如何在Webview请求网站时使用Session
01
//webview初始化的时候调用
02
main_view= (WebView) findViewById(R.id.main_webview);
03
new
WebViewTask().execute();
04
 
05
private
class
WebViewTask 
extends
AsyncTask<Void,Void, Boolean> {
06
StringsessionCookie;
07
CookieManagercookieManager;
08
09
@Override
10
protected
void
onPreExecute() {
11
CookieSyncManager.createInstance(MainActivity.
this
);
12
cookieManager= CookieManager.getInstance();
13
14
sessionCookie= 
new
PersistentConfig(getApplicationContext())
15
.getCookieString();
16
if
(sessionCookie!= 
null
){
17
//delete old cookies
18
cookieManager.removeSessionCookie();
19
}
20
super
.onPreExecute();
21
}
22
23
protected
BooleandoInBackground(Void... param) {
24
//this is very important - THIS IS THE HACK
25
SystemClock.sleep(
1000
);
26
return
false
;
27
}
28
29
@Override
30
protected
void
onPostExecute(Boolean result) {
31
if
(sessionCookie!= 
null
){
32
cookieManager.setCookie(Constants.ServerUrl.WEB_URL,
33
sessionCookie);
34
CookieSyncManager.getInstance().sync();
35
}
36
main_view.setScrollbarFadingEnabled(
true
);
37
main_view.getSettings().setPluginsEnabled(
true
);
38
main_view.getSettings().setPluginState(PluginState.ON);
39
main_view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
40
WebSettingswebSettings = main_view.getSettings();
41
webSettings.setJavaScriptEnabled(
true
);
42
//设置可以访问文件
43
webSettings.setAllowFileAccess(
true
);
44
//设置支持缩放
45
webSettings.setBuiltInZoomControls(
true
);
46
main_view.setWebViewClient(
new
WebViewClient(){
47
@Override
48
public
void
onPageStarted(WebView view, String url,
49
Bitmapfavicon) {
50
//TODO Auto-generated method stub 
51
super
.onPageStarted(view,url, favicon);
52
}
53
54
@Override
55
public
void
onLoadResource(WebView view, String url) {
56
//history(); 
57
}
58
});
59
main_view.setWebChromeClient(
new
WebChromeClient(){
60
public
void
onProgressChanged(WebView view, 
int
progress){
61
//Change
62
}
63
});
64
ShowUrlView(Constants.ServerUrl.INDEX);
65
}
66
}
这样就可以每次刷新页面的时候带着session一起请求如果想保存用户信息，还是老方法SharedPreferences
