swagger生成php接口文档

首先要先安装基于laravel5的swagger包

地址：https://github.com/DarkaOnLine/L5-Swagger

一、安装

Laravel	Swagger UI	OpenAPI Spec compatibility	L5-Swagger
5.1.x	2.2	1.1, 1.2, 2.0	php composer require "darkaonline/l5-swagger:~3.0"
5.2.x	2.2	1.1, 1.2, 2.0	php composer require "darkaonline/l5-swagger:~3.0"
5.3.x	2.2	1.1, 1.2, 2.0	php composer require "darkaonline/l5-swagger:~3.0"
5.4.x	2.2	1.1, 1.2, 2.0	php composer require "darkaonline/l5-swagger:~4.0"
5.4.x	3	2.0	php composer require "darkaonline/l5-swagger:5.4.*"
5.5.x	3	2.0, 3.0	php composer require "darkaonline/l5-swagger:5.5.*"
5.6.x	3	2.0, 3.0	php composer require "darkaonline/l5-swagger:5.6.*"

二、

php artisan vendor:publish --provider "L5Swagger\L5SwaggerServiceProvider"

三、Open your AppServiceProvider (located in app/Providers) and add this line in register function

$this->app->register(\L5Swagger\L5SwaggerServiceProvider::class);

or open your config/app.php and add this line in providers section

L5Swagger\L5SwaggerServiceProvider::class,

建立swaggerController控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Swagger\Annotations as SWG;

class SwaggerController extends Controller
{

    public function getJSON()
    {
        // 正式环境(production)访问swagger文档时返回空
        if (config('app.env') == 'production') {
            return response()->json([], 200);
        }

        $swagger = \Swagger\scan(app_path('/'));

        return response()->json($swagger, 200);
    }
}

在routes/web.php下加入如下代码

Route::get('/swagger', function () {
    return view('vendor.l5-swagger.index',['urlToDocs' => '/doc/json']);
});
Route::group(['prefix' => 'doc'], function () {
    Route::get('json', 'SwaggerController@getJSON');
});

通过你的域名/swager可以访问到接口、域名/doc/json访问到的是json

http://*****.com/swagger#/article/article.list  要想显示article.list  则需要添加deepLinking: true

建立BaseController 

<?php

namespace App\Http\Controllers\V1;


use App\Http\Controllers\Controller ;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

class BaseController extends Controller
{
    use AuthenticatesUsers ;



    /**
     * @SWG\Swagger(
     *   host="",
     *   basePath="/api/v1",
     *   @SWG\Info(
     *     title="app",
     *     version="1.0.0"
     *   ),
     * @SWG\SecurityScheme(
     *   securityDefinition="api_key",
     *   type="apiKey",
     *   in="header",
     *   description = "认证token  Bearer+空格+token",
     *   name="Authorization"
     * ),
     * )
     */
    public function __construct()
    {

    }

}

这样基本swagger文档就搭建成功了

每个接口编写 swagger 格式的注释会有很多种、下面举几个例子

Get请求

    /**
     * @SWG\Get(
     *      path="/article/list",
     *      tags={"article"},
     *      operationId="article.list",
     *      summary="获取知识库列表(分页)",
     *      consumes={"application/json"},
     *      produces={"application/json"},
     *      security={{"api_key": {"scope"}}},
     *      @SWG\Parameter(in="query",name="page",description="页码",required=false,type="integer",),
     *      @SWG\Parameter(in="query",name="title",description="知识库标题",required=false,type="string",),
     *      @SWG\Parameter(in="query",name="type_id",description="类型id",required=false,type="integer",),
     *      @SWG\Parameter(in="query",name="pid",description="产品编号",required=false,type="string",),
     *      @SWG\Response(
     *          response=200,
     *          description="",
     *          @SWG\Schema(
     *              type="object",
     *              @SWG\Property(property="code", type="string",description="状态码"),
     *              @SWG\Property(property="message", type="string",description="提示信息"),
     *              @SWG\Property(property="data", type="object",
     *                  @SWG\Property(property="current_page", type="string", description="现在的页码"),
     *                  @SWG\Property(property="first_page_url", type="string", description="第一页URL"),
     *                  @SWG\Property(property="from", type="integer", description="开始"),
     *                  @SWG\Property(property="last_page", type="string", description="最后一页页码"),
     *                  @SWG\Property(property="last_page_url", type="string", description="最后一页url"),
     *                  @SWG\Property(property="next_page_url", type="integer", description="下一页url"),
     *                  @SWG\Property(property="path", type="string",description="路径"),
     *                  @SWG\Property(property="per_page", type="integer", description="每页显示数量"),
     *                  @SWG\Property(property="prev_page_url", type="string",description="上一页地址"),
     *                  @SWG\Property(property="to", type="integer", description="结束"),
     *                  @SWG\Property(property="total", type="integer", description="总条数"),
     *                  @SWG\Property(property="lists", type="array",
     *                      @SWG\Items(type="object",
     *                          @SWG\Property(property="aid", type="string",description="知识库编号"),
     *                          @SWG\Property(property="title", type="string",description="标题"),
     *                          @SWG\Property(property="content", type="string",description="内容"),
     *                          @SWG\Property(property="created_at", type="string",description="创建时间"),
     *                          @SWG\Property(property="views", type="integer",description="浏览数量"),
     *                          @SWG\Property(property="product_name", type="string",description="产品名称"),
     *                          @SWG\Property(property="type_name", type="string",description="类型名称"),
     *                      ),
     *                  ),
     *              ),
     *          )
     *      ),
     * )
     */

get请求效果如下：

Post请求 

    /**
     * @SWG\Post(
     *      path="/article/create",
     *      tags={"article"},
     *      operationId="create_article",
     *      summary="创建知识库",
     *      consumes={"application/json"},
     *      produces={"application/json"},
     *      security={{"api_key": {"scope"}}},
     *      @SWG\Parameter(
     *          in="body",
     *          name="data",
     *          description="",
     *          required=true,
     *          @SWG\Schema(
     *              type="object",
     *              @SWG\Property(property="pid",description="产品编号",type="string"),
     *              @SWG\Property(property="uids",type="array",
     *                  @SWG\Items(type="integer",description="成员编号"),
     *              ),
     *          )
     *      ),
     *      @SWG\Response(
     *          response=200,
     *          description="",
     *          @SWG\Schema(
     *              type="object",
     *              @SWG\Property(property="code", type="string",description="状态码"),
     *              @SWG\Property(property="message", type="string",description="提示信息"),
     *          )
     *      ),
     * )
     */

post请求效果如下：
