ANDROID：web视图之间共享会话的HttpClient | web视图之间共享会话的HttpClient

本文介绍了ANDROID：web视图之间共享会话的HttpClient的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我居然在我的WebView一个登录会话。但我用同样的HttpClient从网络上发送和获取数据。我在网上看到，这是不可能得到的WebView的内容，所以我需要用我的HttpClient从Web服务获取数据。

现在的问题是，这个Web服务使用会话......而我会在我的WebView，所以HttpClient的没有它，我不能访问web服务的内容。

我看到有关这个问题的很多帖子，但我不明白的解决方案。

下面是我做我的onPageStarted：

  CookieManager经理= CookieManager.getInstance（）;
Log.i（URL，网址）;
Log.i（曲奇，mgr.getCookie（mywebsite.com））;
串cookie_string = mgr.getCookie（mywebsite.com）;
如果（cookie_string.length（）→1）{
    。Data.instance（）获得preF（）编辑（）putString（曲奇，cookie_string）.commit（）。
}

我看到，我有这样的事情，所以我希望那些有会议太：（我删除的数量）

  __ UTMA = ......（数量）......;

__utmc =号;

__utmz = number.utmcsr =（直接）| utmccn =（直接）| utmcmd =（无）;

wt3_eid =％人数％人数;

wt3_sid =％数量

话，我不知道该怎么做才能在我的HttpClient设置这个cookie。我尝试，但没有成功：

  HttpClient的客户端=新DefaultHttpClient（）;
BasicCookieStore的CookieStore =新BasicCookieStore（）;
字符串login_cookie_string = Data.instance（）得到preF（）的getString（曲奇，）;
的String [] cookie_parts = NULL;
如果（login_cookie_string.length（）大于0）
{

    //debug_view.setText(login_cookie_string）;
    Log.d（曲奇，login_cookie_string）;
    cookie_parts = login_cookie_string.split（;）;

    对于（INT T = 0; T＆LT; cookie_parts.length;吨++）
    {
        的String [] cookieContent = cookie_parts [T] .split（=）;
        饼干login_cookie =新BasicClientCookie（cookieContent [0]，cookieContent [1]）;
        （（BasicClientCookie）login_cookie）.setDomain（mywebsite.com）;
        cookieStore.addCookie（login_cookie）;
    }

}
（（AbstractHttpClient）客户端）.setCookieStore（CookieStore的）;

解决方案

所以，这是我做过什么和它的工作对我来说 -

 的Htt prequestBase请求=新HTTPGET（URI）;
request.addHeader（曲奇，getCookieFromAppCookieManager（uri.toString（）））;

现在的implmentation为getCookieFromAppCookieManager如下 - 中国该方法得到的Cookie从应用程序CookieManager一个给定的URL。应用CookieManager器管理应用程序的web视图实例的cookie。

  @参数的URL该Cookie的请求的URL
@返回值的cookie作为一个字符串，使用曲奇HTTP请求头的格式
@throws MalformedURLException的


公共静态字符串getCookieFromAppCookieManager（字符串URL）抛出MalformedURLException的{
    CookieManager cookieManager = CookieManager.getInstance（）;
    如果（cookieManager == NULL）
        返回null;
    字符串rawCookieHeader = NULL;
    URL parsedURL =新的网址（URL）;

    从Android应用程序CookieManager此URL //提取设置Cookie标头值
    rawCookieHeader = cookieManager.getCookie（parsedURL.getHost（））;
    如果（rawCookieHeader == NULL）
        返回null;
    返回rawCookieHeader;
}

I have actually a logged session in my WebView.But i use also httpclient to send and get data from the web. I saw on the internet that it's impossible to get the content of a WebView, so i needed to use my httpclient to get data from a webservice.

The problem is that this webservice uses sessions... and my session is in my WebView, so the httpclient doesn't have it and i can't access the content of the webservice.

I see many posts about this problem but i didn't understand the solution.

Here is what i did on my onPageStarted :

CookieManager mgr = CookieManager.getInstance();
Log.i( "URL", url );
Log.i("Cookie",mgr.getCookie("mywebsite.com"));
String cookie_string = mgr.getCookie("mywebsite.com");
if(cookie_string.length() > 1) {
    Data.instance().getPref().edit().putString("cookie",cookie_string).commit();
}

I saw that i have this kind of things, so i hope those include session too :(i remove the number)

__utma=......(number)......;

__utmc=number;

__utmz=number.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none);

wt3_eid=%number%number;

wt3_sid=%number

Then i don't know what to do in order to set this cookie in my httpclient. I try that, with no success :

HttpClient client = new DefaultHttpClient();
BasicCookieStore cookieStore = new BasicCookieStore();
String login_cookie_string = Data.instance().getPref().getString("cookie", "");
String[] cookie_parts = null;
if(login_cookie_string.length()> 0)
{

    //debug_view.setText(login_cookie_string);
    Log.d("COOKIE", login_cookie_string);
    cookie_parts = login_cookie_string.split(";");

    for(int t=0;t < cookie_parts.length;t++)
    {
        String[] cookieContent = cookie_parts[t].split("=");
        Cookie login_cookie = new BasicClientCookie(cookieContent[0],cookieContent[1]);
        ((BasicClientCookie) login_cookie).setDomain("mywebsite.com");
        cookieStore.addCookie(login_cookie);
    }

}
((AbstractHttpClient) client).setCookieStore(cookieStore);

解决方案

So , this is what I did and it worked for me -

HttpRequestBase request = new HttpGet(uri);
request.addHeader("Cookie", getCookieFromAppCookieManager(uri.toString()));

Now the implmentation for the getCookieFromAppCookieManager is as follows -
The method gets the cookies for a given URL from the application CookieManager. The application CookieManager manages the cookies used by an application's WebView instances.

@param url the URL for which the cookies are requested
@return value the cookies as a string, using the format of the 'Cookie' HTTP request header
@throws MalformedURLException


public static String getCookieFromAppCookieManager(String url) throws MalformedURLException {
    CookieManager cookieManager = CookieManager.getInstance();
    if (cookieManager == null)
        return null;
    String rawCookieHeader = null;
    URL parsedURL = new URL(url);

    // Extract Set-Cookie header value from Android app CookieManager for this URL
    rawCookieHeader = cookieManager.getCookie(parsedURL.getHost());
    if (rawCookieHeader == null)
        return null;
    return rawCookieHeader;
}
