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
namespace Home\Controller;
use Think\Controller;

use Home\Action\Article;
use Home\Action\Chapter;

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();

foreach ( $_GET  as $key => $action ) {
$actions[$key] = $action;
}
foreach ( $_POST  as $key => $action ) {
$actions[$key] = $action;
}
foreach ( $actions  as $key => $action ) {
$action = json_decode($action,TRUE);
$this->addResponseData($key,$action);
}
$this->response();
}
public function addResponseData($key,$action){
$this->response_data[$key] = $this->handleAction($action);
}

/***
* article_cover
* 获取小说的图片
* articleno
*/
protected $accept_action_article_cover_key = "article_cover";
/***
* chapter_list
* 获取小说章节list
* articleno
* page pagesize
*/
protected $accept_action_chapter_list_key = "chapter_list";
/***

* 获取小说list
* page pagesize
*/
protected $accept_action_article_list_key = "article_list";
/***

* 获取某章节的内容
* articleno chapterno(17110  或者 17110,17111)
* dtype txt json xml
*/
protected $accept_action_chapter_key = "chapter";
/***
* article
* 获取小说详情
* articleno
* page pagesize
*/
protected $accept_action_article_key = "article";

public function handleAction($actionInfo){
$action = $actionInfo["action"];
$articleno = $actionInfo["articleno"];
$chapterno = $actionInfo["chapterno"];
switch ($action) {
case $this->accept_action_article_cover_key :
$Article = new Article ($actionInfo);
$response_data =  $Article->ArticleCoverInfo ();
break;
case $this->accept_action_chapter_list_key :
$Chapter = new Chapter($actionInfo);
$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

<?php
namespace Home\Action;
use Home\Action\BaseAction;
class Article extends BaseAction{
protected $articleno;
//protected $file_base = "F:/yixuan_android/WWW/thinkphp_git/Public/article";
protected $file_base = "d:/wwwroot/thinkphp_api/wwwroot/Public/article";
protected $file_image_base = "/image/0/";
public function __construct($info){
parent::__construct($info);
$this->table_name = "article";
$this->articleno = $info["articleno"];
}
public function getArticle($articleno = -1){
if ($articleno != -1) {
$this->articleno = $articleno;
}
return $this->getModel()->find ( $this->articleno );
}
public function ArticleList(){
return $this->getList();
}
public function SaveCover(){
//保存base64字符串为图片
//匹配出图片的格式
$base64_image_content = $_POST["base64_image_content"];
if (preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_image_content, $result)){
$type = $result[2];
$new_file = "./test.{$type}";
if (file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_image_content)))){
echo '新文件保存成功：', $new_file;
}
}
}
public function ArticleCoverInfo(){
$image_file = $this->ArticleCoverFile();
$image_info = getimagesize($image_file);
$base64_image_content = array();
$base64_image_content[image_info] =$image_info;
$base64_image_content[base64_contents] = chunk_split(base64_encode(file_get_contents($image_file)));
return $base64_image_content;
}
public function ArticleCoverFile() {
return  $this->file_base . $this->file_image_base . "/" . $this->articleno . "/" . $this->articleno . "s" . ".jpg";
}
public function ArticleCover() {
$file = $this->ArticleCoverFile();
if (file_exists ( $file )) {
return file_get_contents ( $file );
} else {
return "封面不存在";
}
}
}

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
