## php项目中如何使用protobuf

1、官网下载安装最新版protoc： https://github.com/protocolbuffers/protobuf/releases （具体根据自己的操作系统去选择） 

根据pb文件，生成对应的php实现代码 


```
protoc --php_out=./ cls.proto

```

2、 composer.json中引入pb生成好的文件

```
{
    ...此处省略
    "autoload": {
        ...此处省略
        "psr-4": {
            "GPBMetadata\\": "./examples/cls/v20201016/proto/GPBMetadata",
            "Cls\\": "./examples/cls/v20201016/proto/Cls"
        }
    }
}

```

3、 引入google probuf 依赖

```
composer require "google/protobuf"

```


## protoc文件

php protoc 仅支持pb3.0语法


```
syntax = "proto3";

package cls;

message Log
{
    int64 time = 1;
    message Content
    {
        string key = 1;
        string value = 2;
    }
    repeated Content contents= 2;
}

message LogTag
{
    string key       = 1;
    string value     = 2;
}

message LogGroup
{
    repeated Log logs= 1;
    optional string contextFlow = 2;
    optional string filename = 3;
    optional string source = 4;
    repeated LogTag logTags = 5;
}

message LogGroupList
{
    repeated LogGroup logGroupList = 1;
}

```
