我在登录一个用 asp 制作的网站时遇到问题......这是我正在使用的代码：
public class MainActivity extends Activity {
Button bottone;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bottone = (Button) findViewById(R.id.button1);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy =
new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
bottone.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// starting new Async Task
try {
login();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
public static void login() throws IOException
{
String loginurl = "https://www.blurum.it/Web/", user, pass;
user = "tester55";
pass = "provapassword321";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(loginurl);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("ctrl_LoginControl$loginView$c01$RPLogin$LoginView$Username", user));
nameValuePairs.add(new BasicNameValuePair("ctrl_LoginControl$loginView$c01$RPLogin$LoginView$Password", pass));
nameValuePairs.add(new BasicNameValuePair("remember", "on"));
nameValuePairs.add(new BasicNameValuePair("ctrl_LoginControl$loginView$c01$RPLogin$LoginView$LoginButton", "Accedi"));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpClient.execute(httpPost);
Log.d("logggd", "response stat code " + response.getStatusLine().getStatusCode());
if (response.getStatusLine().getStatusCode() < 400) {
String cookie = response.getFirstHeader("Cookie")
.getValue();
Log.d("logggdc", "cookie: " + cookie);
// get the contacts page
HttpGet getContacts = new HttpGet("https://www.blurum.it/Web/default.aspx");
getContacts.setHeader("Cookie", cookie);
response = httpClient.execute(getContacts);
InputStream ins = response.getEntity().getContent();
BufferedReader in = new BufferedReader(new InputStreamReader(
ins));
String inputLine;
while ((inputLine = in.readLine()) != null) {
Log.d("logggd1", " " + inputLine);
}
in.close();
} else {
Log.d("logggd2", "Response error: "
+ response.getStatusLine().getStatusCode());
}
}
}
但是我的应用程序崩溃了，所以我在代码中找不到错误......这是logcat：

我使用 Tamper Data 在 Firefox 中将发布的数据提取到服务器，这是一个屏幕，我认为登录分为 2 个帖子，这里是屏幕：http: //i.stack.imgur.com/GZiZ0.png http ://i.stack.imgur.com/FKH3P.png
我不确定我是否必须发送第一页或第二个帖子数据，这可能是错误吗？谢谢。
