論壇里有幾個人發(fā)了一些代碼，如何獲得UA，但是自己都實(shí)踐過了一遍，一個都不行。最近做OPHONE的項(xiàng)目，跟移動終端的人打了不少交道，了解了一些相關(guān)知識，這里把權(quán)威的解決方案發(fā)布出來。 我不是方法的發(fā)明者，但是我是方法的實(shí)踐者。順便也在這里感謝相關(guān)的人。
原理：
OPHONE的UA存放位置：
1）OPHONE 1.0和1.5 存放于/opl/etc/properties.xml
1）OPHONE 2.0 存放于/opl/etc/product_properties.xml
大家可以通過下面的步驟自己查看：
1），連上手機(jī)，或者模擬器。
2），輸入
adb shell
3），輸入 cd opl
4），輸入 cd etc
5），輸入 cat properties.xml (或者cat product_properties.xml 【OPHONE2.0】)
結(jié)果如下圖：
以上就是properties.xml的內(nèi)容，接下來就是獲得這個UA，加到自己的聯(lián)網(wǎng)請求里去。
我自己寫了一個，適用于目前3個版本的OPHONE。
AndroidPlatform.java
package com.***.****;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
public class AndroidPlatform {
public static final String KEYSTRING_USER_AGENT = "user_agent_key";
public static String getUAFromProperties()
{
try {
FileInputStream is = getPropertyStream();
ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream();
byte buf[] = new byte[1024];
for(int k = 0; -1 != (k = is.read(buf));)
bytearrayoutputstream.write(buf, 0, k);
String fileString = new String(bytearrayoutputstream.toByteArray(), "UTF-8");
return getProperties(KEYSTRING_USER_AGENT, fileString);
//System.out.println("IS FILE Android Platform " + bytearrayoutputstream.size() + " "+());
} catch (Exception e) {
// TODO: handle exception
System.out.println("IS FILE erororo");
e.printStackTrace();
}
return null;
}
public static FileInputStream getPropertyStream()
{
try {
File property = new java.io.File("/opl/etc/properties.xml");
if(property.exists())
{
return new FileInputStream(new java.io.File("/opl/etc/properties.xml"));
}
else
{
property = new java.io.File("/opl/etc/product_properties.xml");
if(property.exists())
{
return new FileInputStream(new java.io.File("/opl/etc/product_properties.xml"));
}
else
{
return null;
}
}
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return null;
}
public static String getProperties(String key, String content)
{
String STARTKEY = "<"+key+">";
String ENDKEY = "</"+key+">";
content = content.replace("\r", "");
content = content.replace("\n", "");
int startIndex = content.indexOf(STARTKEY) + STARTKEY.length();
int endIndex = content.indexOf(ENDKEY);
if(startIndex > -1 && endIndex > -1)
{
return content.substring(startIndex, endIndex);
}
else
return null;
}
}
聯(lián)網(wǎng)請求時，加入UA即可，這樣就做到了自動適配了。具體如下：
private int CountMoneyCMWAPNEWWAY(String urlstr)
{
String strHead = "";
try{
if(!GameLet._self.isNetworkCMWAPAvailable())
{
GameLet._self.ActiveNetWorkByMode("wap");
Thread.sleep(5000);
}
int splashIndex = urlstr.indexOf("/", 7);
String hosturl = urlstr.substring(7, splashIndex);
String hostfile = urlstr.substring(splashIndex);
HttpHost proxy = new HttpHost( "10.0.0.172", 80, "http");
HttpHost target = new HttpHost(hosturl, 80, "http");
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 20 * 1000);
HttpConnectionParams.setSoTimeout(httpParams, 20 * 1000);
HttpConnectionParams.setSocketBufferSize(httpParams, 8192);
HttpClientParams.setRedirecting(httpParams, true);
String userAgent =
AndroidPlatform.getUAFromProperties();
HttpProtocolParams.setUserAgent(httpParams, userAgent);
DefaultHttpClient httpclient = new DefaultHttpClient(httpParams);
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
HttpGet req = new HttpGet(hostfile);
HttpResponse rsp = httpclient.execute(target, req);
HttpEntity entity = rsp.getEntity();
InputStream inputstream = entity.getContent();
ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream();
byte abyte1[] = new byte[1024];
for(int k = 0; -1 != (k = inputstream.read(abyte1));)
bytearrayoutputstream.write(abyte1, 0, k);
strHead = new String(bytearrayoutputstream.toByteArray(), "UTF-8");
httpclient.getConnectionManager().shutdown();
}
catch (Exception e) {
return 2;
}
if(strHead.indexOf("status=1301") > -1 || strHead.indexOf("status=1300") > -1)
{
return 1;
}
else
{
return 0;
}
}
