[英]Ruby Net::HTTP 400 Bad Request
我正在嘗試使用http://www.nasdaqomxnordic.com/shares/listed-companies/nordic-large-cap抓取其數據。 這是我的代碼,使用Net :: HTTP發送獲取請求:
require 'net/http'
require 'uri'
def get_stocks()
uri = URI.parse('http://www.nasdaqomxnordic.com/aktier/listed-companies/stockholm')
response = Net::HTTP.get_response(uri)
puts response
end
get_stocks()
我測試過的其他站點效果很好,並以200:OK響應,但http://www.nasdaqomxnordic.com/shares/listed-companies/nordic-large-cap返回#<Net::HTTPBadRequest:0x00007ffe8f84ec30>
和我不明白為什么。
對於進一步的上下文, response.body
返回:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

我怎樣做才能得到200:OK
?
我認為您需要設置請求的User-Agent
屬性。 以下代碼有效。
require 'net/http'
require 'uri'
def get_stocks()
uri = URI.parse("http://www.nasdaqomxnordic.com/shares/listed-companies/nordic-large-cap")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
user_agent = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.86 Safari/537.36'
request.initialize_http_header({"User-Agent" => user_agent})
response = http.request(request)
puts response.inspect
end
get_stocks() # #<Net::HTTPOK 200 OK readbody=true>
您可以使用response.body
獲取響應正文
