RPI: Remote web Inspector not working

[deeps8us]

Trying to use remote web inspector in rpi. But getting error.

westeros --renderer libwesteros_render_gl.so.0.0.0 --framerate 60 --display main0 &
export WEBKIT_INSPECTOR_SERVER=${WEBKIT_INSPECTOR_SERVER:-':::9224'}
/usr/bin/WPELauncher http:///wizardkit/ui/guide.html &

From browser: launch
http://<board_ip>:9224/

Getting the error:

Inspectable web views

None found, make sure that you have set the developerExtrasEnabled preference property on your WebView.

@deeps8us The WEBKIT_INSPECTOR_SERVER should have an valid address to bind to. Can you try setting it to WEBKIT_INSPECTOR_SERVER=0.0.0.0:9224? Also, if you are using a modern enought branch, you will need to access inspector://<board-ip>:9224 from the browser instead of http://<board-ip>:9224. Also, you will need a WebKit-based browser like GNOME Web or Midori.

Same issue after setting WEBKIT_INSPECTOR_SERVER=0.0.0.0:9224 and also with Midori

@deeps8us Which version of WPE WebKit are you using? It looks like you are using WpeLauncher. Is that so? Re-reading its code I see that it does not enable the developer extras, which is needed for the remote inspector to work — there is no call to WKPreferencesSetDeveloperExtrasEnabled(), you may need patch it with a change like the one suggested in WebPlatformForEmbedded/WPEWebKitLauncher#5

hi @aperezdc we enabled "WKPreferencesSetDeveloperExtrasEnabled" in our launcher code, but it didn't worked for us. We are still facing same error "None found, make sure that you have set the developerExtrasEnabled preference property on your WebView" on browser.

hi @albertd we tried on 9888 port as well but still observes the same behaviour.

Is this WKPreferencesSetDeveloperExtrasEnabled needs to be enable from browser end?? (or) can we enable on platform directly.

I'm running WPELauncher with the newer WPEWebkit (wpe-20170728), specifically: 371d4b0 and c04a067 and I don't have an inspector either.

WPELauncher binds just fine to 9998, as export WEBKIT_INSPECTOR_SERVER=0.0.0.0:9998 is set by the default /usr/bin/wpe script, but both over http:// (Chromium/Midori) and inspector:// (Midori) there's only an empty response I don't even see that error OP mentioned.

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:9998            0.0.0.0:*               LISTEN      20424/WPELauncher

I have a warning when WPELauncher starts, but otherwise works fine, not sure if it's related.

** (process:19966): WARNING **: Error loading the injected bundle (/usr/lib/libWPEInjectedBundle.so): /usr/lib/libWPEInjectedBundle.so: undefined symbol: _ZN6WebKit22WebKitExtensionManager10initializeEPNS_14InjectedBundleEPN3API6ObjectE
[WPELauncher] Hello InjectedBundle ...

If I follow this thread correctly, I'll need the patch from @aperezdc and that should be it, or is there anything else I need to be aware of when "downgrading" to WPELauncher?

Thanks, that works indeed.

Hi @albertd,

         I tried with enabling  WEBKIT_INSPECTOR_SERVER and  WEBKIT_LEGACY_INSPECTOR_SERVER with 9222 and 9998 ports. But i am getting raw data representation on my browser when i am accessing wpe-inspector page. I have used Google chrome and mozilla firefox as well for this.

Please see the raw data in my attachment.

Could you please let us what we are missing here.

[aperezdc]

@Trinath402 It looks like the device where WPELauncher is running is missing the shared-mime-info package, which the inspector server uses (through GLib) to determine the Content-Type it has to return in its responses. Could you please try to add it to your build and try again?

[Trinath402]

Thank you @aperezdc it's worked for me. After including this package in our image i am getting the response properly.
