二.代码模板

import cv2
import base64
import requests
import numpy as np
import traceback
from retrying import retry

token_list=[
  {
    "ak":"xxxxxx",
    "sk":"xxxxxxxxxx"
  },
]

def get_token(ak,sk):
  url = "https://aip.baidubce.com/oauth/2.0/token"
  params = {
    "grant_type": "client_credentials",
    "client_id": ak, # ak
    "client_secret": sk # sk
  }
  eaders={
    "content-type":"application/json; charset=utf-8",
  }
  response = requests.get(url,params=params,headers=headers,timeout=8)
  res = response.json()
  access_token = res["access_token"]
  return access_token



def baidu_api(image,token):
  """
  百度通用文字识别
  :return:
  """
  # 通用文本识别接口
  url = "https://aip.baidubce.com/rest/2.0/ocr/v1/general_basic"
  # 网络图片识别接口
  # url = "https://aip.baidubce.com/rest/2.0/ocr/v1/webimage"
  params = {
    "access_token": token,
  }
  data = {
    "image": base64.b64encode(image) #图标的bs64编码
  }
  response = requests.post(url, params=params, data=data)
  data_res = response.json()
  print(data_res)
  words = [i["words"] for i in data_res["words_result"]]
  return words

def baidu_image_recognition(img_content):
  img2=img_content
  for i in range(len(token_list)):
    token = get_token(token_list[i]["ak"], token_list[i]["sk"])
    words = baidu_api(img2,token)
  	return words
