关联接口，依赖接口的用法

##############关联接口的用法
思想：在实际工作中，往往需要测试到关联接口(依赖接口)，比如购买，我们需要保证用户是登录状态，所以在接口测试中需要拿到登录的token值，

import requests

# 1. 请求第一个接口 从响应中提取得到access_token
def get_access_token():
    url = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=kPoFYw85FXsnojsy5bB9hu6x&client_secret=l7SuGBkDQHkjiTPU3m6NaNddD6SCvDMC'

    res1 = requests.get(url)
    access_token = res1.json()['access_token']
    print(access_token)
    return access_token


def baidu_ocr(access_token):
    # 2. 实用提取到的数据

    url = f'https://aip.baidubce.com/rest/2.0/ocr/v1/general_basic?access_token={access_token}'

    data = {
        'url': 'http://upload-images.jianshu.io/upload_images/7575721-40c847532432e852.png? imageMogr2/auto-orient/strip%7CimageView2/2/w/1240'
    }

    res2 = requests.post(url, data=data)

    print(res2.json())


def main():
    token = get_access_token()
    baidu_ocr(token)

if __name__ == '__main__':
    main()
