关于RestClient::RequestTimeout请求超时

[wikimo]

关于请求超时问题，想请问下得如何排除，设置了timeout也不能很好地解决，服务器配置低容易timeout么？

[lanrion]

捕捉Timeout的异常，然后做while。

[wikimo]

Timeout 设置较长是否可行，目前设置还不算太长，while 相当于死循环了 @lanrion

[lanrion]

Timeout你设置长点试试； while是不是死循环，由你代码决定，搞个计数器，每次重新while sleep一下试试。 请求超时，难道你的是国外的VPS？

[wikimo]

思路大概了解了，就是捕捉异常，失败重试。

阿里云，不过机器配置比较低，1CPU，1G内存，5MB带宽 @lanrion

[wikimo]

另外总是会在一些奇怪的地方报错，是服务器的问题还是别的什么问题，cpu率，内存也够用的 @lanrion

[lanrion]

为什么提问题的人，都喜欢只贴一部分的错误信息，然而并没有什么用。 请提供完整的错误信息。

[wikimo]

不好意思，可能上下文信息有点少，跑了3个thin在上面，cpu率不高，内存通过vmstat 查看，swap并未使用，用ab测过并发ab -n 800 -c 250 ，fail 为0，都能成功。主要是有时候成功，有时候报错，这个比较麻烦，通过跟踪感觉都是在这个gem http 请求的地方断掉了，或者没返回，服务器带宽5M 阿里云。 @lanrion

这段异常还是看不出有什么错误，能不能直接把最顶层的错误信息贴过来？我指的是全部，你可以把敏感信息用其他字符替换。

[wikimo]

这已经都是顶层了，Rails.logger.level = 0。

另外调整timeout/open_timeout 到1000，关闭verify_ssl后，似乎有所好转，但是不知是否还有隐患

@lanrion

[lanrion]

我也是醉了，貌似加了SSL之后，经常有人问timeout，先去除吧。

[ChocolateAceCream]

是不是有防火墙所以ssl老超时-------- 原始邮件 --------主题：Re: [weixin_authorize] 关于RestClient::RequestTimeout请求超时 (#77)发件人：wikimo 收件人：lanrion/weixin_authorize 抄送：这已经都是顶层了，Rails.logger.level = 0。

[wikimo]

防火墙确实开了，现在是时好时坏，不稳定，所以感觉就比较难排查 @ChocolateAceCream

关闭ssl后，暂时还算稳定 @lanrion

[lanrion]

@wikimo @ChocolateAceCream 这个项目的CI，跑在国外，一般都会有Timeout出现，所以每次本地跑通了，都是直接忽略CI 超时。。

[lanrion]

先关闭了。
