import streamlit as st import os # 標題 st.title("文件內容查看器") # 文件上傳 uploaded_file = st.file_uploader("請上傳文字或 Markdown 文件", type=["txt", "md"]) # 如果有文件被上傳 if uploaded_file is not None: # 讀取文件內容 content = uploaded_file.read().decode("utf-8") # 儲存文件內容到暫存檔 temp_file = f"temp_{uploaded_file.name}" with open(temp_file, "w", encoding="utf-8") as f: f.write(content) # 顯示文件內容 st.subheader(f"文件內容 ({uploaded_file.name})") st.write(content) # 後續操作 st.write("你可以在這裡對文件內容進行後續操作…") # 範例: 讀取暫存檔內容 with open(temp_file, "r", encoding="utf-8") as f: temp_content = f.read() st.write(f"暫存檔內容: {temp_content}") # 刪除暫存檔 os.remove(temp_file)
