[GitHub] [dubbo-go] 578157900 opened a new issue, #2302: restful protocol transport dial cause io timeout
578157900 opened a new issue, #2302:
URL: https://github.com/apache/dubbo-go/issues/2302
### Environment
<!--
- Server: Dubbo-go, v3.0.5
- Client: Dubbo-go, v3.0.5
- Protocol: Triple
- Registry: Nacos, v2.0.0
-->
- Client: Dubbo-go, v1.5.9
- Protocol: rest
- Registry: zookeeper
### Issue description
<!-- Here is a brief description about the issue. -->
https://github.com/apache/dubbo-go/blob/main/protocol/rest/client/client_impl/resty_client.go#L59
`
DialContext: func(_ context.Context, network, addr string) (net.Conn, error) {
c, err := net.DialTimeout(network, addr, restOption.ConnectTimeout)
if err != nil {
return nil, err
}
err = c.SetDeadline(time.Now().Add(restOption.RequestTimeout))
if err != nil {
return nil, err
}
return c, nil
},
`
http连接池复用tcp连接时，因为设置了deadline，resp未返回直接抛出io timeout。

`
func NewRestyClient(restOption *client.RestOptions) client.RestClient {
client := resty.New()
client.SetTransport(
&http.Transport{
DialContext: (&net.Dialer{
Timeout: restOption.ConnectTimeout,
}).DialContext,
IdleConnTimeout: 90 * time.Second,
}).SetTimeout(restOption.RequestTimeout)
return &RestyClient{
client: client,
}
}
`
1. 通过配置IdleConnTimeout超时来回收空闲链接。
2. 通过client.SetTimeout来设置每次请求的超时时间。
