如何为ASP.NET Core Angular应用设置默认端口 [英] How to set a default port for ASP.NET Core Angular app

问题描述

我使用dotnet CLI使用模板带有Angular的ASP.NET Core 创建了一个dotnet核心项目

I created a dotnet core project with the template ASP.NET Core with Angular using the dotnet CLI

dotnet new angular

现在，每当我使用dotnet run命令运行应用程序时，角度每次都使用不同的端口.

Now, whenever I run the application using dotnet run command, angular serves with a different port each time.

我尝试在angular-cli.json中设置默认服务端口

I tried setting the default serve port in angular-cli.json

"defaults": {
  ..
  "serve": {
    "port": 4200
  }
}

虽然不起作用.

我在网上找不到任何文档，所以在哪里可以设置默认端口?

I couldn't find any documentation online, so where can I set the default port?

推荐答案

好吧，结果是，更改端口并不重要，因为我可以从URL

Okay, turns out, the changing port doesn't matter as I could access the Angular app from the url http://localhost:5000

$ dotnet run

我认为此行中指定的端口是我用来访问Angular应用程序的端口

I thought the port specified in this line is the one I should use to access the Angular app

Starting @angular/cli on port 56082...

事实证明，这不是我应该使用的那个

turns out, it's not the one I should be using

来自 MSDN :

该应用程序在以下位置启动Angular CLI服务器的实例 背景.记录类似于以下消息:NG Live Development Server正在localhost上监听，请打开您的 http://localhost :/上的浏览器. 忽略此消息-不是 组合的ASP.NET Core和Angular CLI应用程序的URL.

The app starts up an instance of the Angular CLI server in the background. A message similar to the following is logged: NG Live Development Server is listening on localhost:, open your browser on http://localhost:/. Ignore this message—it's not the URL for the combined ASP.NET Core and Angular CLI app.

但是当我尝试访问 http://localhost:5000 时，出现了SSL错误，并且挖，我在Startup.cs中找到了这一行

But when I was trying to access http://localhost:5000, I was getting an SSL error, upon more digging, I found this line in Startup.cs

app.UseHttpsRedirection();

添加此条件后，它现在可以正常工作，并且我可以通过 http://localhost:5000 <来访问Angular应用程序

After adding this condition, it's working fine now and I'm able to access the Angular app at http://localhost:5000

if (!env.IsDevelopment())
    app.UseHttpsRedirection();
