[Python知识库]python实现微信机器人颜值评分

先上效果图

多个人在同一个图上可以一起识别，可以获取颜值评分、岁数、性别、表情、是否佩戴眼镜等一系列信息。有想要尝试的小伙伴可以边看边尝试呦!

首先，需要去百度开放平台申请token，后续识别需要使用。
然后需要用到四个python包

from wxpy import *
import requests
import base64
import datetime
from PIL import Image, ImageDraw

wxpy 用来获取微信好友发来的信息
requests 请求获取token
base64 图片转base64
datetime 获取日期
PIL 图像处理工具

引入之后，初始化程序

self.bot = Bot()
self.myself = self.bot.self
self.friends = self.bot.friends()
self.token = ''
self.img = []

初始化微信

@grade.bot.register()
    def reply (msg):
        if msg.type == 'Picture':
            if str(msg.member) == 'None':
                state = 0
                name = str(msg.sender)[9:-1]
                member = ''
                print('收到%s发来的图片...' % name)
            else:
                name = msg.sender.name
                member = str(msg.member)[9:-1]
                state = 1
                print('收到群%s里%s发来的图片...' %(name, member))

获取百度开放平台token

def getToken (self):
    host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=client_id&client_secret=client_secret'
    res = requests.get(host)
    if res:
        self.token = res.json()['access_token']

请求打分接口

def faceLevel (self):
    print('尝试请求百度接口...')
    params = "{\"image\":\"%s\",\"image_type\":\"BASE64\",\"face_field\":\"age,beauty,expression,face_shape,gender,glasses,landmark,landmark150,race,quality,eye_status,emotion,face_type\",\"max_face_num\":\"9\"}" % self.img[0]['base64']
    url = "https://aip.baidubce.com/rest/2.0/face/v3/detect"
    request_url = url + "?access_token=" + self.token
    headers = {'content-type': 'application/json'}
    res = requests.post(request_url,data=params,headers=headers)
	// 请求成功 获取结果
    if res.status_code == 200 and res.json()['error_code'] == 0:
        faceList = res.json()['result']['face_list']
    else:
        del self.img[0]
        print('检测失败')

画出脸所在位置

def selectFace (self, img, data):
    saveUrl = img[:-4]+ '_select' +img[-4:]
    base = Image.open(img)
    d = ImageDraw.Draw(base)
    for i in range(len(data)):
        left = data[i]['location']['left']
        top = data[i]['location']['top']
        width = data[i]['location']['width']
        height = data[i]['location']['height']
        age = str(data[i]['age'])
        beauty = str(data[i]['beauty'])
        d.rectangle([left,top,left + width,top + height], outline="red")
        d.text((left + 10, top + 10), "NO.%s\nage:%s\nbeauty:%s" %(str(i + 1), age, beauty), fill='red')
        
    base.save(saveUrl)
    base.close()

完成!!!
