我正在使用电子邮件和密码注册，如果电子邮件和域退出了，则可以正常工作，但是如果[email protected]喜欢传递电子邮件，则它返回html，而我的应用程序崩溃了，因此如何处理此内容

public String webregister(String url, String u, String p) 
    {

        // Create a new httpclient and send post header
        HttpClient httpClient = new DefaultHttpClient();

        // returns true if username and password is valid
        HttpPost httpPost = new HttpPost(url);
        String json = null;
        InputStream is;

        try 
        {
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("username", u));
            nameValuePairs.add(new BasicNameValuePair("password", p));
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));


            // getting the response
            HttpResponse httpResponse = httpClient.execute(httpPost);

            is = httpResponse.getEntity().getContent();

            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;

            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();

        } catch (Exception e) {
            e.printStackTrace();
        }

        return json;

    }

我有自己的问题的解决方案，我尝试了一些方法，对我来说很奏效

            boolean containsHTML=false;

            Pattern htmlPattern = Pattern.compile(".*\\<[^>]+>.*", Pattern.DOTALL);

            containsHTML=htmlPattern.matcher(data).matches();
            if(containsHTML)
            {   

                \\ not parsing or set message : invalid data

            }
            else
            {
                 \\ do jsonparsing here
            }
