如何使用Apache HttpClient 4.5在big5中发送post请求和get响应

Question

它使用Apache HttpClient 4.5在big5中发送post请求编码。Java代码如下所示，结果显示了不可读的代码，如？请给出一些修复它的建议。

   hpr803.getResps1("http://web-reg-server.803.org.tw/TRE/stepB1.asp");

  //the method to send post request and get response
  public void getResps1(String param) throws IOException{    
    ArrayList<NameValuePair> pairList = new ArrayList<NameValuePair>();

    // Post request example hospital 803
   pairList.add(new BasicNameValuePair("syear", "104"));
   pairList.add(new BasicNameValuePair("smonth", "7"));
   pairList.add(new BasicNameValuePair("sday", "20"));
   pairList.add(new BasicNameValuePair("eyear", "104"));
   pairList.add(new BasicNameValuePair("emonth", "8"));
   pairList.add(new BasicNameValuePair("eday", "5"));
   pairList.add(new BasicNameValuePair("HospNO", "1"));
   pairList.add(new BasicNameValuePair("SectNO", ""));
   pairList.add(new BasicNameValuePair("EmpNO", ""));

     HttpPost httpPost = new HttpPost(param);
     //big5 code
     StringEntity entity = new StringEntity(URLEncodedUtils.format(pairList, "big5"));
    httpPost.setEntity(entity);

    //httpPost.setEntity(new UrlEncodedFormEntity(pairList, "big5"));
    CloseableHttpClient demo = HttpClients.createDefault();
    HttpGet httpGet = new HttpGet(param);
    HttpResponse response = demo.execute(httpGet);
    String responseString = EntityUtils.toString(response.getEntity(), "big5");
    response = demo.execute(httpPost);
    responseString = EntityUtils.toString(response.getEntity());
    if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
        System.out.println("responseString   big5 ~~~~~~~~~~     " +responseString);
    } else {
        System.out.println("response.getStatusLine   ``````````````````````  " +response.getStatusLine());
    }
}

问题不在您的代码中。我试过了，它工作得很好。它在您的控制台/ Eclipse / IntelliJIdea中，这取决于您从哪里启动它。我修改了你的代码，把它写到一个文件中：

String responseString = EntityUtils.toString(response.getEntity(), "big5");
    response = demo.execute(httpPost);
    //responseString = EntityUtils.toString(response.getEntity());
    if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
        FileOutputStream fos = new FileOutputStream("C:\\test\\Big5Test.html");
        response.getEntity().writeTo(fos);
        fos.close();
    } else {
        System.out.println("response.getStatusLine   ``````````````````````  " +response.getStatusLine());
    }

当我在Firefox中打开这个文件时，一切都很好。请在您的系统上试用。
