HttpLibrary

HTTP connection library which is based on OkHttp 3.4.2 library

• This library uses OkHttp as main core, to provide unified interface for using Okhttp's capabilities
• Support Response data as JSONObject, JSONArray, or String. (You don't need to parse response data by your self!)

Gradle build

build.gradle

buildscript {
		repositories {
			...
			jcenter()
		}
	}

dependencies {
  ...
  compile 'com.danielworld:http-connection-library:1.1.7'
  // If current project is dependent on parent project (Indeed, there is parent project)
  // You should write jcenter() in parent's repositories
}

Asynchronous GET

Excute on the main thread!

HttpRequest request = new HttpRequest();
request.setURL("url");                            // Set URL
request.setMethod(HttpRequest.Method.GET);        // Http GET method
request.setRequestType(RequestType.Type.STRING);  // String request type

request.addHeader("header_key", "header_value");  // add Header

request.addParameter("Locale", "enUS");           // add Parameter
request.addParameter("Id", 134);

// Start Async Http connection 
AsyncHttpConnection
  .getInstance()
    .start(request, new JsonHttpResponseHandler(), new okhttp3.Intercepter);

JsonHttpResponseHandler

public void onSuccess(int statusCode, Headers headers, JSONObject response) {
	    // JSONObject response (there should be contents)
}

public void onSuccess(int statusCode, Headers headers, JSONArray response) {
        // JSONArray response (there should be contents)
}

public void onSuccess(int statusCode, Headers headers, String response) {
        // String response (it could be empty)
}

public void onFailure(int statusCode, Headers headers, String response) {
        // Failure response
}

AsyncHttpResponseHandler

public void onSuccess(int statusCode, Headers headers, String response) {
        
}

public void onFailure(int statusCode, Headers headers, String response) {

Add Logger (To track Http/Https traffics)

build.gradle

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    // Daniel (2016-11-04 11:14:02): Okhttp3 logging interceptor
    compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
}

example

public class ExampleApplication extends android.app.Application {
	public void onCreate() {
		/**
			Once you added logger, no need to add logger again when you call other http/https calls 

			But make sure not to add other interceptor in different http/https calls
		*/
		HttpRequest request = new HttpRequest();
		try {
			request.setURL(BapulCubeUrl.ME.toString());
			request.setMethod(HttpRequest.Method.GET);
			request.setRequestType(RequestType.Type.STRING);
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
		HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
		logging.setLevel(HttpLoggingInterceptor.Level.BASIC);

		AsyncHttpConnection.getInstance()
				.start(request, new JsonHttpResponseHandler(), logging);
