通過Net :: HTTP在Ruby中發送http post請求

Question

我正在向Web服務發送帶有自定義標頭的請求。

require 'uri'
require 'net/http'

uri = URI("https://api.site.com/api.dll")
https = Net::HTTP.new(uri.host, uri.port)
https.use_ssl = true
headers = 
{
    'HEADER1' => "VALUE1",
    'HEADER2' => "HEADER2"
}

response = https.post(uri.path, headers) 
puts response

它沒有用，我收到的錯誤是：

/usr/lib/ruby/1.9.1/net/http.rb:1932:in `send_request_with_body': undefined method `bytesize' for #<Hash:0x00000001b93a10> (NoMethodError)

我該如何解決這個問題？

PS Ruby 1.9.3

Answer 1

Net::HTTP#post的第二個參數需要是一個包含要發布的數據的String （通常是表單數據），標題將位於可選的第三個參數中。

Answer 2

試試這個：

有關詳細文檔，請查看： http ： //www.rubyinside.com/nethttp-cheat-sheet-2940.html

require 'uri'
require 'net/http'

uri = URI('https://api.site.com/api.dll')
https = Net::HTTP.new(uri.host, uri.port)
https.use_ssl = true

request = Net::HTTP::Post.new(uri.path)

request['HEADER1'] = 'VALUE1'
request['HEADER2'] = 'VALUE2'

response = https.request(request)
puts response

Answer 3

正如qqx所提到的， Net::HTTP#post的第二個參數需要是一個String

幸運的是，有一個簡潔的函數將哈希轉換為所需的字符串：

response = https.post(uri.path, URI.encode_www_form(headers))
