本篇文章給大家分享的是有關(guān)java使用post方式如何實(shí)現(xiàn)訪問后臺(tái)服務(wù)器，小編覺得挺實(shí)用的，因此分享給大家學(xué)習(xí)，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

首先，上代碼：
重慶分公司
重慶分公司
Runnable payRunnable = new Runnable()
{
@Override
public void run()
{
try
{
HashMap payParamMap = new HashMap();
payParamMap.put("canshu" ,"woshicanshu" );
String payParamStr = XmlUtils.toXml(payParamMap);//轉(zhuǎn)換成xml格式
String resultStr = Utils.httpPost(UrlString, payParamStr);//調(diào)用訪問函數(shù)
//resultStr 就是訪問所得到的返回值
}
catch(Exception e)
{
e.printStackTrace();
}
}
};
// 必須異步調(diào)用
Thread payThread = new Thread(payRunnable);
payThread.start(); 其次，上代碼：
public class Utils {
private static final String TAG = "woshiTag";
public static String httpPost(String url, String entity) {
if (url == null || url.length() == 0) {
Log.e(TAG, "httpPost, url is null");
return null;
}
HttpClient httpClient = getNewHttpClient();
HttpPost httpPost = new HttpPost(url);
try {
httpPost.setEntity(new StringEntity(entity, HTTP.UTF_8));
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
HttpResponse resp = httpClient.execute(httpPost);
if (resp.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e(TAG, "httpGet fail, status code = " + resp.getStatusLine().getStatusCode());
return null;
}
return new String(EntityUtils.toByteArray(resp.getEntity()));
} catch (Exception e) {
Log.e(TAG, "httpPost exception, e = " + e.getMessage());
e.printStackTrace();
return null;
}
}
private static HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
}以上就是java使用post方式如何實(shí)現(xiàn)訪問后臺(tái)服務(wù)器，小編相信有部分知識(shí)點(diǎn)可能是我們?nèi)粘９ぷ鲿?huì)見到或用到的。希望你能通過這篇文章學(xué)到更多知識(shí)。更多詳情敬請(qǐng)關(guān)注創(chuàng)新互聯(lián)行業(yè)資訊頻道。
