python3 flask:如何以HTML显示JSON结果

现在我想将JSON数据发送到HTML,我只显示字典数据(JSON),如何在HTML中显示字典的值。 python代码是:

@app.route('/upload',methods=['get','post'])
DeF上传():
if request.method='post':
img_file=request.files['img_file']
如果img_文件和允许的_文件(img_文件.filename):
文件名=安全文件名(img_file.filename)
img_file.save(os.path.join(app.config['upload_folder'],filename))。
raw_img_url='./static/asset/uploads/'+文件名
结果img_url='./static/asset/output/line/'+文件名

比率=检查横幅(文件名)
result_dict='result':比率

返回render_template(“upload.html”,result_img_url=result_img_url,result=json.dumps(result_dict))。
其他:
返回'''确定</p>''
其他:
返回重定向(url_for('upload'))
< /代码> 

HTML代码:

%extends“base.html”%
%块内容%

<form method=“post”action=“/upload”enctype=“multipart/form data”>
<input type=“file”id=“img_file”name=“img_file”class=“col-sm-4”>
<input type=“submit”value=“check”class=“btn”>
&表格/表格;

& P & GT;
%if result_img_url%
<img src=“result_img_url”width='400'height='350'>
{%Endif%}
& lt;/p & gt;

& UL & GT;

<li>结果</li>

&L/UL & GT;


%端块%}
< /代码> 

但是结果html是,但是我只想显示结果的值:

.

@app.route('/upload', methods=['GET', 'POST'])
def upload():
    if request.method == 'POST':
        img_file = request.files['img_file']
        if img_file and allowed_file(img_file.filename):
            filename = secure_filename(img_file.filename)
            img_file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            raw_img_url = './static/asset/uploads/' + filename
            result_img_url = './static/asset/output/Line/' + filename

            ratio = check_banner(filename)
            result_dict = {'result': ratio}

            return  render_template("upload.html", result_img_url=result_img_url, result=json.dumps(result_dict))
        else:
            return ''' ok</p> '''
    else:
        return redirect(url_for('upload'))


HTML代码:

{% extends "base.html" %}
{% block content %}

<form method="post" action="/upload" enctype="multipart/form-data">
  <input type="file" id="img_file" name="img_file" class="col-sm-4">
  <input type="submit" value="check" class="btn">
</form>

<p>
{% if result_img_url %}
    <img src="{{ result_img_url }}" width='400' height='350'>
{% endif %}
</p>

<ul>

<li>{{result}}</li>

</ul>


{% endblock %}


但结果html是,但我只想显示结果的值:
