android webview模拟网页post操作

//Sample.java

import org.apache.http.util.EncodingUtils;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class WebLogin extends Activity {
private WebView mWebView;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView)findViewById(R.id.web_view);
String URL = "https://reg.163.com/logins.jsp?type=1&product=mail126&url=http://entry.mail.126.com/cgi/ntesdoor?hid%3D10010102%26lightweight%3D1%26verifycookie%3D1%26language%3D-1%26style%3D-1";
String postData = "domain=126.com&language=-1&bCookie=&username=username%40126.com&savelogin=&url2=http%3A%2F%2Fmail.126.com%2Ferrorpage%2Ferr_126.htm&user=username&password=password&style=-1&secure=&enter.x=%B5%C7%A1%A1%C2%BC";
mWebView.postUrl(URL, EncodingUtils.getBytes(postData, "BASE64"));
}
}

先用firebug查看网页post的网址，用变量URL存储，然后查看post的参数，将其复制，用postData存储，

然后调用 webview的postUrl方法，第一个参数为url，第二个参数为数据，

这里要注意的是，第二个参数是byte[]型的，所以我们要把我们得到的String型的postData作点转换处理，

用EncodingUtils.getBytes(postData, "BASE64")，转换成byte[]就行了
