用于Facebook Api的Ruby中的卷曲请求

Question

我正在尝试用curb gem进行卷曲调用，相当于：

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

到目前为止我的代码看起来像：

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，作为回应，我得到了这个：

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

有人能解释一下我做错了什么吗？ 谢谢！

你也可以使用这样的系统调用：

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

result将保存系统调用的输出。 对于更复杂的http请求，您可能想看一下法拉第（ https://github.com/lostisland/faraday ）
