本文介绍了一个使用Python实现的客户端和服务端程序，该程序能够批量上传文件并进行处理。客户端利用requests库向指定URL发送POST请求，每次上传四个文件；服务端采用Flask框架接收这些文件，读取文件内容并将图片数据转换为RGB格式。

client端：

import requests
import os

path = '/home/users/project/data/"
url = 'http://192.168.xx.xx:8000/api_interface'

for file in os.listdir(path):
    resp = requests.post(url, files={"file1": open(os.path.join(path, file), 'rb'),
            "file2": open(os.path.join(path, file), 'rb'), "file3": open(os.path.join(path, file), 'rb'), "file3": open(os.path.join(path, file), 'rb')}

print(resp.json())

server端：

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

app = Flask(__name__)

batch_size = 16

@app.route('/api_interface', methods=['POST'])
def api_interface():
    if request.method == 'POST':
        try:
            files = [request.files[item] for item in request.files]
            if len(files) > batch_size:
                return jsonify({'error': batchsize should less than 16})

            img_bytes = [file.read() for file in files]
            images = [Image.open(io.BytesIO(image_byte)).convert('RGB') for image_byte in img_bytes]
            # 处理代码
            # .......
            output = ...
            return jsonify(output)
