我尝试通过发出获取请求从 kibana 服务器获取 csv 数据。在此服务器向我发送带有数据的响应后,我编写csv文件并保存在某个地方。
每次 csv 文件都有一行“挂起”。
Kibana日志显示状态代码503
但是如果我把网址放在浏览器中,我可以得到带有正确数据的csv文件。
可能我需要等待更多来自基巴纳的回应。
从我的角度来看,问题就在下一个:服务器可以向我发送带有单行“待处理”的响应,这意味着它需要更多时间来准备正确的响应。
我试图增加客户时间,但它不起作用
client := http.Client{
Timeout: 10 * time.Second,
}
接下来是带有go例程和通道/等待组的想法:他们强制Get请求等待获取正确的数据,而不是“待定”和503状态代码
