Recommended a protobuf LUA version of the previous Project client Lua, communication protocol is PROTOBUF, with NetEase Proto-gen-lua, the use of the process encountered some problems need to be around, such as:1, each change, add proto to generate new files, code scale explosion2, because Lua itself, each file maximum file within the global local variable can not exceed 200, so when the proto scale is too

Protobuf (quickStart), protobufquickstart1. Introduction Protocol Buffers is a data description language developed by Google. It serializes data and can be used in data storage and communication protocols. It can be understood as faster, simpler, and smaller JSON or XML. The difference is that Protocol Buffers is in binary format, while JSON and XML are in text format. Compared with XML, Protocol Buffers has the following advantages: 1. Concise 2. sma

because Protobuf's serialization efficiency and size are very good, so it is used more and more in network communication, and Webosocket also with the web3.0 application more and more extensive, and the two together will slowly form a trend; I was to test a self-written C # WebSocket, so in the web above the combination of PB also wrote a JS instance:1. First download protobuf.js2. Introduction of PROTOBUF Related JS file3. Create a Proto file650) thi

Project useful to Protobuf for cross-platform communication, I also want to write a demo learning practice, so there is this article. * This demo is based on Java development. 1. System environment Windows 2. Required software and Lib 1). Protoc.exe 2). Protobuf-java-2.4.1.jar 3.demo Introduction Very simple program, based on Java development. The function is that the client sends "messages" (cell phone

Recently the company project has buried point of demand, using the Protocolbuffer data format, so to study the use of Protobuf, in this record 1. What is Protocolbuffer? Protocol buffer is a Google Open source project that is a flexible, efficient, and automated way to serialize structured data, such as XML, but it is smaller, faster, and simpler than XML. You can define your own data structure, and then use the code generated by the code generator to

Recently to learn Protobuf's protocol generation, you need to download its code from the Web, download it from this SVN address: Http://protobuf.googlecode.com/svn/trunk After the download is complete, you can find the VC2008 project file in the Protobuf\vsprojects directory, and then open the project for conversion, this is no problem. However, there are two problems in the compilation process, the first of which is as follows: 1>------Build Started:

This article is a follow-up to this article (https://www.cnblogs.com/Binhua-Liu/p/5577622.html), This article describes the protobuf of adding a layer of headers from the PROTOBUF in the Netty framework can only have a limited object. In Mushroom Street open source TEAMtalk, also added a header, according to the type of operation in the header, the corresponding logical processing operation.Here is our conf

In addition to the default JSON and XML serializers, it is possible to use other formats (such as binary) serializers. such as the famous Protobuf and Msgpack, they are binary serializers, characterized by fast speed, small size. Use the following method. 1. Define Mediatypeformatter, here to define the Msgpack formatter as an example, the main code is as follows. Registered in 2.WebApiConfig, the code is as follows. 3. Client calls (Specify accept

Based on the HTTP/2 standard design, GRPC provides features such as bidirectional stream control, traffic control, header compression, and multi-reuse requests on a single TCP connection. These features make mobile devices better able to save power and space.

Differences between java files generated by using modifiers repeated, required, and optional in protobuf's original configuration file. proto Recently, I am working on a Netty-based framework project. This project uses Google's Protobuf as the codec framework. (XML or json is not used to improve efficiency ). After a period of time, I made a simple summary of the original Protobuf files. Here I will mainly

Protobuf officially supports C ++ Java and python, and others are supported by third parties. Two official as3 versions are recommended: Action Script:Http://code.google.com/p/protobuf-actionscript3/ Action Script:Https://code.google.com/p/protoc-gen-as3/ We are very grateful to the two authors for their contributions and expressed their feelings for improvement.
