请求不会在PersistentCookieStore中使用已保存的Cookie

问题描述

当我宣布一个cookie商店时，我修复了我的应用程序中的崩溃和错误，但它没有保存cookie或在其他位置出现问题。

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.

首先我称这两行：

AsyncHttpClient client = new AsyncHttpClient();
PersistentCookieStore myCookieStore;

然后我有一个POST：

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);
            }
        }
    });

}

然后它应该保存Logincookies并将其用于GET请求：

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);
        }
    });
}

但它不使用cookies。当我执行GET请求时，我已经注销了。

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

编辑：我忘了说我使用了本教程中的lib：

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

推荐答案

我认为问题是你在请求完成后设置了cookie存储（在 onSuccess 方法中）。在提出请求之前尝试设置它：

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() {

你也是在每个请求上创建一个新的cookie存储。如果你做多个请求会发生什么？它会创建一个新的cookie存储并使用它（而新的cookie存储将没有你的cookie）。尝试移动这部分代码到你的构造函数：

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);

然后将其从其他函数中删除。

Then remove it from the other functions.
