详解Python调用华为API实现图像标签

######准备工作：在cmd中进入你所使用的python所在环境，通过pip的方式安装华为云的Python SDK
pip install huaweicloudsdkimage
pip install huaweicloudsdkcore
pip install base64
#########实验代码：运行前面步骤生成的代码
# coding: utf-8
####  导入指定的数据包  
from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkimage.v2.region.image_region import ImageRegion
from huaweicloudsdkcore.exceptions import exceptions
from huaweicloudsdkimage.v2 import *
import base64

#### base64编码格式
def image_to_base64(self):
    with open(self, 'rb') as f:
        base64_data = base64.b64encode(f.read())      #  将图像转换为 base64数据格式
        return base64_data


if __name__ == "__main__":

    ak = "yourself_ak_from_cv"  #### 输入获得的access key
    sk = "yourself_sk_from_cv"     ###输入获得的secret key
    credentials = BasicCredentials(ak, sk) \

    client = ImageClient.new_builder() \
        .with_credentials(credentials) \
        .with_region(ImageRegion.value_of("cn-north-4")) \
        .build()
####  channel =  cn-north-4   自己项目所在的大区
    try:
        request = RunImageTaggingRequest()
        request.body = ImageTaggingReq(
            limit=5,    ##  限制输出多少种类
            threshold=60,   ### 设置  confidence置信度  低于60的种类不输出
            language="zh",    ##  设置成中文显示
            image= image_to_base64('D:/data/train/动物/5.png')  ##  调用之前定义的 base64 编码 并且输入自己的图片路径
        )
        response = client.run_image_tagging(request)
        print(response)
    except exceptions.ClientRequestException as e:
        print(e.status_code)
        print(e.request_id)
        print(e.error_code)
        print(e.error_msg)
