Question

Manualy完美卷曲工作：

curl https://www.googleapis.com/urlshortener/v1/url \
    -H 'Content-Type: application/json' \
    -d '{"longUrl": "http://www.rubyinside.com/"}'

当我尝试在Net :: Http：

中创建它时

require "net/https"
require "uri"
uri = URI.parse("https://www.googleapis.com/urlshortener/v1/url")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(uri.path)
request["Content-Type"] = "application/json"
request.set_form_data({"longUrl" => "http://www.rubyinside.com/"})
response = http.request(request)
puts response.body

但是回复失败了：

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "parseError",
    "message": "This API does not support parsing form-encoded input."
   }
  ],
  "code": 400,
  "message": "This API does not support parsing form-encoded input."
 }
}
 => nil

I see an another issue but seem does not work

This httparty sample code work but i want use net_http

Answer 1

您必须以json的形式发送数据，而不是按照您尝试的方式编码。尝试更改您的代码：

....
require 'json'

....
request.body = {"longUrl" => "http://www.rubyinside.com/"}.to_json

Answer 2

Ruby不是我的领域，但我最近在C＃中做过类似的事情。根据Ruby-Doc.org的方法，.set_form_data将内容类型标题设置为“application / x-www-form-urlencoded”，这将覆盖您将其设置为JSON。

像Fiddler2这样的工具在破译正在发生的事情方面提供了很大的帮助。
