32新建Python文件ocrcode.py(文件名随意)文件,代码为:
# -*- coding:utf-8 -*-
# author:f0ngf0ng
import argparse
# 导入 ddddocr
import ddddocr
from aiohttp import web
parser = argparse.ArgumentParser()
# 使用未暂用的端口
parser.add_argument("-p", help="http port",default="9998")
args = parser.parse_args()
ocr = ddddocr.DdddOcr()
port = args.p
async def handle_cb(request):
return web.Response(text=ocr.classification(img_base64=await request.text()))
app = web.Application()
app.add_routes([
web.post('/reg', handle_cb),
])
if __name__ == '__main__':
web.run_app(app, port=port)
