Android连接服务器的方法
1.使用url连接
public class MyURLActivityextends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread thread =new Thread(new Runnable() {
@Override
public void run() {
URL url;
String temp;
StringBuffer sb =new StringBuffer();
try {
url =new URL("http://192.168.18.157?name=allen");// 根据自己的服务器地址填写
BufferedReader in =new BufferedReader(new InputStreamReader(url.openStream()));// 获取输入流
while ((temp = in.readLine()) !=null) {
sb.append(temp);
}
System.out.println(sb.toString());
in.close();
}catch (MalformedURLException me) {
System.err.println("你输入的URL格式有问题！");
me.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
}
}
2.使用httpclient
public class MyHttpClientActivityextends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread thread =new Thread(new Runnable() {
@Override
public void run() {
HttpClient client =new DefaultHttpClient();
HttpGet httpGet =new HttpGet("http://192.168.18.157?name=allen");// 根据自己的服务器地址填写
try {
HttpResponse response = client.execute(httpGet);
String temp;
StringBuffer sb =new StringBuffer();
BufferedReader in =new BufferedReader(new InputStreamReader(response.getEntity().getContent()));// 获取输入流
while ((temp = in.readLine()) !=null) {
sb.append(temp);
}
System.out.println(sb.toString());
in.close();
}catch (ClientProtocolException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
}
}
3. HttpURLConnection连接
public class MyHttpURLConnectionActivityextends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread thread =new Thread(new Runnable() {
@Override
public void run() {
BufferedReader bufferedReader =null;
try {
URL url =new URL("http://192.168.18.157");// 根据自己的服务器地址填写
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(10000);
conn.setDoOutput(true);// 允许输出
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection","Keep-Alive");
conn.setRequestProperty("Charset","GBK");
OutputStream os = conn.getOutputStream();
os.write("name=allen".getBytes());
if (conn.getResponseCode() ==200) {
System.out.println(conn.toString());
InputStream is = conn.getInputStream();
InputStreamReader isr =new InputStreamReader(is,"GBK");
bufferedReader =new BufferedReader(isr);
}
String result ="";
String line ="";
if (bufferedReader !=null) {
try {
while ((line = bufferedReader.readLine()) !=null) {
result += line;
}
}catch (IOException e) {
e.printStackTrace();
}
}
System.out.println(result);
}catch (MalformedURLException e) {
// URL格式错误
e.printStackTrace();
}catch (UnsupportedEncodingException e) {
// 不支持你设置的编码
e.printStackTrace();
}catch (ProtocolException e) {
// 请求方式不支持
e.printStackTrace();
}catch (IOException e) {
// 输入输出通讯出错
e.printStackTrace();
}
}
});
thread.start();
}
}
4. ksoap2连接
public class MyKsoap2Activityextends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread thread =new Thread(new Runnable() {
@Override
public void run() {
String URL ="http://cjf780426.xicp.net:803/Demo/DEMO1/GBSvr.dll/soap/IGBSvr";
String NAMESPACE ="http://tempuri.org/";
SoapSerializationEnvelope envelope =new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet =true;
HttpTransportSE ht =new HttpTransportSE(URL);
ht.debug =true;
String METHOD_NAME ="GBlogin";
String SOAP_ACTION ="urn:GBSvrIntf-IGBSvr#GBlogin";
SoapObject rpc =new SoapObject(NAMESPACE, METHOD_NAME);
rpc.addProperty("UserName","AllenSTU");
rpc.addProperty("UserPWD","AllenSTU");
envelope.bodyOut = rpc;
envelope.setOutputSoapObject(rpc);
try {
ht.call(SOAP_ACTION, envelope);
System.out.println((String) envelope.getResponse());
}catch (SoapFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
thread.start();
}
}
5. Apache接口
public class MainActivityextends Activity {
private TextView textView;
private Button get,post;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textView = (TextView)findViewById(R.id.textView);
get = (Button)findViewById(R.id.get);
post = (Button)findViewById(R.id.post);
//绑定按钮监听器
get.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//注意：此处ip不能用127.0.0.1或localhost,Android模拟器已将它自己作为了localhost
String uri ="http://192.168.22.28:8080/myapp/http.jsp?parameter=以Get方式发送请求";
textView.setText(get(uri));
}
});
//绑定按钮监听器
post.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String uri ="http://192.168.22.28:8080/myapp/http.jsp";
textView.setText(post(uri));
}
});
}
/**
* 以get方式发送请求，访问web
* @param uri web地址
* @return 响应数据
*/
private static String get(String uri){
BufferedReader reader =null;
StringBuffer sb =null;
String result ="";
HttpClient client =new DefaultHttpClient();
HttpGet request =new HttpGet(uri);
try {
//发送请求，得到响应
HttpResponse response = client.execute(request);
//请求成功
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
reader =new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
sb =new StringBuffer();
String line ="";
String NL = System.getProperty("line.separator");
while((line = reader.readLine()) !=null){
sb.append(line);
}
}
}catch (ClientProtocolException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
finally{
try {
if (null != reader){
reader.close();
reader =null;
}
}catch (IOException e) {
e.printStackTrace();
}
}
if (null != sb){
result = sb.toString();
}
return result;
}
/**
* 以post方式发送请求，访问web
* @param uri web地址
* @return 响应数据
*/
private static String post(String uri){
BufferedReader reader =null;
StringBuffer sb =null;
String result ="";
HttpClient client =new DefaultHttpClient();
HttpPost request =new HttpPost(uri);
//保存要传递的参数
List params =new ArrayList();
//添加参数
params.add(new BasicNameValuePair("parameter","以Post方式发送请求"));
try {
//设置字符集
HttpEntity entity =new UrlEncodedFormEntity(params,"utf-8");
//请求对象
request.setEntity(entity);
//发送请求
HttpResponse response = client.execute(request);
//请求成功
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
System.out.println("post success");
reader =new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
sb =new StringBuffer();
String line ="";
String NL = System.getProperty("line.separator");
while((line = reader.readLine()) !=null){
sb.append(line);
}
}
}catch (ClientProtocolException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
finally{
try {
//关闭流
if (null != reader){
reader.close();
reader =null;
}
}catch (IOException e) {
e.printStackTrace();
}
}
if (null != sb){
result = sb.toString();
}
return result;
}
}
