Java Server重定向次数过多。需要帮助定位新的URL

Question

我正在开发连接到okcupid.com并使用有效用户名和密码登录的应用程序。在测试期间，我让它运行得很好，但是最近okc服务器端肯定发生了一些变化，因为我得到了一个错误，它说服务器重定向了太多次(2) (参见下面的错误输出)。

直到最近，使用(http://www.okcupid.com/locquery?func=query&query=" + zip)的代码，我仍然可以获得输出，如果我转到这个网址或使用代码，学习循环张贴在下面，但我的应用程序，与一个帐户登录停止工作。我觉得饼干有点变了。大多数错误信息都会返回到位置ID。有人能解释一下如何使用Chrome或Firefox在通过浏览器登录到okc时精确定位这个URL，这样我就可以对代码进行修改了吗？提前谢谢。

Answer 1

要获取值的URL似乎缺少func关键字。

例如，下面的URL有效：

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

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

如下所示：

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

{"query" : ""}

主要检查您的代理设置是否有任何更改。下面的程序与适当的代理设置一起工作。

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();
    }
}
