后台調用后台接口並獲取返回值：
//-----開始------------
DefaultHttpClient httpClient = new DefaultHttpClient();
String url="http://192.xxx.x.xxx:xxxx/xx/xx";
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
// ----傳參----
nvps.add(new BasicNameValuePair("VId",“xxx”));
nvps.add(new BasicNameValuePair("password",“xxx”));
nvps.add(new BasicNameValuePair("telephone", “xxx”));
nvps.add(new BasicNameValuePair("nickName",“xxx”));
try {
httpPost.setEntity(new UrlEncodedFormEntity(nvps, "utf-8"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
System.out.println("0000");
// 執行請求
HttpResponse response = null;
try {
response = httpClient.execute(httpPost);
} catch (IOException e) {
System.out.println("0002");
e.printStackTrace();
}
System.out.println("0003");
BufferedReader in = null;
String content = null;
try {
System.out.println("0004");
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
content = sb.toString();
} catch (UnsupportedOperationException | IOException e) {
e.printStackTrace();
} finally {
try {
if(in != null) {
in.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
// 打印返回值
System.out.println(content);
//------結束--------
