Android OTA应用访问Thinkphp5 服务器

从学习服务器端Thinkphp5 到现在已有半个月，目前为止，尝试做的OTA后台服务器已经可以运行，手机端的OTA应用也可以通过服务器下载升级包并完成升级。

这期间还是能学习到不少东西的，比如php、html、js、数据库、网络等，实践证明多动手才能发现问题，才能发现不足。

多学习才能发现自己的无知，才体会到知识的浩瀚无穷和力量。

服务器做好了，如何访问服务器呢？

1. 可以通过Html网页访问，提交数据。比如浏览器，html 是运行在客户端的，html里的数据是服务器返回的。

http://localhost/public/index.php/admin/login/index.html

2. 也可以通过下面这样访问，直接访问控制器Device的checkNewVersion函数，后面带参数，红色是参数名，后面跟参数值。一般这个的形式称作get方式

http://localhost/public/index.php/home/Device/checkNewVersion/project_name/U501/version_name/version1111/device_number/sn11111

这种方式可以在浏览器里直接输入，也可以在应用里代码提交。

3. 因为get方式提交，参数可见，所以大多时候需要post方式。

如下，要实现手机是否有新版本软件需要升级，访问home模块的Device控制器checkNewVersion函数

private static final String serverUrl = "http://192.168.23.1/public/index.php/home/Device/checkNewVersion";

手机应用端提交请求

private void checkNewVersionInner() throws Exception {String getData = null;boolean hasNewVersion = false;Map<String, String> parames = new HashMap<String, String>();parames.put("project_name", MODEL);parames.put("version_name", RELEASE);parames.put("device_number", "123456789012345");getData = HttpUtil.sendPostRequest(serverUrl, parames, "UTF-8");

    public static String sendPostRequest(String path,               Map<String, String> params, String enc) throws Exception{                    // title=dsfdsf&timelength=23&method=save          StringBuilder sb = new StringBuilder();        if(params!=null && !params.isEmpty()){              for(Map.Entry<String, String> entry : params.entrySet()){  sb.append(entry.getKey()).append('=').append(URLEncoder.encode(entry.getValue(), enc)).append('&');            }              sb.deleteCharAt(sb.length()-1);        }        System.out.println("post: send_data:" + sb.toString());                byte[] entitydata = sb.toString().getBytes();        URL url = new URL(path);        HttpURLConnection conn = (HttpURLConnection)url.openConnection();        conn.setRequestMethod("POST");        conn.setConnectTimeout(50 * 1000);        conn.setDoOutput(true);        //Content-Type: application/x-www-form-urlencoded          //Content-Length: 38          conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");        conn.setRequestProperty("Content-Length", String.valueOf(entitydata.length));                  OutputStream outStream = conn.getOutputStream();        outStream.write(entitydata);        outStream.flush();        outStream.close();        if(conn.getResponseCode()==200){

服务器端处理请求，同时处理get和post方式。

    public function checkNewVersion($project_name='',$version_name='',$device_number='')    {        define('IS_POST',       Request::instance()->isPost());        $responed = $this->create_responed();        if(IS_POST){            $where = array(            'project_name' => $_POST['project_name'],            'version_name' => $_POST['version_name']            );            $device_number = $_POST['device_number'];        }else{         $where = array(            'project_name' => $project_name,            'version_name' => $version_name            );                    }        Log::record('check_new_version $where ' . var_export($where, true), 'error');        $Project_version = model('admin/Project')->join("darling_version","darling_version.project_id = darling_project.project_id")        ->where($where)->find();                if(!empty($Project_version)){            Log::record('check_new_version Project_version ' . var_export($Project_version, true), 'error');                        $package = model('admin/Package')            ->where("project_id=".$Project_version['project_id']." and version_id=".$Project_version['version_id']." and status>1")            ->order('create_time desc')            ->find();                      if(!empty($package)){                Log::record('check_new_version path ' . var_export($package, true), 'error');                $responed = array(                'NeedUpdate' => '1',                'Path' => $_SERVER['HTTP_HOST'].DS.$package['package_path'],                'CheckSum'=>$package['package_md5'],                'Size'=>$package['package_size'],                'TargetVersion'=>$package['target_version']                );                $path = str_replace("\\",'/',$package['package_path']);                                  $responed = $this->create_responed('1',"http://".$_SERVER['HTTP_HOST'].'/'.$path,$package['package_md5'],$package['package_size'],$package['target_version']);                    }        }          //dump($responed);        return $responed;    }//  Create XML Item    public function create_responed($NeedUpdate='0', $Path='', $CheckSum='', $Size='', $TargetVersion='' ) { $item = "<item>\n"; $item .= "    <NeedUpdate>" .$NeedUpdate. "</NeedUpdate>\n"; $item .= "    <Path>" . $Path . "</Path>\n"; $item .= "    <CheckSum>" . $CheckSum . "</CheckSum>\n"; $item .= "    <Size>" . $Size . "</Size>\n"; $item .= "    <TargetVersion>" . $TargetVersion . "</TargetVersion>\n"; $item .= "</item>\n"; return $item; }

注意，需要手机和服务器在同一个网段，才能通信。
