问题描述
刚刚启动了一个新的 .NET Core 2.0 应用程序，但突然出现奇怪的行为，似乎找不到任何东西.
Just started a fresh .NET Core 2.0 app, but getting weird sudden behaviour, can't seem to find anything.
点击我的BuildWebHost().的.Run()时弹出以下错误:
The following error pops up when hitting the .Run() of my BuildWebHost().:

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Private.CoreLib.dll
A path base can only be configured using IApplicationBuilder.UsePathBase().
这是我的 Program.cs
Here's my Program.cs
public class Program
{
public static void Main(string[] args)
{
BuildWebHost(args).Run();
}
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.Build();
}
这是我的 Startup.cs
Here's my Startup.cs
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; set; }
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
//Swagger
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info
{
Title = "2Commit Blogpost API",
Version = "v1"
});
});
//Mediatr
services.AddScoped<IMediator, Mediator>();
services.AddTransient<SingleInstanceFactory>(sp => sp.GetService);
services.AddTransient<MultiInstanceFactory>(sp => sp.GetServices);
services.AddMediatorHandlers(typeof(Startup).Assembly);
//MongoDB
services.Configure<MongoSettings>(s =>
{
s.Database = Configuration.GetSection("MongoConnection:Database").Value;
});
services.AddSingleton<IMongoClient, MongoClient>(client => new MongoClient(Configuration.GetSection("MongoConnection:ConnectionString").Value));
//BL
services.AddTransient<IUserService, UserService>();
//DAL
services.AddTransient<IRepository, MongoRepository>();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
//Swagger
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "BlogPost API");
});
app.UseMvc();
}
}
我似乎无法理解这个！
更新1:
该错误仅在从命令行运行我的项目时弹出，通过 IIS Express 运行时没有错误.
The error only pops up when running my project from the command line, when running it trough IIS Express, no errors.
这是我的启动设置
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:51592/swagger",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"API": {
"commandName": "Project",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:5000/swagger"
}
}
}
推荐答案
好的，在 1.X 中，您可以在从命令行运行时在 launchOptions 中添加到 applicationUrl 的基本路径，现在它仅在使用 IIS 时有效.
OK, in 1.X you could just add a base path to your applicationUrl in your launchOptions while running from command line, now it only works when using IIS.
在我的启动设置中，更改我的 CLI 配置文件
in my launchSettings, changing my CLI profile from using
"applicationUrl": "http://localhost:5000/swagger"
到
"applicationUrl": "http://localhost:5000"
成功了.
