如何设置从android应用程序发送数据到我们的服务器的请求头

如何设置HTTP标头从我们的Android应用程序发送JSON对象什么types的头我们想用于发送数据从客户端到服务器。为什么我们正在使用头,什么是重要的。

public class HomeLayoutActivity extends Activity implements OnClickListener{ private EditText value; private Button btn; private ProgressBar pb; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.home_layout); value=(EditText)findViewById(R.id.editText1); btn=(Button)findViewById(R.id.button1); pb=(ProgressBar)findViewById(R.id.progressBar1); pb.setVisibility(View.GONE); btn.setOnClickListener(this); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.home_layout, menu); return true; } public void onClick(View v) { // TODO Auto-generated method stub if(value.getText().toString().length()<1){ // out of range Toast.makeText(this, "please enter something", Toast.LENGTH_LONG).show(); }else{ pb.setVisibility(View.VISIBLE); new MyAsyncTask().execute(value.getText().toString()); } } private class MyAsyncTask extends AsyncTask<String, Integer, Double>{ @Override protected Double doInBackground(String... params) { // TODO Auto-generated method stub postData(params[0]); return null; } protected void onPostExecute(Double result){ pb.setVisibility(View.GONE); Toast.makeText(getApplicationContext(), "command sent", Toast.LENGTH_LONG).show(); } protected void onProgressUpdate(Integer... progress){ pb.setProgress(progress[0]); } public void postData(String valueIWantToSend) { // Create a new HttpClient and Post Header HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://floating-wildwood-1154.herokuapp.com/posts/create_a_post"); try { // Add your data List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); nameValuePairs.add(new BasicNameValuePair("content", valueIWantToSend)); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); // Execute HTTP Post Request HttpResponse response = httpclient.execute(httppost); } catch (ClientProtocolException e) { // TODO Auto-generated catch block } catch (IOException e) { // TODO Auto-generated catch block } } } } 

我不知道如何设置请求标头发送数据从客户端到服务器端。在我的代码如何设置请求标头

你可以看看这个

你可以使用这个

 HttpPost post = new HttpPost( "http://wwww.testserver.com/userAddMoney" ); post.addHeader( "X-Testing-Auth-Secret" , "kI7wGju76kjhJHGklk76" ); 

您可以使用

 try { HttpClient client = new DefaultHttpClient(); String getURL = "http://helloworld.com/getmethod.aspx?id=1&method=getData"; HttpGet httpGet = new HttpGet(getURL); **httpGet .setHeader("Content-Type", "application/x-zip");** HttpResponse response = client.execute(httpGet); HttpEntity resEntity = response.getEntity(); if (resEntity != null) { //parse response. Log.e("Response",EntityUtils.toString(resEntity)); } } catch (Exception e) { e.printStackTrace(); } 

尝试这个:

 HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://floating-wildwood-1154.herokuapp.com/posts/create_a_post"); // Add Headers httppost.addHeader("key1", "value1"); httppost.addHeader("key2", "value2"); try { // Add your data List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); nameValuePairs.add(new BasicNameValuePair("content", valueIWantToSend)); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); // Execute HTTP Post Request HttpResponse response = httpclient.execute(httppost); } catch (ClientProtocolException e) { // TODO Auto-generated catch block } catch (IOException e) { // TODO Auto-generated catch block } 

我在.NET中编写了一个Web服务,然后在我的android应用程序中使用kso​​ap2将数据发送到我的服务器。

看看ksoap2-android:

我build议添加这个库:

https://oss.sonatype.org/content/repositories/ksoap2-android-releases/com/google/code/ksoap2-android/ksoap2-android-assembly/3.0.0/ksoap2-android-assembly-3.0.0- JAR-与-dependencies.jar

也承载所有的依赖。
