Call and response: your first Bing Web Search query in Ruby

The Bing Web Search API provides a experience similar to Bing.com/Search by returning search results that Bing determines are relevant to the user's query. The results may include Web pages, images, videos, news, and entities, along with related search queries, spelling corrections, time zones, unit conversion, translations, and calculations. The kinds of results you get are based on their relevance and the tier of the Bing Search APIs to which you subscribe.

This article includes a simple console application that performs a Bing Web Search API query and displays the returned raw search results, which are in JSON format. While this application is written in Ruby, the API is a RESTful Web service compatible with any programming language that can make HTTP requests and parse JSON.

Prerequisites

You will need Ruby 2.4 or later to run the example code.

You must have a Cognitive Services API account with Bing Search APIs. The free trial is sufficient for this quickstart. You need the access key provided when you activate your free trial, or you may use a paid subscription key from your Azure dashboard.

Running the application

To run this application, follow these steps.

  1. Create a new Ruby project in your favorite IDE or editor.
  2. Add the provided code.
  3. Replace the accessKey value with an access key valid for your subscription.
  4. Run the program.
require 'net/https'
require 'uri'
require 'json'

# **********************************************
# *** Update or verify the following values. ***
# **********************************************

# Replace the accessKey string value with your valid access key.
accessKey = "enter key here"

# Verify the endpoint URI.  At this writing, only one endpoint is used for Bing
# search APIs.  In the future, regional endpoints may be available.  If you
# encounter unexpected authorization errors, double-check this value against
# the endpoint for your Bing Web search instance in your Azure dashboard.

uri  = "https://api.cognitive.microsoft.com"
path = "/bing/v7.0/search"

term = "Microsoft Cognitive Services"

if accessKey.length != 32 then
    puts "Invalid Bing Search API subscription key!"
    puts "Please paste yours into the source code."
    abort
end

uri = URI(uri + path + "?q=" + URI.escape(term))

puts "Searching the Web for: " + term

request = Net::HTTP::Get.new(uri)
request['Ocp-Apim-Subscription-Key'] = accessKey

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

puts "\nRelevant Headers:\n\n"
response.each_header do |key, value|
    # header names are coerced to lowercase
    if key.start_with?("bingapis-") or key.start_with?("x-msedge-") then
        puts key + ": " + value
    end
end

puts "\nJSON Response:\n\n"
puts JSON::pretty_generate(JSON(response.body))

JSON response

A sample response follows. To limit the length of the JSON, only a single result is shown, and other parts of the response have been truncated.
