symfony2.3中'url'和'path'有什么区别

问题描述

文件说

{# src/Acme/ArticleBundle/Resources/views/Article/recentList.html.twig #}
{% for article in articles %}
    <a href="{{ path('article_show', {'slug': article.slug}) }}">
        {{ article.title }}
    </a>
{% endfor %}

也可以像这样使用url":

also, can use 'url' like this:

<a href="{{ url('_welcome') }}">Home</a>

它让我感到困惑，使用url"和path"有什么区别?

it confused me what is the difference between using 'url' and 'path'?

推荐答案

它们非常相似.

生成相对/绝对路径:

path('contact') 将生成 /contact

生成scheme-relative/absolute url，即域+路径

Generates a scheme-relative/absolute url, ie domain + path

url('contact') 将生成 http://example.org/contact

url() 样式在使用跨域 ajax 或生成电子邮件时很有用，因为主机名不会相同.

The url() style is useful when using cross-domain ajax or generating emails, because the hostname won't be the same.
