android - 如何在 android 中使用 HttpUrlConnection 类将 cookie 添加到 url？

Question

我正在尝试从 url 解析 json 数据，当我尝试创建连接时，它会抛出异常java.net.ProtocolException:读取响应后无法写入请求正文

我收到的响应消息是未找到。

我在网络浏览器中检查了 url，当我使用我的凭据登录时，它显示了 Json 数据。

所以，我发现我需要将 cookie 添加到我的连接中，但我不知道该怎么做。

    public void parseData(String cookie){
    HttpUrlConnection connection;

    try{
    URL url = new URL(params[0]);
                    connection = (HttpURLConnection) url.openConnection();

                    connection.setRequestProperty("Cookie", cookie);
                    Log.e(TAG, "cookie " + cookie);

                    connection.setDoOutput(true);
                    connection.setDoInput(true);
                    connection.setRequestMethod("GET");

                    connection.connect();
Log.e(TAG,connection.getResponseMessage());

    /**
    here i'm trying to parse the data 
    using BufferedReader calss
    **/

    }
    catch(IOException e){}
    }

我需要在连接中添加 cookie。请帮我解决这个问题。

根据 this link 你可以这样做:

Values must be set prior to calling the connect method:

URL myUrl = new URL("http://www.hccp.org/cookieTest.jsp"); 
URLConnection urlConn = myUrl.openConnection(); 

Create a cookie string:

String myCookie = "userId=igbrown";

Add the cookie to a request: Using the setRequestProperty(String name, String value); method, we will add a property named "Cookie", passing the cookie string created in the previous step as the property value.

urlConn.setRequestProperty("Cookie", myCookie); 

Send the cookie to the server: To send the cookie, simply call connect() on the URLConnection for which we have added the cookie property:

urlConn.connect()
