通常来说是不会超时的, 我们自己本身就需要对服务器做测试,上面的问题来自下面这个场景
因刚开始部署cce 给的cpu是0.25所以加载会特别慢 特别是第一次访问服务的时候 他需要加载其他服务的契约,导致了超时,这个时候我们再发现这个问题

超时的情况下会关闭连接， chrome会连续发送多次请求，是浏览器的问题。 参考： https://stackoverflow.com/questions/4460661/what-to-do-with-chrome-sending-extra-requests

感谢!!! 我这边的解决方案是 做一个handler 判断是否是 408 超时异常,如果是408 我将他转为 500或者其他 来让浏览器不去处理超时重试,您看这个方案可以吗? 或者有没有更好的建议

你提供的日志看不出来是重试，也不像是启用了java-chassis提供的重试功能。 估计得调试分析下重试是如何发生的，建议用个简单DEMO先验证分析下失败过程。

现在有网关A 和 服务B 网关A 我设置了 `servicecomb:

然后过了 6.04秒之后 报错

也就是用了浏览器调用时网关会被调用三次之后 抛出超时异常 但是看浏览器控制台的请求记录就是一个
然后我使用postman测试时 就只调用了一次 然后返回超时 花费的时间时2s 也就是我设置的超时时间
总结: postman 是希望的结果,就是浏览器出现的情况没理解是什么问题
补充: 使用浏览器的 ajax请求的时候 也是一样的问题

现在有网关A 和 服务B 网关A 我设置了 `servicecomb:
request:
timeout: 2000` 然后我使用浏览器地址栏里面调用接口C (是走网关的,然后我睡眠了60秒) 的时候 报如下错

然后过了 6.04秒之后 报错
`{
"message": "Request Timeout."
}`
也就是用了浏览器调用时网关会被调用三次之后 抛出超时异常 但是看浏览器控制台的请求记录就是一个
然后我使用postman测试时 就只调用了一次 然后返回超时 花费的时间时2s 也就是我设置的超时时间
总结: postman 是希望的结果,就是浏览器出现的情况没理解是什么问题
补充: 使用浏览器的 ajax请求的时候 也是一样的问题

我这边创建一个 全局的异常处理 InvocationException 捕捉这个异常 就不会出现那个情况了

通常来说是不会超时的, 我们自己本身就需要对服务器做测试,上面的问题来自下面这个场景
因刚开始部署cce 给的cpu是0.25所以加载会特别慢 特别是第一次访问服务的时候 他需要加载其他服务的契约,导致了超时,这个时候我们才发现这个问题

> java-chassis提供的重试功能 对于重试场景 会有重试线程处理 retry-pool-thread-
我遇到的这个情况该如何处理呢

简单的说就是浏览器通过网关调用服务的接口,当这个服务处理超时的时候(业务代码还是在处理,只是处理的时间长) 网关会再次发起调用(这里我不知道是不是浏览器发起的,但是浏览器的后台就是一次记录) 就导致 insert 的业务发生了多次(本该是一次的)
