在下文中一共展示了Query類的3個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的Golang代碼示例。
示例1: processQuery
func (d *driver) processQuery(q *serf.Query) {
logrus.Debugf("Received query name:%s, payload:%s\n", q.Name,
string(q.Payload))
var nid, ipStr string
if _, err := fmt.Sscan(string(q.Payload), &nid, &ipStr); err != nil {
fmt.Printf("Failed to scan query payload string: %v\n", err)
}
peerMac, peerIPMask, vtep, err := d.peerDbSearch(nid, net.ParseIP(ipStr))
if err != nil {
return
}
q.Respond([]byte(fmt.Sprintf("%s %s %s", peerMac.String(), net.IP(peerIPMask).String(), vtep.String())))
}示例2: sendQuery
// sendQuery is used to send a single query event
func (es *eventStream) sendQuery(q *serf.Query) error {
id := es.client.RegisterQuery(q)
header := responseHeader{
Seq: es.seq,
Error: "",
}
rec := queryEventRecord{
Event: q.EventType().String(),
ID: id,
LTime: q.LTime,
Name: q.Name,
Payload: q.Payload,
}
return es.client.Send(&header, &rec)
}示例3: RegisterQuery
// RegisterQuery is used to register a pending query that may
// get a response. The ID of the query is returned
func (c *IPCClient) RegisterQuery(q *serf.Query) uint64 {
// Generate a unique-per-client ID
id := c.nextQueryID()
// Ensure the query deadline is in the future
timeout := q.Deadline().Sub(time.Now())
if timeout < 0 {
return id
}
// Register the query
c.queryLock.Lock()
c.pendingQueries[id] = q
c.queryLock.Unlock()
// Setup a timer to deregister after the timeout
time.AfterFunc(timeout, func() {
c.queryLock.Lock()
delete(c.pendingQueries, id)
c.queryLock.Unlock()
})
return id
}
