JarCastingGgaREST
Introduction
This library makes it easy to work with http connections on Android or Java. It's especially designed to work with JSON, as it uses a JSON de/serializer by default. Its strongest points are the following :
- When you make a request (get, post, put, delete) and you register the listeners, your listener code will be code in the main thread. This design allows the modification of UI components directly in the listener code.
- You can specify the object that you are expecting and it will be deserialized using the Jackson library. If it's a list, you also can use the list listener to deserialize it as an object list.
Android Configuration
To use the GgaRest class you only have to call the init method when your application start. Here is an example by adding default headers like an Api key.
GgaRest.init(this);
GgaRest.addDefaulteader("Accept","application/json");
Java Configuration
You not need to init the Library. You can get a Webservice instance directly calling GgaRest.ws()
Usage
This example gets the content of the url given and deserializes the content as an OriginAndUrl object:
GgaRest.ws().get("http://httpbin.org/get")
.onSuccess(OriginAndUrl.class, new OnObjResponseListener<OriginAndUrl>() {
@Override
public void onResponse(int code, OriginAndUrl object, Response fullResponse) {
txtUrl.setText(object.url);
txtIp.setText(object.origin);
}
})
.onOther(new OnResponseListener() {
@Override
public void onResponse(int code, Response fullResponse, Exception exception) {
Toast.makeText(MainActivity.this, "Get failed", Toast.LENGTH_SHORT).show();
}
})
.execute();
Or here we use basic auth to retrieve the commits of this repository:
GgaRest.useBasicAuth(GITHUB_USERNAME,PASSWORD);
GgaRest.ws()
.get("https://api.github.com/repos/greengrowapps/ggarest/commits")
.onSuccess(Commit.class, new OnListResponseListener<Commit>() {
@Override
public void onResponse(int code, List<Commit> object, Response fullResponse) {
populateCommits(object);
}
})
.onResponse(401, new OnResponseListener() {
@Override
public void onResponse(int code, Response fullResponse, Exception exception) {
Toast.makeText(MainActivity.this, "Unauthorized", Toast.LENGTH_SHORT).show();
}
})
.execute();
It's possible to mock some calls for test prouposes:
GgaRest.ws().mockGet("http://mysite/someendpoint/")
.responseCode(200)
.responseContent("{\"text\":\"hello\"}")
.save();
Android Integration
1) Add as a dependency to your build.gradle:
dependencies {
compile 'com.greengrowapps:ggarest:0.16'
}
2) Avoid duplicate files copied in APK adding this inside the android tag in your build.gradle:
packagingOptions {
exclude 'META-INF/ASL2.0'
exclude 'META-INF/LICENSE'
exclude 'META-INF/MANIFEST.MF'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
3) Initialize the object in your application onStart or in one of your activities' onCreate to start using it:
GgaRest.init(this);
Java Integration
Add as a dependency to your build.gradle or pom.xml:
dependencies {
compile 'com.greengrowapps:ggarest-java:0.0.2'
}
<dependency>
<groupId>com.greengrowapps</groupId>
<artifactId>ggarest-java</artifactId>
<version>0.0.2</version>
</dependency>
