將cookie添加到HTTP請求

Question

我正在嘗試添加帶有GUID的cookie來識別用戶，但是當我在測試腳本上運行時，我的代碼似乎沒有發送任何cookie。

我的Java代碼：

    public void search(String q, int o) {
    final String query = q;
    final int offset = o;
    Thread searchThread = new Thread() {
        public void run() {
            try {
                DefaultHttpClient httpClient = new DefaultHttpClient();
                BasicHttpContext httpContext = new BasicHttpContext();
                CookieStore cookieStore = new BasicCookieStore();
                httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
                cookieStore.addCookie(new BasicClientCookie("remixsid", guid));
                httpClient.setCookieStore(cookieStore);
                HttpPost httpPost = new HttpPost("http://192.168.1.43/test/test.php?section=audio&q=" + URLEncoder.encode(query, HTTP.UTF_8) + "&offset=" + offset);
                //HttpPost httpPost = new HttpPost("http://vkontakte.ru/gsearch.php?section=audio&q=" + URLEncoder.encode(query, HTTP.UTF_8) + "&offset=" + offset);
                HttpResponse response = httpClient.execute(httpPost, httpContext);
                String responseBody = EntityUtils.toString(response.getEntity());
                System.out.print(responseBody);
            } catch(Exception e) {
                System.out.println(e.toString());
            }
        }
    };
    searchThread.run();
}

我的PHP代碼測試cookie：

<?php
$cookies = $_COOKIE;

if(!count($cookies) > 0)
    echo 'No cookies!';

foreach ($cookies as $key=>$val)
    echo "$key--> $val";

?>

使用以下代碼檢索GUID：

    public void login(String usr, String pass) {
    logout();
    final String username = usr;
    final String password = pass;
    Thread loginThread = new Thread() {
        public void run() {
            try {
                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost("http://login.vk.com/?act=login&email=" + URLEncoder.encode(username, HTTP.UTF_8) + "&pass=" + URLEncoder.encode(password, HTTP.UTF_8));
                httpClient.execute(httpPost);
                List<Cookie> cookies = httpClient.getCookieStore().getCookies();
                for(Cookie cookie : cookies) {
                    System.out.println("Cookie: " + cookie.toString());
                    if(cookie.getName().contains("remixsid"))
                        guid = cookie.getValue();
                }
            } catch(Exception e) {
                System.out.println(e.toString());
                System.out.println("An error occured");
                if(loginHandler != null)
                    loginHandler.onLoginError(e);
                return;
            }
            if(!isLoggedIn()) {
                System.out.println("User credentials invalid");
                if(loginHandler != null)
                    loginHandler.onLoginInvalidCredentials();
                return;
            }
            if(loginHandler != null)
                loginHandler.onLoginSuccess();
            System.out.println("Login successfull GUID is: " + guid);
        }
    };
    loginThread.start();
}

手動設置cookie標頭似乎工作...

    public void search(String q, int o) {
    final String query = q;
    final int offset = o;
    Thread searchThread = new Thread() {
        public void run() {
            try {
                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost("http://192.168.1.43/test/test.php");
                //HttpPost httpPost = new HttpPost("http://vkontakte.ru/gsearch.php?section=audio&q=" + URLEncoder.encode(query, HTTP.UTF_8) + "&offset=" + offset);
                httpPost.setHeader("Cookie", "remixsid=" + guid);
                HttpResponse response = httpClient.execute(httpPost);
                String responseBody = EntityUtils.toString(response.getEntity());
                System.out.println(responseBody);
            } catch(Exception e) {
                System.out.println(e.toString());
            }
        }
    };
    searchThread.start();
}

幾點意見和建議：

1. 您沒有向cookie添加任何路徑信息 。 您可以使用BasicClientCookie.setPath()方法。
2. 試圖讀取此cookie 的php腳本的路徑是什么？
3. 當cookie設置在根路徑 （ / ）時，只有它可用於所有其他服務器端程序。
4. 將cookie的路徑設置為root或使cookie的路徑與PHP腳本的路徑相同。

編輯：

我錯過了域名部分。 您還需要設置cookie域。 假設您的PHP腳本運行在http://mysite/myscript.php這里mysite是域（如果您在本地框中運行腳本，則可能是localhost ）。 使用BasicClientCookie.setDomain()設置cookie域。

要理解這一點，假設您的http-client lib作為瀏覽器與網站交互。 瀏覽器存儲來自許多站點的cookie，但在向特定站點發出請求時，它僅發送從該特定站點收到的cookie。

如果未設置域，則lib不會將cookie發送到該主機。
