如何在 linx docker 容器上部署 aspnet 核心应用程序而不会出现 404 错误

如何解决如何在 linx docker 容器上部署 aspnet 核心应用程序而不会出现 404 错误

我有一个 ASPNET Core 5.0 web api 应用程序在 Windows 本地成功运行，但在部署到托管在 linux 服务器上的 linux docker 容器时失败。导航到 http://internal.apps.talquinelectric.com/is/api 时不会加载页面。我收到了 404 错误。

launchSettings.json

  "$schema": "http://json.schemastore.org/launchsettings.json","iisSettings": {
    "windowsAuthentication": false,"anonymousAuthentication": true,"iisExpress": {
      "applicationUrl": "http://localhost:80","sslPort": 80
    }
  },"profiles": {

      "commandName": "IISExpress","launchbrowser": true,"launchUrl": "swagger","environmentvariables": {

  }

Startup.cs

// 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.UseSwagger();
                app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json","FixBatchAPI v1"));
            }

            //app.UseHttpsRedirection();
                        
            app.UseRouting();

            app.UseAuthorization();

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

解决方法

添加如下代码，即可打开swaggerui页面。

if (env.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json","FixBatchAPI v1"));
} 
// default,no below code
else {
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json","FixBatchAPI v1"));
}
