Java 如何从客户端获取jsessionId:DefaultHttpClient httpclient=new DefaultHttpClient（）；

但我得到的结果是：[]没有其他。我犯了什么错误，如何获取jsessionId，以便在以后需要将json数据发布到服务器时存储并使用它

---

我需要jsessionId，因为我需要它，稍后我将把我的json数据发布到服务器上。你的方法是正确的，奇怪的是没有存储cookie。可能与？有关，但我的outpur是[]空的。如果您可以检查服务器日志会更好。可能是成功了，服务器没有向您发送任何响应。

HttpHost targetHost = new HttpHost("myhost",8080, "http"); 
CredentialsProvider credsProvider = new BasicCredentialsProvider(); 
credsProvider.setCredentials(new
AuthScope(targetHost.getHostName(), targetHost.getPort()), new
UsernamePasswordCredentials("username", "password"));

// Create AuthCache instance 
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local auth cache
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);

// Add AuthCache to the execution context
HttpClientContext context = HttpClientContext.create();
context.setCredentialsProvider(credsProvider); 
context.setAuthCache(authCache);

HttpGet httpget = new HttpGet("/"); 
try {

    HttpResponse response = httpclient.execute(targetHost, httpget, context);

    System.out.println(httpclient.getCookieStore().getCookies());

} catch (Exception e) {

} finally {
    try { 
        httpget.abort();}catch(Exception e){}
    }
}

private void parseSessionID(HttpResponse response) {
    try {

        Header header = response.getFirstHeader("Set-Cookie");

        String value = header.getValue();
        if (value.contains("JSESSIONID")) {
            int index = value.indexOf("JSESSIONID=");

            int endIndex = value.indexOf(";", index);

            String sessionID = value.substring(
                    index + "JSESSIONID=".length(), endIndex);

            Logger.d(this, "id " + sessionID);

            if (sessionID != null) {
                classStaticVariable= sessionID;
            }

        }
    } catch (Exception e) {
    }
