從我的Android應用程序中，我想請求帶有GET參數的URL並閱讀響應。在要求我必須添加一個兩個頭的參數（鍵和DT）。我寫了一些代碼，但我有404個error.this是我的源android發送帶有標頭的HTTP GET請求
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String pass = "pass";
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); // 2008-03-09T16:05:07
Date date = new Date();
System.out.println(dateFormat.format(date));
Calendar cal = Calendar.getInstance();
String gettime = dateFormat.format(cal.getTime());
System.out.println(gettime);
String Key = md5(pass + cal.getTime());
System.out.println(Key);
// Log.e("Md5", gettime);
SendHttpGetRequest(Key, gettime);
}
private static String md5(String s) {
try {
// Create MD5 Hash
MessageDigest digest = java.security.MessageDigest
.getInstance("MD5");
digest.update(s.getBytes());
byte messageDigest[] = digest.digest();
// Create Hex String
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < messageDigest.length; i++)
hexString.append(Integer.toHexString(0xFF & messageDigest[i]));
return hexString.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return "";
}
public void SendHttpGetRequest(final String mykey, final String mydt) {
class CheckLattery extends AsyncTask<String, Void, String> {
ProgressDialog pDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setCancelable(false);
pDialog.show();
pDialog.setContentView(R.layout.custom_progressdialog);
}
@Override
protected String doInBackground(String... params) {
HttpClient httpClient = getNewHttpClient();
try {
HttpGet httpGet = new HttpGet(
"************");
httpGet.addHeader("key", mykey);
httpGet.addHeader("dt", mydt);
HttpResponse httpResponse = httpClient.execute(httpGet);
System.out.println("httpResponse");
InputStream inputStream = httpResponse.getEntity()
.getContent();
InputStreamReader inputStreamReader = new InputStreamReader(
inputStream);
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader);
StringBuilder stringBuilder = new StringBuilder();
String bufferedStrChunk = null;
while ((bufferedStrChunk = bufferedReader.readLine()) != null) {
stringBuilder.append(bufferedStrChunk);
}
System.out.println("Returning value of doInBackground :"
+ stringBuilder.toString());
return stringBuilder.toString();
} catch (ClientProtocolException cpe) {
System.out
.println("Exception generates caz of httpResponse :"
+ cpe);
cpe.printStackTrace();
} catch (IOException ioe) {
System.out
.println("Second exception generates caz of httpResponse :"
+ ioe);
ioe.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (pDialog != null) {
pDialog.dismiss();
pDialog = null;
}
Log.wtf("result", result + "res");
}
}
CheckLattery latterychek = new CheckLattery();
latterychek.execute();
}
public HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore
.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory
.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(
params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
}
在我的選擇我有問題頭部parameters.i不知道什麼是錯誤的..我第一次在httpget方法中使用頭參數 如果有人知道解決方案請幫助我謝謝
同樣的請求與來自提琴手或郵遞員的靜態變量，你也得到404？ –
