如何在twig模板中设置数组值

Question

如何在twig模板中通过字符串索引更改数组值？我在尝试：

{% do params['redirect_uri'] = 'http://site.loc/' %}

但是我得到了nex错误：

Unexpected token "operator" of value "=" ("end of statement block" expected) in
BWUserBundle:User/social:sign-in-thumbs.html.twig at line 4

我也在尝试：

{% set params['redirect_uri'] = 'http://site.loc/' %}

但也有错误：

Unexpected token "punctuation" of value "[" ("end of statement block" expected) in 
BWUserBundle:User/social:sign-in-thumbs.html.twig at line 4

有什么想法吗？

怎么样，

{% set params = params|merge({'redirect_uri': 'http://site.loc/'}) %}
