可以使用SharedPreferences或者SQLite来保存用户信息
private static HashMap CookieContiner=newHashMap() ;
public voidSaveCookies(HttpResponse httpResponse)
{
Header[] headers =httpResponse.getHeaders("Set-Cookie");
Stringheaderstr=headers.toString();
if (headers == null)
return;
for(int i=0;i
{
String cookie=headers[i].getValue();
String[]cookievalues=cookie.split(";");
for(int j=0;j
{
String[]keyPair=cookievalues[j].split("=");
String key=keyPair[0].trim();
Stringvalue=keyPair.length>1?keyPair[1].trim():"";
CookieContiner.put(key, value);
}
}
}
public voidAddCookies(HttpPost request)
{
StringBuilder sb = new StringBuilder();
Iterator iter =CookieContiner.entrySet().iterator();
while (iter.hasNext()) {
Map.Entry entry = (Map.Entry)iter.next();
String key =entry.getKey().toString();
String val =entry.getValue().toString();
sb.append(key);
sb.append("=");
sb.append(val);
sb.append(";");
}
request.addHeader("cookie",sb.toString());
}
做了一个android网络应用,要求用自己实现的webview去访问web网站,并且在远程登录成功之后把cookie写入到手机,保留用作以后的自动登录。找了好多资料。发觉读取cookies倒还用的很普遍,可是通过程序写cookie却没有太多资料。
先来看一下如何读取cookie吧:
try
{
DefaultHttpClient httpclient= new DefaultHttpClient();
HttpGet httpget = newHttpGet("http://www.hlovey.com/");
HttpResponse response =httpclient.execute(httpget);
HttpEntity entity =response.getEntity();
List<Cookie> cookies =httpclient.getCookieStore().getCookies();
if (entity != null) {
entity.consumeContent();
}
if (cookies.isEmpty()){
Log.i(TAG,"NONE");
} else {
for (int i = 0; i <cookies.size(); i++) {
Log.i(TAG,"- domain " +cookies.get(i).getDomain());
Log.i(TAG,"- path " +cookies.get(i).getPath());
Log.i(TAG,"- value " +cookies.get(i).getValue());
Log.i(TAG,"- name " +cookies.get(i).getName());
Log.i(TAG,"- port " +cookies.get(i).getPorts());
Log.i(TAG,"- comment " +cookies.get(i).getComment());
Log.i(TAG,"- commenturl" +cookies.get(i).getCommentURL());
Log.i(TAG,"- all " +cookies.get(i).toString());
}
}
httpclient.getConnectionManager().shutdown();
}catch(Exception e){
//Todo
}finally{
//Todo
}
通过分析com.android.browser的源码,发现android默认的browser增加cookie是在数据库中增加记录,和window不同,win是采用一个txt文本文件的形式来存储cookie。而android是将cookie存储在数据库中。具体的介绍在《androidcookie存储位置》一文中有介绍。我们都知道,android每个应用程序的存储空间都是独立的。不管使用preference还是database存储,都会在每个/data/data/packagename/下面进行存储(preference存储在/data/data/packagename/shared_prefs/xxxx.xml)。前面也说到cookie是存在数据库中,那么如果采用非浏览器访问网络需要保留cookie的话我们就应该在database中建立cookies表,并且存入相应的cookies数据。仿照默认broswer的代码:
private static SQLiteDatabase mDatabase =null;
private static final String DATABASE_FILE ="webview.db";
private static final StringCOOKIES_NAME_COL = "name";
private static final StringCOOKIES_VALUE_COL = "value";
private static final StringCOOKIES_DOMAIN_COL = "domain";
private static final StringCOOKIES_PATH_COL = "path";
private static final StringCOOKIES_EXPIRES_COL = "expires";
private static final StringCOOKIES_SECURE_COL = "secure";
mDatabase =LoginApiActivity.this.openOrCreateDatabase(DATABASE_FILE, 0,null);
//创建cookie数据库
if (mDatabase != null){
//cookies
mDatabase.execSQL("CREATE TABLE IF NOT EXISTS cookies "
+ " (_id INTEGER PRIMARY KEY, "
+ COOKIES_NAME_COL + " TEXT, " +COOKIES_VALUE_COL
+ " TEXT, " + COOKIES_DOMAIN_COL + " TEXT,"
+ COOKIES_PATH_COL + " TEXT, " +COOKIES_EXPIRES_COL
+ " INTEGER, " + COOKIES_SECURE_COL + " INTEGER"+ ");");
mDatabase.execSQL("CREATE INDEX IF NOT EXISTS cookiesIndex ON"
+ "cookies" + " (path)");
}
}
public void addCookie(Cookie cookie){
if (cookie.getDomain()== null || cookie.getPath() == null || cookie.getName() ==null
||mDatabase == null) {
return;
}
String mCookieLock ="asd";
synchronized(mCookieLock) {
ContentValues cookieVal = newContentValues();
cookieVal.put(COOKIES_DOMAIN_COL,cookie.getDomain());
cookieVal.put(COOKIES_PATH_COL,cookie.getPath());
cookieVal.put(COOKIES_NAME_COL,cookie.getName());
cookieVal.put(COOKIES_VALUE_COL,cookie.getValue());
mDatabase.insert("cookies", null,cookieVal);
}
}
