今天要作一個簡單的頁面，能夠實現將文件上傳到服務器（保存在指定文件夾）html

#Sample.pyflask

 1 # coding:utf-8
 2 
 3 from flask import Flask,render_template,request,redirect,url_for
 4 from werkzeug.utils import secure_filename
 5 import os
 6 
 7 app = Flask(__name__)
 8 
 9 @app.route('/upload', methods=['POST', 'GET'])
10 def upload():
11     if request.method == 'POST':
12         f = request.files['file']
13         basepath = os.path.dirname(__file__)  # 當前文件所在路徑
14         upload_path = os.path.join(basepath, 'static\uploads',secure_filename(f.filename))  #注意：沒有的文件夾必定要先建立，否則會提示沒有該路徑
15         f.save(upload_path)
16         return redirect(url_for('upload'))
17     return render_template('upload.html')
18 
19 if __name__ == '__main__':
20     app.run(debug=True)

#upload.html服務器

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <title>Title</title>
 6 </head>
 7 <body>
 8     <h1>文件上傳示例</h1>
 9     <form action="" enctype='multipart/form-data' method='POST'>
10         <input type="file" name="file">
11         <input type="submit" value="上傳">
12     </form>
13 </body>
14 </html>
