android WebView 与 HttpClient Cookie
转载自:http://blog.sina.com.cn/s/blog_694448320101gftv.html
我的测试案例：
public class MainActivity extends ActionBarActivity {
Button btnCookie;
WebView webView;
String url;
TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(MainActivity.this);
cookieSyncManager.sync();
btnCookie=(Button)findViewById(R.id.btnCookie);
webView=(WebView)findViewById(R.id.webView);
textView=(TextView)findViewById(R.id.textView);
url="https://login.taobao.com/";
webView.loadUrl(url);
btnCookie.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
CookieSyncManager.getInstance().sync();
CookieManager cookieManager = CookieManager.getInstance();
String cookieStr = cookieManager.getCookie(url);
textView.setText("cookie:"+cookieStr);
}
});
}
}
1.WebView中的Cookie信息，或者WebView访问某网络地址前设置其Cookie
CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(MainActivity.this);
cookieSyncManager.sync();
CookieManager cookieManager = CookieManager.getInstance();
System.out.println(cookieManager.getCookie("http://xxx.xxx.xxx"));
在webView加载完成某网页之后，可以同步cookie，从而得到想要的Cookie（得到的Cookie可以传入HttpClient中,也可以同步给其它的webview）
CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(MainActivity.this);
cookieSyncManager.sync();
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setCookie("http://weibo.com", "session_id=\"xxx==|xxxx|xxx\"");
CookieSyncManager.getInstance().sync();
WebViewSubView webViewSubView = newWebViewSubView();
myWebView= (WebView)findViewById(R.id.webview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(webViewSubView);
myWebView.loadUrl("http://xxx.xxx.xxx");
在WebView加载页面之前，可以选同步Cookie，然后再加载网页。
2.HttpClient访问某网络地址时，设置Cookie.
getMethod.setHeader("Cookie", "session_id=\"xxx==|xxxxx|xxxx\"");当然，也可以在PostMethod中设置
protected
void
onCreate(Bundle savedInstanceState) {
super
.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView)findViewById(R.id.showhtml);
webView = (WebView)findViewById(R.id.showhtmlinwebview);
String baseUrl =
"http://xxxx.xxx.com"
;
HttpGet getMethod =
new
HttpGet(baseUrl);
getMethod.setHeader("Cookie", "session_id=\"xxx==|xxxxx|xxxx\"");
HttpClient httpClient =
new
DefaultHttpClient();
try
{
HttpResponse response = httpClient.execute(getMethod);
//发起GET请求
Log.i(TAG,
"resCode = "
+ response.getStatusLine().getStatusCode());
//获取响应码
String htmlResponse = EntityUtils.toString(response.getEntity(),
"utf-8"
);
System.out.println(htmlResponse);
webView.getSettings().setJavaScriptEnabled(
true
);
webView.loadData(htmlResponse,
"text/html"
,
"utf-8"
);
}
catch
(ClientProtocolException e) {
e.printStackTrace();
}
catch
(IOException e) {
e.printStackTrace();
}
}
