用httpclient模拟浏览器，登录新浪微博

Ying-er — Wed, 11 Jul 2012 03:59:00 GMT

①用Fiddler2追踪登录时的post请求，发现需要以下参数：

check

uname

backURL

autoLogin

pwd

其中，backURL="/"，check=“1”，autoLogin可默认为1

于是，只剩 uname和 pwd

②创建一个HttpClient

private DefaultHttpClient httpclient = new DefaultHttpClient();

③创建一个 HttpPost

HttpPost httpost = new HttpPost(CommonConst.loginUrl);

④伪装httpost，骗过服务器

    /**
     * pretend to be a browser quietly
     */
    private void setPostHeader(HttpPost post) {
        post.setHeader(CommonConst.UserAgent, CommonConst.HttpAgent);
        post.setHeader("Origin", CommonConst.weiboUrl);
        post.setHeader("Cache-Control", "max-age=0");
        post.setHeader("Accept",
                "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
        post.setHeader("Accept-Encoding", "gzip,deflate,sdch");
        post.setHeader("Accept-Language", "en-US,en;q=0.8");
        post.setHeader("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3");
        post.setHeader("Accept-Encoding", "gzip,deflate,sdch");
        post.setHeader("Referer", CommonConst.loginUrl);
    }

⑤创建NameValuePair

List<BasicNameValuePair> nvps = new ArrayList<BasicNameValuePair>();
        nvps.add(new BasicNameValuePair("check", this.check));
        nvps.add(new BasicNameValuePair("uname", this.uname));
        nvps.add(new BasicNameValuePair("backURL", this.backURL));
        nvps.add(new BasicNameValuePair("autoLogin", this.autoLogin));
        nvps.add(new BasicNameValuePair("pwd", this.pwd));

⑥用setEntity方法，给httpost设置相关参数

httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

⑦向相应的host上提交post请求

HttpHost targetHost = new HttpHost(CommonConst.host);
response = httpclient.execute(targetHost, httpost);

login代码：

private boolean login() {
        // httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,proxy);
        HttpPost httpost = new HttpPost(CommonConst.loginUrl);
        setPostHeader(httpost);
        // All the parameters post to the web site
        List<BasicNameValuePair> nvps = new ArrayList<BasicNameValuePair>();
        nvps.add(new BasicNameValuePair("check", this.check));
        nvps.add(new BasicNameValuePair("uname", this.uname));
        nvps.add(new BasicNameValuePair("backURL", this.backURL));
        nvps.add(new BasicNameValuePair("autoLogin", this.autoLogin));
        nvps.add(new BasicNameValuePair("pwd", this.pwd));

        try {
            httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
            HttpHost targetHost = new HttpHost(CommonConst.host);
            response = httpclient.execute(targetHost, httpost);
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        } finally {
            httpost.abort();
        }
        return true;
    }

附CommonConst.java

package com.yinger;

public class CommonConst {
    public static String HttpAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.46 Safari/536.5";
    public static String loginUrl = "http://m.weibo.cn/login";
    public static String host = "m.weibo.cn";
    public static String weiboUrl = "http://m.weibo.cn";
    public static String UserAgent = "User-Agent";
}

#Android 使用User Location获取当前经纬度

Ying-er — Sun, 25 Sep 2011 13:28:00 GMT

step1：声明权限

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

step2：获取LocationManager对象

LocationManager locationManager = (LocationManager)LocationTest.this.getSystemService(Context.LOCATION_SERVICE);

step3：选择LocationProvider，绑定LocationListener对象

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new MyLocationListener());

附：MyLocationListener

    private class MyLocationListener implements LocationListener{

        @Override
        public void onLocationChanged(Location location) {
            // TODO Auto-generated method stub
            System.out.println(location.getLatitude());
            System.out.println(location.getLongitude());
        }

        @Override
        public void onProviderDisabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProviderEnabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
            // TODO Auto-generated method stub

        }

    }
