在Apache Tomcat 404深层链接问题上部署角度应用程序

Question

我试图弄清楚如何设置Apache Tomcat服务器以提供具有深层链接的角度应用程序.例如:

当收到mysite.com/的请求时,静态服务器会定期返回index.html.但它拒绝mysite.com/heroes/42并返回404 - Not Found错误,除非它被配置为返回index.html.

我想在localhost/angular上提供角度应用程序,我试过以下:

1)构建角度应用:

ng build --prod --base-href .

2)将build文件夹的内容(默认值:dist)复制到$ ApacheLocation/webapps/angular

3)在$ ApacheLocation/conf/Catalina/localhost/rewrite.config中添加RewriteRules

# If an existing asset or directory is requested go to it as it is
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]  
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d  
RewriteRule ^ - [L]

# If the requested resource doesn't exist, use index.html
RewriteRule ^\/angular\/.*$ /angular/index.html

4)在主机标签下方添加阀门

 <Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true"> 
   <Valve className="org.apache.catalina.valves.rewrite.RewriteValve"/>

5)启动Tomcat服务器并转到localhost/angular会给我:

未捕获的SyntaxError:意外的令牌<用于所有.js包(例如main.bundle.js)

如果我不包含重写规则,tomcat将按预期提供localhost/angular,但会在深层链接上提供404.

我的设置配置:

• tomcat版本9.0.0.M26
• 角度版本4.4.2
• @ angular/cli:1.4.2
• 节点:8.5.0
• npm:5.4.2
• os:linux x64

Answer 1

我设法解决了这个问题,例如http:// localhost:8080/angular/player/detail/4,步骤如下:

1)使用以下命令构建角度应用:ng build --prod -bh ./ -d/angular

2)将构建的应用程序的内容复制到$ ApacheLocation/webapps/angular

3)重写规则:

RewriteCond %{REQUEST_PATH} !-f
RewriteRule ^/angular/(.*) /angular?path=$1

4)app.component.ts上的设置导航:

constructor(private activatedRoute: ActivatedRoute, private router: Router) { }

ngOnInit() {
const path = this.activatedRoute.snapshot.queryParams['path'];
const navigateTo = '/' + path;

if (path) {
  this.router.navigate([navigateTo]);
}

}

您可以在这里找到测试项目:https://github.com/avuletica/test

重写规则的说明:

# %{REQUEST_PATH} corresponds to the full path that is used for mapping.
# ! NOT character 
# '-f' (is regular file) Treats the TestString as a pathname and tests whether or not it exists, and is a regular file.
# ^ matches the beginning of the string or line
# . matches any charceter except line breaks
# * match 0 or more of the preceding token

所以基本上如果没有文件/ angular/what tomcat将完整路径作为查询字符串发送到角度应用程序并从该查询param angular处理路由.
