Question

这是我的代码：

urlConnection = (HttpURLConnection) url.openConnection();
                urlConnection.setRequestMethod("GET");
                urlConnection.connect();    
                    int status = urlConnection.getResponseCode();
                    // Read the input stream into a String
                    InputStream inputStream = urlConnection.getInputStream();
                    StringBuffer buffer = new StringBuffer();
                    if (inputStream == null) {
                        return;
                    }
                    reader = new BufferedReader(new InputStreamReader(inputStream));

以下是我的JSON示例：

[{"Id":1,"Name":"Алупка","RegionId":1},{"Id":2,"Name":"Алушта","RegionId":1},{"Id":3,"Name":"Армянськ","RegionId":1}]

但urlConnection.getResponseCode()仍会返回“403”。

请告诉我如何解决这个问题！提前谢谢！

Answer 1

当我尝试加载您在问题中提供的URL时，它表示需要HTTPS。使用Firebug，我确认在这种情况下服务器实际上返回403。将协议从http更改为https会按预期返回JSON。因此，在您的代码中，当您创建URL对象时，请确保您指定的URL以https：//而不是http：//

The error could be due to server is rejecting the connection due to you are not sending "User-Agent".

add this line in order to fix it:

connection.addRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0");
