streamlit的components.html如何引入一个html文件？

Question

streamlit的components.html能够使用一个字符串，展示内容，例如：

import streamlit as st
import streamlit.components.v1 as components

# bootstrap 4 collapse example
components.html(
    """

            <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
            Collapsible Group Item #1
            </button>
          </h5>
        </div>
        <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
          <div class="card-body">
            Collapsible Group Item #1 content
          </div>
        </div>
      </div>
      <div class="card">
        <div class="card-header" id="headingTwo">

          </h5>
        </div>
        <div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordion">
          <div class="card-body">
            Collapsible Group Item #2 content
          </div>
        </div>
      </div>
    </div>
    """,
    height=600,
)

现在我有一个test.html文件，不想写一个那么长的字符串，而是想直接引入到components.html(XXXXXX)中的XXXXXX位置。应该怎么办呢？谢谢

Answer 1

text=""
with open("test.html") as fp: #如果遇到decode错误，就加上合适的encoding
    text=fp.read()
components.html(text)

pyecharts的图表对象可以用render_embed得到HTML内容，不用本地文件转存。
