[英]How to send Token with POST request to Django REST api from Android App?
[英]How send http request in android app to access REST API
任何人都可以解決我的問題。 我想在android中發送一個http請求來訪問REST API(PHP)..
謝謝

public class AndroidApp extends Activity {
String URL = "http://the/url/here";
String result = "";
String deviceId = "xxxxx" ;
final String tag = "Your Logcat tag: ";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final EditText txtSearch = (EditText)findViewById(R.id.txtSearch);
txtSearch.setOnClickListener(new EditText.OnClickListener(){
public void onClick(View v){txtSearch.setText("");}
});
final Button btnSearch = (Button)findViewById(R.id.btnSearch);
btnSearch.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v) {
String query = txtSearch.getText().toString();
callWebService(query);
}
});
} // end onCreate()
public void callWebService(String q){
HttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet(URL + q);
request.addHeader("deviceId", deviceId);
ResponseHandler<string> handler = new BasicResponseHandler();
try {
result = httpclient.execute(request, handler);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
httpclient.getConnectionManager().shutdown();
Log.i(tag, result);
} // end callWebService()
}
它基本上取決於你需要什么,但假設一個簡單的POST請求與JSON主體它看起來像這樣(我建議使用Apache HTTP庫)。
HttpPost mRequest = new HttpPost(<your url>);
DefaultHttpClient client = new DefaultHttpClient();
//In case you need cookies, you can store them with PersistenCookieStorage
client.setCookieStore(Application.cookieStore);
try {
HttpResponse response = client.execute(mRequest);
InputStream source = response.getEntity().getContent();
Reader reader = new InputStreamReader(source);
//GSON is one of the best alternatives for JSON parsing
Gson gson = new Gson();
User user = gson.fromJson(reader, User.class);
//At this point you can do whatever you need with your parsed object.
} catch (IOException e) {
mRequest.abort();
}
最后,我建議您在任何類型的后台線程(執行程序,線程,異步任務等)中運行此代碼
