6.2、Android中向Internet发送xml数据

向Internet发送xml数据

利用HttpURLConnection对象,我们可以向网络发送xml数据.

StringBuilderxml=newStringBuilder();

xml.append("<?xmlversion=\"1.0\"encoding=\"utf-8\"?>");

xml.append("<M1V=10000>");

xml.append("<UI=1D=\"N73\">中国</U>");

xml.append("</M1>");

byte[]xmlbyte=xml.toString().getBytes("UTF-8");

URLurl=newURL("http://localhost:8080/itcast/contanctmanage.do?method=readxml");

HttpURLConnectionconn=(HttpURLConnection)url.openConnection();

conn.setConnectTimeout(5*1000);

conn.setDoOutput(true);//允许输出

conn.setUseCaches(false);//不使用Cache

conn.setRequestMethod("POST");

conn.setRequestProperty("Connection","Keep-Alive");//维持长连接

conn.setRequestProperty("Charset","UTF-8");

conn.setRequestProperty("Content-Length",String.valueOf(xmlbyte.length));

conn.setRequestProperty("Content-Type","text/xml;charset=UTF-8");

DataOutputStreamoutStream=newDataOutputStream(conn.getOutputStream());

outStream.write(xmlbyte);//发送xml数据

outStream.flush();

if(conn.getResponseCode()!=200)thrownewRuntimeException("请求url失败");

InputStreamis=conn.getInputStream();//获取返回数据

Stringresult=readAsString(is,"UTF-8");

outStream.close();
