httpclient post请求例子(无参数名与带参数名的例子)

    HttpClient httpClient = new DefaultHttpClient(); 
    HttpPost httpPost = new HttpPost(url);
//  httpPost.setHeader("Accept-Encoding", "gzip,deflate");//表示返回的数据是压缩的zip格式
    String postParam = "";//请求的参数内容          
    List<NameValuePair> nvps = new ArrayList<NameValuePair>();  
    nvps.add(new BasicNameValuePair("data", postParam));  
    httpPost.setEntity(new UrlEncodedFormEntity(nvps,"utf-8")); 
    HttpResponse response = httpClient.execute(httpPost);    
    HttpEntity entity = response.getEntity();
    if (response.getStatusLine().getStatusCode() == 200) {if (entity.getContentEncoding().toString().equalsIgnoreCase("Content-Encoding: gzip")) {
                response.setEntity(new GzipDecompressingEntity(response.getEntity())); //对zip进行解压
                entity = response.getEntity();
           }
           String responseContent = EntityUtils.toString(entity);
           System.out.println("responseContent: \n" + responseContent); 
   }
}

　　 HttpClient httpClient = new DefaultHttpClient(); 
    HttpPost httpPost = new HttpPost(url);
//  httpPost.setHeader("Accept-Encoding", "gzip,deflate");//表示返回的数据是压缩的zip格式
    String postParam = "";//请求的参数内容 
    StringEntity paramEntity = new StringEntity(postParam);//无参数名，只是参数内容
    httpPost.setEntity(paramEntity); 
    HttpResponse response = httpClient.execute(httpPost);    
    HttpEntity entity = response.getEntity();
    if (response.getStatusLine().getStatusCode() == 200) {if (entity.getContentEncoding().toString().equalsIgnoreCase("Content-Encoding: gzip")) {
                response.setEntity(new GzipDecompressingEntity(response.getEntity())); //对zip进行解压
                entity = response.getEntity();
           }
           String responseContent = EntityUtils.toString(entity);
           System.out.println("responseContent: \n" + responseContent); 
   }
