我是一个非常新的黑莓应用程序开发和面临的一个大问题,在集成Web服务在我的黑莓应用程序。我必须在应用程序中使用Post Web服务,甚至没有找到一个教程,解释如何在黑莓整合Web服务。请在这方面找人帮忙。我执行了这个链接上给出的例子。当我尝试打开链接浏览器时,互联网可用,但它没有通过我的应用程序连接到Web服务。
try this -
try {
httpURL="http://google.co.in/";
if ((WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)
&& RadioInfo
.areWAFsSupported(RadioInfo.WAF_WLAN)) {
httpURL += ";interface=wifi";
}else if (TransportInfo.isTransportTypeAvailable(TransportInfo.TRANSPORT_BIS_B) && TransportInfo.hasSufficientCoverage(TransportInfo.TRANSPORT_BIS_B)) {
System.out.println("BIS CONNECTION-------------------");
// Holder.connectionInterface=";deviceside=false;ConnectionType=mds-public";
httpURL += ";deviceside=false;ConnectionType=mds-public";
}
//Dialog.alert(httpURL);
HttpConnection httpConn;
httpConn = (HttpConnection) Connector.open(httpURL);
httpConn.setRequestMethod(HttpConnection.POST);
DataOutputStream _outStream = new DataOutputStream(httpConn.openDataOutputStream());
byte[] request_body = httpURL.getBytes();
for (int i = 0; i < request_body.length; i++) {
_outStream.writeByte(request_body[i]);
}
DataInputStream _inputStream = new DataInputStream(
httpConn.openInputStream());
StringBuffer _responseMessage = new StringBuffer();
int ch;
while ((ch = _inputStream.read()) != -1) {
_responseMessage.append((char) ch);
}
String res = (_responseMessage.toString());
responce = res.trim();
//Dialog.alert(responce);
httpConn.close();
}catch (Exception e) {
Dialog.alert("Error -"+e.toString());
}
在发布之前请用google搜索"Blackberry+httppost",你会得到很多链接。另外,我建议一个对初学者有用的链接。听起来不错。
你还必须学习连接扩展,如"interface=wifi;deviceside=true"等。
