在API测试控制台和Python 2.7中使用Microsoft Mootion API进行视频时,Iinvalid订阅密钥

我只对图片使用情感API订阅密钥,但从不对视频使用。无论我是使用API测试控制台还是尝试通过Pathon 2.7调用情感API,都没有什么区别。在这两种情况下,我都得到了一个响应状态202接受,然而,当打开操作位置时,它说

{ "error": { "code": "Unauthorized", "message": "Access denied due to 
invalid subscription key. Make sure you are subscribed to an API you are 
trying to call and provide the right key." } }

在情感API解释页面上,它说回应202意味着

服务已接受请求,稍后将启动该过程。 在响应中,有一个“操作位置”标题。客户端应进一步从该标头中指定的URL查询操作状态。

然后是 Response 401 ,这正是我的操作位置包含的内容。我不明白为什么我会得到一个回复202,看起来像是回复401。

我尝试用Python调用API,至少使用了我在互联网上找到的三个代码版本 Microsoft Emotion API for Python - upload video from memory python从内存上传视频

   import httplib
   import urllib
   import base64
   import json
   import pandas as pd
   import numpy as np
   import requests

   _url = 'https://api.projectoxford.ai/emotion/v1.0/recognizeInVideo'
   _key = '**********************'
   _maxNumRetries = 10

   paramsPost = urllib.urlencode({'outputStyle' : 'perFrame', \
                           'file':'C:/path/to/file/file.mp4'})
   headersPost = dict()
   headersPost['Ocp-Apim-Subscription-Key'] = _key
   headersPost['content-type'] = 'application/octet-stream'
   jsonGet = {}
   headersGet = dict()
   headersGet['Ocp-Apim-Subscription-Key'] = _key
   paramsGet = urllib.urlencode({})

   responsePost = requests.request('post', _url + "?" + paramsPost, \
   data=open('C:/path/to/file/file.mp4','rb').read(), \
   headers = headersPost)

   print responsePost.status_code

   videoIDLocation = responsePost.headers['Operation-Location']
   print videoIDLocation

注意,更改 _url = 'https://api.projectoxford.ai/emotion/v1.0/recognizeInVideo' 到 _url = 'https://westus.api.cognitive.microsoft.com/emotion/v1.0/recognizeInVideo' 没有帮助。

然而,之后我每半小时就等一次,然后跑一次:

   getResponse = requests.request('get', videoIDLocation, json = jsonGet,\
   data = None, headers = headersGet, params = paramsGet)

   print json.loads(getResponse.text)['status']

结果已经“运行”了几个小时,而我的视频只有大约半个小时长。

下面是我的测试控制台的外观 Testing Console for Emotion API, Emotion Recognition in Video 在这里,我使用了另一个视频,约5分钟长,可在互联网上。我在另一个使用示例中找到了该视频

这使用了一个非常类似的代码,它再次为我提供了一个响应状态202 Accepted,当打开操作位置时,订阅密钥是错误的

代码如下:

import httplib
import urllib
import base64
import json
import pandas as pd
import numpy as np
import requests



# you have to sign up for an API key, which has some allowances. Check the 
API documentation for further details:
_url = 'https://api.projectoxford.ai/emotion/v1.0/recognizeinvideo'
_key = '*********************' #Here you have to paste your 
primary key
_maxNumRetries = 10

# URL direction: I hosted this on my domain
urlVideo = 'http://datacandy.co.uk/blog2.mp4'

# Computer Vision parameters
paramsPost = { 'outputStyle' : 'perFrame'}

headersPost = dict()
headersPost['Ocp-Apim-Subscription-Key'] = _key
headersPost['Content-Type'] = 'application/json'

jsonPost = { 'url': urlVideo }

responsePost = requests.request( 'post', _url, json = jsonPost, data = None, 
headers = headersPost, params = paramsPost )
if responsePost.status_code == 202: # everything went well!
  videoIDLocation = responsePost.headers['Operation-Location']
  print videoIDLocation

互联网上还有更多的例子,它们似乎都有效,但复制其中任何一个对我来说都不起作用。有人知道会出什么问题吗?
