烧瓶请求文件上传到保管箱 - Python

简介：

本文主要介绍Python中如何通过烧瓶（Flask）框架来实现将文件上传到保管箱（Dropbox）的操作。

实现步骤：
  1. 导入所需的Python库：
from flask import Flask, request, redirect, url_for
import dropbox
import os
  1. 初始化烧瓶：
app = Flask(__name__)
  1. 创建上传文件的页面：
@app.route('/', methods=['GET', 'POST'])
def upload_file():
    if request.method == 'POST':
        file = request.files['file']
        filename = file.filename
        file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
        return redirect(url_for('uploaded_file', filename=filename))
    return '''
        <!doctype html>
        <html>
        <head>
        <title>Upload new File</title>
        </head>
        <body>
        <h1>Upload new File</h1>
        <form action="" method=post enctype=multipart/form-data>
        <p><input type=file name=file>
           <input type=submit value=Upload>
        </form>
        </body>
        </html>
    '''
  1. 定义保存上传文件的文件夹：
app.config['UPLOAD_FOLDER'] = 'uploads'
  1. 创建上传成功页面：
@app.route('/uploaded_file')
def uploaded_file():
    filename = request.args['filename']
    upload_to_dropbox(filename)
    return 'file uploaded successfully to dropbox'
  1. 定义上传到Dropbox的函数：
def upload_to_dropbox(filename):
    access_token = 'your_dropbox_access_token'
    client = dropbox.Dropbox(access_token)
    with open('uploads/' + filename, 'rb') as f:
        client.files_upload(f.read(), '/' + filename)
  1. 运行烧瓶：
if __name__ == '__main__':
    app.run(debug=True)
结束语：

通过以上步骤，我们完成了在Python中使用烧瓶框架实现将文件上传到Dropbox的操作。当然，我们也可以根据需要对程序进行自定义的修改和扩展。
