Simple AngularJS Binding With Nested Components

This is a simple example of binding between two nested components.

	<html>
	<head>
	</head>
	<body ng-app="app">

	<h1>Html</h1>
	<parent>
	</parent>

	<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.6/angular.min.js"></script>

	<script type="text/javascript">
	var app = angular.module("app", []);
	app.component("parent", {
	template : "<h1>Parent</h1><button ng-click='controller.show()'>Show</button><child></child>",
	controllerAs : "controller",
	binding : {
	data : "="
	},
	controller : [function() {
	var controller = this;

	controller.show = function() {
	alert(JSON.stringify(data));
	};
	}
	]
	});

	app.component("child", {
	template : "<h2>Child</h2><textarea ng-model='controller.model.stuff'></textarea>",
	controllerAs : "controller",
	binding : {
	data : "="
	},
	controller : [function() {
	var controller = this;

	controller.model = {
	stuff : "text"
	};
	data = controller.model;
	}
	]
	});
	</script>
	</body>
	</html>

Servlet Using Google Vision API

A simple servlet with POST getting an image URL and performs a SAFE SEARCH check using Google Vision API.

Note that it doesn't contain authorization. You can do it locally on your machine or run it live at App Engine using it's service account (it does that automatic so you just deploy it).

	package checkpic

	import java.net.URL;
	import java.net.URLDecoder;

	@Override

	URL url = new URL(imageUrl);
	byte[] array = ByteStreams.toByteArray(url.openStream());

	// For full list of available annotations, see http://g.co/cloud/vision/docs
	SafeSearchAnnotation annotation = annotationResponse.getSafeSearchAnnotation();

	}
	}
	}
