Java中HttpPost請求流程--4.5.2版本

public class HttpTest(){
    public void testHttpPost() throws Exception{
        //1. 創建一個客戶端(瀏覽器)
        HttpClient httpClient = HttpClientBuilder.create().build();
        //2. 初始化post請求的過程
        String url = "www.baidu.com"
        HttpPost post = new HttpPost("url");
        //3.傳遞參數
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();  
        nvps.add(new BasicNameValuePair("arg0", "1"));  
        nvps.add(new BasicNameValuePair("arg1", "2"));  
        post.setEntity(new UrlEncodedFormEntity(nvps)); 
        post.setHeader("Content-Type", "application/x-www-form-urlencoded");

        //4. 用剛纔創建的客戶端去執行post請求
        //webservice SOAP
        HttpResponse response = httpClient.execute(post);
        HttpEntity httpEntity = response.getEntity();
        String result = EntityUtils.toString(httpEntity, "UTF-8");
        //JSONObject jsonObject = JSONObject.fromObject(result);
        System.out.println(result);
        }
    }
