如何使用 AsyncTask 发送 cookie？

Question

我有一个 Web 服务器，我在其中登录我的 android 应用程序，在登录之后，我将使用名为 token 的字段登录的用户作为 XML 接收。

此令牌用于在下次调用 webService 期间保持会话打开，它可以将令牌作为名为“acrsession”的 cookie 发送，但它似乎不起作用，因为每次我尝试检查我是否登录（使用 get调用名为 currentUser）它返回我被禁止，所以我认为它工作得不好。

这是我的 AsyncTask 类，负责调用服务器。

public String getFileName() {
        return FileName;
    }
    public void setFileName(String fileName) {
        FileName = fileName;
    }
    private String Response;
    private URI uriInfo;
    private String FileName;

    public WebServiceTask(int taskType, Context mContext, String processMessage,String token) {

        this.taskType = taskType;
        this.mContext = mContext;
        this.processMessage = processMessage;
        this.token=token;
    }


    public void addNameValuePair(String name, String value) {
        params.add(new BasicNameValuePair(name, value));
    }

    public void showProgressDialog() {  
        pDlg = new ProgressDialog(mContext);
        pDlg.setMessage(processMessage);
        pDlg.setProgressDrawable(mContext.getWallpaper());
        pDlg.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        pDlg.setCancelable(false);
        pDlg.show();
    }


    @Override
    protected void onPreExecute() {
        //hideKeyboard();
        showProgressDialog();
    }


    protected String doInBackground(String... urls) {
        String url = urls[0];
        String result = "";
        HttpResponse response = doResponse(url);
        if (response == null) {
            return result;
        } else {
            try {
                result = inputStreamToString(response.getEntity().getContent());

            } catch (IllegalStateException e) {
                Log.e(TAG, e.getLocalizedMessage(), e);

            } catch (IOException e) {
                Log.e(TAG, e.getLocalizedMessage(), e);
            }

        }

        return result;
    }

    @Override
    protected void onPostExecute(String response) {     
        this.Response=response;
        pDlg.dismiss();
    }

    // Establish connection and socket (data retrieval) timeouts

        return htpp;
    }

    private HttpResponse doResponse(String url) {

            localContext.setAttribute(ClientContext.COOKIESPEC_REGISTRY, cookieStore);
            localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);// to make sure that cookies provided by the server can be reused
        }
        return localContext;
    }

请告诉我我做错了什么。

提前致谢。

好吧，我终于找到了解决方案，一切正常，但我忘了设置 cookie 域和路径，所以一旦我把它放在了它的工作上。

现在 cookie 创建如下所示：

this.localContext=this.getLocalContext();
BasicClientCookie cookie = new BasicClientCookie("acrsession", this.token);
cookie.setDomain(this.Domain);
cookie.setPath(this.path);
this.cookieStore.addCookie(cookie);
 localContext.setAttribute(ClientContext.COOKIE_STORE, this.cookieStore);

希望对其他人有所帮助。
