使用Python通过Azure API搜索Bing

如何使用关键词搜索Bing的图像？

我可以使用以下方式搜索Google：

import urllib2
import json

credentialGoogle = '' # Google credentials from: https://console.developers.google.com/
searchString = 'Xbox%20One'
top = 20
offset = 0
while offset < top:
    url = 'https://ajax.googleapis.com/ajax/services/search/images?' + 
          'v=1.0&q=%s&start=%d&userip=%s' % (searchString,offset,credentialGoogle)

    request = urllib2.Request(url)
    response = urllib2.urlopen(request)
    results = json.load(response)

    # process results

    offset += 4     # since Google API only returns 4 search results at a time

Bing的等价物是什么？据推测它开始于：

keyBing = ''        # Bing key from: https://datamarket.azure.com/account/keys
credentialBing = '' # same as key?
searchString = '%27Xbox+One%27'
top = 20
offset = 0

url = 'https://api.datamarket.azure.com/Bing/Search/Image?' + 
      'Query=%s&$top=%d&$skip=%d&$format=json' % (searchString,top,offset)

但凭证是如何设置的？

解决方法

keyBing = ''        # get Bing key from: https://datamarket.azure.com/account/keys
credentialBing = 'Basic ' + (':%s' % keyBing).encode('base64')[:-1] # the "-1" is to remove the trailing "n" which encode adds
searchString = '%27Xbox+One%27'
top = 20
offset = 0

url = 'https://api.datamarket.azure.com/Bing/Search/Image?' + 
      'Query=%s&$top=%d&$skip=%d&$format=json' % (searchString,offset)

request = urllib2.Request(url)
request.add_header('Authorization',credentialBing)
requestOpener = urllib2.build_opener()
response = requestOpener.open(request) 

results = json.load(response)

# process results
