Question

我应该在哪里对我的POST请求数据进行URL编码？对于每个参数，还是整个查询行？

例如，我有这段代码：

@VIEWSTATE = url_encode(@VIEWSTATE)
data = ("__EVENTTARGET=&__EVENTARGUMENT=&__LASTFOCUS=&__VIEWSTATE=#{@VIEWSTATE}&__EVENTVALIDATION=#{@EVENTVALIDATION}&=ctl0.......
headers = {
  'Cookie' => cookie,
***
}

resp, data = http.post(path, data, headers)

是对的，还是我必须写的：

@VIEWSTATE = @VIEWSTATE
    data = url_encode("__EVENTTARGET=&__EVENTARGUMENT=&__LASTFOCUS=&__VIEWSTATE=#{@VIEWSTATE}&__EVENTVALIDATION=#{@EVENTVALIDATION}&=ctl0.......
    headers = {
      'Cookie' => cookie,
    ***
    }

    resp, data = http.post(path, data, headers)

哪个是对的，哪个更好？

我通常喜欢使用URI's encode_www_form来获取数组或名称/值对的散列。这是the documentation的示例：

require 'uri'

URI.encode_www_form([["q", "ruby"], ["lang", "en"]])
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => "ruby", "lang" => "en")
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => ["ruby", "perl"], "lang" => "en")
#=> "q=ruby&q=perl&lang=en"
URI.encode_www_form([["q", "ruby"], ["q", "perl"], ["lang", "en"]])
#=> "q=ruby&q=perl&lang=en"
