刚开始学android，做客户端实现登陆功能的时候，使用httpclinet连接返回了Request method 'POST' not supported的错误,
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); editText1=(EditText) findViewById(R.id.editText1); editText2=(EditText) findViewById(R.id.editText2); textView=(TextView) findViewById(R.id.textview); button=(Button) findViewById(R.id.button1); httpClient = new DefaultHttpClient(); button.setOnClickListener(new OnClickListener() { public void onClick(View v) { System.out.println("username="+editText1.getText()+"&password="+editText2.getText()); readNet("http://192.168.202.246/iot/login","username="+editText1.getText()+"&password="+editText2.getText()); } }); } public void readNet(String URL,String inString){ new AsyncTask<String, Void, String>(){ @Override protected String doInBackground(String... params) { String urlString=params[0]; HttpPost post=new HttpPost(urlString); StringEntity entitytrString; try { entitytrString = new StringEntity(params[1]); post.setEntity(entitytrString); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } try { HttpResponse httpResponse=httpClient.execute(post); String valString=EntityUtils.toString(httpResponse.getEntity()); System.out.println(valString); return valString; } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } @Override protected void onPostExecute(String result) { // TODO Auto-generated method stub textView.setText(result); } }.execute(URL,inString); } }

配置了android访问网络的权限么？
有的
@219饮水机:
感觉你的URL用的GET方式，但是发送请求是用的HTTPPOST,是不是二者不匹配导致的？
1 Log.i(TAG, "POST request"); 2 // 先获取用户名和年龄 3 String name = mNameText.getText().toString(); 4 String age = mAgeText.getText().toString(); 5 6 NameValuePair pair1 = new BasicNameValuePair("username", name); 7 NameValuePair pair2 = new BasicNameValuePair("age", age); 8 9 List<NameValuePair> pairList = new ArrayList<NameValuePair>(); 10 pairList.add(pair1); 11 pairList.add(pair2); 12 13 try 14 { 15 HttpEntity requestHttpEntity = new UrlEncodedFormEntity( 16 pairList); 17 // URL使用基本URL即可，其中不需要加参数 18 HttpPost httpPost = new HttpPost(baseURL); 19 // 将请求体内容加入请求中 20 httpPost.setEntity(requestHttpEntity); 21 // 需要客户端对象来发送请求 22 HttpClient httpClient = new DefaultHttpClient(); 23 // 发送请求 24 HttpResponse response = httpClient.execute(httpPost); 25 // 显示响应 26 showResponseResult(response); 27 } 28 catch (Exception e) 29 { 30 e.printStackTrace(); 31 }

建议不要再使用HttpClient，使用HttpURLConnection代替HttpClient，原因是Android 6.0不再支持HttpClient
