# Protobuffer极速入门

> Swift & Python demo for staters

## 环境安装

1、推荐使用homebrew安装

```shell

brew install swift-protobuf

```

2、安装python（服务环境）

```shell

brew install python3

```

3、检查python的安装的情况

```

python --version

```

如果打印python版本号说明python已经安装成功，如果出现`\zsh: command not found: python`

```shell

echo "alias python=/usr/bin/python3" >> ~/.zshrc

```

```shell

source ~/.zshrc

```

## 获取协议文件

1、创建一个contact.proto文件

```protobuf

syntax = "proto3";

message Contact {

  enum ContactType {

    SPEAKER = 0;

    ATTENDANT = 1;

    VOLUNTEER = 2;

  }

  string first_name = 1;

  string last_name = 2;

  string twitter_name = 3;

  string email = 4;

  string github_link = 5;

  ContactType type = 6;

  string imageName = 7;

};

message Speakers {

  repeated Contact contacts = 1;

}

```

2、通过命令行生成Python和Swift对应的文件

```shell

protoc --swift_out=. contact.proto

protoc -I=. --python_out=. ./contact.proto

```

这个时候你会看到`contact_pb2.py` 、`contact.pb.swift`两个文件

## 服务端

1、编写一个简单的Python程序，并且将`contact_pb2.py`文件放到后台程序的根目录

2、安装依赖

```

pip install flask

```

3、启动服务

```shell

python3 RWServer.py

```

你将会在控制台看到` Running on http://127.0.0.1:5000`

4、浏览器输入**http://127.0.0.1:5000/currentUser**

```html

```

## 客户端

1、安装 swift-protobuf

客户端需要使用CocoaPod集成苹果官方提供的[swift-protobuf](https://github.com/apple/swift-protobuf)库

```

 pod 'SwiftProtobuf', '~> 1.0'

```

然后pod install

3、将`contact.pb.swift`拖入工程

2、编写一个网络请求

```Swift

import Foundation

class RWService {

    static let shared = RWService()

    let url = "http://127.0.0.1:5000"

    

    private init() { }

  

    func getCurrentUser(_ completion: @escaping (Contact?) -> ()) {

        let path = "/currentUser"

        let url = URL(string: "\(url)\(path)")

        let session = URLSession.shared

        let task = session.dataTask(with: url!) { (data, response, error) in

            if let error = error {

                completion(nil)

                return

            }

            if let data = data {

                let contact = try? Contact(serializedData: data)

                completion(contact)

            }

        }

        task.resume()

    }

}

```

3、调用

```Swift

 RWService.shared.getCurrentUser { contact in

   guard let contact = contact else {

   		return

   }

   print(contact.firstName);

   print(contact.lastName);

   print(contact.email);

}

```
