当应用程序在外部服务器上运行时，未找到所有请求 (404) [英] All requests are not found (404) when the application runs on an external server
问题描述
我的应用程序在使用 ng serve 命令或 ng serve --prod 命令时工作正常，但是当我使用 构建它用于生产时ng build --prod 命令，然后使用 http-server -p 8080 -c-1 dist/ng-zero 命令或 live-server -- 提供它entry-file=dist/index.html 命令，任何请求都有 404 响应.
My application works fine when served with the ng serve command or with the ng serve --prod command, but when I build it for production with the ng build --prod command and then serve it with the http-server -p 8080 -c-1 dist/ng-zero command or with the live-server --entry-file=dist/index.html command, any request has a 404 response.
我在这里查看了不同的问题及其答案，但没有任何帮助.我尝试了 HashLocationStrategy 建议，我也尝试了 useHash: true 建议，但没有成功.
I had a look at different questions and their answers here, but nothing helped. I tried the HashLocationStrategy suggestion, I tried the useHash: true one too, to no success.
启动应用程序的Http服务器:
The Http server starting the application:
$ http-server -p 8080 -c-1 dist/ng-zero
Starting up http-server, serving dist/ng-zero
Available on:
http://127.0.0.1:8080
http://192.168.0.7:8080
http://172.19.0.1:8080
Hit CTRL-C to stop the server

它确实在 http://127.0.0.1:8080/ 上打开了一个新的浏览器标签，但它是空白的，控制台说:
It does open a new browser tab on http://127.0.0.1:8080/ but it is blank and the console says:

启动应用程序的 Lite 服务器:
The Lite server starting the application:
$ ll dist/index.html
-rw-rw-r-- 1 stephane 925 oct. 12 19:35 dist/index.html
[stephane@stephane-ThinkPad-X201 ng-zero (master)]
$ live-server --entry-file=dist/index.html
Serving "/home/stephane/dev/js/projects/angular/ng-zero" at http://127.0.0.1:8080
它确实在 http://127.0.0.1:8080/ 上打开了一个新的浏览器标签，但它是空白的，控制台什么也没说.
It does open a new browser tab on http://127.0.0.1:8080/ but it is blank and the console says nothing at all.
index.html 文件:
$ cat src/index.html

我在使用 Angular 7 ^7.0.0-rc.0
I'm on Angular 7 ^7.0.0-rc.0
推荐答案
ng build --prod 命令将所有需要的文件推送到 /dist 文件夹下.您只需要在服务器中复制这些文件.
The ng build --prod command pushes all required files under the /dist folder. You just need to copy those files in the server.
如果您想提供 /dist 文件夹中的内容
If you want to serve the content from the /dist folder
- 安装
angular-http-server - 为应用程序提供
angular-http-server --path dist/
