Question

我正在我的phonegap应用中运行这段代码。代码执行完全没有错误，但有一个问题，无论何时它总是显示UNKNOWN CONNECTION，我在设备或模拟器上运行应用程序，为什么会出现网络类型始终未知的原因。

function checkConnection() {
 var networkState = navigator.connection.type;
    var states = {};
    states[navigator.connection.UNKNOWN]  = 'Unknown Connection';
    states[navigator.connection.ETHERNET] = 'Ethernet connection';
    states[navigator.connection.WIFI]     = 'WiFi connection';
    states[navigator.connection.CELL_2G]  = 'Cell 2G connection';
    states[navigator.connection.CELL_3G]  = 'Cell 3G connection';
    states[navigator.connection.CELL_4G]  = 'Cell 4G connection';
    states[navigator.connection.NONE]     = 'No network connection';

    alert('Connection type: ' + states[networkState]);
}
checkConnection();

Answer 1

你的代码没有错误。你在onDeviceReady（）上调用了checkConnection（）方法。另外请检查link 将您的网络状态设置为;

var networkState = navigator.network.connection.type;

请试一试。

function checkConnection() {
var networkState = navigator.network.connection.type;

var states = {};
states[Connection.UNKNOWN]  = 'Unknown connection';
states[Connection.ETHERNET] = 'Ethernet connection';
states[Connection.WIFI]     = 'WiFi connection';
states[Connection.CELL_2G]  = 'Cell 2G connection';
states[Connection.CELL_3G]  = 'Cell 3G connection';
states[Connection.CELL_4G]  = 'Cell 4G connection';
states[Connection.NONE]     = 'No network connection';

alert('Connection type: ' + states[networkState]);
}
 checkConnection();

另外请检查您是否添加了不同平台所需的权限。

Answer 2

我在“config.xml”中更改了功能配置时解决了同样的问题。如果您正在尝试使用Android设备，请

<feature name="NetworkStatus">
    <param name="android-package" value="org.apache.cordova.NetworkManager" />
</feature>

尝试

<feature name="NetworkStatus">
    <param name="android-package" value="org.apache.cordova.networkinformation.NetworkManager" />
</feature>

（在“NetworkManager”之前添加“ networkinformation。”）

Answer 3

This comment适合我。

在cordova-plugin的文档中，您必须确保查看正确版本的cordova。示例：对于Cordova 2.5.0

<plugin name="NetworkStatus" value="org.apache.cordova.NetworkManager" />

Cordova 3.3.0：

<feature name="NetworkStatus">
  <param name="android-package" value="org.apache.cordova.networkinformation.NetworkManager" />
</feature>
