Java （Android）HttpClient、URL和HttpURLConnection中的Cookie问题

我将在android应用程序的注册表中添加验证码验证。但我发现服务器向我发出信号，表示没有会话。最后，我发现我的应用程序的cookie没有存储任何内容

即使验证正确，我也无法注册帐户。我确信我的php服务器没有问题，因为我已经在浏览器中测试过了

我已经建立了三种类型的连接来测试cookie问题

1） HttpClient

HttpResponse response = httpclient.execute(httppost);

2） 网址

3） HttpURLConnection

private void send_post(HttpURLConnection connection,String variable_set) throws Exception
{
    connection.setDoOutput(true);
    connection.setDoInput(true);
    connection.setInstanceFollowRedirects(false); 
    connection.setRequestMethod("POST"); 
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
    connection.setRequestProperty("charset", "utf-8");
    connection.setRequestProperty("Content-Length", "" + Integer.toString(variable_set.getBytes().length));
    connection.setUseCaches(false);

    DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
    wr.writeBytes(variable_set);
    wr.flush();
    wr.close();
}

另外，我将此代码添加到设置cookie中

CookieManager cookieManager = new CookieManager();  
    CookieHandler.setDefault(cookieManager);

不幸的是，只有使用cookie和服务器的HttpURLConnection成功显示存在一些会话变量。然而，我的应用程序主要使用URL和HttpClient

有人能告诉我如何在HttpClient和URL中启用cookie吗？

下面是一个示例代码，用于在Android中将JSESSIONID（Apache Tomcat服务器的）设置为cookie。希望这将为您提供一些在PHP中执行类似过程的想法：

DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.setCookieStore(new BasicCookieStore());
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID<<or your variable name>>", <<ACTUAL VALUE>>);
cookie.setDomain(<<SET YOUR DOMAIN NAME HERE>>);
cookie.setPath("/");
httpClient.getCookieStore().addCookie(cookie);
HttpEntity httpEntity = null;
HttpResponse httpResponse = null;
// Checking http request method type
if (method == POST) {
    HttpPost httpPost = new HttpPost(url);
    httpPost.setHeader("Accept", "application/json"); //use text/plain if response if HTTP response is plain text
    httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");                
    if (formData != null) {
        httpPost.setEntity(new UrlEncodedFormEntity(formData, HTTP.UTF_8));
    }
    httpResponse = httpClient.execute(httpPost);
} else if (method == GET) {
    if (formData != null) {
        String paramString = URLEncodedUtils.format(formData, "utf-8");
        url += "?" + paramString;
    }
    HttpGet httpGet = new HttpGet(url);
    httpResponse = httpClient.execute(httpGet);
}

status_code = httpResponse.getStatusLine().getStatusCode();
httpEntity = httpResponse.getEntity();
Log.i("Status Code After Login", "> >status code > >" + status_code + "> >url > >"+url);
if(status_code==200)
    response = EntityUtils.toString(httpEntity);
else
    response="fail";

<<response will contain the final HTTP response>>

DefaultHttpClient-httpClient=newdefaulthttpclient（）；
setCookieStore（新的BasicCookieStore（））；
BasicClientCookie=新的BasicClientCookie（“JSESSIONID”）；
cookie.setDomain（）；
cookie.setPath（“/”）；
httpClient.getCookieStore（）.addCookie（cookie）；
HttpEntity HttpEntity=null；
HttpResponse HttpResponse=null；
//检查http请求方法类型
if（方法==POST）{
HttpPost HttpPost=新的HttpPost（url）；
setHeader（“Accept”，“application/json”）；//如果HTTP响应为纯文本，则使用text/plain if response
setHeader（“内容类型”，“应用程序/x-www-form-urlencoded”）；
if（formData！=null）{
setEntity（新的UrlEncodedFormEntity（formData，HTTP.UTF_8））；
}
httpResponse=httpClient.execute（httpPost）；
}else if（方法==GET）{
if（formData！=null）{
String paramString=URLEncodedUtils.format（formData，“utf-8”）；
url+=“？”+参数字符串；
}
HttpGet HttpGet=新的HttpGet（url）；
httpResponse=httpClient.execute（httpGet）；
}
status_code=httpResponse.getStatusLine（）.getStatusCode（）；
httpEntity=httpResponse.getEntity（）；
Log.i（“登录后的状态代码”，“>>状态代码>>”+状态代码+“>>url>>”+url）；
如果（状态代码==200）
response=EntityUtils.toString（httpEntity）；
其他的
response=“fail”；

DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.setCookieStore(new BasicCookieStore());
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID<<or your variable name>>", <<ACTUAL VALUE>>);
cookie.setDomain(<<SET YOUR DOMAIN NAME HERE>>);
cookie.setPath("/");
httpClient.getCookieStore().addCookie(cookie);
HttpEntity httpEntity = null;
HttpResponse httpResponse = null;
// Checking http request method type
if (method == POST) {
    HttpPost httpPost = new HttpPost(url);
    httpPost.setHeader("Accept", "application/json"); //use text/plain if response if HTTP response is plain text
    httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");                
    if (formData != null) {
        httpPost.setEntity(new UrlEncodedFormEntity(formData, HTTP.UTF_8));
    }
    httpResponse = httpClient.execute(httpPost);
} else if (method == GET) {
    if (formData != null) {
        String paramString = URLEncodedUtils.format(formData, "utf-8");
        url += "?" + paramString;
    }
    HttpGet httpGet = new HttpGet(url);
    httpResponse = httpClient.execute(httpGet);
}

status_code = httpResponse.getStatusLine().getStatusCode();
httpEntity = httpResponse.getEntity();
Log.i("Status Code After Login", "> >status code > >" + status_code + "> >url > >"+url);
if(status_code==200)
    response = EntityUtils.toString(httpEntity);
else
    response="fail";

<<response will contain the final HTTP response>>
