在黑暗中走来走去......
我正在创建一个个人网页用户界面，以识别我的照片存储库中的重复项。我正在使用它作为学习Flask等的工具。我在静态文件夹中使用符号链接指向我的照片目录，该目录非常有用。工作流程是：
在发送要在浏览器中呈现的URL列表之前，所有操作都会有效。在浏览器的Developer Tools控制台中，我可以看到html是正确生成的。我保存了html并在浏览器中打开它...它按预期显示图像。
问题：服务器不会在浏览器中将html显示给用户。
我认为我的问题与我如何处理GET / POST有关，但我只是看不到它。这几乎就像浏览器没有请求（GETting html显示）。这是我第一次发帖提问，虽然我是一名长期研究员/潜伏者。感谢您的帮助，我的代码如下：
duper.py
@app.route("/")
def get_dirs():
return render_template(
'get_paths.html',
page_title='Select Directories',
jsonTreeData=dw.dirTree)
@app.route("/get_paths", methods=['GET', 'POST'])
def get_paths():
if request.method == 'POST':
dir_indexes = request.get_json()
dir_list = dw.getSearchDirs(dir_indexes)
df.searchDirs(dir_list)
urls = df.getURLResults()
if len(urls) == 0: # no dups found
print "Good job - no dups!"
else: # results ready to be displayed
return render_template(
'duply.html',
page_title='Results',
results=urls)
duply.html
{% extends "base2.html" %}
{% block content %}
<div class="container-fluid">
<table id="myTable" class="table table-bordered">
<tbody>
<tr>
<td colspan="10">
{%- for result in results %}
<tr>
{% for img_url in result %}
<td>
<a href="C:/DeDuper{{ img_url }}">
<img src="C:/DeDuper{{ img_url }}" class="img-circle" width="150" height="150">
</a>
</td>
{% endfor %}
</tr>
<tr>
<td colspan="10">
{% for img_url in result %}
<div>{{ img_url }}</div>
{% endfor %}
</td>
</tr>
{% endfor %}
</td>
</tr>
</tbody>
</table>
</div>
{% endblock %}
