假设我有一个通用的LocationController,BatteryController,AppSateController等inilizations mehods的单身人士...

它们应该在onResume中而不是OnCreate,因为OnCreate会在每次旋转时被调用,每次它都变为foregroud等等吗？

我使用Core 2.0创建了一个web api,并且在执行跨域调用时启用了cors,接收到以下错误:"请求的资源上没有'Access-Control-Allow-Origin'标头."

以下是我在startup.cs中的配置:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddLogging();
        services.AddMvc();
        services.AddCors(options =>
        {
            options.AddPolicy("AllowAll",
                builder =>
                {
                    builder
                    .AllowAnyOrigin()
                    .AllowAnyMethod()
                    .AllowAnyHeader();
                });
        });

        services.Configure<MvcOptions>(options =>
        {
            options.Filters.Add(new CorsAuthorizationFilterFactory("AllowAll"));
        });
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();
        app.UseMvc();
        app.UseCors("AllowAll");    
    }

根据我在stackoverflow上看到的每个帖子/教程,或者在哪里,这是允许所有来源的正确方法.我错过了什么？

当我执行chrome.downloads.download时,它会下载文件并弹出底部的下载栏并显示它,我可以禁止它吗？

例:

/* some code to suppress download bar */

chrome.downloads.download(
  { "url": request.ImageToDownload },
  function (downloadId){
    // ...
  }
);

它返回正确数量的消息,但是填充的唯一字段是Id和ThreadId.其他一切都是空的

        var service = new GmailService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = ApplicationName,
        });

        ListMessagesResponse response = service.Users.Messages.List(emailAddress).Execute();

        IList<Google.Apis.Gmail.v1.Data.Message> messages = response.Messages;

        Console.WriteLine("Messages:");
        if (messages != null && messages.Count > 0)
        {
            foreach (var message in messages)
            {
                Console.WriteLine("{0}", message.Payload.Body);
                Console.WriteLine();
            }
        }
        else
        {
            Console.WriteLine("No Messages found.");
        }
