ios - Microsoft for Xamarin Forms 的 active-directory-xamarin-native-v2 示例项目在 iOS 中不起作用

Question

我正在处理 office365 身份验证，从 github 获取代码，对于 android 构建它工作正常，但在 iOS 中没有从 office365 获取数据响应（令牌）。

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
    }

    async void OnSignInSignOut(object sender, EventArgs e)
    {
        AuthenticationResult authResult = null;
        IEnumerable<IAccount> accounts = await App.PCA.GetAccountsAsync();
        try
        {
            if (btnSignInSignOut.Text == "Sign in")
            {
                // let's see if we have a user in our belly already
                try
                {
                    IAccount firstAccount = accounts.FirstOrDefault();
                    authResult = await App.PCA.AcquireTokenSilent(App.Scopes, firstAccount)
                                          .ExecuteAsync();
                    await RefreshUserDataAsync(authResult.AccessToken).ConfigureAwait(false);
                    Device.BeginInvokeOnMainThread(() => { btnSignInSignOut.Text = "Sign out"; });
                }
                catch (MsalUiRequiredException ex)
                {
                    try
                    {

                        authResult = await App.PCA.AcquireTokenInteractive(App.Scopes)
                                                  .WithParentActivityOrWindow(App.ParentWindow)
                                                  .ExecuteAsync();

                        await RefreshUserDataAsync(authResult.AccessToken);
                        Device.BeginInvokeOnMainThread(() => { btnSignInSignOut.Text = "Sign out"; });
                    }
                    catch(Exception ex2)
                    {
                        slUser.IsVisible = true;
                    }
                }
            }
            else
            {
                while (accounts.Any())
                {
                    await App.PCA.RemoveAsync(accounts.FirstOrDefault());
                    accounts = await App.PCA.GetAccountsAsync();
                }

                slUser.IsVisible = false;
                Device.BeginInvokeOnMainThread(() => { btnSignInSignOut.Text = "Sign in"; });
            }
        }
        catch (Exception ex)
        {

        }
    }

    public async Task RefreshUserDataAsync(string token)
    {
        //get data from API
        slUser.IsVisible = true;
        HttpClient client = new HttpClient();
        HttpRequestMessage message = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/me");
        message.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("bearer", token);
        HttpResponseMessage response = await client.SendAsync(message);
        string responseString = await response.Content.ReadAsStringAsync();
        if (response.IsSuccessStatusCode)
        {
            JObject user = JObject.Parse(responseString);

            slUser.IsVisible = true;

            Device.BeginInvokeOnMainThread(() =>
            {

                lblDisplayName.Text = user["displayName"].ToString();
                lblGivenName.Text = user["givenName"].ToString();
                lblId.Text = user["id"].ToString();
                lblSurname.Text = user["surname"].ToString();
                lblUserPrincipalName.Text = user["userPrincipalName"].ToString();

                // just in case
                btnSignInSignOut.Text = "Sign out";
            });
        }
        else
        {
            await DisplayAlert("Something went wrong with the API call", responseString, "Dismiss");
        }
    }
}
}

我应该得到与 android build 相同的内容，但在 iOS 中没有从 office365 服务器获取令牌，似乎是证书问题，我发现下面的行需要遵循，以便在 iOS 中工作

此外，为了使令牌缓存工作并让 AcquireTokenSilentAsync 工作，必须遵循多个步骤：

1) 在您的 Entitlements.plist 文件中启用钥匙串访问，并在钥匙串组中指定您的捆绑标识符。

2) 在您的项目选项中，在 iOS Bundle Signing 视图中，为自定义权利字段选择您的 Entitlements.plist 文件。

3) 签署证书时，确保 XCode 使用相同的 Apple ID。

下面是 Entitlements.plist 文件详细信息 - 我正在使用的钥匙串访问组 $(AppIdentifierPrefix)com.oauth.office365 其中 com.oauth.office365 是我的包标识符
