用法。。。

	private HttpPost getHttpPost(String url) {

				"application/x-www-form-urlencoded; charset=UTF-8");

		try {
			postMethod.setEntity(new UrlEncodedFormEntity(setMethodParamList(
					pKey, pValue), "UTF-8"));

		}

        HttpConnectionParams.setSoTimeout(httpParams, TheStoreHttpClient.SET_SOCKET_TIMEOUT);
		
		return postMethod;
	}

public HttpResponse getHttpResponse(String pKey, String pValve) {
		
		HttpPost postMethod = getHttpPost(pKey, pValve);
        HttpClient client  = new CustHttpClient();
        //client.getParams().setParameter(
						ConnRouteParams.DEFAULT_PROXY, new HttpHost("http://xx.xx.xx.xx", 80))
        HttpResponse httpResponse = null;
		try {
			httpResponse = client.execute(postMethod);
			if (httpResponse.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
				//当http状态不是200时终止执行??
				postMethod.abort();
			}
		} catch (ClientProtocolException e) {
			postMethod.abort();
			client.getConnectionManager().shutdown();
		} catch (java.net.SocketTimeoutException e) {
			postMethod.abort();
			client.getConnectionManager().shutdown();
		} catch (IOException e) {
			postMethod.abort();

		} 
		return httpResponse;
	}


httpclient 存在转发时获取新的地址
    public static String getJoinUri(String uri) {
        String joinUri = null;
    	if (uri == null || "".equals(uri)){
    		Log.w(UpgradeApplication.TAG,"getJoinuri is null or empty");
    		return joinUri;
    	}
        HttpClient httpClient = new DefaultHttpClient();
        HttpGet request = new HttpGet(uri);
        setProxy(request, httpClient);
        HttpResponse response = null;
        request.getParams().setIntParameter(HttpConnectionParams.SO_TIMEOUT,
        		UpgradeApplication.config.getSo_timeout());
        request.getParams().setIntParameter(HttpConnectionParams.CONNECTION_TIMEOUT,
        		UpgradeApplication.config.getConnection_timeout());
        request.getParams().setBooleanParameter(ClientPNames.HANDLE_REDIRECTS, false);
        try {
            response = httpClient.execute(request);
            int statusCode = response.getStatusLine().getStatusCode();
            if (!isRedirectRequested(statusCode)) {
                return null;
            }
            String locationHeader = response.getFirstHeader("Location").getValue();
            URI mUri = URI.create(locationHeader);
            if (!mUri.isAbsolute()) {
                try {
                    URI requestURI = new URI(request.getRequestLine().getUri());
                    mUri = URIUtils.resolve(requestURI, locationHeader);
                } catch (URISyntaxException e) {
                    e.printStackTrace();
                }
            }
            joinUri = mUri.toString();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();

			if (httpClient != null
					&& httpClient.getConnectionManager() != null) {
				httpClient.getConnectionManager().shutdown();

			}
		}
        return joinUri;
    }


AndroidHttpClient 下载时获取文件大小
 public static long getSize(String zipurl,Context context) {
    	if (zipurl == null || "".equals(zipurl)){
    		Log.w(UpgradeApplication.TAG,"getJoinuri is null or empty");
    		return 0l;
    	}
    	AndroidHttpClient client = AndroidHttpClient.newInstance("AndroidDownloadManager", context);
		HttpResponse response = null;
		Header header = null;
		HttpGet request = new HttpGet(zipurl);
		HttpParams httpParameters = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParameters,
        			5 * 1000);
        HttpConnectionParams.setSoTimeout(httpParameters, 5 * 1000);
		request.setParams(httpParameters);
		try{
			response = client.execute(request);
			header = response.getFirstHeader("Content-Length");
		} catch (IllegalArgumentException ex) {
			Log.e(UpgradeApplication.TAG, "IllegalArgumentException", ex);
			header = null;
			request.abort();
    	} catch (java.net.SocketException se) {
    		Log.e(UpgradeApplication.TAG, "IOException", se);
			header = null;
			request.abort();
		}  catch (java.io.IOException ioe) {
    		Log.e(UpgradeApplication.TAG, "IOException", ioe);
			header = null;
			request.abort();
		} finally {
			if (client != null) {
                client.close();
                client = null;
            }
		} 
		String headerContentLength = null;
		if (header != null) {
                headerContentLength = header.getValue();
        }
		long length = headerContentLength != null ? Long.parseLong(headerContentLength):-1L;
		return length;

用httpclinet4.0模拟登录新浪微博,抓包后分析上传参数,密码加密了,我将加密的密文和各种参数上传登录不了(获得不了cookie),后来我用了其他的方法,就是登录新浪会员(密码是明文),然后跳转到微博,成功过,但现在不行了,跳转cookie被拒绝,求大神指教啊,我纠结了很久
