URL没有与主机名关联的地址

问题描述

我有一个Web服务调用打倒一个JSON对象,如果我的IP地址,而不是主机名它仅适用。我一直罚款使用IP地址,但现在我需要有主机名。

I have an web service call to bring down a JSON object and it only works if I have the IP address and not the host name. I have been fine using IP addresses but now I need to have the host name.

下面是我的code

    StringBuilder stringBuilder = new StringBuilder();
    HttpParams httpParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(httpParams, 3000);
    HttpConnectionParams.setSoTimeout(httpParams, 7000);
    DefaultHttpClient httpClient = new DefaultHttpClient(httpParams);
    HttpPost httpost = new HttpPost(URL);
    try {
        HashMap<String,String>  params = new HashMap<String,String>();
        // Login info
        params.put("username", edtUserName.getText().toString());
        params.put("password", edtPass.getText().toString());
        params.put("deviceOS", "Android");
        params.put("deviceOSVersion", android.os.Build.VERSION.RELEASE);
        params.put("language", "0");
        //JSON object holding the login info
        JSONObject holder = new JSONObject(params);

        StringEntity se = new StringEntity(holder.toString());

        httpost.setEntity(se);

        httpost.setHeader("Content-Type", "application/json");
        //Executing the call
        HttpResponse response = httpClient.execute(httpost);
        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        if (statusCode == 200) {
            HttpEntity entity = response.getEntity();
            InputStream inputStream = entity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }
            inputStream.close();
        } else {
            returnCode = -1;
            Log.d("JSON", "Failed to download file");
        }
    } catch (Exception e) {
        returnCode = -1;
        Log.d("readJSONFeed", e.getLocalizedMessage());
    }

    return stringBuilder.toString();

我不知道为什么不起作用。我有WIFI连接在手机上测试,我的清单有&LT;使用许可权的android:NAME =android.permission.INTERNET对/&GT; &LT;使用许可权的android:NAME =android.permission.ACCESS_NETWORK_STATE/&GT;

本网站服务不工作。只是没有在Android

This web service does work. Just not on Android

如果任何人有一个想法,将是巨大的,谢谢你。

If anyone has an idea that would be great, Thanks.

推荐答案

我通过删除这些行固定它

I fixed it by removing these lines

HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 3000);
HttpConnectionParams.setSoTimeout(httpParams, 7000);
DefaultHttpClient httpClient = new DefaultHttpClient(httpParams);

而与此code替换它。

And replacing it with this code

HttpClient httpClient = MainActivity.createHttpClient();


public static HttpClient createHttpClient(){
    try {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(null, null);

        SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 15000);
        HttpConnectionParams.setSoTimeout(params, 5000);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", sf, 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        return new DefaultHttpClient(ccm, params);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}
