blocks|key|502710|text|问题是您没有到/的路由。将您的定义更改为：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|502711|ShopMyShopBundle_homepage:
++++pattern:++/
++++defaults:+{+_controller:+ShopMyShopBundle:Main:index+}

The problem is that you don't have a route for <code>/</code>. Change your definition to this:

<pre><code>ShopMyShopBundle_homepage:
 pattern: /
 defaults: { _controller: ShopMyShopBundle:Main:index }
 requirements:
 _method: GET
</code></pre>

blocks|key|718702|text|前缀是url路由的前缀。如果它等于'/‘，则意味着它将没有前缀。然后，您定义了一个模式为"it+you+with+/hello“的路由。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|718703|要为'/‘创建路由，您需要在src/Shop/MyShopBundle/Resources/config/routing.yml中添加以下行：|718704|ShopMyShopBundle_homepage:
++++pattern:++/
++++defaults:+{+_controller:+ShopMyShopBundle:Main:index+}|code-block|syntax|javascript|718705|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Prefix is the prefix for url routing. If it's equals to '/' it means it will have no prefix. Then you defined a route with pattern "it should start with /hello".

To create a route for '/' you need to add these lines in your src/Shop/MyShopBundle/Resources/config/routing.yml :

<pre><code>ShopMyShopBundle_homepage:
 pattern: /
 defaults: { _controller: ShopMyShopBundle:Main:index }
</code></pre>

blocks|key|502810|text|上面的答案是错误的，分别没有回答为什么你在查看演示内容prod-mode时遇到了问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|502811|下面是正确的答案:清除你的"prod"-cache：|502812|php+app/console+cache:clear+--env+prod|code-block|syntax|javascript|502813|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

The above answers are wrong, respectively aren't answering why you're having troubles viewing the demo-content prod-mode. 

Here's the correct answer: clear your "prod"-cache:

<pre><code>php app/console cache:clear --env prod
</code></pre>

blocks|key|502825|text|这对我来说很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|502826|cache:clear+--env=prod|code-block|syntax|javascript|502827|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This work for me:

<pre><code>cache:clear --env=prod
</code></pre>

blocks|key|718931|text|我也尝试过这个错误，我只需添加/hello/any+name就可以了，因为路径中必须有hello/name|type|unstyled|depth|inlineStyleRanges|entityRanges|data|718932|示例:不是简单地将http://localhost/app_dev.php|offset|length|718933|这样说吧，http://localhost/name_of_your_project/web/app_dev.php/hello/ai|718934|它将显示Hello+Ai。我希望我能回答你的问题。|718935|entityMap|0|LINK|mutability|MUTABLE|url|http://localhost/app_dev.php|1|http://localhost/name_of_your_project/web/app_dev.php/hello/ai^0|0|9|S|0|0|5|1Q|1|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@]|9|@$D|V|E|W|1|X]]|A|$]]|$1|F|3|G|5|6|7|Y|8|@]|9|@$D|Z|E|10|1|11]]|A|$]]|$1|H|3|I|5|6|7|12|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|13|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q]]|R|$5|M|N|O|A|$P|S]]]]

I have also tried that error , I got it right by just adding /hello/any name because it is path that there must be an hello/name

example : instead of just putting <a href="http://localhost/app_dev.php" rel="nofollow">http://localhost/app_dev.php</a>

put it like this way <a href="http://localhost/name_of_your_project/web/app_dev.php/hello/ai" rel="nofollow">http://localhost/name_of_your_project/web/app_dev.php/hello/ai</a>

it will display Hello Ai . I hope I answer your question.

blocks|key|718963|text|将symfony+2.3与php+5.5配合使用，并将内置服务器与|type|unstyled|depth|inlineStyleRanges|entityRanges|data|718964|app/console+server:run|code-block|syntax|javascript|718965|它应该输出类似如下的内容：|718966|Server+running+on+http://127.0.0.1:8000

Using symfony 2.3 with php 5.5 and using the built in server with 

<pre><code>app/console server:run
</code></pre>

which should output something like:

<pre><code>Server running on http://127.0.0.1:8000
Quit the server with CONTROL-C.
</code></pre>

then go to <a href="http://127.0.0.1:8000/app_dev.php/app/example" rel="nofollow">http://127.0.0.1:8000/app_dev.php/app/example</a>

this should give you the default, which you can also find the default route by viewing src/AppBundle/Controller/DefaultController.php

Symfony2 returns No route found for "GET /" when I try to run <a href="http://localhost/app_dev.php">http://localhost/app_dev.php</a>, but this url works: <a href="http://localhost/app_dev.php/hello/Symfony">http://localhost/app_dev.php/hello/Symfony</a>. I removed AcmeDemoBundle and I'm trying to run an example bundle from a symfony2 tutorial. What is wrong ?

symfony 2 No route found for "GET /"

当我尝试运行时，Symfony2返回No route found for "GET /“，但这个url有效：。我删除了AcmeDemoBundle，并尝试运行symfony2教程中的示例捆绑包。出什么问题了？app/config/routing.yml：ShopMyShopBundle:resource: "@Shop...
