# Titanium.Network
The top level network module.
# Overview
The Network
module is used to access networking related functionality.
For TCP sockets, see Titanium.Network.Socket.TCP.
The legacy Titanium.Network.TCPSocket object is still required by the Titanium.Network.BonjourBrowser and Titanium.Network.BonjourService objects.
For all other socket needs, use Titanium.Network.Socket.TCP.
# App Transport Security
Starting with iOS 9, Apple introduced new security and compatibility guidelines for networking and connectivity, which include:
- All connections must support TLS 1.2 or greater, and use forward secrecy ciphers supported by iOS
- Certificates must use at least a SHA-256 fingerprint with either a 2048-bit or greater RSA key, or a 256-bit or greater ECC key
- Application must be compatible with IPv6 DNS64/NAT64 networks as part of App Store submissions
Because of the new requirements, Titanium disables the App Transport Security (ATS) requirements, which only includes the TLS and certificate cipher requirements, to allow all connections by default.
If you wish to re-enable ATS, add the NSAppTransportSecurity
dict to the ios plist
section
of the tiapp.xml
file, then add the NSAllowArbitraryLoads
key and set it to false
, indicating
that you want to manage your whitelisted URL's yourself.
<ti:app>
<!-- ... -->
<ios>
<plist>
<dict>
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<false/>
</dict>
</dict>
</plist>
</ios>
<!-- ... -->
</ti:app>
Note that Titanium will inject code into the plist file to whitelist appcelerator.com
subdomains,
which is needed to communicate with the Appcelerator Anayltics server. To disable the whitelist,
set the ios.whitelist.appcelerator.com
tiapp application property to false.
<ti:app>
<property name="ios.whitelist.appcelerator.com" type="bool">false</property>
</ti:app>
Listed below are other guidelines from Apple.
Avoid hard-coded IPv4 address literals
Try not to include hard-coded IPv4 address literals in your application, for example, 127.0.0.1.
Whitelist URLs
If ATS is enabled and the web service you are trying to contact does not support the new security guidelines, iOS will not allow you to connect to the service. An error will be returned in the network response stating the connection failed because it did not meet the ATS policy standards.
To allow the connection, you will need to add
a NSAppTransportSecurity
dict to the ios plist
section of the tiapp.xml
file.
In the NSAppTransportSecurity
dict, you add the NSExceptionDomains
dict to whitelist
specific domains.
For more information, see iOS Developer Library: App Transport Security (opens new window).
Example:
<ti:app>
<!-- ... -->
<ios>
<plist>
<dict>
<key>NSAppTransportSecurity</key>
<dict>
<!-- 1) Default: Disable ATS completely -->
<key>NSAllowsArbitraryLoads</key>
<true/>
<-- 2) Alternative: Define whitelisted domains -->
<key>NSExceptionDomains</key>
<dict>
<!-- Loosen security measure for www.foo.com domain -->
<key>www.foo.com</key>
<dict>
<!-- Set TLS v1.0 as the minimum TLS version -->
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.0</string>
<!-- Can use other ciphers besides forward secrecy ciphers -->
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<!-- Allow HTTP connections -->
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
</dict>
</dict>
</dict>
</dict>
</plist>
</ios>
<!-- ... -->
</ti:app>
Test IPV6 DNS64/NAT64
If you submit your application to the iTunes Store, you should setup an IPv6 DNS64/NAT64 network to test your application to verify it is compatible with IPv6.
If you are running macOS 10.11 or greater, you can use your computer to setup a local IPv6 Wi-Fi network, which requires an Internet connection not through Wi-Fi.
To create the network, from System Preferences, enable Internet sharing with NAT64 network enabled to share your Wi-Fi connection.
For detailed instructions, see Mac Developer Library: Test for IPv6 DNS64/NAT64 Compatibility (opens new window).
# Properties
# allHTTPCookies READONLY
A list of all cookies in the cookie storage.
# networkType READONLY
Network type value as a constant.
One of the NETWORK
constants defined in Titanium.Network.
# networkTypeName READONLY
Network type as a String. Returns one of NONE
, WIFI
, LAN
, MOBILE
, or UNKNOWN
.
# online READONLY
Boolean value indicating if the device is connected to the network.
The online
property is true
if the device has network access via WiFi,
LAN, or mobile/cellular network.
Note that if the device is connected to a private network without Internet access,
then this property will be true
as well. This means you cannot assume the device
has Internet access if it's connected to the network.
# remoteDeviceUUID READONLY
Remote device UUID if the device is registered with the Apple Push Notification Service, or null if it is not registered.
# remoteNotificationsEnabled READONLY
Indicates whether push notifications have been enabled using registerForPushNotifications.
# remoteNotificationTypes READONLY
Array of push notification type constants enabled for the application.
# Methods
# addHTTPCookie
Adds a cookie to the HTTP client cookie store.
On iOS, the cookie will override an existing cookie with the same name, domain and path, if any. The cookie's
expiryDate
property must be a date later than the creating date, otherwise the cookie will not persist in the
cookie storage.
On Android, any existing cookie with the same domain and name will be replaced with the new cookie. This is a bug
in BasicCookieStore
because based on RFC6265
, an existing cookie can be evicted and replaced only when it has the same cookie-name,
domain-value and path-value with the new cookie.
Parameters
Name | Type | Description |
---|---|---|
cookie | Titanium.Network.Cookie | The cookie to add |
Returns
- Type
- void
# addSystemCookie
Adds a cookie to the system cookie store.
On Android, Titanium.UI.WebView uses the system cookie store. Any existing cookie with the same domain, path and name will be replaced with the new cookie.
Parameters
