laravel和laravel-admin ， EasyWeChat，WangEditor

**本片博客主要介绍了 laravl和laravel-admin的使用，EasyWeChat结合laravel的使用，laravl-admin后台调取，

WangEditor富文本编辑器。

关于laravel和laravel-admin的使用

首先去多看文档吧
大概流程就是先去composer laravel框架然后配置数据库然后安装laravl-admin官网文档进行安装laravel-admin框架

关于laravel微信公众号开发基于EasyWeChat
验证token
use EasyWeChat\Factory;
class TokenController extends Controller
{
public function wxtoken(Request $request)
{
/* $signature = $request->input('signature');
$timestamp = $request->input('timestamp');
$nonce = $request->input('nonce');
$echoStr = $request->input('echostr');
if ($this->checkSignature($signature, $timestamp, $nonce)) {
ob_end_clean(); //必须清空缓冲区

        return $echoStr;
    } else {
        return 'Token verification failed.';
    }*/
    $options = [
        'app_id'    => '####',
        'secret'    => '###',
        'token'     => 'loveerys',//和公众号后台匹配的token  确保公众号访问 一至
        'aes_key' => '####',
        'log' => [
            'level' => 'debug',
            'file'  => '/tmp/easywechat.log',
        ],
        'oauth' => [
            'scopes'   => ['snsapi_userinfo'],
            'callback' => '/serve',
        ],
    ];

    $app = Factory::officialAccount($options); //调取EasyWeChat公众号类
    $app->server->push(function ($message) {
      //  $message['FromUserName']; // 用户的 openid
        $message_text =Reply::find(1);
        return "$message_text->text";
    });            //自动回复
   /* $message = $app->server->getMessage();
    var_dump($message);exit;*/
    $response = $app->server->serve();
    return $response;

}
/**
 * 微信官方提供的验签方法
 *
 * @param $signature
 * @param $timestamp
 * @param $nonce
 * @return bool
 */
private function checkSignature($signature, $timestamp, $nonce)
{
    $token = 'loveerys';
    $tmpArr = array($token, $timestamp, $nonce);
    sort($tmpArr, SORT_STRING);
    $tmpStr = implode($tmpArr);
    $tmpStr = sha1($tmpStr);

    if ($tmpStr == $signature) {

        return true;
    } else {
        return false;
    }
}

}

laravl 授权网页获取微信用户信息

/访问/
public function test(Request $request){
$appid='##';
$redirect_uri = urlencode ( 'http://###.###.#/mobile/user');
$url ="https://open.weixin.qq.com/connect/oauth2/authorize?appid=$appid&redirect_uri=$redirect_uri&response_type=code&scope=snsapi_base&state=1#wechat_redirect";
header("Location:".$url);

}
/*跳转*/
public function  user(){
    $appid = "#####";
    $secret = "##";
    $code = $_GET["code"];
    //access_token
    $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$secret";
    $token =$this->getJson($url);
    //openid
    $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code";
    $oauth2 = $this->getJson($oauth2Url);
    $access_token = $token["access_token"];
    $openid = $oauth2['openid'];
    $get_user_info_url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=$access_token&openid=$openid&lang=zh_CN";
    $userinfo = $this->getJson($get_user_info_url);
    var_dump($userinfo);exit;
}

public function getJson($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
return json_decode($output, true);
}

laravel-admin 引入第三方 WangEditor文本编辑器上传文字和图片
首先去WangEditor官方下载WangEditor文件包我用的是wangEditor-3.0.16

把下载好的包放在laravel框架vendor目录下

再damin/建立 Extensions文件夹文件夹下建立WangEditor.php
WangEditor.php内容
<?php
namespace App\Admin\Extensions;
use Encore\Admin\Form\Field;
class WangEditor extends Field
{
protected $view = 'admin.wang-editor';

protected static $css = [
    '/vendor/wangEditor-3.0.16/release/wangEditor.min.css',
];
protected static $js = [
    '/vendor/wangEditor-3.0.16/release/wangEditor.min.js',
];
public function render()
{
    $name = $this->formatName($this->column);

    $this->script = <<<EOT

http/controller/ 下建立 UploadsController 注意大小写

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;

class UploadsController extends Controller
{
public function uploadImg(Request $request)
{

    $file = $request->file("mypic");

    if (!empty($file)) {
        foreach ($file as $key => $value) {
            $len = $key;
        }
        if ($len > 25) {
            return response()->json(['ResultData' => 6, 'info' => '最多可以上传25张图片']);
        }
        $m = 0;
        $k = 0;
        for ($i = 0; $i <= $len; $i++) {
            // $n 表示第几张图片
            $n = $i + 1;
            if ($file[$i]->isValid()) {
                if (in_array(strtolower($file[$i]->extension()), ['jpeg', 'jpg', 'gif', 'gpeg', 'png'])) {
                    $picname = $file[$i]->getClientOriginalName();//获取上传原文件名
                    $ext = $file[$i]->getClientOriginalExtension();//获取上传文件的后缀名
                    // 重命名
                    $number = mt_rand(1000000000,9999999999);
                    $filename = time() .$number . "." . $ext;

                    if ($file[$i]->move("uploads/images", $filename)) {
                        $newFileName = '/' . "uploads/images" . '/' . $filename;
                        $m = $m + 1;
                        // return response()->json(['ResultData' => 0, 'info' => '上传成功', 'newFileName' => $newFileName ]);
                    } else {
                        $k = $k + 1;
                        // return response()->json(['ResultData' => 4, 'info' => '上传失败']);
                    }
                    $msg = $m . "张图片上传成功 " . $k . "张图片上传失败<br>";
                    $return[] = ['ResultData' => 0, 'info' => $msg, 'newFileName' => $newFileName];
                } else {
                    return response()->json(['ResultData' => 3, 'info' => '第' . $n . '张图片后缀名不合法!<br/>' . '只支持jpeg/jpg/png/gif格式']);
                }
            } else {
                return response()->json(['ResultData' => 1, 'info' => '第' . $n . '张图片超过最大限制!<br/>' . '图片最大支持2M']);
            }
        }
    } else {
        return response()->json(['ResultData' => 5, 'info' => '请选择文件']);
    }
    return $return;
}

}
