我正在使用Google的Place API来自动填充用户输入的城市名称(网页).加载API时将语言(pt-BR)作为参数传递,文本框正在以葡萄牙语正确填充,但是当执行方法getPlace()时,它将以英语返回结果(country和administrative_area_level_1).

我不确定问题是Google API,它们是葡萄牙语的翻译还是我错过的.我试图加载它通过西班牙语(es),英语(en)和意大利语(它)作为语言的参数并按预期工作.

这是我加载的方式:

<script src="https://maps.googleapis.com/maps/api/js?key=[myapikey]&signed_in=true&libraries=places&callback=initAutocomplete&language=pt-BR" async defer></script>

...以及我如何根据Google的示例代码获得结果:

// Get the place details from the autocomplete object.
var place = autocomplete.getPlace();

我也使用反向地理编码API传递place_id,问题是相同的(C#代码).

    var apikey = "[myserverapikey]";
    var requestUri = string.Format("https://maps.googleapis.com/maps/api/geocode/json?place_id={0}&key={1}", place_id, apikey);

    var idiomas = new string[] {"pt-BR", "es", "en-us", "it"};

    string responseContent = string.Empty;
    foreach (var idioma in idiomas)
    {
        HttpWebRequest request = WebRequest.Create(requestUri) as HttpWebRequest;
        request.Headers.Add(HttpRequestHeader.AcceptLanguage, idioma);
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;
        StreamReader reader = new StreamReader(response.GetResponseStream());

        var jsontext = reader.ReadToEnd().Trim();

        responseContent += jsontext;

        var …

我正在尝试使用Owin在Google.Apis请求中提供的AccessToken,但我收到异常System.InvalidOperationException(附加信息:访问令牌已过期但我们无法刷新它).

我的Google身份验证配置正常,我可以使用它成功登录我的应用程序.我将context.AccessToken存储为身份验证回调中的声明(GoogleOAuth2AuthenticationProvider的OnAuthenticated"event").

我的Startup.Auth.cs配置(app.UseGoogleAuthentication(ConfigureGooglePlus()))

private GoogleOAuth2AuthenticationOptions ConfigureGooglePlus()
{
var goolePlusOptions = new GoogleOAuth2AuthenticationOptions()
{
    ClientId = "Xxxxxxx.apps.googleusercontent.com",
    ClientSecret = "YYYYYYzzzzzz",
    Provider = new GoogleOAuth2AuthenticationProvider()
    {
        OnAuthenticated = context =>
        {
            context.Identity.AddClaim(new System.Security.Claims.Claim("Google_AccessToken", context.AccessToken));
            return Task.FromResult(0);
        }
    },
    SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie
};

goolePlusOptions.Scope.Add("https://www.googleapis.com/auth/plus.login");
goolePlusOptions.Scope.Add("https://www.googleapis.com/auth/userinfo.email");

return goolePlusOptions;

}

抛出异常的代码(Execute()方法)

var externalIdentity = await AuthenticationManager.GetExternalIdentityAsync(DefaultAuthenticationTypes.ExternalCookie);

var accessTokenClaim = externalIdentity.FindAll(loginProvider + "_AccessToken").First();

var secrets = new ClientSecrets()
{
    ClientId = "Xxxxxxx.apps.googleusercontent.com",
    ClientSecret = "YYYYYYzzzzzz"
};

IAuthorizationCodeFlow flow =
    new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
    {
        ClientSecrets = …

我将我的ASP.NET MVC Web应用程序从成员身份转移到身份验证,因为我无法再在LinkedIn上进行身份验证.

Facebook身份验证仍然正常,但LinkedIn总是在GetExternalLoginInfo调用后返回null loginInfo.

对于LinkedIn我正在使用Owin LinkedIn提供程序:用于.NET的LinkedIn API.我也试图跟随杰里·佩尔泽的这篇文章不成功.

Application调用执行ExecuteResult方法的ExternalLogin Action并回调ExternalLoginCallback(在我允许访问应用程序之后).如前所述,方法AuthenticationManager.GetExternalLoginInfoAsync()始终返回null loginInfo.

我检查了LinkedIn中的应用程序设置,一切似乎都没问题.

行动!我差点忘了说LinkedIn正在返回带有一般错误消息的URL:"GET/Account/ExternalLoginCallback？error = access_denied HTTP/1.1"

我可以使用DotNetOpenAuth.Clients(托管的github)进行身份验证,但我想使用Identity.

Startup.Auth.cs

var linkedInOptions = new LinkedInAuthenticationOptions();
        linkedInOptions.ClientId = "Xxxxx";
        linkedInOptions.ClientSecret = "Yyyyyyy";

        linkedInOptions.Scope.Add("r_fullprofile");

        linkedInOptions.Provider = new LinkedInAuthenticationProvider()
        {
            OnAuthenticated = async context =>
            {
                context.Identity.AddClaim(new System.Security.Claims.Claim("LinkedIn_AccessToken", context.AccessToken));
            }
        };

        linkedInOptions.SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie;

        app.UseLinkedInAuthentication(linkedInOptions);

ExternalLogin

public ActionResult ExternalLogin(string provider, string returnUrl)
    {
        // Request a redirect to the external login provider
        return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl …
