由于微信API接口建议使用Https请求方式而且过不久就废弃http请求方式了所以提供以下Https工具类

public class SSLClient extends DefaultHttpClient{    public SSLClient() throws Exception{        super();        SSLContext ctx = SSLContext.getInstance("TLS");        X509TrustManager tm = new X509TrustManager() {            @Override            public void checkClientTrusted(X509Certificate[] chain,                                           String authType) throws CertificateException {            }            @Override            public void checkServerTrusted(X509Certificate[] chain,                                           String authType) throws CertificateException {            }            @Override            public X509Certificate[] getAcceptedIssuers() {                return null;            }        };        ctx.init(null, new TrustManager[]{tm}, null);        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);        ClientConnectionManager ccm = this.getConnectionManager();        SchemeRegistry sr = ccm.getSchemeRegistry();        sr.register(new Scheme("https", 443, ssf));    }}

https请求工具类

public class HttpClientUtil {    /**     * 发送post请求     * @param url     * @param map     * @param charset     * @return     */    public static String doPost(String url,Map<String,String> map,String charset){        HttpClient httpClient = null;        HttpPost httpPost = null;        String result = null;        try{            httpClient = new SSLClient();            httpPost = new HttpPost(url);            //设置参数            List<NameValuePair> list = new ArrayList<NameValuePair>();            Iterator iterator = map.entrySet().iterator();            while(iterator.hasNext()){                Entry<String,String> elem = (Entry<String, String>) iterator.next();                list.add(new BasicNameValuePair(elem.getKey(),elem.getValue()));            }            if(list.size() > 0){                UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list,charset);                httpPost.setEntity(entity);            }            HttpResponse response = httpClient.execute(httpPost);            if(response != null){                HttpEntity resEntity = response.getEntity();                if(resEntity != null){                    result = EntityUtils.toString(resEntity,charset);                }            }        }catch(Exception ex){            ex.printStackTrace();        }        return result;    }    /**     * 发送get请求     * @param url       链接地址     * @param charset   字符编码，若为null则默认utf-8     * @return     */    public static String doGet(String url,String charset){        if(null == charset){            charset = "utf-8";        }        HttpClient httpClient = null;        HttpGet httpGet= null;        String result = null;        try {            httpClient = new SSLClient();            httpGet = new HttpGet(url);            HttpResponse response = httpClient.execute(httpGet);            if(response != null){                HttpEntity resEntity = response.getEntity();                if(resEntity != null){                    result = EntityUtils.toString(resEntity,charset);                }            }        } catch (Exception e) {            e.printStackTrace();        }        return result;    }}

本工具类根据http://blog.csdn.net/rongyongfeikai2/article/details/41659353/进行了小改
