从黑莓模拟器打开http连接时出现问题
||
从模拟器打开简单的HttpConnection时遇到了麻烦，我已经将deviceside = true后缀附加到了我的网址中，但是仍然无法正常工作，我收到了带有响应代码的空httpconnection的0。这是给我问题的代码：
public void readUrl(){
HttpConnection conn=null;
try {
conn = (HttpConnection) Connector.open(\"http://www.google.com;deviceside=true\");
conn.setRequestMethod(\"GET\");
if(conn.getResponseCode()==HttpConnection.HTTP_OK){
System.out.println(\"Create connection sucessfully\");
}
} catch (ConnectionNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
DataInputStream din=null;
ByteVector responseBytes=null;
try {
din = conn.openDataInputStream();
responseBytes = new ByteVector();
int i = din.read();
while (-1 != i) {
responseBytes.addElement((byte) i);
i = din.read();
}
} catch (IOException e) {
//TODO: HANDLE EXCEPTIONS
e.printStackTrace();
}
responseBytes.toArray();
没有找到相关结果

public StreamConnection openConnection(){ StreamConnection conn=null; try { conn = (StreamConnection) Connector.open(url+\";deviceside=true\"); //conn.setRequestMethod(httpMethod); } catch (ConnectionNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (IllegalArgumentException e) { e.printStackTrace(); } return conn; }din = conn.openDataInputStream(); responseBytes = new ByteVector(); int i = din.read(); while (-1 != i) { responseBytes.addElement((byte) i); i = din.read(); }
