【玩转腾讯云】Laravel 笔记，持续更新中...

发布于

1.composer install或者其他操作报:

代码语言：javascript
复制
A version is required for an API group definition.

可能1：.env文件没有

2.laravel-admin 显示图片在图片地址前添加admin域名，例如：

代码语言：javascript
复制
127.0.0.1:8000/admin/127.0.0.1:8000/uploads/images/1.jpg

原因：.env设置APP_URL错误

代码语言：javascript
复制
错误：APP_URL=127.0.0.1:8000

正确：APP_URL=http://127.0.0.1

3.模仿dingoapi 返回分页

代码语言：javascript
复制


dataList = paginator->transform(function ($item){

data = transformer->transformData($item);

return $data;

});

4.laravel-admin上传多张图片

controller：

代码语言：javascript
复制
 form-&gt;multipleImage(&#39;images&#39;, &#39;上传图片&#39;);</code></pre></div></div><p>model：</p><div class="rno-markdown-code"><div class="rno-markdown-code-toolbar"><div class="rno-markdown-code-toolbar-info"><div class="rno-markdown-code-toolbar-item is-type"><span class="is-m-hidden">代码语言：</span>javascript</div></div><div class="rno-markdown-code-toolbar-opt"><div class="rno-markdown-code-toolbar-copy"><i class="icon-copy"></i><span class="is-m-hidden">复制</span></div></div></div><div class="developer-code-block"><pre class="prism-token token line-numbers language-javascript"><code class="language-javascript" style="margin-left:0"> public function getImagesAttribute(value){

array = explode(&#39;,&#39;, value);

return $array;

}

public function setImagesAttribute($value){

this-&gt;attributes[&#39;images&#39;] = implode(&#39;,&#39;, value);

}

5.接口请求数据库写字段写入不进去

代码语言：javascript
复制
model中$fillable添加字段

6.composer 无法下载扩展文件的问题

代码语言：javascript
复制

原因：composer 全局下载换成中国镜像.

解决：下载源换回默认。修改 composer 配置

composer config -g repo.packagist composer https://packagist.phpcomposer.com


7.报bootstrap/cache directory must be present and writable.错误

mkdir cache

php artisan cache:clear
