我试图在“http://www.my currency.net/service/rates”获取一个json数据,其中包含有效的json数据,因为我确认使用了我的浏览器,但当我尝试获取页面时返回错误500使用HttpUrlConnection。请参阅下面的代码截图;注意:我一直在使用代码从相同的URL获取成功响应,但它突然开始返回内部服务器错误。
public JSONObject MakeHttpRequest(){
尝试{
URL url = new URL("http://www.mycurrency.net/service/rates");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestMethod("GET");
httpCon.connect();
Log.d("cryptox", String.valueOf(httpCon.getResponseCode() + " : " + httpCon.getResponseMessage() + " : "+ httpCon.getErrorStream()));
InputStream inputStream = new BufferedInputStream(httpCon.getInputStream());
//CREATE A BUFFERED READER TO CONVERT THE BYTES inputStream to char BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder sBuilder = new StringBuilder();
String line = null;
jsonString = null;
try{
while((line = reader.readLine()) != null){
sBuilder.append(line).append("\n");
}
jsonString = sBuilder.toString();
jsonObject = new JSONObject(jsonString);
}
catch (IOException ex){
ex.printStackTrace();
}
catch (JSONException ex){
ex.printStackTrace();
}
finally {
inputStream.close();
}
}
catch (MalformedURLException ex){
ex.printStackTrace();
}
catch(ProtocolException ex){
ex.printStackTrace();
}
catch (IOException ex){
ex.printStackTrace();
}
return jsonObject;
}
