微信开发笔记

1、token验证。服务器地址：http://***/public/index.php/index/Wechat/index
文件路径：\application\index\controller\Wechat.php

<?php
namespace app\index\controller;

use think\facade\Config;
use think\facade\Request;

class Wechat{
    public function index(){
        $token     = Config::get('wechat.official_account.default.token');    
        $echostr   = 'failure';  
        $timestamp =Request::get('timestamp');          //input('timestamp');//
        $nonce     =Request::get('nonce');              //input('nonce');// 
        $signature = Request::get('signature');         //input('signature');//
       
        $list     = array($token, $timestamp, $nonce);
        $hashcode = sort($list, SORT_STRING) ? sha1(implode('', $list)) : '';
        if($hashcode == $signature) {
            $echostr =input('echostr');
        }
        return $echostr;    // 验证时必须关闭调试模式
    }
}

 

ThinkPHP 笔记

1、查看版本号

\thinkphp\library\think\App.php

2、模板输出

目录结构

index.php 内容

<?php
namespace app\index\controller;

use think\Controller;

class Index extends Controller
{
    public function index(){              
       return $this->fetch();          
    }
}

2.1、模板 比较标签

{lt name="product.total_count" value="$product.min_count"}    
    <div class="ProductCountLow">
        库存不足：{$product.total_count}/{$product.min_count}
    </div>
{/lt}

{egt name="product.total_count" value="$product.min_count"}    
    <div class="ProductCount">
        库存：{$product.total_count}
    </div>
{/egt}

2.2、输出关联对象

public function unit(){
   return $this->belongsTo("CateProductUnitModel")->field("id","name");
}
{$product.unit.name}

 

3、路由

以下路由定义匹配，当访问 http://domain.com/index.php/product时，转到 http://domain.com/index.php/index/Product/index。写链接时别忘了index.php

Route::rule('product','index/Product/index');

4、常量问题

参考：https://blog.csdn.net/yiyuwu7069/article/details/78466400

5、文件上传

 

composer 更新报错:SSL/TLS

在项目下执行一下更新命令时报错：

composer update

[Composer\Exception\NoSslException]
The openssl extension is required for SSL/TLS protection but is not available. If you can not enable the openssl extension, you can disable this error, at your own risk, by setting the ‘disable-tls’ option to true. 

 

=======================

解决方法

进入php.ini 修改配置打开ssl

//将这行代码前的 ; 去掉
extension=php_openssl.dll

 

Devexpress 笔记

GridView显示行号

Private Sub GridView1_CustomDrawRowIndicator(sender As Object, e As DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs) Handles GridView1.CustomDrawRowIndicator
     e.Info.DisplayText = e.RowHandle.ToString()
End Sub
