PathLocationStrategy仅在本地工作 [英] PathLocationStrategy works only locally

问题描述

在构建哈希表时，在工作项目上，在测试项目上，哈希都存在问题.我已经在Google中阅读了以下问题: URL中没有哈希的Angular2 https://forum.ionicframework.com/t/url-routing-without -hash/81140 但我没有找到答案. 当我添加

{provide: LocationStrategy, useClass: HashLocationStrategy}

所有功能均正常运行，但带有哈希值.当我添加

{provide: LocationStrategy, useClass: PathLocationStrategy}

它仅适用于本地版本.但是工作版本不起作用 http://joxi.ru/n2YLOaMijK7Pam 如何删除此哈希 http://joxi.ru/RmzBzxDTWbjeQm 在我的构建项目中将如何工作?/p>

解决方案

PathLocationStrategy使用HTML5 pushState，该HTML5 pushState取决于<base> HTML标记.您需要告诉浏览器，所请求路径的前缀是什么.请记住将其添加到您的应用中:

<base href="/" />

在这里您可以阅读有关在Angular中路由

的更多信息.

另一件事是将每个Angular路由(在服务器端)路由到index.html中指定的基本路径.例如，这是在nodeJS中完成的方式:

app.get('/*', (req, res) => {
    res.render('index', {req, res});
});

或Apache:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.html$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.html [L]
</IfModule>

否则，当您的客户到达例如www.example.com/path/someThing时，您的服务器将在/var/www/example.com/path/someThing/中而不是/var/www/example.com/

中查找index.html文件.

I have problem with hash, on my working project when I build it, on test project all work correctly. I already read this questions in google: Angular2 without hash in the url https://forum.ionicframework.com/t/url-routing-without-hash/81140 but I didn't find answer. When I add

{provide: LocationStrategy, useClass: HashLocationStrategy}

All work correctly, but with hash. When I add

{provide: LocationStrategy, useClass: PathLocationStrategy}

It work only on local version. But working version don't work http://joxi.ru/n2YLOaMijK7Pam How can I remove this hash http://joxi.ru/RmzBzxDTWbjeQm what would it work on my build project ?

解决方案

PathLocationStrategy uses HTML5 pushState which depends on the <base> HTML tag. You need to tell the browser what will be prefixed to the requested path. Remember to add it in your app:

<base href="/" />

Here You can read more about routing in Angular

One more important thing is to route (on the server side) every Angular route to base path specified in index.html. For example, this is how it is done in nodeJS:

app.get('/*', (req, res) => {
    res.render('index', {req, res});
});

or Apache:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.html$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.html [L]
</IfModule>

Otherwise, when your customer will reach for example www.example.com/path/someThing your server will be looking for index.html file in the /var/www/example.com/path/someThing/ instead of /var/www/example.com/
