微信小程序 SDK

用于 PHP 方便调用微信小程序的 服务端接口

接入要求

"php": ">=5.4"

接入方式

1、composer 安装

composer require luckyhjh/wechat-mini-program

2、新建文件

新建类继承 WechatMiniProgram，并实现相关接口，token 可保存在 redis 或 mysql 等。

例如 Laravel/Lumen，可新建文件 app/Libs/WechatMiniProgram.php：

namespace AppLibs; use IlluminateSupportFacadesCache; use WechatMiniProgramApiAccessToken; use WechatMiniProgramApiException; class WechatMiniProgram extends WechatMiniProgramWechatMiniProgram { public function __construct($appid = '', $secret = '') { empty($appid) and $appid = env('WX_APPID'); empty($secret) and $secret = env('WX_SECRET'); parent::__construct($appid, $secret); } /** * 读取token * @return string */ public function getApiToken() { $cache_name = 'wx_token_' . $this->getAppid(); $access_token = Cache::get($cache_name); if ($access_token) { return $access_token; } $AccessToken = new AccessToken($this); try { $Token = $AccessToken->getAccessToken(); $access_token = $Token->access_token; $this->setApiToken($access_token, $Token->expires_in); return $access_token; } catch (ApiException $apiException) { return ''; } } /** * 保存token * @param string $access_token * @param int $expire * @return bool */ public function setApiToken($access_token, $expire = 7200) { $cache_name = 'wx_token_' . $this->getAppid(); return Cache::set($cache_name, $access_token, $expire); } }

例如 ThinkPHP，可新建文件 extend/WechatMiniProgram.php：

use WechatMiniProgramApiAccessToken; use WechatMiniProgramApiException; class WechatMiniProgram extends WechatMiniProgramWechatMiniProgram { public function __construct($appid = '', $secret = '') { empty($appid) and $appid = env('WX_APPID'); empty($secret) and $secret = env('WX_SECRET'); parent::__construct($appid, $secret); } /** * 读取token * @return string */ public function getApiToken() { $cache_name = 'wx_token_' . $this->getAppid(); $access_token = cache($cache_name); if ($access_token) { return $access_token; } $AccessToken = new AccessToken($this); try { $Token = $AccessToken->getAccessToken(); $access_token = $Token->access_token; $this->setApiToken($access_token, $Token->expires_in); return $access_token; } catch (ApiException $apiException) { return ''; } } /** * 保存token * @param string $access_token * @param int $expire * @return bool */ public function setApiToken($access_token, $expire = 7200) { $cache_name = 'wx_token_' . $this->getAppid(); return cache($cache_name, $access_token, $expire); } }

3、业务调用

业务里根据需要调用

$mp = new WechatMiniProgram(); $Auth = new Auth($mp); $User = new WechatMiniProgramApiUser($mp);//如果要调用其它接口，可复用$mp try { $session = $Auth->code2session($code); $openid = $session->openid; } catch (ApiException $apiException) { }

支持接口

AccessToken->getAccessToken()：获取小程序全局唯一后台接口调用凭据 Auth->code2session()：用 code 获取 openid User->getPhoneNumber()：获取手机号 SubscribeMessage->send()：发送订阅消息 WxaCode->getUnlimited()：生成小程序码，可接受页面参数较短，生成个数不受限 WxaCode->get()：生成小程序码，可接受 path 参数较长，生成个数受限 SecCheck->messageIsRisky()：文本是否为风险内容 SecCheck->imageIsRisky()：文本是否为风险内容
