Withings :回调URL要么未知要么无效

Question

我正在尝试在withings中设置一个通知(使用withings simplificator)。我总是会得到这个错误，不管我输入了什么URL，或者我是否对它进行了编码：

irb(main):013:0> user.subscribe_notification('http://foo.bar.com', 'test subscription')
Withings::ApiError: The callback URL 'http://foo.bar.com' is either unknown or invalid - Status code: 293
  from /app/vendor/bundle/ruby/2.2.0/gems/simplificator-withings-0.7.0/lib/withings/connection.rb:80:in `verify_response!'

有没有人遇到过这种情况，并有解决办法？

更新1:

因此，我尝试不使用withings简化器gem：

API_KEY       = '123'
API_SECRET    = '456'
USER_ID       = '789'
USER_KEY      = 'abc'
USER_SECRET   = 'def'
CONFIGURATION = {               site: 'https://oauth.withings.com',
                  request_token_path: '/account/request_token',
                   access_token_path: '/account/access_token',
                      authorize_path: '/account/authorize',
                         http_method: :get,
                              scheme: :query_string
                }

@consumer = OAuth::Consumer.new API_KEY, API_SECRET, CONFIGURATION

@access_token = OAuth::AccessToken.new @consumer, USER_KEY, USER_SECRET

url = ERB::Util.url_encode("www.foo.bar/trigger")
comment = ERB::Util.url_encode("Trigger")
response = @access_token.get("https://wbsapi.withings.net/notify?action=subscribe&userid=#{USER_ID}&callbackurl=#{url}&comment=#{comment}")
JSON.parse(response.body)

同样的错误：

irb(main):051:0>   JSON.parse(response.body)
=> {"status"=>293}

我做错了什么？

您的通知端点将执行两个操作：

1. 它将响应测试请求响应(注册时它将检查您的URL是否存在)。您将收到带有空body对象的呼叫。如果它没有userid，它不是一个数据通知，所以您必须响应状态为200与空体；
2. 成功注册后，您将收到数据警报。这一次，您可以通过业务逻辑来处理。
