python - 在 Flask 中上传图片

Question

我必须在我的项目目录的静态文件夹中上传一些图像，但我不知道如何对我的代码说出来。在下面的 code.py 中，我可以上传图像并将其存储在静态文件夹同一级别的项目目录中，但我希望该图像可以存储在静态文件夹中。

@app.route('/uploader', methods = ['GET', 'POST'])
def upload_file():
   if request.method == 'POST':
      f = request.files['file']

      f.save(secure_filename(f.filename))
      return render_template('end.html')

我必须做什么？？谢谢大家

您需要定义上传文件夹

来自 flask 文档

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 = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])

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

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 a 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))

所以你的代码应该是 UPLOAD_FOLDER = '/path/to/static/images' 或类似的东西
