android send https post request to the server with

问题:

In my app is used send request by https by following this source answer. Now some of them apache methods deprecated. Can anyone help me in order solve in a new approach?

回答1:

To avoid using deprecated methods in API connectivity, think about using Retrofit. It's a third party library which makes HTTP communication much simpler.

When using Retrofit, you can create an interface of an API endpoint and the use it like a method. The rest of the HTTP request is managed by the library.

Here is the link to the Retrofit github homepage: http://square.github.io/retrofit/

HttpURLConnection is part of SDK from API 1, you can use same http://developer.android.com/reference/java/net/HttpURLConnection.html.

// HTTP POST request
private void sendPost() throws Exception {

    //Your server URL
    String url = "https://selfsolve.apple.com/wcResults.do";
    URL obj = new URL(url);
    HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

    //add reuqest header
    con.setRequestMethod("POST");
    con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");

    //Request Parameters you want to send
    String urlParameters = "sn=C02G8416DRJM&cn=&locale=&caller=&num=12345";

    // Send post request
    con.setDoOutput(true);// Should be part of code only for .Net web-services else no need for PHP
    DataOutputStream wr = new DataOutputStream(con.getOutputStream());
    wr.writeBytes(urlParameters);
    wr.flush();
    wr.close();

    int responseCode = con.getResponseCode();
    System.out.println("\nSending 'POST' request to URL : " + url);
    System.out.println("Post parameters : " + urlParameters);
    System.out.println("Response Code : " + responseCode);

    BufferedReader in = new BufferedReader(
            new InputStreamReader(con.getInputStream()));
    String inputLine;
    StringBuffer response = new StringBuffer();

    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();

    //print result
    System.out.println(response.toString());

}

Please check the below function:

  public String makeServiceCall(String url1, MultipartEntity reqEntity) {
    try {
        // http client
        URL url= new URL(url1);
        HttpURLConnection httpClient = (HttpURLConnection) url.openConnection();
        httpClient.setRequestMethod("POST");
        httpClient.setUseCaches(false);
        httpClient.setDoInput(true);
        httpClient.setDoOutput(true);
        httpClient.setRequestProperty("Connection", "Keep-Alive");
        httpClient.addRequestProperty("Content-length", reqEntity.getContentLength()+"");


         OutputStream os = httpClient.getOutputStream();
         reqEntity.writeTo(httpClient.getOutputStream());
         os.close();
         httpClient.connect();

         if (httpClient.getResponseCode() == HttpURLConnection.HTTP_OK) {
             return readStream(httpClient.getInputStream());
         }


    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return null;
}

In Android SDK 23

HttpClient is deprecated, you can migrate your code in HttpURLConnection

Something like this

URL url = new URL(urlString);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.connect();

if u want to continue using HttpClient for API level 22 and 23.. add org.apache.http.legacy.jar in ur project's Lib folder, ull get .jar file in Android\sdk\platforms\android-23\optional..

if ur using android studio, after copy pasting jar file in lib folder,right click on jar file and click add as library

ur problem will be solved..comment if need any help. thanx!

You can Use this Method for Get or Post Any purpose. Just use this method for Server request.

public void RequestToServer() {
        //  String User_id = "h";
        AsyncHttpClient client = new AsyncHttpClient();
        RequestParams params = new RequestParams();
        // params.put("uid", User_id.toString());
        client.post("http:// Your Url", params, new AsyncHttpResponseHandler() {

            @Override
            public void onSuccess(String s) {
                super.onSuccess(s);
                Log.d("Server Response for success :", s);
                tv.append("service_ReloadSqlDB" + "    " + s);
            }

            @Override
            public void onFailure(Throwable throwable) {
                super.onFailure(throwable);
                Log.d("Server Response for onFailure ", throwable.toString());
            }
        });

    }

You also need a jar file = android-async-http-1.3.1.jar download this jar and add your android project in libs folder After that add this in your build.gradle

dependencies {

compile files('libs/<android-async-http-1.3.1.jar>')
}

Finally rebuild your project , run the application , Get your Server response.
