一、进入百度AI开放平台创建动物识别应用

二、用代码获取access_token

三、实现动物识别的功能实现

四、动物识图UI_demo

---

一、进入百度AI开放平台创建动物识别应用

连接：动物识别_拍照识别动物-百度AI开放平台

登陆后操作步骤如图：

 创建完成后如图所示：

此处的API Key和Secret Key是之后需要用上的内容 

二、用代码获取access_token

调用API首先要获取access_token，它通过API Key和Secret Key获得

实现代码如下：

import requests

# client_id 为官网获取的AK， client_secret 为官网获取的SK
host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【此处填API Key】&client_secret=【此处填Secret Key】'
response = requests.get(host)
if response:
    print(response.json())

运行后可在结果中找到access_token的值

记录下access_token的值

三、实现动物识别的功能实现

代码如下：

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

# 二进制方式打开图片文件
f = open('test7.png', 'rb')        #这里是你的图片路径
img = base64.b64encode(f.read())
f.close()
params = {"image":img,"top_num": 3} #返回前3个概率比较大的
access_token = '这里放access_token的值'
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())

运行结果：

由此便实现了百度AI动物识图API的调用了 

四、动物识图UI_demo

下面是完整的代码实现
