Question

我正在使用Microsoft Emotion API在Rails应用程序中处理视频中的情绪。我能够调用API来提交操作，但现在我必须查询另一个API以获取操作的状态，一旦完成它将提供情绪数据。

我的问题是，当我查询结果API时，响应是找不到我的操作。如同，它不存在。

我首先通过我的控制器发送了以下请求，这非常有效：

#static controller
    uri = URI('https://api.projectoxford.ai/emotion/v1.0/recognizeinvideo')
    uri.query = URI.encode_www_form({})

    request = Net::HTTP::Post.new(uri.request_uri)
    request['Ocp-Apim-Subscription-Key'] = ENV['MEA_SubscriptionKey1']
    request['Content-Type'] = 'application/octet-stream'
    request.body = File.read("./public/mark_zuck.mov")

    response = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http|
        http.request(request)
    end

    # Get response headers
    response.each_header do |key, value|
      p "#{key} => #{value}"
    end

    # Get operation location and id of operation
    operation_location = response["operation-location"]
    oid = operation_location.split("/")[6]

第一个电话的回复是：

"operation-location => https://api.projectoxford.ai/emotion/v1.0/operations/e7ef2ee1-ce75-41e0-bb64-e33ce71b1668"

该协议用于获取"operation-location" url的末尾，即操作ID，并将其发送回结果API网址，如下所示：

    # parse operation ID from url and add it to results API url
    url = 'https://api.projectoxford.ai/emotion/v1.0/operations/' + oid
    uri = URI(url)
    uri.query = URI.encode_www_form({})

    request = Net::HTTP::Get.new(uri.request_uri)
    request['Ocp-Apim-Subscription-Key'] = ENV['MEA_SubscriptionKey1']
    response = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http|
        http.request(request)
    end

    # Get response headers
    response.each_header do |key, value|
      p "#{key} => #{value}"
    end

我得到的结果是：

"{\"error\":{\"code\":\"Unspecified\",\"message\":\"Operation not found.\"}}"

当我使用通过我的应用创建的操作的操作ID查询Microsoft在线API控制台时，我得到相同的结果。

有没有人对此有任何想法或经验？我将不胜感激。

你不需要解析＆＃34; oid＆＃34;超出＆＃34;运营地点＆＃34;标题，因为它已经是您应该获取状态的URL。以下代码适用于我。用它来看看你是否仍然看到了这个问题。

require 'net/http'
require 'uri'

uri = URI('https://api.projectoxford.ai/emotion/v1.0/recognizeinvideo')
uri.query = URI.encode_www_form({})

request = Net::HTTP::Post.new(uri.request_uri)
request['Ocp-Apim-Subscription-Key'] = '<your key>'
request['Content-Type'] = 'application/octet-stream'
videoFile = File.open("c:\\1mb.mp4", "rb")
request.body = videoFile.read
videoFile.close

response = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http|
    http.request(request)
end

puts response.message
puts response.read_body

# Get response headers
response.each_header do |key, value|
  p "#{key} => #{value}"
end

# Get operation location url for subsequent calls 
operation_location = response["operation-location"]

operation_url = operation_location
uri = URI(operation_url)
uri.query = URI.encode_www_form({})

loop do
    request = Net::HTTP::Get.new(uri.request_uri)
    request['Ocp-Apim-Subscription-Key'] = '<your key>'
    response = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http|
        http.request(request)
    end
    puts response.read_body
    response_msg = response.read_body
    break if response_msg.include?("Succeeded") or response_msg.include?("Failed")
    sleep 20
end

puts response.message
puts response.read_body
