angular - 构建 Angular 应用程序并放置在服务器上

Question

我正在开发一个 angular6 应用程序，我想生成一个构建以在我的服务器上进行测试，目前我使用 ng 服务器并且它在我的浏览器上运行而不会产生任何错误。

c:\Users\emiry\Desktop\Angular\Projects\StartingNewProject

当我运行 ng build 命令时，它会为/dist 文件夹生成一个构建并且没有返回任何错误

在我的机器上我已经安装了 wamp64 所以我得到这个由 ng 生成的构建并将它放在我的 www 文件夹中

C:\wamp64\www\StartingNewProject

仅此就足以让我能够在服务器上运行我的应用程序吗？

当我尝试通过 http://localhost/startingnewproject/访问我在服务器上的应用程序时

它在浏览器控制台中返回以下错误

Failed to load resource: the server responded with a status of 404 (Not Found) polyfills.js:1 Failed to load resource: the server responded with a status of 404 (Not Found) styles.js:1 Failed to load resource: the server responded with a status of 404 (Not Found) vendor.js:1 Failed to load resource: the server responded with a status of 404 (Not Found) main.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)

我尝试访问如下

file:///C:/wamp64/www/StartingNewProject/index.html

5index.html:13 GET file:///C:/runtime.js 0 () /C:/favicon.ico:1 GET file:///C:/favicon.ico 0 () translate.google.com/gen204?nca=te_li&client=te_lib&logld=vTE_20180625_00:1 GET file://translate.google.com/gen204?nca=te_li&client=te_lib&logld=vTE_20180625_00 0 ()

file:///C:/wamp64/www/StartingNewProject/index.html

GET file:///C:/runtime.js 0 () /C:/favicon.ico:1 GET file:///C:/favicon.ico 0 ()

当我尝试访问根目录以查看文件夹和文件时，我完全可以，问题是当我加载 index.html 时

Answer 1

项目存在的问题是试图找到它的依赖项。 Angular 项目的 index.html 文件应该包含一个如下所示的标签:

<base href="/">

或类似的。这意味着，当它查找依赖项时，它会查找相对于根的关系。在你的情况下，根目录旁边没有(即本地主机)，它们在 StartingNewProject

下

您可以使用 ng build --prod --base-href=/StartingNewProject/ 生成一个新构建，这将为您添加基本 href 标签。请注意，在此处同时包含前导斜线和尾随斜线很重要。

可以在 Angular 文档中找到更多详细信息，here
