Windows 10 IoT Core 以编程方式删除 WiFi 配置文件

Question

我需要从代码中删除保存的 wifi 配置文件，以便再次启用 SoftAP。根据 ms 文档，无法删除配置文件，只能断开连接。这不可能吗？

用于 wifi 的 Ms 文档 https://docs.microsoft.com/en-us/uwp/api/windows.devices.wifi.wifiadapter

设备门户API https://docs.microsoft.com/de-ch/windows/mixed-reality/device-portal-api-reference#wifi-management

这是我使用设备门户断开 wifi 的工作代码API

        // API creds
        string username = "Administrator";
        string password = "p@ssw0rd

        // API request URIs
        string apiUri = "http://192.168.1.15:8080/api/wifi/network";

        // WiFi details
        string wifiInterface = string.Empty;
        string wifiProfile = string.Empty;

        // WiFi access
        WiFiAccessStatus wifiAccess = await WiFiAdapter.RequestAccessAsync();

        if (wifiAccess == WiFiAccessStatus.Allowed)
        {
            // Get WiFi adapter
            IReadOnlyList<WiFiAdapter> wifiAdapterResult = await WiFiAdapter.FindAllAdaptersAsync();
            WiFiAdapter wifiAdapter = wifiAdapterResult[0];

            // Get conn profile / details
            ConnectionProfile profile = await wifiAdapter.NetworkAdapter.GetConnectedProfileAsync();
            wifiInterface = profile.NetworkAdapter.NetworkAdapterId.ToString();
            wifiProfile = profile.ProfileName;
        }

        // API creds
        PasswordCredential credentials = new PasswordCredential("login", username, password);

        // HttpClient filter
        HttpBaseProtocolFilter filter = new HttpBaseProtocolFilter();
        filter.CookieUsageBehavior = HttpCookieUsageBehavior.NoCookies;
        filter.CacheControl.ReadBehavior = HttpCacheReadBehavior.MostRecent;
        filter.CacheControl.WriteBehavior = HttpCacheWriteBehavior.NoCache;
        filter.ServerCredential = credentials;

        // HttpClient
        HttpClient client = new HttpClient(filter);

        apiUri = apiUri + "?interface=" + wifiInterface + "&op=disconnect" + "&createprofile=no";

        // Request
        HttpRequestMessage request = new HttpRequestMessage();
        request.Method = new HttpMethod("POST");
        request.RequestUri = new Uri(apiUri);

        // Send request
        try
        {
            // Response
            HttpResponseMessage response = await client.SendRequestAsync(request);

            // Again
            if (response.Content.ToString().Contains("Authorization Required"))
            {
                response = await client.SendRequestAsync(request);
            }
        }
        catch
        {
            // Dispose
            client.Dispose();
            filter.Dispose();
        }

但是对于删除 wifi 配置文件，我从 API 返回 404 not found。根据上面链接的 API 文档，请求应该没问题。这是我删除 wifi 配置文件的代码

        // API creds
        string username = "Administrator";
        string password = "p@ssw0rd

        // API request URIs
        string apiUri = "http://192.168.1.15:8080/api/wifi/network";

        // WiFi details
        string wifiInterface = string.Empty;
        string wifiProfile = string.Empty;

        // WiFi access
        WiFiAccessStatus wifiAccess = await WiFiAdapter.RequestAccessAsync();

        if (wifiAccess == WiFiAccessStatus.Allowed)
        {
            // Get WiFi adapter
            IReadOnlyList<WiFiAdapter> wifiAdapterResult = await WiFiAdapter.FindAllAdaptersAsync();
            WiFiAdapter wifiAdapter = wifiAdapterResult[0];

            // Get conn profile / details
            ConnectionProfile profile = await wifiAdapter.NetworkAdapter.GetConnectedProfileAsync();
            wifiInterface = profile.NetworkAdapter.NetworkAdapterId.ToString();
            wifiProfile = profile.ProfileName;
        }

        // API creds
        PasswordCredential credentials = new PasswordCredential("login", username, password);

        // HttpClient filter
        HttpBaseProtocolFilter filter = new HttpBaseProtocolFilter();
        filter.CookieUsageBehavior = HttpCookieUsageBehavior.NoCookies;
        filter.CacheControl.ReadBehavior = HttpCacheReadBehavior.MostRecent;
        filter.CacheControl.WriteBehavior = HttpCacheWriteBehavior.NoCache;
        filter.ServerCredential = credentials;

        // HttpClient
        HttpClient client = new HttpClient(filter);

        apiUri = apiUri + "?interface=" + wifiInterface + "&profile=" + wifiProfile;

        // Request
        HttpRequestMessage request = new HttpRequestMessage();
        request.Method = new HttpMethod("DELETE")
        request.RequestUri = new Uri(apiUri);

        // Send request
        try
        {
            // Response
            HttpResponseMessage response = await client.SendRequestAsync(request);

            // Again
            if (response.Content.ToString().Contains("Authorization Required"))
            {
                response = await client.SendRequestAsync(request);
            }
        }
        catch
        {
            // Dispose
            client.Dispose();
            filter.Dispose();
        }

要解决这个问题，自 build 17763 以来，有一种新方法可以直接从可用代码中删除 WiFi 配置文件

bool canDelete = wifiProfile.CanDelete;
if (canDelete)
{
     ConnectionProfileDeleteStatus deleteStatus = await wifiProfile.TryDeleteAsync();
}

Answer 1

您可以从您的程序中调用 netsh。

netsh wlan delete <profile name> 应该能让你到达那里。

Answer 2

经过几个小时的努力，终于找到了解决办法！对于那些有兴趣的人，你必须调用 "run command" API，它允许你运行某些 windows 命令

string deleteCommand = "netsh wlan delete profile name=*";

string cmdApi = string.Format("http://192.168.1.15:8080/api/iot/processmanagement/runcommand?command={0}&runasdefaultaccount={1}", GetBase64String(deleteCommand), GetBase64String("no"));

这里真正需要注意的是，你必须将命令编码为base64字符串，否则将无法运行！

private string GetBase64String(string stringToConvert)
{
    return Convert.ToBase64String(Encoding.UTF8.GetBytes(stringToConvert));
}

使用此代码，我终于可以删除某些 wifi 配置文件，或者在上面的示例中，删除每个已保存的配置文件。

非常感谢安迪找到这个。我之前是用命令行来做的，但这确实有效。我围绕它添加了一些支持代码，以帮助其他人解决我遇到的一些问题，例如获取、删除或 post。如果它有效，那么我将重新启动 IoT 以返回入职模式。也许有人会觉得这有帮助。

可能需要也可能不需要以管理员身份登录门户，但我就是这样做的。 if (interfaceGUID != null) 由先前的 Api 请求分配，可以删除以进行测试。

private string password = "yourpassword";
private string localhost = "127.0.0.1";                              
private async Task DeleteProfile()
    {
        try
        {
            using (HttpClient client = new HttpClient())
            {
                if (interfaceGUID != null)
                {
                    string deleteCommand = "netsh wlan delete profile name=*";
                    using (HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, string.Format("http://{0}:8080/api/iot/processmanagement/runcommand?command={1}&runasdefaultaccount={2}", localhost, Convert.ToBase64String(Encoding.UTF8.GetBytes(deleteCommand)), Convert.ToBase64String(Encoding.UTF8.GetBytes("no")))))
                    {
                        request.Headers.Authorization = CreateBasicCredentials("Administrator");
                        using (HttpResponseMessage response = await client.SendAsync(request))
                        {
                            if (response.IsSuccessStatusCode == true)
                            {
                                 ShutdownManager.BeginShutdown(Windows.System.ShutdownKind.Restart, TimeSpan.FromSeconds(1));
                            }
                            else
                            {
                                Debug.WriteLine("Could not delete the profiles. " + response.ReasonPhrase.ToString());
                            }
                        }

                    }
                }
                client.Dispose();
            }
        }
        catch (Exception ex)
        {
            Debug.WriteLine("Could not delete the profiles. " + ex.InnerException.ToString());
        }
    }
private AuthenticationHeaderValue CreateBasicCredentials(string userName)
    {
        string toEncode = userName + ":" + password;
        Encoding encoding = Encoding.GetEncoding("iso-8859-1");
        byte[] toBase64 = encoding.GetBytes(toEncode);
        string parameter = Convert.ToBase64String(toBase64);
        return new AuthenticationHeaderValue("Basic", parameter);
    }

Answer 4

最近在 Windows 设备门户 API 上工作，遇到了这个 post。您的代码收到 404 响应的原因是因为在 API URI 中，&profile= 需要一个 Base64 值而不是您正在使用的文本字符串。将配置文件名称编码为 Base64 后，它应该可以工作。

我相信这在 MS 的设备门户文档中没有明确说明，因为我只是在删除 WIFI 配置文件时使用 Web 浏览器调试器检查 Windows 设备门户网页才发现这一点。
