具体的代码路径可能因不同的开发环境而有所不同,以下是一种通用的代码路径。
1. 获取当前Wifi网络信息,可以使用以下代码:
```
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
String ssid = wifiInfo.getSSID();
String bssid = wifiInfo.getBSSID();
```
2. 获取当前系统代理设置,可以使用以下代码:
```
String proxyHost = System.getProperty("http.proxyHost");
int proxyPort = Integer.parseInt(System.getProperty("http.proxyPort"));
```
3. 断开当前Wifi连接,可以使用以下代码:
```
wifiManager.disconnect();
```
4. 等待一段时间,可以使用以下代码:
```
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
```
5. 扫描可用的Wifi网络列表,可以使用以下代码:
```
List<ScanResult> scanResults = wifiManager.getScanResults();
for (ScanResult scanResult : scanResults) {
if (scanResult.SSID.equals(ssid) && scanResult.BSSID.equals(bssid)) {
WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.SSID = "\"" + ssid + "\"";
wifiConfiguration.BSSID = bssid;
wifiConfiguration.preSharedKey = "\"" + password + "\"";
wifiConfiguration.hiddenSSID = false;
wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int netId = wifiManager.addNetwork(wifiConfiguration);
wifiManager.enableNetwork(netId, true);
break;
}
}
```
6. 检查当前系统代理设置是否为PAC代理,可以使用以下代码:
```
if (proxyHost != null && proxyHost.contains("pac")) {
String pacUrl = "http://" + proxyHost + ":" + proxyPort + "/proxy.pac";
}
```
7. 重新设置PAC代理地址,可以使用以下代码:
```
String proxySettings = Settings.System.getString(context.getContentResolver(), Settings.System.HTTP_PROXY);
if (proxySettings != null && proxySettings.contains("pac")) {
proxySettings = proxySettings.replaceFirst("http=.*?(?=\\s|$)", "http=" + pacUrl);
Settings.System.putString(context.getContentResolver(), Settings.System.HTTP_PROXY, proxySettings);
}
```
8. 测试PAC代理是否可用,可以使用以下代码:
```
URL url = new URL("http://www.example.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
connection.connect();
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
// PAC代理可用
} else {
// PAC代理不可用
}
```
需要注意的是,以上代码仅供参考,具体实现需要根据实际情况进行修改。同时,为了保证代码的安全性和稳定性,建议在使用时谨慎考虑。
