网页画面
核心代码(网页)
- 点击按钮弹窗选择 txt 文件（index2.html）
<form method="post" enctype="multipart/form-data">
<p class="font-weight-bold">上传文本(只支持.txt)</p>
<input type="file" name="file"/><br><br>
<input type="submit" class="btn btn-primary font-weight-bold text-white" value="生成内容"/>
</form>
- 获取 txt 文件（app2.py）
file = request.files["file"]
- 保存文件到预设的文件目录下，直接 open read 读取，得到文本内容 a（app2.py）
if file:
print(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], file.filename))
print('C:/Users/'+username+'/Desktop/'+file.filename)
f = open('C:/Users/'+username+'/Desktop/'+file.filename, "r+", encoding='utf-8')
filecontent = f.read()
a = str(filecontent)
- 将文本内容 a 发送到index2.html网页（app2.py）
return render_template('index2.html', a=a)
- 网页获取文本内容并显示（index2.html）
