cURL Error 28:操作超时问题解析
在进行网络请求的过程中,我们常常会遇到各种各样的错误。其中,cURL error 28: Operation timed out after 15001 milliseconds with 0 bytes received
是一个常见的错误信息。这个错误提示意味着使用cURL工具执行的HTTP请求在设定的时间内(这里是15001毫秒)没有完成,并且没有接收到任何数据返回。
什么是cURL?
cURL是一个强大的命令行工具,用于从或向服务器传输数据。它支持多种协议,包括但不限于HTTP、HTTPS、FTP等。通过cURL,用户可以方便地发送GET、POST等类型的请求来获取网页内容、下载文件或是上传数据等。
为什么会出现Error 28?
- 网络延迟:如果目标服务器响应非常慢或者网络连接不稳定,则可能导致请求超时。
- 服务器端问题:服务器可能因过载而无法及时处理请求,也可能是遇到了其他技术问题导致服务中断。
- 客户端配置不当:如设置的超时时间太短不足以让请求正常完成,或者是防火墙等安全设置阻止了请求。
- DNS解析失败:域名服务器未能成功解析目标网址,这也会导致请求无法到达目的地。
如何解决这个问题?
- 检查网络状况:首先确认自己的网络是否稳定,尝试访问其他网站以测试当前网络环境。
- 调整超时设置:可以通过修改cURL命令中的
--connect-timeout
和--max-time
参数值来增加等待时间。--connect-timeout <seconds>
指定连接建立前的最大等待时间;--max-time <seconds>
设置整个操作的最大允许时间。
- 验证服务器状态:查看是否有来自服务器方的通知表明正在进行维护工作或其他异常情况。
- 优化本地环境:关闭不必要的程序和服务,减少对带宽资源的竞争;检查并适当调整防火墙及安全软件设置,确保它们不会干扰正常的网络通信。
- 联系技术支持:如果上述方法都无法解决问题,那么最好直接联系相关服务提供商的技术支持寻求帮助。
总之,面对cURL error 28
这类超时错误时,需要从多个角度综合分析原因,并采取相应措施逐一排查直至找到真正的问题所在。希望这篇文章能为你理解和解决此类问题提供一定参考价值。

Getting timeout errors too. Their servers must be overloaded right now.
Ugh same issue here! Was trying to upload a project and got the same curl error. So frustrating 😤
Works fine for me now. Maybe they fixed the servers?
I love Kaiber’s tools but this timeout issue is making me reconsider my subscription…
Pro tip: try again later. Their API gets shaky during peak hours.
This is why I always save locally before uploading. Learned my lesson the hard way!
Anyone know if they have status page for server issues?
Just refreshed and it worked. Might have been temporary 🤞
Their support team is actually pretty responsive if you tweet at them about this.
