See more DNS Examples

Shows how to perform a DNS query to retrieve TXT records.

Note: This example requires Chilkat v9.5.0.96 or later.

Go

    success := false

    dns := chilkat.NewDns()

    json := chilkat.NewJsonObject()
    json.SetEmitCompact(false)

    success = dns.Query("TXT","x.com",json)
    if success == false {
        fmt.Println(dns.LastErrorText())
        dns.DisposeDns()
        json.DisposeJsonObject()
        return
    }

    fmt.Println(*json.Emit())
