我正在使用httparty进行一系列API调用.前两个API调用成功,但第三个失败.它暂停约60秒(默认超时时间),然后返回此错误：

我的问题是为什么会发生这种情况？这个错误是否表示API的错误,还是有什么可以做的呢？
我的代码：
这是工作的电话：
url = HTTParty.get("https://dev.test.com#{call}",:basic_auth => auth,:headers => {'Accept' => 'application/json' } )
这是不起作用的电话：
url = HTTParty.get("https://dev.test.com#{call}",:headers => {'Accept' => 'application/json' } )
唯一改变的是实际的呼叫,但根据API文档,它们都是有效的呼叫.
解决方法
从Ruby文档：
http://ruby-doc.org/stdlib-2.1.2/libdoc/net/http/rdoc/Net/HTTP.html
Number of seconds to wait for one block to be read (via one read(2) call).
Any number may be used,including Floats for fractional seconds.
If the HTTP object cannot read data in this many seconds,
it raises a Net::ReadTimeout exception. The default value is 60 seconds.
什么叫？服务端点是否不同？您是否通过记录进行分页？ API通常限制呼叫者阻止DDOS攻击.您可以尝试在某些重试逻辑中添加api调用或添加一些睡眠代码.
