Android中Http加载如何得到Cookie和 WebView 加载网页如何得到的Cookie

Posted 2020-08-26 切切歆语

最近做项目在手机端登录Http请求和 WebView 记载登录获取Cookie信息,可查看Cookie信息。

如图：

Http请求获取Cookie信息：

  public static String request(String httpUrl, String params, Context context) {
        BufferedReader reader = null;
        String result = null;
        String httpurl = " http://xwwscs.com";
        StringBuffer sbf = new StringBuffer();
        try {
            URL url = new URL(httpurl + "/app.php");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Cookie", CookieUtil.getParam(context).toString());
            connection.setConnectTimeout(3000);
            // 是否输入参数
            connection.setDoOutput(true);
            byte[] bypes = params.toString().getBytes();
            connection.getOutputStream().write(bypes);// 输入参数
           connection.connect();
            InputStream is = connection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String strRead = null;
            while ((strRead = reader.readLine()) != null) {
                sbf.append(strRead);
                sbf.append("\r\n");
            }
            reader.close();
            Map<String, List<String>> cookie_map = connection.getHeaderFields();
            List<String> cookies = cookie_map.get("Set-Cookie");
            if (null != cookies && 0 < cookies.size()) {
                String s = "";
                for (String cookie : cookies) {
                    if (s.isEmpty()) {
                        s = cookie;
                    } else {
                        s += ";" + cookie;
                    }
                }
                Log.i("cookie", s);
            }
            result = sbf.toString();
        } catch (Exception e) {
            result = "error";
            e.printStackTrace();
        }
        return result;
    }
}

 

WebView加载网页获取Cookie

        webView.setWebViewClient(new WebViewClient()
                {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view,
                    String url) {
                // TODO Auto-generated method stub
                return super.shouldOverrideUrlLoading(view, url);
            }
            @Override
            public void onPageFinished(WebView view, String url) {
                CookieManager cookieManager = CookieManager.getInstance();
                String CookieStr = cookieManager.getCookie(url);
                if(CookieStr!=null)
                {
                    Log.i("cookie", CookieStr);
                }
                super.onPageFinished(view, url);
            }
            
          });
