Can't see imagery

[VincentROBBE]

Hi,

Thanks and congratulations for your job ! I am trying to use the plugin with QGIS 3.2, windows 10 but i don't see imagery. Il seems "Cross origin requests are not supported.", see printscreen

Bests !

I have the same issue, Windows 7 64-bit with QGIS 3.2.

It may be a CORS issue: https://www.thepolyglotdeveloper.com/2014/08/bypass-cors-errors-testing-apis-locally/

Hi! I’ve got exactly the same issue – QGIS 3.2.1/Windows 10: [cid:image001.jpg@01D43A1B.CFE8DE60] /Toomas

Cross Origin Requests are available when the remote serves the resource with Access-Control-Allow-Origin: * in http response header In our case, the plugin, reads the browser page in a QWebView (the QT5 web browser widget ) from a local file, that, for security reason should not have a response header (ther is no http server) as you can see from the following image Normally, in desktop browsers no header directive results in no CORS and the policy should be activated by an extension. The plugin uses QT5 Webkit as browser and I can't find any documentation for enabling CORS for local files, but in most QGIS systems, this is not a problem, and executing the html browser page from local file does not throw exception (but I don't know the reason why) So It should suffits to load html page from a public server for having CORS enabled, so I enabled github pages for this repository and branched the viewer code to point the QWebView widget, getting the following http response: Now you can test downloading https://raw.githubusercontent.com/enricofer/go2mapillary/cors/mapillary_viewer.py, substituting the original file in the go2mapillary plugin directory and reloading the plugin to see if imagery is visible. Please check it and let me know

Thanks all for submissions.

[cbeddow]

What should be the plugin directory? I am having trouble finding it

[cbeddow]

Success for me too, amazing! Thanks @enricofer !

[iamnunocaldeira]

perfect, finally works on my side with this fix. thanks enricofer

Hi @enricofer Many thanks for the plugin.

Note that I was also affected by this issue. The green Mapillary layers loaded fine. But I got no images - the panel remained black. After replacing mapillary_viewer.py - everything worked as expected.

Again - many thanks for this useful plugin! Andreas

[enricofer]

I just submitted a new release on repository: http://plugins.qgis.org/plugins/go2mapillary/

[andreasneumann]

Excellent - thanks @enricofer

BTW: I learned about you plugin at the FOSS4G conference in Dar es Salaam. There was a presentation from a Mapillary representative.

[enricofer]

I'm happy to know you find it interesting. @cbeddow recently told me about his presentation at foss4g 2018 and I delegate him to show the plugin Mapillary built a wide tools ecosystem around his imagery service and most of the plugin features come from their vision. feel free to submit me any issue report or enhancement request.
