谷歌API Oauth.net核心3.1

Question

我有一个.net核心3.1 MVC web应用程序。我正在尝试开始使用一些谷歌api。我发现谷歌文档非常混乱。在官方文档中，我发现一个MVC库不支持.net核心。有人能为我指明正确的方向吗？我应该如何开始在MVC.net核心web应用程序上验证我的用户？我应该寻找一个非谷歌oauth库吗？谷歌支持我找不到的东西吗？

为了挖掘更多信息，我发现了Google.Apis.Auth.AspNetCore3。这是推荐的方法吗？有没有关于如何使用它的文档，或者我应该自己下载源代码？我完全糊涂了。

Answer 1

您可以在.NET Core 3.1中使用Google.Apis.Auth.AspNetCore3进行身份验证，这是谷歌维护和推荐的库。Google.Apis.Auth.AspNetCore3.IntegrationTest是一个很好的例子(它只是一个ASP.NET Core 3 Web应用程序(，说明了如何使用该库，并展示了它的所有功能。随意在中制造问题https://github.com/googleapis/google-api-dotnet-client如果你遇到任何问题。

Answer 2

这是谷歌分析的一个例子，如果你需要帮助为不同的api更改它，请告诉我。。

启动.cs

public class Client
{
public class Web
{
public string client_id { get; set; }
public string client_secret { get; set; }
}
public Web web { get; set; }
}

public class ClientInfo
{
public Client Client { get; set;  }
private readonly IConfiguration _configuration;
public ClientInfo(IConfiguration configuration)
{
_configuration = configuration;
Client = Load();
}
private Client Load()
{
var filePath = _configuration["TEST_WEB_CLIENT_SECRET_FILENAME"];
if (string.IsNullOrEmpty(filePath))
{
throw new InvalidOperationException(
$"Please set the TEST_WEB_CLIENT_SECRET_FILENAME environment variable before running tests.");
}
if (!File.Exists(filePath))
{
throw new InvalidOperationException(
$"Please set the TEST_WEB_CLIENT_SECRET_FILENAME environment variable before running tests.");
}
var x = File.ReadAllText(filePath);
return JsonConvert.DeserializeObject<Client>(File.ReadAllText(filePath));
}
}
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<ClientInfo>();
services.AddControllers();
services.AddAuthentication(o =>
{
// This is for challenges to go directly to the Google OpenID Handler, so there's no
// need to add an AccountController that emits challenges for Login.
o.DefaultChallengeScheme = GoogleOpenIdConnectDefaults.AuthenticationScheme;
// This is for forbids to go directly to the Google OpenID Handler, which checks if
// extra scopes are required and does automatic incremental auth.
o.DefaultForbidScheme = GoogleOpenIdConnectDefaults.AuthenticationScheme;
o.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
})
.AddCookie()
.AddGoogleOpenIdConnect(options =>
{
var clientInfo = new ClientInfo(Configuration);
options.ClientId = clientInfo.Client.web.client_id;
options.ClientSecret = clientInfo.Client.web.client_secret;
});
services.AddMvc();
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseHttpsRedirection();
app.UseRouting();

app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
}
}

具有Auth的控制器

[ApiController]
[Route("[controller]")]
public class GAAnalyticsController : ControllerBase
{

private readonly ILogger<WeatherForecastController> _logger;
public GAAnalyticsController(ILogger<WeatherForecastController> logger)
{
_logger = logger;
}
// Test showing use of incremental auth.
// This attribute states that the listed scope(s) must be authorized in the handler.
[GoogleScopedAuthorize(AnalyticsReportingService.ScopeConstants.AnalyticsReadonly)]
public async Task<GetReportsResponse> Get([FromServices] IGoogleAuthProvider auth, [FromServices] ClientInfo clientInfo)
{
var GoogleAnalyticsViewId = "78110423";
var cred = await auth.GetCredentialAsync();
var service = new  AnalyticsReportingService(new BaseClientService.Initializer
{
HttpClientInitializer = cred
});

var dateRange = new DateRange
{
StartDate = "2015-06-15",
EndDate = "2015-06-30"
};
// Create the Metrics object.
var sessions = new Metric
{
Expression = "ga:sessions",
Alias = "Sessions"
};
//Create the Dimensions object.
var browser = new Dimension
{
Name = "ga:browser"
};
// Create the ReportRequest object.
var reportRequest = new ReportRequest
{
ViewId = GoogleAnalyticsViewId,
DateRanges = new List<DateRange> {dateRange},
Dimensions = new List<Dimension> {browser},
Metrics = new List<Metric> {sessions}
};
var requests = new List<ReportRequest> {reportRequest};
// Create the GetReportsRequest object.
var getReport = new GetReportsRequest {ReportRequests = requests};
// Make the request.
var response = service.Reports.BatchGet(getReport).Execute();
return response;
}
}
