Android 如何以纯文本/字符串而不是JSON读取响应

我想阅读这些简单的数字，这是来自HTTP API的响应

我有响应，但我不知道如何在代码中将其转换为字符串。 下面是我尝试但失败的代码

try {
            //Prepare Connection
            myURL = new URL(url);
            myURLConnection = myURL.openConnection();
            myURLConnection.connect();
            //reading response
            reader= new BufferedReader(new InputStreamReader(myURLConnection.getInputStream()));
            while ((response = reader.readLine()) != null)
                //print response
                Toast.makeText(getApplicationContext(),response,Toast.LENGTH_SHORT).show();

            //finally close connection
            reader.close();
        }
        catch (IOException e){
            e.printStackTrace();
            Toast.makeText(getApplicationContext(), ""+e.toString(), Toast.LENGTH_SHORT).show();
        }

您可以使用java http/https URL连接从输入流获取响应

String getText(String url) throws IOException {
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
//add headers to the connection, or check the status if desired..

// handle error response code it occurs
int responseCode = conn.getResponseCode();
InputStream inputStream;
if (200 <= responseCode && responseCode <= 299) {
    inputStream = connection.getInputStream();
} else {
    inputStream = connection.getErrorStream();
}

BufferedReader in = new BufferedReader(
    new InputStreamReader(
        inputStream));

StringBuilder response = new StringBuilder();
String currentLine;

while ((currentLine = in.readLine()) != null) 
    response.append(currentLine);

in.close();

return response.toString();
}

试试这个代码

    private static String readServerResponse(HttpURLConnection connection) {
        // read the output from the server
        String response = null;
        BufferedReader reader = null;
        InputStreamReader inputStreamReader = null;
        try {
            StringBuilder stringBuilder = new StringBuilder();
            InputStream responseStream = connection.getErrorStream();
            if (responseStream == null)  {
                responseStream = connection.getInputStream();
            }

            inputStreamReader = new InputStreamReader(responseStream);
            reader = new BufferedReader(inputStreamReader);

            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line).append('\n');
            }
            response = stringBuilder.toString();
        } catch (Throwable t) {
            Log.i(LOG_TAG, "Could not read connection response from: " + connection.getURL().toString(), t);
        } finally {
            try {
                if (reader != null) {
                    reader.close();
                }
                if (inputStreamReader != null) {
                    inputStreamReader.close();
                }
            } catch (Throwable ignore) {
            }
        }    
        return response;
    }

运行代码时，我会得到android.os.NetworkOnMainThreadException。您需要在线程内调用此方法或使用异步任务进行后台操作。按照下面的链接使用Asynctask。嘿@RaunakPandey，让我知道它是否有效。我最终通过截击成功了：是的，你可以使用网络库进行截击或改装。
