Login flow v2
While the login flow works very nice in a lot of cases there are especially on dekstop application certain hurdles. Special proxy configuration, client side certificates and the likes can cause trouble. To solve this we have come up with a second login flow that uses the users default webbrowser to authenticate. Thus ensuring that if they can login via the web they can also login in the client.
To initiate a login do an anonymous POST request
curl -X POST https://cloud.example.com/index.php/login/v2This will return a json object like
{
"poll":{
"token":"mQUYQdffOSAMJYtm8pVpkOsVqXt5hglnuSpO5EMbgJMNEPFGaiDe8OUjvrJ2WcYcBSLgqynu9jaPFvZHMl83ybMvp6aDIDARjTFIBpRWod6p32fL9LIpIStvc6k8Wrs1",
"endpoint":"https:\/\/cloud.example.com\/login\/v2\/poll"
},
"login":"https:\/\/cloud.example.com\/login\/v2\/flow\/guyjGtcKPTKCi4epIRIupIexgJ8wNInMFSfHabACRPZUkmEaWZSM54bFkFuzWksbps7jmTFQjeskLpyJXyhpHlgK8sZBn9HXLXjohIx5iXgJKdOkkZTYCzUWHlsg3YFg"
}The url in login should be opened in the default browser, this is where the user will follow the login procedure. The program should directly start polling the poll endpoint:
curl -X POST https://cloud.example.com/login/v2/poll -d "token=mQUYQdffOSAMJYtm8pVpkOsVqXt5hglnuSpO5EMbgJMNEPFGaiDe8OUjvrJ2WcYcBSLgqynu9jaPFvZHMl83ybMvp6aDIDARjTFIBpRWod6p32fL9LIpIStvc6k8Wrs1"This will return a 404 until authentication is done. Once a 200 is returned it is another json object.
{
"server":"https:\/\/cloud.example.com",
"loginName":"username",
"appPassword":"yKTVA4zgxjfivy52WqD8kW3M2pKGQr6srmUXMipRdunxjPFripJn0GMfmtNOqOolYSuJ6sCN"
}Use the server and the provided credentials to connect. Note that the 200 will only be returned once.
