python - 在通过烧瓶中的http post请求上传之前压缩文件

问题描述

我正在制作的网络工具上传速度很慢，所以我想上传压缩文件。是否可以在 Flask 中上传文件（通过 http post 请求）之前对其进行压缩？

我想将 gzip 与以下内容一起使用，但不确定是否可以在上传之前进行压缩。


    test = open(path_to_uploaded_file, mode="rb")
                    test_2 = test.read()
                    hi = gzip.compress(test_2)
                    new_file = open(session["file_path"].replace(".mgh", ".mgz"), "wb+")
                    new_file.write(hi)

这是我用于文件上传的框架（来源：https ://flask.palletsprojects.com/en/1.1.x/patterns/fileuploads/ ）


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

    UPLOAD_FOLDER = '/path/to/the/uploads'
    ALLOWED_EXTENSIONS = {'txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'}

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

    def allowed_file(filename):
        return '.' in filename and \
               filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS

    @app.route('/', methods=['GET', 'POST'])
    def upload_file():
        if request.method == 'POST':
            # check if the post request has the file part
            if 'file' not in request.files:
                flash('No file part')
                return redirect(request.url)
            file = request.files['file']
            # if user does not select file, browser also
            # submit an empty part without filename
            if file.filename == '':
                flash('No selected file')
                return redirect(request.url)
            if file and allowed_file(file.filename):
                filename = secure_filename(file.filename)
                file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
                return redirect(url_for('uploaded_file',
                                        filename=filename))
        return '''
        <!doctype html>
        <title>Upload new File</title>
        <h1>Upload new File</h1>
        <form method=post enctype=multipart/form-data>
          <input type=file name=file>
          <input type=submit value=Upload>
        </form>
        '''

谢谢！
