强制 java.net.HttpUrlConnection 到 return GET 响应，不管 Http-Status-Code

Question

我正在使用 HTTP 客户端将 GET 请求发送到 API，即使 HTTP 状态代码包含错误，它也会以正确的 JSON 对象进行响应，例如401.

public String get(String url){
        URL target;
        HttpURLConnection connection;
        int code = 200;
        BufferedReader reader;
        String inputLine;
        String result = null; 

        try {
            target = new URL(url);
        } catch (MalformedURLException ex) {
            return result;
        }

        try {
            connection = (HttpURLConnection)target.openConnection();
            connection.setRequestMethod("GET");
            connection.connect();
            //code = connection.getResponseCode();
            reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            result = "";
            while ((inputLine = reader.readLine()) != null){ 
                result += inputLine;
            }
            reader.close();
        } catch (IOException ex) {
            return "...";
        }

        return result;
}

在这种情况下，抛出 IOException 并且不写入响应。但是，无论 HTTP-Status-Code 和 hande 错误处理如何，我都希望收到响应。我怎样才能做到这一点？

我不相信你可以那个，但是有https://docs.oracle.com/javase/8/docs/api/java/net/HttpURLConnection.html#getErrorStream-- 用于在出现错误的情况下获取负载。

Force java.net.HttpUrlConnection to return GET-response regardless of Http-Status-Code

java
