Bing搜索API通过Ruby限制

Question

我正在尝试获取Bing搜索结果以进行查询。我正在使用Ruby和curb，但无法从API服务器获得任何结果。我总是得到400 Bad Request。

这是API文档对PHP的说法

这是我的代码：

require 'curb'
require 'base64'

acctKey = "something"
authKey = Base64.encode64("#{acctKey}:#{acctKey}")
http = Curl.get("https://api.datamarket.azure.com/Bing/Search/Web?$format=json&Query=%27Xbox%27") do |http|
    http.headers['Authorization'] = "Basic #{authKey}"
    http.headers['request_fulluri'] = true
    http.headers['ignore_errors'] = false
    http.verbose = true
end

结果如下：

* About to connect() to api.datamarket.azure.com port 443 (#0)
*   Trying 157.55.194.132...

会出现什么问题？

Answer 1

试试这个：

require 'curb'
require 'base64'

acctKey = "<YOUR KEY>"
authKey = Base64.strict_encode64("#{acctKey}:#{acctKey}")
http = Curl.get("https://api.datamarket.azure.com/Bing/Search/Web", {:$format => "json", :Query => "'Xbox'"}) do |http|
    http.headers['Authorization'] = "Basic #{authKey}"
    http.verbose = true
end

puts http.body_str

注意几件事：

1. Base64.encode64返回带换行符的字符串。 strict_encode64会避免这个问题。 （您也可以删除换行符。）
2. 我将查询参数直接放在URL中时遇到了麻烦。我只是将参数移到哈希中，这可能是更典型的方法。
3. （ EDIT ）我还拿出了两个伪造的标题“request_fulluri”和“ignore_errors”。我不认为这些是Perl代码中的实际标头。我没有尝试让他们进去，所以也许他们是无害的，但我认为你不想要他们。
