flask接受图像，并保存到本地

当服务端接收到图像后，要保存图像到本地可以使用 Python 的 io 模块来辅助处理接收的图像数据。以下是对服务端代码的修改，使其能够接收图像并保存到本地

from flask import Flask, request
import base64
import io
from PIL import Image

app = Flask(__name__)

def process_image(image):
    # 这里是图像处理的代码，你可以根据自己的需求来进行处理
    # 示例代码仅为演示，需要根据实际需求进行替换
    processed_image = f"Processed {image}"
    return processed_image

@app.route('/process_image', methods=['POST'])
def handle_image():
    if 'image' in request.form:
        image_data = request.form['image']
        image = base64.b64decode(image_data)

        # 保存图像到本地
        with Image.open(io.BytesIO(image)) as img:
            img.save('received_image.jpg')  # 保存为 received_image.jpg 或其他文件名

        processed_image = process_image(image)
        return processed_image
    else:
        return "No image provided."

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

Python 客户端代码

import requests
import base64

def send_image_to_server(image_path):
    url = 'http://127.0.0.1:5000/process_image'  # 这里替换为你的服务器地址

    with open(image_path, "rb") as img_file:
        encoded_string = base64.b64encode(img_file.read()).decode('utf-8')

    data = {'image': encoded_string}
    response = requests.post(url, data=data)
    return response.text

if __name__ == '__main__':
    image_path = 'path/to/your/image.jpg'  # 替换为你的图像路径
    result = send_image_to_server(image_path)
    print("Server response:", result)
