Commandline option|Meaning
---|---
-d <loglevel>|Debug verbosity in decimal, eg, -d15
-l| Connect to https://localhost:7681 and accept selfsigned cert
--h1|Specify http/1.1 only using ALPN, rejects h2 even if server supports it
client: LCCSCF_ALLOW_INSECURE AG add options the minimal http client related to this
2019-09-18 10:00:59 +01:00
--server <name>|set server name to connect to
-k|Apply tls option LCCSCF_ALLOW_INSECURE
-j|Apply tls option LCCSCF_ALLOW_SELFSIGNED
-m|Apply tls option LCCSCF_SKIP_SERVER_CERT_HOSTNAME_CHECK
-e|Apply tls option LCCSCF_ALLOW_EXPIRED
lws_validity: unified connection validity tracking Refactor everything around ping / pong handling in ws and h2, so there is instead a protocol-independent validity lws_sul tracking how long it has been since the last exchange that confirms the operation of the network connection in both directions. Clean out periodic role callback and replace the last two role users with discrete lws_sul for each pt.
2019-09-18 13:09:32 +01:00
-v|Connection validity use 3s / 10s instead of default 5m / 5m10s

http client basic auth add helper and example
2019-12-22 04:58:44 +00:00
You can also test the client Basic Auth support against the http-server/minimal-http-server-basicauth
example. In one console window run the server and in the other
```
$ lws-minimal-http-client -l --nossl --path /secret/index.html --user user --password password
```
The Basic Auth credentials for the test server are literally username "user" and password "password".
