BlackBerry模拟器可以连接到Web服务，但真实的设备不能

我正在开发连接到Web服务的BlackBerry应用程序。BlackBerry模拟器可以连接到Web服务，但真实的设备不能

当我在模拟器上开发时，我使用BlackBerry MDS进行模拟器，一切都很顺利。我的应用程序（在模拟器上运行）可以完美地与我的Web服务连接。请注意，模拟器和Web服务位于不同的PC上。

现在，我的项目完成了。我尝试将我的应用程序部署到真实设备（BB 8520）。当我在设备上使用该应用程序时，发现它无法连接到Web服务。我在互联网上做了一项研究，我相信这一定是由于MDS问题。似乎我必须在我的Web服务所在的计算机上使用MDS进行操作，但我仍然无法找到明显的答案。

任何人都请帮助我...

PS。我的Web服务在IIS上发布，并在Visual Studio 2010中开发。BlackBerry应用程序在Eclipse中开发，并通过ksoap2连接到Web服务。 Web服务驻留的计算机上的防火墙已关闭。使用的连接是WIFI。

您是否检查Device中的连接..？如果可以的话。首先检查设备的默认浏览器，以提供诸如“http://www.google.com”之类的内容。如果浏览器不工作，那就是你的DEVICE问题。 – alishaik786 2012-01-13 12:24:38

设备连接到WIFI，我可以打开谷歌，Facebook和任何网站。顺便说一句，我想我正在听到一条线索。好像我需要在Web服务URL之后放置参数like; deviceside = false。（但我还没有尝试过。） – NandNand 2012-01-13 14:44:11

您必须使用HTTPConnetion将所有连接参数添加到您的URL中。创建一个自定义类来检查连接参数。使用以下。

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()); 
} 
}

以上级合并后u必须作出一个包名称impl.javame.com.twitterapime.io并添加下面的类。

`package impl.javame.com.twitterapime.io; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import javax.microedition.io.Connector; import com.twitterapime.io.HttpConnection;

public class HttpConnectionImpl implements 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);  
}

现在你必须整合另外两个类

的HttpConnection
HttpResponsein com.twitterapime.io包。

`package com.twitterapime.io; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; public interface 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是的HttpResponse Class`

`包com.twitterapime。IO;

import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.UnsupportedEncodingException;

public final class HttpResponse私有int代码;

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()); 
    } 
}

使用下面马托检查您的引黄参数。此方法会自动检查您的设备连接可用性并根据您的连接添加连接参数。

protected HttpConnection getConnection(String url) throws IOException { 
    url += HttpConnectionImpl.getConnectionParams(); 
    // 
    return (HttpConnection)Connector.open(url); 
}

以上HttpConnection方法的返回URL与引黄参数..比ü可以使用这个引黄在YOUT InputStream，打开任何URL以及web服务。

我希望这会帮助你...

如果您的设备使用WiFi concat ";interface=wifi" Sring到URL。

谢谢大家。我设法通过在URL中添加interface = wifi; deviceside = false来解决此问题。：D
