我正在向服务器发送POST请求。以下用于PC应用程序的java代码,但不适用于我的Android应用程序。添加了Iternet权限,因此,发送此帖子需要做些什么,以及我必须使用哪些其他方法和库来替换Android的此代码?
String hostname = "xxxxxxx.box";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
Socket sock = new Socket(addr, port);
String SID = new classSID("xxxxxx").obtainSID();
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(sock.getOutputStream(),"UTF-8"));
String str = "enabled=on&username="+givenName+"&email="+givenEmail+"&password="+givenPassword+"&frominternet=on&box_admin_rights=on&phone_rights=on&homeauto_rights=on&uid=&sid="+SID+"&apply=";
////////////////////////////////////////////////////////////////////////////////////////////
wr.write("POST /system/boxuser_edit.lua HTTP/1.1");
wr.write("Host: xxxxxx:80" + "\r\n");
wr.write("Accept: text/html" + "\r\n");
wr.write("Keep-Alive: 300" + "\r\n");
wr.write("Connection: Keep-Alive" + "\r\n");
wr.write("Content-Type: application/x-www-form-urlencoded"+"\r\n");
wr.write("Content-Length: "+str.length()+"\r\n");
wr.write("\r\n");
wr.write(str+"\r\n");
wr.flush();
////////////////////////////////////////////////////////////////////////////////////////////
BufferedReader rd = new BufferedReader(new InputStreamReader(sock.getInputStream(),"UTF-8"));
String line;
while((line = rd.readLine()) != null)
Log.v("Response", line);
wr.close();
rd.close();
sock.close();
}

试试这个:并考虑使用IP而不是主机名,因为您的Android设备可能无法解析本地主机名
private static final String UTF_8 = "UTF-8";
/**

* : the host name or IP<br/>
* @param webService
* : the web service name<br/>
* @param classOrEndPoint
* : the file or end point<br/>

* : the parameters to be sent in the message body

问题在于在端口80上创建套接字。您需要root权限才能访问端口&lt; android中的1024。见issue
