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我的数组值？我尝试着:

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

但我得到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

有任何想法吗？
