百度AI中图像搜索的调用

（1）首先需要通过API Key和Secret Key获取access_token

入库：

import requests

import base64

'''相似图检索—入库'''

request_url = "https://aip.baidubce.com/rest/2.0/image-classify/v1/realtime_search/similar/add"

# 二进制方式打开图片文件

f = open('3.jpg', 'rb')

img = base64.b64encode(f.read())params = {"brief":"{\"name\":\"小度\", \"id\":\"1\"}","image":img,"tags":"1,1"}

access_token = '24.e3a2fa24cb2dcb2598cc395e04c2c8cc.2592000.1597571065.282335-21440784'

request_url = request_url + "?access_token=" + access_token

headers = {'content-type': 'application/x-www-form-urlencoded'}

response = requests.post(request_url, data=params, headers=headers)

if response:

     print (response.json())

输出：

{'log_id': 7788790082692754225, 'cont_sign': '3333365105,2628747969'}

检索：

request_url = "https://aip.baidubce.com/rest/2.0/image-classify/v1/realtime_search/similar/search"

# 二进制方式打开图片文件

f = open('1.jpg', 'rb')

img = base64.b64encode(f.read())

params = {"image":img,"top_num":5}

access_token = '24.e3a2fa24cb2dcb2598cc395e04c2c8cc.2592000.1597571065.282335-21440784'

request_url = request_url + "?access_token=" + access_token

headers = {'content-type': 'application/x-www-form-urlencoded'}

response = requests.post(request_url, data=params, headers=headers)

if response:

    print (response.json())

输出：
