How can I catch 410 error from `postToConnection` call via golang aws sdk?
问题
我正在使用AWS的websocket apigateway来管理websocket连接。有时候连接会断开，但@disconnect路由没有被触发。在这种情况下，postToConnection API调用会返回410错误。
我正在使用golang的sdk github.com/aws/aws-sdk-go-v2/service/apigatewaymanagementapi。postToConnection API返回PostToConnectionOutput, error。我该如何判断错误是否为410错误？

你可以检查返回的错误是否是GoneException类型。
请参阅https://aws.github.io/aws-sdk-go-v2/docs/handling-errors/
import(
api "github.com/aws/aws-sdk-go-v2/service/apigatewaymanagementapi"
apitypes "github.com/aws/aws-sdk-go-v2/service/apigatewaymanagementapi/types"
)
func main() {
svc := api.New(api.Options{
Region: "your-region",
})
output, err := svc.PostToConnection(ctx, &api.PostToConnectionInput{
ConnectionId: aws.String("your-connection-id"),
})
if err != nil {
var gne *apitypes.GoneException
if errors.As(err, &gne) {
log.Println("error:", gne.Error())
}
return
}
}
英文:
You can check the returned error is a type of GoneException
See https://aws.github.io/aws-sdk-go-v2/docs/handling-errors/
import(
api "github.com/aws/aws-sdk-go-v2/service/apigatewaymanagementapi"
apitypes "github.com/aws/aws-sdk-go-v2/service/apigatewaymanagementapi/types"
)
func main() {
svc := api.New(api.Options{
Region: "your-region",
})
output, err := svc.PostToConnection(ctx, &api.PostToConnectionInput{
ConnectionId: aws.String("your-connection-id"),
})
if err != nil {
var gne *apitypes.GoneException
if errors.As(err, &gne) {
log.Println("error:", gne.Error())
}
return
}
}
