Google 视觉 API - 运行使用 URL 的显式内容检测（安全搜索）

Question

我在通过 Vision API 的安全 Search/Explicit 内容检测从 URL 中获取图像时遇到问题。 Python 示例可在此处找到：

https://github.com/googleapis/python-vision/blob/HEAD/samples/snippets/detect/detect.py

如果我要将以下内容保存在 python 文件中 - 运行的最佳方式是什么？我尝试了 !python detect.py safe-search-uri http://www.photos-public-domain.com/wp-content/uploads/2011/01/old-vw-bug-and-van.jpg 但它不起作用。也许我遗漏了一些代码或运行以错误的方式使用它？

上面的示例代码github:

    from google.cloud import vision
    client = vision.ImageAnnotatorClient()
    image = vision.Image()
    image.source.image_uri = uri

    response = client.safe_search_detection(image=image)
    safe = response.safe_search_annotation

    # Names of likelihood from google.cloud.vision.enums
    likelihood_name = ('UNKNOWN', 'VERY_UNLIKELY', 'UNLIKELY', 'POSSIBLE',
                       'LIKELY', 'VERY_LIKELY')
    print('Safe search:')

    print('adult: {}'.format(likelihood_name[safe.adult]))
    print('medical: {}'.format(likelihood_name[safe.medical]))
    print('spoofed: {}'.format(likelihood_name[safe.spoof]))
    print('violence: {}'.format(likelihood_name[safe.violence]))
    print('racy: {}'.format(likelihood_name[safe.racy]))

    if response.error.message:
        raise Exception(
            '{}\nFor more info on error messages, check: '
            'https://cloud.google.com/apis/design/errors'.format(
                response.error.message))

如果您只是执行了问题中包含的代码片段，那么您没有正确地将值 uri 传递给代码。您需要解析在 python 命令中传递的参数。您可以通过添加 argparse 来做到这一点。

from google.cloud import vision
import argparse

# Parse the options in this part #
parser = argparse.ArgumentParser(description='Safe search')
parser.add_argument(
    '--safe-search-uri',
    dest='uri'
    )
args = parser.parse_args()
uri = args.uri

# [START vision_safe_search_detection_gcs]
def detect_safe_search_uri(uri):
    """Detects unsafe features in the file located in Google Cloud Storage or
    on the Web."""
    from google.cloud import vision
    client = vision.ImageAnnotatorClient()
    image = vision.Image()
    image.source.image_uri = uri

    response = client.safe_search_detection(image=image)
    safe = response.safe_search_annotation

    # Names of likelihood from google.cloud.vision.enums
    likelihood_name = ('UNKNOWN', 'VERY_UNLIKELY', 'UNLIKELY', 'POSSIBLE',
                       'LIKELY', 'VERY_LIKELY')
    print('Safe search:')

    print('adult: {}'.format(likelihood_name[safe.adult]))
    print('medical: {}'.format(likelihood_name[safe.medical]))
    print('spoofed: {}'.format(likelihood_name[safe.spoof]))
    print('violence: {}'.format(likelihood_name[safe.violence]))
    print('racy: {}'.format(likelihood_name[safe.racy]))

    if response.error.message:
        raise Exception(
            '{}\nFor more info on error messages, check: '
            'https://cloud.google.com/apis/design/errors'.format(
                response.error.message))
# [END vision_safe_search_detection_gcs]

detect_safe_search_uri(uri)

使用命令 !python detect.py --safe-search-uri http://www.photos-public-domain.com/wp-content/uploads/2011/01/old-vw-bug-and-van.jpg 进行测试：
