Auch mit der JavaScript-Auszeichnungssprache JSON (J ava S cript O bject N otation) tritt Protocol Buffers häufig in den direkten Vergleich, wobei aber zu erwähnen ist, dass beide Technologien mit unterschiedlichen Zielsetzungen designt wurden: JSON ist ein Nachrichtenformat, das aus JavaScript hervorgegangen ist, seine Nachrichten im Textformat austauscht und von praktisch allen gängigen Programmiersprachen unterstützt wird Google verwendet Protokollbuffer in JS (GMail usw.) über ihre Closure-Bibliothek und generiert JS-Code mit einem (leider nicht Open- protoc) modifizierten protoc (es müsste wahrscheinlich vor dem Öffnen auf eine protoc portiert werden) -ourced) Protocol Buffer是个什么东东？.

While JSON is a common modus operandi (especially in JavaScript), using a binary serialization format typically provides an advantage in compression size and performance at the cost of losing human readability of the encoded data. Two common binary serialization formats across many programming languages are Protocol Buffers and Apache Avro. Avro is inherently a bit more compact than Protobuf, whereas Protobuf uses the additional data as field tags that could make it slightly more forgiving. Protocol buffers, or Protobuf, is a binary format created by Google to serialize data between different services. Google made this protocol open source and now it provides support, out of the box, to the most common languages, like JavaScript, Java, C#, Ruby and others Protobuf/Protocol Buffers: Protobuf is a Google's language-neutral, platform-neutral method for deserializing & serializing structured data between 2 services. Protobuf can be used to define the contract for the communication between 2 systems Protocol Buffers (protobuf) ist ein Datenformat zur Serialisierung mit einer Schnittstellen-Beschreibungssprache.

Il est disponible pour la plupart des langages. Une application en Java peut envoyer des objets à une application en Go. Le système repose sur un fichier qui va permettre de structurer notre objet, les fichiers .proto. Ce fichier va un peu comme une interface décrire notre objet. Protobuf permet ensuite.
In this course, Moving Beyond JSON and XML with Protocol Buffers, you will see just how protocol buffers provide a way to enable this communication faster and more efficiently than competing protocols such as XML and JSON. First, you'll see features and practices that are available to allow messages to evolve without breaking older applications. Next, you'll be introduced to the syntax that is.
