如何用菲尼克斯LiveView处理表单文件？

defp deps do
  [
    {:phoenix_live_view, "~> 0.16"}
  ]
end

<input type="file" phx-change="handleFileChange">

def handle_event("handleFileChange", %{"file" => file}, socket) do
  # 处理文件逻辑
  {:noreply, socket}
end

def handle_event("handleFileChange", %{"file" => file}, socket) do
  file_path = "/path/to/save/#{file.filename}"
  File.write(file_path, file.content)
  {:noreply, socket}
end

def mount(_params, _session, socket) do
  {:ok, assign(socket, files: [])}
end

def handle_event("handleFileChange", %{"file" => file}, socket) do
  file_path = "/path/to/save/#{file.filename}"
  File.write(file_path, file.content)
  {:noreply, assign(socket, files: [file_path | socket.assigns.files])}
end

<ul>
  <%= for file_path <- @files do %>
    <li><%= file_path %></li>
  <% end %>
</ul>
<button phx-update="handleFileChange">Refresh</button>
