Apache HttpClient 使用 POST 方法

可以使用下面的代码将需要查询的内容发送到 Apple.com 查找对话框。

String url = "https://selfsolve.apple.com/wcResults.do";

HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost(url);

// add header
post.setHeader("User-Agent", USER_AGENT);

List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
urlParameters.add(new BasicNameValuePair("sn", "C02G8416DRJM"));
urlParameters.add(new BasicNameValuePair("cn", ""));
urlParameters.add(new BasicNameValuePair("locale", ""));
urlParameters.add(new BasicNameValuePair("caller", ""));
urlParameters.add(new BasicNameValuePair("num", "12345"));

post.setEntity(new UrlEncodedFormEntity(urlParameters));

HttpResponse response = client.execute(post);
System.out.println("Response Code : " 
              + response.getStatusLine().getStatusCode());

BufferedReader rd = new BufferedReader(
        new InputStreamReader(response.getEntity().getContent()));

StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {
  result.append(line);
}
