grpc之php客户端实现请求golang服务端

grpc之php客户端实现请求golang服务端

1. 安装protoc 登陆网站 https://github.com/protocolbuffers/protobuf/releases，下载最新版. 解压到目录 /home/wms/Downloads/，然后添加环境变量.

unzip -q  protoc-24.3-linux-x86_64.zip
echo  export PATH=$PATH:/home/wms/Downloads/protoc-24.3/bin>>/etc/profile 
source /etc/profile
protoc --version

2. 安装php

    sudo apt-get install -y php8.1-cli php8.1-fpm php-pear php-dev libtool make gcc cmake

3. 安装grpc扩展

    pecl install grpc

4. 安装protobuf扩展

    sudo pecl install protobuf-3.24.0

5. 安装php生成代码插件

    git clone https://github.com/grpc/grpc
    cd grpc
    git submodule update --init
    mkdir -p cmake/build
    cd cmake/build
    cmake ../..
    make protoc grpc_php_plugin
    sudo cp grpc_php_plugin /usr/bin/grpc_php_plugin

6. 新建项目和proto文件 carrier.proto

syntax = "proto3";
//option java_package = "com.colobu.rpctest";
package carrier;
option go_package = "/";
// The greeting service definition.
service Carrier {
  // Sends a greeting
  rpc GetCarrier (CarrierRequest) returns (CarrierMsg) {}
  rpc GetCarriers (CarriersRequest) returns(CarriersReply){}
}
// The request message containing the user's name.
message CarrierRequest {
  string Name = 1;
}
// The response message containing the greetings

message CarriersRequest{
  int64 Page = 1;
  int64 PageSize = 2;
}

message CarriersReply{
  int64 Page = 1;
  int64 PageSize = 2;
  repeated CarrierMsg CarrierInfo = 3;
}
message CarrierMsg{
  int64 Id = 1;
  string Name = 2;
}

7. 生成代码

    sudo protoc --proto_path=protos \
           --php_out=greeter \
           --grpc_out=greeter \
           --plugin=protoc-gen-grpc=/usr/bin/grpc_php_plugin ./protos/greeter.proto

生成文件结构 8. 新建composer.json

{
  "name": "ddd/grpc",
  "description": "description",
  "minimum-stability": "stable",
  "license": "proprietary",
  "authors": [
    {
      "name": "wms",
      "email": "[e-mail]"
    }
  ],
  "require": {
    "grpc/grpc": "^v1.39.0",
    "google/protobuf": "^v3.12.2"
  },
  "autoload": {
    "psr-4": {
      "GPBMetadata\\": "GPBMetadata/",
      "Carrier\\": "Carrier/"
    }
  }
}

composer install

9. 项目根目录新建client.php

<?php
require dirname(__FILE__) . '/vendor/autoload.php';

$client = new Carrier\CarrierClient('192.168.1.12:50051', [
    'credentials' => Grpc\ChannelCredentials::createInsecure(),
]);

$carrierRequest = new Carrier\CarrierRequest();
$carrierRequest->setName("e邮宝");
$meaData = array(
    'accessToken' => array("65794a3163325679546d46745a534936496e647463794973496e426863334e5862334a6b496a6f694d54497a4e445532496e303d")
);

list($reply, $status) = $client->GetCarrier($carrierRequest,$meaData)->wait();
if($status->code === 0){
    print_r($reply->getName());
    print_r($reply->getId());
    print_r($status->code);
    print_r(json_encode($reply));
    print_r(json_encode($status));
}else{
    print_r($status->code);
    print_r($status->details);
}


$carriersRequest = new \Carrier\CarriersRequest();
$carriersRequest->setPage(1);
$carriersRequest->setPageSize(10);
list($reply1, $status1) = $client->GetCarriers($carriersRequest,$meaData)->wait();
if($status->code === 0){
    print_r($reply1->getPage());
    print_r($reply1->getPageSize());
    print_r($reply1->getCarrierInfo()[0]->getName());
    print_r($status1->code);
    print_r(json_encode($reply1));
    print_r(json_encode($status1));
}else{
    print_r($status1->code);
    print_r($status1->details);
}
