给你分享一个我的android访问http的类，超级好用，从来没让我担心过

 public class MyHttpClient {
    /** 
     * 通过HttpClient发送GET请求 
     * @param path 请求路径 
     * @param params 请求参数 
     * @param ecoding 请求编码 
     * @return 请求是否成功 
     */  
    public HttpResponse sendHttpClientGETRequest(String path,Map<String, String> params, String ecoding) throws Exception {  
        StringBuilder url=new StringBuilder(path);  
        url.append("?");  
        for (Map.Entry<String, String> entry : params.entrySet()) {  
            url.append(entry.getKey()).append("=");  
            url.append(URLEncoder.encode(entry.getValue(),ecoding));  
            url.append("&");  
        }  
        url.deleteCharAt(url.length()-1);  
        HttpGet httpGet=new HttpGet(url.toString());  
        DefaultHttpClient client=new DefaultHttpClient();  
        client.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);
        client.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 10000);
        HttpResponse response=client.execute(httpGet); 
        if(response.getStatusLine().getStatusCode()==200){  
            return response;  
        }  
        return null;  
    }

    public HttpResponse sendHttpClientPOSTRequest(String path,  
           Map<String, String> params, String ecoding) throws Exception {  
       List<NameValuePair> pair=new ArrayList<NameValuePair>();//存放请求参数  
       if(params!=null && !params.isEmpty()){  
           for (Map.Entry<String, String> entry : params.entrySet()) {

           return response;

       return null;
