無法將 .htaccess 整合到 nginx conf

Question

我們有 .htaccess 文件，包括：

RewriteEngine On
    # If an existing asset or directory is requested go to it as it is
    RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
    RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
    RewriteRule ^ - [L]
    # If the requested resource doesn't exist, use index.html   
RewriteRule ^ /index.html

使用某些網站或工具將其轉換為 nginx 規則後，它仍然無法正常運作。誰能幫我？
