Question

我按照Ian Brown的教程为请求http://www.hccp.org/java-net-cookie-how-to.html

设置了一个cookie

但它不起作用：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
public class cookie {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub
    URL myUrl = null;
    try {
        myUrl = new URL("http://server/test.php?hlp");
    } catch (MalformedURLException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    try {
        URLConnection con = myUrl.openConnection();
        con.setRequestProperty("Cookie", "accesstoken=WERT-DES-COOKIES");
        con.connect();
        String line;
        StringBuilder builder = new StringBuilder();
        BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
        while((line = reader.readLine()) != null) {
         builder.append(line);
        }
        System.out.println(builder);

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

php-test-Script返回$ _REQUEST-values ...但我只得到URL中给出的“hlp” - 参数。有人能告诉我什么错了吗？！

您提到您使用$ _REQUEST来检索Cookie。请注意，$_REQUEST将检索仅请求参数作为查询字符串或POST请求传递。要检索cookie，请使用$_COOKIE关联数组。检查this tutorial。

java url连接集cookie
