/json
Content-Length: 115
Connection: keep-alive
ETag: "5d301e25-73"
X-Content-Type-Options: nosniff

{
  "result" : "ERROR",
  "apiErrorCode" : -1,
  "message" : "Bad gateway",
  "localizedMessage" : "Bad gateway"
}

But if I didn't pass any Accept header. The default text/html should handle it. In cli, it shows the HTML error page but when I tried to access it on a browser the HTML error page would not show.

In Google Chrome v 75.0.3770.142 : It shows "ERR_INVALID_SIGNED_EXCHANGE" In Safari v 12.1: It would download the page In Mozilla Firefox v63.0.3: It would show the custom XML custom error page The code should return a default content-type header text/html, but when it fails to decode the Accept header, it simply mirrors whatever came from the request into the response.

The expected behavior, in this case, is for the default backend use Content-Type: text/html when it fails to decode the Accept header.

I already tried adding the add_header X-Content-Type-Options nosniff always, but it did not fix the issue.

Snippet custom nginx config:

map $http_accept $extension {
  default html;
  ~application/json json;
  ~application/xml xml;

      more_set_headers  'Content-Type:$http_accept';
}

I dont understand why the response headers are in the body with 'proxy_path' option. I woul'd like to use this with OpenWRT 15.05

example :

Server: nginx/1.6.2 Date: Thu, 11 Feb 2016 14:02:17 GMT Content-Type: text/plain Content-Length: 6 Last-Modified: Fri, 05 Feb 2016 14:38:29 GMT Connection: close ETag: "56b4b3e5-6" Accept-Ranges: bytes

prout

I have no problems with the last OpenWRT sources.

Any idea ?

Thank

Adrien

I have 2 nginx frontends worked in load balancing mode. Today, around the same time on both frontends I got error: worker process exited on signal 11 Backtrace for both core dumps are similar. Backtrace are below.
