Python创建上传接口

在Python中，创建一个文件上传接口通常涉及到Web开发和文件处理。这里我们可以使用Flask或Django等流行的Web框架，结合HTML表单来实现这个功能。以下是一个简单的示例，使用Flask：

from flask import Flask, request, send_from_directory

app = Flask(__name__)

# 设置静态文件目录，上传文件将保存在这里
UPLOAD_FOLDER = 'uploads'
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER

# 允许指定类型的文件上传
ALLOWED_EXTENSIONS = {'txt', 'pdf', 'png', 'jpg', 'jpeg'}

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

@app.route('/upload', methods=['POST'])
def upload_file():
    if 'file' not in request.files:
        return 'No file part'
    
    file = request.files['file']
    if file.filename == '':
        return 'No selected file'
    if file and allowed_file(file.filename):
        filename = secure_filename(file.filename)
        file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
        return f"File {filename} uploaded successfully."
    else:
        return "Invalid file type."

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