用composer裝oauth2-server-php v0.9(bshaffer)

從官網下載composer

https://getcomposer.org/

composer是跨平臺的, 這里只介紹windows使用composer

下載好了后, 進行安裝.

可以選擇 "Install Shell Menus", 這將會在右鍵菜單里面增加composer的快捷入口.

composer會自動找到php.exe的位置. 也可以自定義php的位置.

下載composer.phar

該死的"墻", 連接上×××.

我的php 5.3.3 確實夠老的. 點擊next.

成功, composer設置了 path 環境變量. 所以可以在command line的任意位置使用composer命令了.

下面就來用一下composer.

新建一個文件夾, C:\clearvale\elgg\ztest\oauth_server_bshaffer

由于裝了  shell menu,

所以直接在文件夾上右鍵選擇 Use Composer here

現在遵循最傳統的方式使用composer, 新建oauth_server_bshaffer/composer.json 文件.

這里用 bshaffer的oauth3 server來演示. 在composer.php里面寫入如下內容.

{

    "require": {

        "bshaffer/oauth3-server-php": "~0.9"

    }

}

<<<<<<<<<<<<<<<<<<<<

這里記錄一下, 之前寫入的是 

{

    "require": {

        "bshaffer/oauth3-server-php": "~1.7",

    }

}

首先多了個 , 號

導致composer報錯.

C:\clearvale\elgg\ztest\oauth_server_bshaffer>composer install

  [Seld\JsonLint\ParsingException]

  "./composer.json" does not contain valid JSON

  Parse error on line 3:

}

  ---------------------^

  Expected: 'STRING' - It appears you have an extra trailing comma

install [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--no-plugins] [--no-custom-installers] [--no-autoloader] [--no-scripts] [--n

o-progress] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [--ignore-platform-reqs] [packages1] ... [packagesN]

去掉逗號后, 又報如下錯誤:

C:\clearvale\elgg\ztest\oauth_server_bshaffer>composer install

大意是說: 1.7這個版本的最低php環境是 php >= 5.3.9

那么到底有多少個版本, 哪個版本支持php5.3.3 呢?

可以訪問composer的packagelist官網.

https://packagist.org/packages/bshaffer/oauth3-server-php#v0.9

正好, bshaffer也推薦v0.9為stable release. 

>>>>>>>>>>>>>>>>>>>>>>>>>

所以就裝 v0.9, 繼續composer install

C:\clearvale\elgg\ztest\oauth_server_bshaffer>composer install

Loading composer repositories with package information

Installing dependencies (including require-dev)

  - Installing bshaffer/oauth3-server-php (v0.9)

    Downloading: 100%

Writing lock file

Generating autoload files

成功了. composer已經成功安裝了oauth3-server-php (v0.9),

查看安裝后的文件目錄.

composer.lock用于鎖定所有包的版本.  安裝的時候會檢查composer.lock文件的存在.

composer.lock和composer.json一起控制項目的版本.

比如現在已經裝完了包, 再次運行composer install, 會顯示 Nothing to install or update.

oauth_server_php v0.9包已經安裝完畢.

下面測試一下 auto_load

新建: C:\clearvale\elgg\ztest\oauth_server_bshaffer\test.php

寫入如下內容:

<?php
require 'vendor/autoload.php';
//token controller
$dsn = "mysql:my_oauth3_db;host=localhost";
$username = "root";
$password = "root";
$storage = new OAuth3_Storage_Pdo(array('dsn' => $dsn, 'username' => $username, 'password' => $password));
print_r($storage);

最后打印出了 $storage對象.

那么可見包里面的文件已經被自動加載. 只需要 require 'vendor/autoload.php';

包里面的所有文件都可以使用了.
