如何以及如何设置为Android WifiConfiguration.preSharedKey以连接到WPA2 PSK WiFi网络

Question

在Android 1.5中（也在1.6中）

如何从代码添加访问点？

给定的支持WPA2的访问点。这是我的代码段。

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
// This is must be quoted according to the documentation 
// http://developer.android.com/reference/android/net/wifi/WifiConfiguration.html#SSID
wc.SSID = "\"SSIDName\"";
wc.preSharedKey  = "password";
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;        
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean b = wifi.enableNetwork(res, true);        
Log.d("WifiPreference", "enableNetwork returned " + b );

此代码失败，因为出现在LogCat中

01-26 16：44：13.550：错误/ wpa_supplicant（2032）：第0行：无效的PSK’密码’。

我确定这是密码，其余所有参数都是正确的。我想念什么？

我悲伤的原因在此文档问题中

虽然这里的文档指出

“与WPA-PSK一起使用的预共享密钥。读取此密钥的值时，不返回实际密钥，如果密钥具有值，则仅返回“ *”，否则返回空字符串。”

是正确的，但是非常重要的是它 没有说的 是Linux命令的以太64字节哈希结果

wpa_passphrase <ssid> [passphrase]

或 双 点访问接入点的密码 ！

因此，如果Access Point的PSK是 “ example” ，则必须像这样在Java中传递它

WifiConfiguration myWiFiConfig = new WifiConfiguration();
...
myWiFiConfig.preSharedKey = "\"example\"";
...

要么

myWiFiConfig.preSharedKey = "0a0b0f62170ecc5bcf721b6ff170b8b560101b5d56b00a26abec217e0bb4aa1f";

对于所有其他人，您都会发现正确的方法是：

照原样复制并粘贴，并节省您已经花了半天的时间（特别感谢Reflog）

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = "\"SSIDName\"";
wc.preSharedKey  = "\"password\"";
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;        
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean b = wifi.enableNetwork(res, true);        
Log.d("WifiPreference", "enableNetwork returned " + b );
