Question

我正在处理连接到okcupid.com的应用程序，并使用有效的用户名和密码登录。我在测试期间运行正常，但最近在okc服务器端发生了一些变化，因为我收到的错误表明服务器重定向次数过多（2）（参见下面的错误输出）。

直到最近，使用的代码(http://www.okcupid.com/locquery?func=query&query=" + zip)如果我转到此URL或使用下面发布的学习循环的代码，我仍然可以获得输出，但我的应用程序，使用帐户登录停止工作。我认为cookie发生了变化。大多数错误消息都会返回到位置ID。有人可以解释如何使用Chrome或Firefox在通过浏览器登录okc时查明此URL，以便我可以在代码中进行apprpopriate更改吗？提前谢谢。

获取值的网址似乎缺少func个关键字。

例如，以下网址有效：

https://www.okcupid.com/locquery?func=query&query=14850

{"status" : 0, "ZipCode" : "14850", "query" : "14850", "locid" : 4333788, 
"results" : [{"locid" : 4333788, "text" : "Ithaca"}]}

以下没有：

https://www.okcupid.com/locquery?=query&query=14850

{"query" : ""}

主要检查代理设置是否有任何变化。以下程序使用适当的代理设置。

import java.net.*;
import java.io.*;

public class URLReader {
    public static void main(String[] args) throws Exception {

        //Following line needs to be enabled accordingly if you are using proxy
        //If you are enabling proxy, replace proxy.com with your proxy address    
        //System.setProperty("https.proxyHost", "proxy.com");
        //System.setProperty("https.proxyPort", "80");

        URL oracle = 
            new URL("https://www.okcupid.com/locquery?func=query&query=14850");
        BufferedReader in = new BufferedReader(
        new InputStreamReader(oracle.openStream()));

        String inputLine;
        while ((inputLine = in.readLine()) != null)
            System.out.println(inputLine);
        in.close();
    }
}

Java Server重定向次数过多。需要帮助查找新的URL
