Composer是php的包管理工具，可以快速安装、卸载、更新、搜索、依赖等。
一. 准备工作
创建项目目录和Composer包目录
首先需要创建两个空的文件夹,分别来当做项目根目录和composer包目录
1
2
3
| .
├── test-package
└── test-project
|
二. Composer包目录
2.1 初始化Composer包
1
2
| cd test-package
composer init
|
按照提示输入相关信息，比如包名、版本号、作者、描述等。
这个时候的composer.json文件内容如下：
1
2
3
4
5
6

8
9
10

| {
"name": "hanpy/uc-client",
"description": "test user center http client",
"authors": [
{
"name": "hanpy",
"email": "hanpengyu521@126.com"
}
],
"require": {},
"autoload": {
"psr-4": {
"hanpy\\": "src/"
}
}
}
|
2.2 在包目录下面创建src目录
1
2
| mkdir src
touch src/UserCenterClient.php
|
src/UserCenterClient.php 文件的内容

| <?php
namespace hanpy;
class UserCenterClient
{
public function home()
{
return 'uc hello world!';
}
}
|
这个时候的目录结构

├── LICENSE
├── autoload_classmap.php
├── autoload_namespaces.php
├── autoload_psr4.php
├── autoload_real.php
└── autoload_static.php
|
三. 项目目录
3.1 添加依赖包以及修改repository
