api 设计 多api一起访问

查看了下别的api的返回示例 我选出这样的返回样式
{
“resultcode”:”200”,
“reason”:”Successed!”,
“result”:{
“count”: 11,
“commentlist”: []
},
“notice”….
}
当前api访问的错误和原因加 非当前api的处理（比如notice 通知 注:来自开源中国ios版本的代码理解 他每个api都有可能有notice节点） 都跟result同级

很多时候（特别是app刚刚启动）经常会同时发起好几个api请求 于是乎我就想 能不能几个api同时请求呢我就使用php来做了个测试结果是可以做到的

<?php

use Think\Controller;

use Home\Action\Article;

class IndexController extends Controller {
    protected $response_data = array ();
    protected function response() {
        if (count ( $this->response_data ) > 0) {
            switch ($this->dtype) {
                case "xml" :
                    exit ( xml_encode ( $this->response_data ) );
                    break;
                default :
                    exit ( json_encode ( $this->response_data ) );
                    break;
            }
        }
    }

     public function index() {
        $actions = array();

        switch ($action) {
            case $this->accept_action_article_cover_key :

                $chapter_list = $Chapter->getList( "articleno = " . $articleno );
                $response_data =  $chapter_list;
                break;
            case $this->accept_action_article_list_key :
                $Article = new Article($actionInfo);
                $response_data =   $Article->getlist();
                break;
            case $this->accept_action_chapter_key :
                $Chapter = new Chapter($actionInfo);
                $response_data =  $Chapter->getTxt($articleno, $chapterno);
                break;
            case $this->accept_action_article_key :
                $Article = new Article($actionInfo);
                $response_data =  $Article->getArticle();
                break;
            default :
                break;
        }
        return array($action=>$response_data);
    }
}

1、首先获取操作集合
从代码中可以看出是获取所有请求中的数据
每个key对应json格式的数据
json_decode($action,TRUE); 后面这个参数 是让解析的结果是数组而不是对象

2、然后针对每一个action做处理handleAction 此处处理中 就么法使用 get post来获取参数 了 我使用的是 在构造函数中 把参数传递进去 这样就可以把这个action只跟此处传递来的json有关系
后期可以加上一个user认证的json

此图中专门让小说章节丢失为的是能展示完整

以前的请求方式两个请求分别是
…?action=chapter&chapterno=17110,17111
…?action=article_list
