问题描述
这是一个后续问题的<一个href="http://stackoverflow.com/questions/3550593/sending-html-commands-over-httpclient-android">http://stackoverflow.com/questions/3550593/sending-html-commands-over-httpclient-android ，我已经成功地发布到服务器的和接收的200 code，但是当我试图移动到另一页不承认，我已经登录。我想知道，如果它是一个会话问题，或者如果我需要跟随在POST后重定向。我怎么会去下面的重定向？再次任何帮助是极大的AP preciated。下面是一个简单的HttpClient / POST应用程序从我的例子，以帮助我快速测试的任何更改创建的。
This is a follow up question of http://stackoverflow.com/questions/3550593/sending-html-commands-over-httpclient-android , I have successfully POSTed to the server and recieved 200 code but when I attempt to move to another page it does not recognize that I have logged in. I am wondering if it is a session issue or if i need to follow the redirect after the POST. How would I go about following a redirect? Again any help is greatly appreciated. Here is a simple HttpClient / POST app I created from examples in order to help me quickly test any changes.
public class HttpClientTest extends Activity{
HttpClient client = new DefaultHttpClient();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button btnFetch = (Button)findViewById(R.id.button);
final TextView txtResult = (TextView)findViewById(R.id.content);
final Button login = (Button)findViewById(R.id.button2);
btnFetch.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v){
getRequest(txtResult);
}
});
login.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v){
try {
login(txtResult);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
public void getRequest(TextView txtResult){
HttpGet request = new HttpGet("http://gc.gamestotal.com/i.cfm?f=com_empire&cm=3");
try{
HttpResponse response = client.execute(request);
txtResult.setText(Parser.request(response));
}catch(Exception ex){
txtResult.setText("Failed!");
}
}
public void login(TextView txtResult) throws UnsupportedEncodingException, IOException{
String action = "i.cfm?&1028&p=login&se=4";
String yourServer = "http://gc.gamestotal.com/";
HttpPost post = new HttpPost(yourServer + action);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("nic", "user"));
params.add(new BasicNameValuePair("password", "password"));
params.add(new BasicNameValuePair("server", "4"));
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params, "UTF-8");
post.setEntity(entity);
try{
HttpResponse response = client.execute(post);
txtResult.setText(response.getEntity().toString());
}catch(Exception ex){
txtResult.setText("Failed!");
}
}
}
我第一次preSS UI上的登录按钮，让我的HTTP / 1.1 200 OK响应code，但是当我preSS的btnFetch按钮，给我发来一个网页，必须在其中但登录后才能访问，我得到的尚未登录页面。任何想法？
I first press the login button on the UI which gives me the Http/1.1 200 OK response code, but when I press the btnFetch button which sends me to a page in which you must but logged in to access, I get the not logged in page. Any ideas?
推荐答案
在大量的研究和许多例子后，我终于成功地登录到该网站，我试图。显然，这是一个问题，我没有从响应消费实体，即饼干。我创建了一个简单的活动谁的主要目的是GET和POST到网站，然后吐了出来，结果到LogCat中。或许，这可以帮助别人。
After much research and many examples later I have finally managed to login to the site I was attempting. Apparently It was an issue with me not consuming the entity from the response, ie the cookies. I created a simple activity who's main purpose is to GET and POST to the site then spit out the result into LogCat. Perhaps this may help others.
public class HttpClientTest extends Activity{
DefaultHttpClient client = new DefaultHttpClient();
HttpGet request;
HttpEntity entity;
List<Cookie> cookies;
HttpResponse response;
HttpPost post;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
getRequest();
} catch (Exception e) {
Log.d("My Activity", "Failed");
e.printStackTrace();
}
}
public void getRequest() throws Exception
{
final String TAG = "MyActivity";
request = new HttpGet("http://some.site.com/");
response = client.execute(request);
entity = response.getEntity();
Log.d(TAG, "Login form get: " + response.getStatusLine());
if(entity != null)
{
entity.consumeContent();
}
Log.d(TAG, "Initial set of cookies:");
cookies = client.getCookieStore().getCookies();
if (cookies.isEmpty())
{
Log.d(TAG, "None");
}
else
{
for(int i = 0; i<cookies.size(); i++)
{
Log.d(TAG, "- " + cookies.get(i));
}
}
String action = "i.cfm?&1028&p=login&se=4";
String yourServer = "http://some.site.com/";
post = new HttpPost(yourServer + action);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("nic", "username"));
params.add(new BasicNameValuePair("password", "password"));
params.add(new BasicNameValuePair("server", "4"));
post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
response = client.execute(post);
entity = response.getEntity();
Log.d(TAG, "Login form get: " + response.getStatusLine());
if(entity != null){
entity.consumeContent();
}
Log.d(TAG, "Post logon cookies:");
cookies = client.getCookieStore().getCookies();
if (cookies.isEmpty())
{
Log.d(TAG, "None");
}
else
{
for (int i = 0; i < cookies.size(); i++)
{
Log.d(TAG, "- " + cookies.get(i));
}
}
request = new HttpGet("http://some.site.com/i.cfm?f=com_empire&cm=3");
response = client.execute(request);
Log.d(TAG, "Check for login: " + Parser.request(response));
if(entity != null)
{
entity.consumeContent();
}
}
}
最后一个日志，Log.d（TAG，检查登入：+ Parser.request（响应））;打印出网站的HTML所经历一个解析类，这是我用来验证，这是逸岸一个页面，需要登录成功
the last log, Log.d(TAG, "Check for login: " + Parser.request(response)); prints out the html of the site by going through a parser class, which I used to verify that it was infact a page that required successful login
