用於Facebook Api的Ruby中的卷曲請求

Question

我正在嘗試用curb gem進行卷曲調用，相當於：

curl \
  -F 'name=My new CA' \
  -F 'subtype=CUSTOM' \
  -F 'description=People who bought from my website' \
  -F 'access_token=<ACCESS_TOKEN>' \
  https://graph.facebook.com/v2.5/act_<AD_ACCOUNT_ID>/customaudiences

到目前為止我的代碼看起來像：

cr = Curl::Easy.http_post("https://graph.facebook.com/v2.5/act_XXXXXXXXXXXXXXX/customaudiences?access_token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") do |curl|
    curl.headers['name']='My new CA'
    curl.headers['subtype']='CUSTOM'
    curl.headers['description']='People who bought from my website'
    curl.headers['access_token']='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
end

   pp cr.body_str

但是，作為回應，我得到了這個：

 => "{\"error\":{\"message\":\"(#100) Missing parameter(s): subtype\",\"type\":\"OAuthException\",\"code\":100,\"fbtrace_id\":\"BOd\\/mmhQkkP\"}}"

有人能解釋一下我做錯了什么嗎？ 謝謝！

你也可以使用這樣的系統調用：

name = "something"
url = "http://www.example.com"
result = `curl -F 'name=#{name}' #{url}`

result將保存系統調用的輸出。 對於更復雜的http請求，您可能想看一下法拉第（ https://github.com/lostisland/faraday ）
