java android 访问DELPHI 的DATASNAP

最新版的DELPHI开发DATASNAP非常简单便捷，DataSnap的REST风格和对JSON的支持,使之成为服务器端开发的神器。

一、DATASNAP服务器中的方法：

TServerMethods1 = class(TDSServerModule)

Dspwire: TDataSetProvider;

ADOQuery1: TADOQuery;

private

{ Private declarations }

public

{ Public declarations }

function Askname(Sid:String):string; //根据会员编号查姓名

....

二、JAVA安卓作为客户端

final String cstr=new String("http://192.168.1.123:8080/datasnap/rest/TServerMethods1/Askname");

final EditText et=(EditText)findViewById(R.id.editText1);

final TextView tv=(TextView)findViewById(R.id.textView1);

Button bt1=(Button)findViewById(R.id.button1);

bt1.setOnClickListener(new OnClickListener(){

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

HttpClient client=new DefaultHttpClient();

HttpGet httpGet=new HttpGet(cstr+"/"+et.getText().toString());

HttpResponse response = null;

response = client.execute(httpGet);

inputStream inputStream=null;

inputStream=response.getEntity().getContent();

StringBuffer buffer = new StringBuffer();

BufferedReader bufferReader = new BufferedReader( new InputStreamReader(inputStream));

String str = new String("");

while ((str = bufferReader.readLine()) != null) {

buffer.append(str) };

bufferReader.close();

tv.setText(buffer.toString());

}}

剩下的就是解析JSON了。

三、用DELPHI 做android 客户端的话,访问DATASNAP就非常简单了...
