flask上传文件到指定路径

项目结构如下：

首先是：视图函数uload_file.py，代码如下：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from flask import Flask,render_template,request,redirect,url_for
from werkzeug.utils import secure_filename
import os

app = Flask(__name__)

@app.route('/upload', methods=['POST', 'GET'])
def upload():
    if request.method == 'POST':
        f = request.files['file']
        basepath = os.path.dirname(__file__)  # 当前文件所在路径
        print(basepath)
        upload_path = os.path.join(basepath, 'upload_file_dir',secure_filename(f.filename))
        # 注意：没有的文件夹一定要先创建，不然会提示没有该路径
        print(upload_path)
        upload_path = os.path.abspath(upload_path) # 将路径转换为绝对路径
        print(upload_path)
        f.save(upload_path)
        return redirect(url_for('upload'))
    return render_template('upload.html')


if __name__ == '__main__':
    app.run(debug=True)

然后是html模板：upload.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>文件上传示例</h1>
    <form action="" enctype='multipart/form-data' method='POST'>
        <input type="file" name="file">
        <input type="submit" value="上传">
    </form>
</body>
</html>

最后可以发现已经成功上传
