我正在尝试获取查询的 Bing 搜索结果。我正在使用 Ruby 和curb,但无法从 API 服务器返回任何结果。我总是得到400 Bad Request

这就是 API 文档对 PHP 所说的 在此处输入图像描述

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...

会出什么问题?

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返回一个带换行符的字符串。strict_encode64会避免这个问题。(您也可以只删除换行符。)
  2. 我无法将查询参数直接放在 URL 中。我只是将参数移到哈希中,这可能是更典型的方法。
  3. 编辑)我还取出了两个虚假标题“request_fulluri”和“ignore_errors”。我不认为这些是 Perl 代码中的实际标题。我没有尝试将它们留在里面,所以也许它们是无害的,但我认为您不需要它们。
