Agent hierarchy
===============
Service unique name
Interface net.connman.Agent
Object path freely definable
Methods void Release()
This method gets called when the service daemon
unregisters the agent. An agent can use it to do
cleanup tasks. There is no need to unregister the
agent, because when this method gets called it has
already been unregistered.
void ReportError(object service, string error)
This method gets called when an error has to be
reported to the user.
A special return value can be used to trigger a
retry of the failed transaction.
Possible Errors: net.connman.Agent.Error.Retry
void ReportPeerError(object peer, string error)
This method gets called when an error has to be
reported to the user about a peer connection.
A special return value can be used to trigger a
retry of the failed transaction.
Possible Errors: net.connman.Agent.Error.Retry
void RequestBrowser(object service, string url)
This method gets called when it is required
to ask the user to open a website to procceed
with login handling.
This can happen if connected to a hotspot portal
page without WISPr support.
Possible Errors: net.connman.Agent.Error.Canceled
dict RequestInput(object service, dict fields)
This method gets called when trying to connect to
a service and some extra input is required. For
example a passphrase or the name of a hidden network.
The return value should be a dictionary where the
keys are the field names and the values are the
actual fields. Alternatively an error indicating that
the request got canceled can be returned.
Most common return field names are "Name" and of
course "Passphrase".
The dictionary arguments contains field names with
their input parameters.
In case of WISPr credentials requests and if the user
prefers to login through the browser by himself, agent
will have to return a LaunchBrowser error (see below).
Possible Errors: net.connman.Agent.Error.Canceled
net.connman.Agent.Error.LaunchBrowser
dict RequestPeerAuthorization(object peer, dict fields) [experimental]
This method gets called when trying to connect to a
peer or when an incoming peer connection is requested,
for which some extra input is required. In this case,
it will only deal with WPS input as well as accepting
or rejecting an incoming connection.
The return value should be a dictionary where the
keys are the field names and the values are the
actual fields. Alternatively an error indicating that
the request got canceled or rejected can be returned.
The dictionary arguments contains field names with
their input parameters.
Possible Errors: net.connman.Agent.Error.Canceled
net.connman.Agent.Error.Rejected
void Cancel()
This method gets called to indicate that the agent
request failed before a reply was returned.
Fields string Name
The name of a network. This field will be requested
when trying to connect to a hidden network.
array{byte} SSID
This field is an alternative to "Name" for WiFi
networks and can be used to return the exact binary
representation of a network name.
Normally returning the "Name" field is the better
option here.
string Identity
Identity (username) for EAP authentication methods.
string Passphrase
The passphrase for authentication. For example a WEP
key, a PSK passphrase or a passphrase for EAP
authentication methods.
string PreviousPassphrase
The previous passphrase successfully saved, i.e.
which led to a successfull connection. This field is
provided as an informational argument when connecting
with it does not work anymore, for instance when it
has been changed on the AP. Such argument appears when
a RequestInput is raised after a retry. In case of WPS
association through PIN method: when retrying, the
previous wpspin will be provided.
string WPS
This field requests the use of WPS to get associated.
This is an alternate choice against Passphrase when
requested service supports WPS. The reply can contain
either empty pin, if user wants to use push-button
method, or a pin code if user wants to use the pin
method.
In case of a RequestPeerAuthorization, this field will
be set as mandatory.
string Username
Username for WISPr authentication. This field will be
requested when connecting to a WISPr-enabled hotspot.
string Password
Password for WISPr authentication. This field will be
requested when connecting to a WISPr-enabled hotspot.
Arguments string Type
Contains the type of a field. For example "psk", "wep"
"passphrase", "response", "ssid", "wpspin" or plain
"string".
string Requirement
Contains the requirement option. Valid values are
"mandatory", "optional", "alternate" or
"informational".
The "alternate" value specifies that this field can be
returned as an alternative to another one. An example
would be the network name or SSID.
All "mandatory" fields must be returned, while the
"optional" ones can be returned if available.
Nothing needs to be returned for "informational", as it
is here only to provide an information. A value is
attached to it.
array{string} Alternates
Contains the list of alternate field names this
field can be represented by.
string Value
Contains data as a string, relatively to an
"informational" argument.
Examples Requesting a passphrase for WPA2 network
RequestInput("/service1",
{ "Passphrase" : { "Type" : "psk",
"Requirement" : "mandatory"
}
}
==> { "Passphrase" : "secret123" }
Requesting a passphrase after an error on the previous one:
RequestInput("/service1",
{ "Passphrase" : { "Type" : "psk",
"Requirement" : "mandatory"
},
"PreviousPassphrase" :
{ "Type" : "psk",
"Requirement : "informational",
"Value" : "secret123"
}
}
Requesting name for hidden network
RequestInput("/service2",
{ "Name" : { "Type" : "string",
"Requirement" : "mandatory",
"Alternates" : [ "SSID" ]
},
"SSID" : { "Type" : "ssid",
"Requirement" : "alternate"
}
}
==> { "Name" : "My hidden network" }
Requesting a passphrase for a WPA2 network with WPS alternative:
RequestInput("/service3",
{ "Passphrase" : { "Type" : "psk",
"Requirement" : "mandatory",
"Alternates" : [ "WPS" ]
},
"WPS" : { "Type" : "wpspin",
"Requirement" : "alternate"
}
}
==> { "WPS" : "123456" }
Requesting a passphrase for a WPA2 network with WPS alternative
after an error on the previous one:
RequestInput("/service3",

"Requirement" : "mandatory",
"Alternates" : [ "WPS" ]
},

"Requirement" : "alternate"
}

"Value" : "123456"
}

"Requirement" : "mandatory"
}
}
==> { "Identity" : "alice", "Passphrase": "secret123" }
