$ book = array('book1','book2'); $ book数组元素数是可变的.它可能有2个元素或20个元素
我需要进行这样的查询:

select * from book where bookname like %book1% or bookname like %book2%

要在laravel 5中进行此查询,可以选择:

$name = DB::Table('bookinfo')
          ->select('*')
          ->wherein('bookname',$book)
          ->get();

但它使用=运算符我需要使用like运算符

我正在使用windows 10 bash来使用tcpdump从教程中我发现听一个接口命令是:

tcpdump -i eth0 //eth0 is ethernet interface
tcpdump -i any // to listen to any interface

在这两种情况下,我得到tcpdump:socket:无效的参数错误.注意:

tcpdump -D

不会在控制台上打印任何内容.

我按照教程:http : //krzysztofzuraw.com/blog/2016/haystack-elasticsearch-part-two.html http://www.techstricks.com/django-haystack-and-elasticsearch-tutorial/

一切正常但是当我尝试从搜索框中查询某些内容时,它显示没有找到结果,并且在控制台中出现此错误.

我正在尝试安装 Chocolatey

https://chocolatey.org/install

并使用命令：
