Question

我试图获取上传文件夹路径。

UPLOAD_FOLDER = '/uploads'
ALLOWED_EXTENSIONS = set(['png', 'jpg', 'jpeg', 'gif'])

app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER

我在路径中上传图片：

.
└── uploads
    └── img_articles
        └── 2017
            └── 02
                └── image.jpg

我想在Jinja模板中使用image.jpg

{% extends "layout.html" %}
{% block content %}
<div class="container">
  <img src="{{image_path}}" alt="">
</div>
{% endblock %}

我该怎么办？

Answer 1

查看专业人士信息中的Uploading Files Pattern。

定义上传路线：

from flask import send_from_directory

@app.route('/uploads/<filename>')
def uploaded_file(filename):
    return send_from_directory(app.config['UPLOAD_FOLDER'],
                               filename)

在模板中，您可以使用路线获取文件名

<img src="{{ url_for('uploaded_file', filename='yourimage.jpg') }}">
