【转】protobuffer php使用

收藏一篇文章 没有实际操作过 . 公司再用都是直接用现成的东西 这片文章收藏一下
protobuffer是google推出的一种数据传的方式,具体压缩,体积小的特点

protobuffer本身不支持php,若要把.proto文件转化为php支持的文件,需要使用第三方的程序

allegro/php-protobuf 或 drslump/Protobuf-PHP

参考 http://yueqian.sinaapp.com/a/52.html

http://hello1010.com/php-protobuf

使用drslump/Protobuf-PHP

一.下载并安装protoc编译器

tar -xzf protobuf-2.4.1.tar.gz && cd protobuf-2.4.1 
cd protobuf-2.1.0 
./configure --prefix=/usr/local/proto 
make 
make check 
make install

二.下载并安装protoc对应的php扩展

https://github.com/chobie/php-protocolbuffers

wget --no-check-certificate  https://github.com/chobie/php-protocolbuffers/archive/master.zip

unzip master && cd php-protocolbuffers-master/

/usr/local/php5/bin/phpize

./configure --with-php-config=/usr/local/php5/bin/php-config

make && make install 

 

重启php

kill -USR2 `cat /usr/local/php5/var/run/php-fpm.pid`

生成的.so文件是protocolbuffers.so  

allegro/php-protobuf 本身就带扩展,同时支持将.proto文件转为php文件

生成的.so文件是protobuf.so

三.下载 drslump/Protobuf-PHP 得到protoc-gen-php插件

并执行

/usr/local/php5/bin/pear channel-discover pear.pollinimini.net
/usr/local/php5/bin/pear install drslump/Protobuf-beta

四.将.proto文件转为php文件

/usr/local/proto/bin/protoc     --plugin=protoc-gen-php='/home/source/Protobuf-PHP-master/protoc-gen-php.php'     --proto_path='/home/source/Protobuf-PHP-master'     --php_out=':./'     '/home/source/Protobuf-PHP-master/test.proto'

执行后报错

PHP Warning:  Declaration of google\protobuf\DescriptorProto::clearExtension() should be compatible with DrSlump\Protobuf\Message::clearExtension($extname) in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Compiler/protos/descriptor.pb.php on line 688

--php_out: protoc-gen-php: Plugin output is unparseable.

类中的方法重复了,注释掉它就行

PHP Warning: Missing argument 1 for DrSlump\Protobuf\Message::hasExtension(), called in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Compiler/PhpGenerator.php on line 280 and defined in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Message.php on line 283
PHP Notice: Undefined variable: extname in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Message.php on line 285
PHP Warning: Missing argument 1 for DrSlump\Protobuf\Message::hasExtension(), called in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Compiler/PhpGenerator.php on line 87 and defined in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Message.php on line 283
PHP Notice: Undefined variable: extname in /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Message.php on line 285
--php_out: protoc-gen-php: Plugin output is unparseable.
library/DrSlump/Protobuf/Compiler/PhpGenerator.php 

87行

if ($proto->hasExtension()) {

改为

if ($proto->hasExtension(null)) {

280行

 if ($msg->hasExtension()) {

改为

 if ($msg->hasExtension(null)) {
vi /home/source/Protobuf-PHP-master/library/DrSlump/Protobuf/Compiler/Cli.php

第二行添加

set_include_path('.:/usr/local/php5/share/pear/');

可执行文件了

使用allegro/php-protobuf 貌似这是个protoc的php客户端

wget https://github.com/allegro/php-protobuf/archive/master.zip

unzip master.zip && cd php-protobuf-master

/usr/local/php5/bin/phpize

./configure --with-php-config=/usr/local/php5/bin/php-config

make && make install 

重启php

kill -USR2 `cat /usr/local/php5/var/run/php-fpm.pid`

使用方法

/usr/local/php5/bin/php  /home/source/aa/ab/cd/php-protobuf-master/protoc-php.php -t .  test2.proto

注意一定要加上 -t 表示输入文件的路径,不然没有文件被输出

例子:

vi test2.proto
message PhoneNumber {
    required string number = 1;
    required int32 type = 2;
}

message Person {
    required string name = 1;
    required int32 id = 2;
    optional string email = 3;
    repeated PhoneNumber phone = 4;
    optional double money = 5;
}

message AddressBook {
    repeated Person person = 1;
}

 

 

生成proto对应的php文件

/usr/local/php5/bin/php  /home/source/aa/ab/cd/php-protobuf-master/protoc-php.php -t .  test2.proto

 /usr/local/php/bin/php -c /usr/local/php/lib/php.ini  /home/source/php-7.0.2/ext/protobuf/protoc-php.php -t .  test_3.proto

vi example_2.php
<?php
require_once 'pb_proto_test2.php';

$foo = new Person();
$foo->setName('abc');
$foo->setId(1);
$foo->setEmail('abc');
$foo->setMoney(321321.32);

$phone_num = new PhoneNumber();
$phone_num->setNumber('16589875625');
$phone_num->setType(3);

$foo->appendPhone($phone_num);
//$foo->appendPhone(2);
$packed = $foo->serializeToString();
//echo $packed;exit;
#$foo->clear();
echo "-----------src------------\n";
echo $foo->getName() ."\n";
echo $foo->getPhone()[0]->getNumber() ."\n";
$foo->dump();
echo "------------------------\n\n\n";


try {
      $p = new Person();
      $p->parseFromString($packed);
      echo "------------parsed-------\n";
      echo $p->getName() ."\n";
      echo $p->getEmail() ."\n";
      echo $p->getMoney() ."\n";
      echo $p->getId() . "\n";
      echo $p->getPhone()[0]->getNumber() ."\n";

      //$p->dump();
      echo "------------------------\n";
      //print_r($xiao);
      } catch (Exception $ex) {
      die('Upss.. there is a bug in this example');
}

执行php文件

/usr/local/php5/bin/php example_2.php
