Android的 - 看看密码的wifi是正确的 [英] Android - see if password to wifi was correct

问题描述

我打算做如果某无线网络使用共同的密码，检查应用程序。我最常用的密码列表，但以下功能：

I plan to make an app that checks if a certain wifi network uses common password. I have a list of most common passwords, but the following function:

public boolean connectTo(String psKey){
    WifiConfiguration wc = new WifiConfiguration();
    wc.SSID = "\"" + dbw.getSsid() + "\"";
    wc.preSharedKey  = "\"" + psKey + "\"";

    wc.status = WifiConfiguration.Status.ENABLED;   
    wc = configureCapabs(wc, dbw.getCapability());

    int res = wifi.addNetwork(wc);
    Toast.makeText(this, "add Network returned " + res , Toast.LENGTH_SHORT).show();
    boolean b = wifi.enableNetwork(res, true);        
    Toast.makeText(this, "enableNetwork returned " + b , Toast.LENGTH_SHORT).show();
    if(!b) return false;
    boolean fin = /*b ? wifi.reassociate() : */wifi.reconnect();
    return fin;
}

返回true，即使密码是不正确的。是否有检查，如果我试图与登录密码被接受或拒绝的方式？

it returns true, even if the password was incorrect. Is there a way of checking if the password that I tried to log in with was accepted or rejected?

推荐答案

正在使用重新连接（） / 重新关联（） WiFiManager 的方法来检查天气或没有成功连接，但布尔值，他们返回意味着别的东西。返回值只告诉你开始给定操作的结果。这是因为关联并连接到WiFi网络需要时间。这些方法但是会立即返回，并不会阻止。连接或与网络相关联的实际任务是在后台异步完成

You are using the reconnect() / reassociate() methods of WiFiManager to check weather or not the connection succeeded but the boolean value that they return means something else. The returned value only tells you about the result of STARTING a given operation. This is because associating and connecting to a WiFi network takes time. These methods however will return instantly and will not block. The actual task of connecting or associating with the network is done asynchronously in the background.

您可以监控的是与通过监听到一个特定的系统范围内的广播WiFi连接发生的事情：

You can monitor the what is happening with the WiFi connection by listening to a specific system wide broadcast:

<action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
<action android:name="android.net.wifi.STATE_CHANGE"/>
