编码发送

python 复制代码

#!/usr/bin/env python

import requests, json
import base64

ip = "127.0.0.1"


headers = {'content-type': 'application/json'}

header_dict = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko',
               "Content-Type": "application/json"}
url = 'http://{}:4488/'.format(ip)

if __name__ == "__main__":
    with open('resources/00.png', 'rb') as image_file:
        encoded_image = base64.b64encode(image_file.read()).decode('utf-8')
    post_data = {"is_url": 0,
                 "data": encoded_image}
    post_data = json.dumps(post_data).encode("utf-8")
    resp = requests.post(url=url, headers=header_dict, data=post_data)
    print(resp.json())
    # print(resp.text) 如果返回的是text
    print(resp.status_code)

解码读取

        self.logger.info(_info)
        return {"message": _info, "label": None}, 403
else:
    img_data = base64.b64decode(req_data["data"])
    bs = np.asarray(bytearray(img_data), dtype='uint8')
    img = cv2.imdecode(bs, cv2.IMREAD_COLOR)
    cv2.imwrite(image_save_path, img)
