python3处理docx并flask显示

前言：

最近有需求处理docx文件，并讲内容显示到页面，对world进行在线的阅读，这样我这里就使用flask+Document对docx文件进行处理并显示，下面直接上代码：

Document处理：

首先下载Document的库文件，先直接安装最新版的python-docx，如果不行则换成1.1.0版本：

pip install python-docx
pip install python-docx==1.1.0

处理docx代码如下：

def ReadVADocx(ProjectName,DocxName):
    docxfilepath = vaReportDir + "\\" + ProjectName + "\\" + DocxName
    paragraphs = ReadDocx(docxfilepath)
    return paragraphs

def ReadDocx(docxfilepath):
    doc = Document(docxfilepath)
    paragraphs = list()
    pattern = re.compile('rId\d+')
    for graph in doc.paragraphs:
        level = graph.style.name.split(' ')[-1]
        if level == "Normal":
            level = None
        elif level == "Preformatted":
            level = None
        paragraph = {
            'text': graph.text,
            'level': level,
            'images': ""
        }
        paragraphs.append(paragraph)
        for run in graph.runs:
            if run.text == '':
                contentID = pattern.search(run.element.xml)
                if contentID:
                    contentID = contentID.group(0)
                    try:
                        contentType = doc.part.related_parts[contentID].content_type
                    except KeyError as e:
                        print(e)
                        continue
                    if not contentType.startswith('image'):
                        continue
                    imgData = doc.part.related_parts[contentID].blob
                    image_base64 = base64.b64encode(imgData).decode('utf-8')
                    paragraph = {
                        'text':  run.text,
                        'level': run.style.name.split(' ')[-1] if run.style.name.startswith('Heading') else None,
                        'images': image_base64
                    }
                    paragraphs.append(paragraph)

上述代码会对docx文件进行遍历，并将对应的内容和等级放入数组中

下面是调用代码：

@app.route('/ViewVADocx', methods=['GET'])
def ViewVADocx():
     try:
        DocxName = request.args.get('docx')
        ProjectName = request.args.get('name')
        paragraphs = engine.ReadVADocx(ProjectName,DocxName)
        return render_template("viewdocx.html", n_getname=ProjectName, n_user=user,paragraphs=paragraphs)
     except Exception as e:
         return render_template('error-500.html')

html编写：

然后就是需要讲对应的内容在页面进行展示，下面列出html代码：

{% extends "mould.html" %}

{% block head %}
{% endblock %}

{% block body %}
        <!--body wrapper start-->
        <div class="wrapper">
            <div class="floating-box" id="floatingBox">↑回到顶部↑</div>

              <!--Start Page Title-->
               <div class="page-title-box">
                    <h4 class="page-title">{{ n_getname }}：扫描节点线</h4>
                    <div class="clearfix"></div>
                 </div>
                  <!--End Page Title-->
                <!--Start row-->
                  <div class="row">
                     <div class="col-md-12">
                         <div class="white-box">
                            <h2 style="font-weight: bold;">快速导航：</h2>
                            {% for paragraph in paragraphs %}
                                {% if paragraph.level == "1"  %}
                                    <p>
                                    <a href="#Section{{ loop.index0 }}" class="hover-link" style="font-weight: bold;">{{ paragraph.text }}</a>
                                {% elif  paragraph.level == "2" %}
                                    <p style="text-indent: 25px;">
                                    <a href="#Section{{ loop.index0 }}" class="hover-link2" style="font-weight: bold;">{{ paragraph.text }}&#9;</a>
                                    </p>
                                {% endif %}
                            {% endfor %}
                         </div>
                            {% for paragraph in paragraphs %}
                                {% if paragraph.level  %}
                                    {% if paragraph.level == "Title" %}
<!--                                        <h2 align="center">{{ paragraph.text }}</h2>-->
                                    {% elif  paragraph.level == "1" %}
                                        </div>
                                        <div class="white-box">
                                        <h{{ paragraph.level }} id="Section{{ loop.index0 }}" style="font-weight: bold;">{{ paragraph.text }}</h{{ paragraph.level }}>
                                    {% else %}
                                        <h{{ paragraph.level }} id="Section{{ loop.index0 }}">{{ paragraph.text }}</h{{ paragraph.level }}>
                                    {% endif %}
                                {% else %}
                                    {% if paragraph.images %}
                                        <p><img src="data:image/png;base64,{{ paragraph.images }}" alt="Image"></p>
                                    {% else %}
                                        <p style="color: black;">{{ paragraph.text }}</p>
                                    {% endif %}
                                {% endif %}
                            {% endfor %}

                     </div>
                </div>
        </div>

{% endblock %}

{% block list %}
        <style>
           .hover-link {
                font-size: 20px;
            }
            .hover-link:hover {
                color: red;
                font-size: 30px;
            }
            .hover-link2 {
                font-size: 15px;
            }
            .hover-link2:hover {
                color: red;
                font-size: 20px;
            }
        </style>
      <style>
        /* CSS 样式，用于定义悬浮框的外观 */
        .floating-box {
          position: fixed;
          bottom: 20px;
          right: 20px;
          width: 80px;
          height: 50px;
          background-color: #ff9900;
          color: #fff;
          text-align: center;
          line-height: 50px;
          cursor: pointer;
        }
      </style>
  <script>
    // JavaScript 代码
    var floatingBox = document.getElementById('floatingBox');

    // 点击事件监听器
    floatingBox.addEventListener('click', function() {
      window.scrollTo({ top: 0, behavior: 'smooth' });
    });
  </script>
{% endblock %}

其中添加了样式和回到顶部等小功能，方便浏览，最后的使用效果如下：

后记：

代码只做了docx文件的内容展示，包括文字和图片，并对等级进行了划分，没有对docx的修改功能，感兴趣的可以自己研究下
