为什么java.net.HttpURLConnection响应了身份不明的角色？

Question

我的请求执行程序类将未识别的字符作为响应。请帮我理清这个

import java.net.HttpURLConnection;

        connection = (HttpURLConnection) neturl.openConnection();
        connection.setRequestMethod("GET");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Accept-Charset", "UTF-8");//ADDED

===这里我做了一些补充和补充;逻辑==

        statusCode = connection.getResponseCode();

===这里我做了一些补充和补充; logics.response代码 200 但响应文本未正确显示==

        if ((statusCode == 200) || (statusCode == 201) || (statusCode == 302)) {

           is = connection.getInputStream();
        }
        else {
            is = connection.getErrorStream();
        }

        BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));

        String output;
        while ((output = br.readLine()) != null) {
            retStr += output;
        }

这是我的回复[retStr]

我认为你在这里输出gzip流作为输出..尝试下面的代码中的东西。

当您拨打https网址时，您会收到HttpsURLConnection作为回复，而不会处理gzip stream，请尝试以下网址。

HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Accept-Encoding", "gzip");
...
InputStream inStream = new GZIPInputStream(conn.getInputStream());
