我正在请求面对比较API。你发送2张图片的地方,如果他们是同一个人则返回这里是链接: Face++ API
在文档中,他们提到您可以这样请求:
curl -X POST "https://api-us.faceplusplus.com/facepp/v3/compare" \
-F "api_key=<api_key>" \
-F "api_secret=<api_secret>" \
-F "face_token1=c2fc0ad7c8da3af5a34b9c70ff764da0" \
-F "face_token2=ad248a809408b6320485ab4de13fe6a9"
这是我的代码:
result = json.loads(os.popen('curl -X POST "https://api-us.faceplusplus.com/facepp/v3/compare/api_key=myKey/api_secret=mySecret/https://us-mc-prod-asset.oss-us-west-1.aliyuncs.com/mc-official/scripts/demoScript/images/demo-pic33.jpg/https://us-mc-prod-asset.oss-us-west-1.aliyuncs.com/mc-official/scripts/demoScript/images/demo-pic39.jpg"').read())
但是当我运行它时,我得到了这个:
% Total % Received % Xferd Average Speed Time Time Time Current

Traceback (most recent call last):

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
我试图以另一种方式使用请求:
result = requests.get( "https://api-us.faceplusplus.com/facepp/v3/compare/api_key=myKey/api_secret=mySecret/https://us-mc-prod-asset.oss-us-west-1.aliyuncs.com/mc-official/scripts/demoScript/images/demo-pic33.jpg/https://us-mc-prod-asset.oss-us-west-1.aliyuncs.com/mc-official/scripts/demoScript/images/demo-pic39.jpg")
但是,我得到了这个:
<Response [404]>
答案 0 :(得分:0)
curl命令格式错误,因此您收到错误Could not resolve host: api_key=myKey
而不是有效的JSON返回数据。
但是,(不要脱离你的问题),我是否可以建议您使用requests
(如果必须使用标准python库,则为urllib2
)来发送HTTP请求。以你自己的方式调用curl会产生意想不到的结果,例如你现在正在处理的事情。
此外,requests
实际上对响应对象有一个非常方便的json()
方法。这将使您的代码更清晰,更容易进行故障排除。以下是文档中的示例:
