Request doesn't use saved cookies in Persisten

问题:

I fixed the crash and error in my app when I declared a cookie store, but it doesn't save the cookies or something went wrong at an other position.

At first I call these 2 lines:

AsyncHttpClient client = new AsyncHttpClient();
PersistentCookieStore myCookieStore;

And then I have a POST:

public void postRequestLogin(String url, RequestParams params) {
    myCookieStore = new PersistentCookieStore(this);
    client.post(url, params, new AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(String response) {
            client.setCookieStore(myCookieStore);
            System.out.println(response);

            if(response.contains("Login successful!")) {
                TextView lblStatus = (TextView)findViewById(R.id.lblStatus);
                lblStatus.setText("Login successful!");
                getRequest("url");
            } else {
                TextView lblStatus = (TextView)findViewById(R.id.lblStatus);
                lblStatus.setText("Login failed!");
                TextView source = (TextView)findViewById(R.id.response_request);
                source.setText(response);
            }
        }
    });

}

Then it should save the Logincookies and use it for the GET Request:

public void getRequest(String url) {
    myCookieStore = new PersistentCookieStore(this);
    client.get(url, new AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(String response) {
            client.setCookieStore(myCookieStore);
            System.out.println(response);
            TextView responseview = (TextView) findViewById(R.id.response_request);
            responseview.setText(response);
        }
    });
}

But it doesn't use the cookies. When I do the GET Request I'm already logged out.

Edit: I forgot to say that I use a lib from this tutorial: http://loopj.com/android-async-http/

I think the problem is that you set the cookie store after the request has already completed (in the onSuccess method). Try setting it before you make that request:

myCookieStore = new PersistentCookieStore(this);
client.setCookieStore(myCookieStore);
client.post(url, params, new AsyncHttpResponseHandler() {

You're also creating a new cookie store on every request. What happens if you do more than one request? It will create a new cookie store and use it (and the new cookie store won't have your cookies). Try moving this part of the code to your constructor:

myCookieStore = new PersistentCookieStore(this);
client.setCookieStore(myCookieStore);

Then remove it from the other functions.
