Вы должны добавить все параметры соединения в ваш URL, используя HTTPConnetion.Создайте один пользовательский класс для проверки параметра соединения. ИСПОЛЬЗУЙТЕ приведенный ниже Custom Class.
public class HttpConnectionImpl
extends impl.javame.com.twitterapime.io.HttpConnectionImpl {
private static String appendConnectionParameters;
private static String connectionParameters;
private static ServiceRecord getWAP2ServiceRecord() {
String cid;
String uid;
ServiceBook sb = ServiceBook.getSB();
ServiceRecord[] records = sb.getRecords();
//
for (int i = records.length -1; i >= 0; i--) {
cid = records[i].getCid().toLowerCase();
uid = records[i].getUid().toLowerCase();
//
if (cid.indexOf("wptcp") != -1
&& uid.indexOf("wifi") == -1
&& uid.indexOf("mms") == -1) {
return records[i];
}
}
//
return null;
}
public static String getConnectionParams() {
String connParams = "";
//
if (connectionParameters != null) {
connParams = connectionParameters;
} else {
if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
connParams = ";interface=wifi"; //Connected to a WiFi access point.
} else {
int coverageStatus = CoverageInfo.getCoverageStatus();
//
if ((coverageStatus & CoverageInfo.COVERAGE_BIS_B) == CoverageInfo.COVERAGE_BIS_B) {
connParams = ";deviceside=false;ConnectionType=mds-public";
} else if ((coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
// Have network coverage and a WAP 2.0 service book record
ServiceRecord record = getWAP2ServiceRecord();
//
if (record != null) {
connParams = ";deviceside=true;ConnectionUID=" + record.getUid();
} else {
connParams = ";deviceside=true";
}
} else if ((coverageStatus & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
// Have an MDS service book and network coverage
connParams = ";deviceside=false";
}
}
//
if (appendConnectionParameters != null) {
connParams += appendConnectionParameters;
}
}
//
return connParams;
}
public static void setAppendConnectionParameters(String params) {
if (params != null && !params.startsWith(";")) {
params = ";" + params;
}
//
appendConnectionParameters = params;
}
public static void setConnectionParameters(String params) {
if (params != null && !params.startsWith(";")) {
params = ";" + params;
}
//
connectionParameters = params;
}
public void open(String url) throws IOException {
super.open(url + getConnectionParams());
}
}
. После интеграции с вышеприведенным классом вам нужно сделать один пакет с именем impl.javame.com.twitterapime.io и добавить следующий класс.1008 * `пакет impl.javame.com.twitterapime.io;импорт java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import javax.microedition.io.Connector;import com.twitterapime.io.HttpConnection;
открытый класс HttpConnectionImpl реализует HttpConnection {private javax.microedition.io.HttpConnection httpConn;
public void open(String url) throws IOException {
httpConn =
(javax.microedition.io.HttpConnection)
Connector.open(url, Connector.READ_WRITE, true);
}
public void close() throws IOException {
httpConn.close();
}
public int getResponseCode() throws IOException {
return httpConn.getResponseCode();
}
public InputStream openInputStream() throws IOException {
return httpConn.openInputStream();
}
public OutputStream openOutputStream() throws IOException {
return httpConn.openOutputStream();
}
public void setRequestMethod(String method) throws IOException {
httpConn.setRequestMethod(method);
}
public void setRequestProperty(String key, String value) throws IOException{
httpConn.setRequestProperty(key, value);
}
public String getRequestProperty(String key) throws IOException {
return httpConn.getRequestProperty(key);
}
public String getHeaderField(String name) throws IOException {
return httpConn.getHeaderField(name);
}
} `
Теперь выдолжны интегрировать еще два класса
- HttpConnection
- HttpResponsein
com.twitterapime.io пакет.
`пакет com.twitterapime.io;импорт java.io.IOException;import java.io.InputStream;import java.io.OutputStream;открытый интерфейс HttpConnection {public static final String GET = "GET";
public static final String POST = "POST";
public static final String HEAD = "HEAD";
public static final int HTTP_OK = 200;
public static final int HTTP_FORBIDDEN = 403;
public static final int HTTP_UNAVAILABLE = 503;
public static final int HTTP_NOT_MODIFIED = 304;
public static final int HTTP_BAD_REQUEST = 400;
public static final int HTTP_UNAUTHORIZED = 401;
public static final int HTTP_NOT_FOUND = 404;
public static final int HTTP_NOT_ACCEPTABLE = 406;
public static final int HTTP_INTERNAL_ERROR = 500;
public static final int HTTP_BAD_GATEWAY = 502;
public void open(String url) throws IOException;
public void close() throws IOException;
public int getResponseCode() throws IOException;
public InputStream openInputStream() throws IOException;
public OutputStream openOutputStream() throws IOException;
public void setRequestMethod(String method) throws IOException;
public void setRequestProperty(String key, String value) throws IOException;
public String getRequestProperty(String key) throws IOException;
public String getHeaderField(String name) throws IOException;
Bwlow - это класс HttpResponse`
`пакет com.twitterapime.io;
импорт java.io.ByteArrayOutputStream;импорт java.io.IOException;import java.io.InputStream;import java.io.UnsupportedEncodingException;
открытый финальный класс HttpResponse {private int code;
private String body;
private InputStream stream;
private HttpConnection conn;
HttpResponse(HttpConnection conn) throws IOException {
this.conn = conn;
code = conn.getResponseCode();
stream = conn.openInputStream();
}
public boolean wasSuccessful() {
return code >= 200 && code < 400;
}
public String getBodyContent() throws IOException {
return body != null ? body : (body = parseBody(stream));
}
public InputStream getStream() {
return stream;
}
public int getCode() {
return code;
}
public String getResponseField(String key) throws IOException {
return conn.getRequestProperty(key);
}
private String parseBody(InputStream in) throws IOException {
if (in == null) {
return null;
}
//
ByteArrayOutputStream out = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
//
for (int n; (n = in.read(buffer)) > 0;) {
out.write(buffer, 0, n);
}
//
try {
return new String(out.toByteArray(), "UTF-8");
} catch (UnsupportedEncodingException e) {
throw new IOException(e.getMessage());
}
}
} `
Используйте приведенный ниже метод для проверки вашего параметра подключения.Этот метод автоматически проверяет доступность подключения к вашему устройству и добавляет параметр подключения на основе вашего подключения.
protected HttpConnection getConnection(String url) throws IOException {
url += HttpConnectionImpl.getConnectionParams();
//
return (HttpConnection)Connector.open(url);
}
Указанный выше HttpConnection URL-адрес возврата метода с параметром подключения ... чем вы можете использовать это подключение в yout InputStreamи откройте любой URL, а также веб-сервис.
Надеюсь, это поможет вам ...
