Unsupported protocol #2

Closed mingweiLIU closed 1 year ago

mingweiLIU commented 1 year ago

Hi, I built vsgCS under windows with visual studio 2022, and when I run the demo worldviewer with my ion token file, there comes out with no earth but blue empty space, the errors were: [TilesetContentManager.cpp] An unexpected error occurs when loading tile: Unsupported protocol, Warning: Error while creating tile provider: Unsupported protocol.

Hi, Thanks for giving vsgCs a try! What world file were you trying to load? I have not seen this error, but I would guess that there's a problem with your installation of libcurl. How did you install libcurl? I used vcpkg, and I have installed:

curl:x64-windows
curl[schannel]:x64-windows
curl[ssl]:x64-windows
curl[sspi]:x64-windows
curl[winssl]:x64-windows

Do you think you have a good network connection to cesium.com? We might need to make some timeout values user-configurable.

Yeah, I built all the 3rd party libs vsgCs needs （such complicated work though）including the curl, and the network connecting to cesium.com is ok since I apply the token from the website. Your answer suggests to me that there may be some network problems that should be checked.

You've left issue open, so do you think that the network is not the problem? Are you accessing the network through a proxy? If so, it's possible that we need to do some additional configuration in libcurl. A good test would be to run the vsgpagedlod example from vsgExamples, which also uses libcurl.

There were some errors with libcurl and the example come with “SSL peer certificate or SSH remote key was not OK”, I finally fixed it by adding curl_easy_setopt(curl,CURLOPT_SSL_VERIFYPEER,false) in UrlAssetResponse::setCallbacks.

Glad you got it working! I can imagine what you did, but if you make a pull request then I will merge it in.
