Thinkphp5微信小程序获取用户信息接口的实例详解

Thinkphp5微信小程序获取用户信息接口的实例详解

首先在官网下载示例代码, 选php的,

这里有个坑

官方的php文件,编码是UTF-8+的, 所以要把文件改为UTF-8

然后在Thinkphp5 extend文件夹下建立Wxxcx命名空间,把官方的几个类文件放进去(这里要注意文件夹名, 命名空间名, 类名的, 大小写,一定要一样,官方的文件名和类名大小写不一样)

然后是自己的thinkphp接口代码:

<?php /**  * Created by PhpStorm.  * User: leeoo  * Date: 2017/9/14 0014  * Time: 10:43  */  namespace app/api/controller/v1;   use think/Loader; use think/Request; use Workerman/Protocols/Http; use Wxxcx/WXBizDataCrypt; use first/second/Foo;  class Index {   public function index($id)   {      return json(['msg' => $id]);   }    public function dologin()   {     $code = Request::instance()->param('code');     $encryptedData = Request::instance()->param('encryptedData');     $iv = Request::instance()->param('iv');      $appid = "你的小程序appid";     $secret = "你的小程序secret";     //appid={$appid}&secret={$secret}&js_code={$code}&grant_type=authorization_code     $param = array(       'appid' => $appid,       'secret' => $secret,       'js_code' => $code,       'grant_type' => 'authorization_code'     );   //http函数为封装的请求函数     $res = http("https://api.weixin.qq.com/sns/jscode2session", $param, 'post');      $arr = json_decode($res, true);      $result = $this->wxdecode($encryptedData, $iv, $arr['session_key'], $appid);      //return json($result);     if ($result) {       return json(['code' => 1]);     } else {       return json(['code' => -1]);     }    }    public function wxdecode($encryptedData, $iv, $sessionKey, $appid)   {     //Loader::import('Wxxcx/WXBizDataCrypt', EXTEND_PATH);     $pc = new WXBizDataCrypt($appid, $sessionKey);     $data = null;     $errCode = $pc->decryptData($encryptedData, $iv, $data);     //echo $data;     //return json(['data'=>$data]);     $data = json_decode($data);      if ($errCode == 0) {       //print($data . "/n");       //dump($data);       return $data;     } else {       //print($errCode . "/n");       //dump($errCode);       return $errCode;     }    } } 

http封装函数:

/**  * 发送HTTP请求方法  * @param string $url  请求URL  * @param array $params 请求参数  * @param string $method 请求方法GET/POST  * @return array $data  响应数据  */ function http($url, $params, $method = 'GET', $header = array(), $multi = false){   $opts = array(     CURLOPT_TIMEOUT    => 30,     CURLOPT_RETURNTRANSFER => 1,     CURLOPT_SSL_VERIFYPEER => false,     CURLOPT_SSL_VERIFYHOST => false,     CURLOPT_HTTPHEADER   => $header   );   /* 根据请求类型设置特定参数 */   switch(strtoupper($method)){     case 'GET':       $opts[CURLOPT_URL] = $url . '?' . http_build_query($params);       break;     case 'POST':       //判断是否传输文件       $params = $multi ? $params : http_build_query($params);       $opts[CURLOPT_URL] = $url;       $opts[CURLOPT_POST] = 1;       $opts[CURLOPT_POSTFIELDS] = $params;       break;     default:       throw new Exception('不支持的请求方式！');   }   /* 初始化并执行curl请求 */   $ch = curl_init();   curl_setopt_array($ch, $opts);   $data = curl_exec($ch);   $error = curl_error($ch);   curl_close($ch);   if($error) throw new Exception('请求发生错误：' . $error);   return $data; }
