域名注册在java中为Android [英] whois in java for Android
问题描述
我正在做的whois在Java中为Android培训关于流和TCP连接。
I'm making a whois in java for android to train about streams and tcp connections.
不过,我有一个问题。我有一个PHP脚本,我写了前一段时间我正尝试使Java中的相同。
But I have a problem. I have a php script, I wrote some time ago and I´m trying to make the same in java.
这是我的Java code:
this is my java code :
public String consultawhois(String domain,String tld)
{
String domquest = domain + "." + tld;
String resultado = "";
Socket theSocket;
String hostname = "whois.internic.net";
int port = 43;
try {
theSocket = new Socket(hostname, port, true);
Writer out = new OutputStreamWriter(theSocket.getOutputStream());
out.write(domquest + "\r\n");
out.flush();
DataInputStream theWhoisStream;
theWhoisStream = new DataInputStream(theSocket.getInputStream());
String s;
while ((s = theWhoisStream.readLine()) != null) {
resultado = resultado + s + "\n";
}
}
catch (IOException e) {
}
return resultado;
}
服务器的答案是不正确的,我认为问题是,我要送一个坏的查询。我送的查询是dominio.com \\ r \\ n,并在我的PHP的whois code,它完美的作品。
The answer of the server is not correct and I think the problem is that I'm sending a bad query. The query I send is "dominio.com\r\n" and in my php whois code, it works perfectly.
推荐答案
看来,DNS查询多个记录相匹配。至少,这是我怎么际preT的响应。在返回的效应初探应该可以看到以下行:
It seems that the DNS query matches multiple records. At least, that is how I interpret the response. In the returned reponse you should see the following line:
要挑出一个记录,以XXX,其中xxx是一个看它
上面显示的记录。如果记录是相同的,找一找
用= XXX来接收全屏显示为每个记录。
To single out one record, look it up with "xxx", where xxx is one of the of the records displayed above. If the records are the same, look them up with "=xxx" to receive a full display for each record.
所以,如果你prePEND与查询=只返回该记录的数据。下面为我工作。
So if you prepend the query with "=" it returns the data of that record only. The following worked for me.
public String consultawhois(String domain,String tld)
{
String domquest = domain + "." + tld;
String resultado = "";
Socket theSocket;
String hostname = "whois.internic.net";
int port = 43;
try {
theSocket = new Socket(hostname, port, true);
Writer out = new OutputStreamWriter(theSocket.getOutputStream());
out.write("="+domquest + "\r\n");
out.flush();
DataInputStream theWhoisStream;
theWhoisStream = new DataInputStream(theSocket.getInputStream());
String s;
while ((s = theWhoisStream.readLine()) != null) {
resultado = resultado + s + "\n";
}
}
catch (IOException e) {
}
return resultado;
}
有一点要考虑:使用英语的方法名,变量等,而不是西班牙语。它会让你的code更容易阅读国际。编程语言本身也使用英语单词。尽量避免英语的一个奇怪的组合和你的母语。
One thing to consider: Use English for method names, variables, etc. instead of Spanish. It will make your code easier to read internationally. The programming language itself also uses English words. Try to avoid a strange mix of English and your native language.
