PROTOBUF installation and simple test cases based on the Go language

Go to the official website first download PROTOBUF source code

Https://github.com/google/protobuf/releases

You can download the local and upload to the virtual machine first

I chose source code (tar.gz).

Install a dependent package (error may occur if a package is missing)

Yum install-y gcc gcc-c++ autoconf automake Libtool Curl Make g++ Unzip

After decompression, enter the protobuf-3.5.1 directory and run

./autogen.sh command

Execute the./configure command

Make && make install

Detect PROTOBUF is installed successfully?

Protoc-h

Because you want to use the go language, you need to install the appropriate plugin

1. First to the official website to download the plugin source code to Local:

https://github.com/golang/protobuf/releases

Uploading to a virtual machine for decompression

TAR-ZXVF protobuf-1.1.0.tar.gz

2. Renaming

3. MV Protobuf-1.1.0.tar.gz Protobuf

1. What is the value of querying goroot, as mine is:

   Echo $GOROOT

   /usr/local/gohome/go

2. Under the Goroot directory, create the following directory Src/github.com/golang

   Mkdir-p /usr/local/gohome/go/src/github.com/golang

3. Move the Protobuf directory to the $goroot/src/github.com/golang directory

4. Enter $GOROOT/SRC/GITHUB.COM/GOLANG/PROTOBUF

5. Make install

Example:

Create a file manually first Test.proto

Specify version//note Proto3 and Proto2 are somewhat different syntax =  "Proto3";  //package name, Protoc phone type when the go file is generated by package test;// /enum Type the first field must be a 0enum phonetype {    home = 0;      work = 1; }  //Mobile  message Phone {      Phonetype type = 1;         string number  = 2; }  //man  message person {     // The number that follows indicates the identification number      int32 id = 1;      string  name = 2;     //repeated means repeatable      //can have multiple phones      repeated phone phones = 3; }  //Contact Book   message contactbook {     repeated person persons = 1;  }

Execute the following command to generate the appropriate code file

Protoc--go_out=. *.proto

Or

Protoc--go_out=. Test.proto

In the go language, how to use it?

1. First create the test package, and then upload the generated test.pb.go to the test package

2. Writing test Cases

The contents are as follows:

Package Mainimport ("FMT" "Github.com/golang/protobuf/proto" "Io/ioutil" "OS" "xingej-go/xingej-go/xingej-go666/ Protobuf/test ") Func write () {p1: = &test. person{id:1, Name: "Spark",} book: = &test. contactbook{} book. Persons = Append (book. Persons, p1)//encoded data, _: = Proto. Marshal (book)//writes data to file Ioutil. WriteFile ("./pb_test.txt", data, OS.) Modeperm)}func Read () {data, _: = Ioutil. ReadFile ("./pb_test.txt") Book: = &test. contactbook{}//Decode data proto. Unmarshal (data, book) for _, V: = Range book. Persons {fmt. Println (V.id, V.name)}}func main () {write () read ()}
