华为云SDK的那些事（笑哭

今天在搞一个OCR的SDK，和华为工程师搞了一下午，妈的，问题居然出现在他的源码上。。。

from HWOcrClientAKSK import HWOcrClientAKSK

    username = "xxx"

       response=ocrClient.request_ocr_service_base64('/v1.0/ocr/general-text','./data/id-card-demo.png',option)
       print("Status code:"+str(response.status_code)+" content:"+response.text)

# AK SK demo code


    AK="hhhhhhhhhhhhhhhhh"  #AK from authentication
    SK="hhhhhhhhhhhhhhhhh"   #SK from authentication
    endpoint="ocr.cn-north-4.myhuaweicloud.com"  #http endpoint information
    ocr_client=HWOcrClientAKSK(AK,SK,endpoint)  #initialize ocr_client from ak,sk and endpoint information
    option={}
    # option["side"]="front"
    try:
       response=ocr_client.request_ocr_service_base64("/v1.0/ocr/general-text",'./data/general-text-demo.jpg',option) #call OCR interface to recognize picture
       print("Status code:"+str(response.status_code)+" content:"+response.text)
    except ValueError as e:

这里AK和SK要自己修改，其他的都搞好了，就是这个参数一致反馈错误，最后的解决办法是将
option["side"]="front"注释掉。。。什么鬼妈的
