This article mainly introduces how to obtain the current url address and url parameters in nodejs. This article provides code examples. For more information, see
The Code is as follows:
// The http url of the required ModuleCurrent url http: // localhost: 8888/select? Aa = 001 bb = 002Var http = require ('http ');Var URL = require ('url ');Http. createServer (function (req, res ){Var arg = url. parse (req. url). query; // method 1 arg => aa = 001
Must understand SQL knowledge
1. query Two External table connections
There are two tables A and B:
mysql> select * from A;+------+------+| id | Col1 |+------+------+| 1 | AA || 2 | BB || 3 | CC |+------+------+3 rows in set (0.00 sec)mysql> select * from B;+------+------+| id | Col2 |+------+------+| 2 | DD || 3 | EE || 4 | FF |+------+------+3 rows in set (0.01 sec)
1. Left join between table A and Table B
First, fi
list represents the length of each directory and its relative position.Now let's do an experiment to see the difference between them.CREATE TABLE Test1 (T1 varchar () DEFAULT NULL,T2 varchar () DEFAULT NULL,T3 char (Ten) DEFAULT NULL,T4 varchar () DEFAULT NULL) Engine=innodb DEFAULT charset=latin1 row_format=compactINSERT into test1 values (' A ', ' BB ', ' BB ', ' CCC ');INSERT into test1 values (' d ', '
With the choice of jquery, eat rice rice incense, body times great ...
1. Basic
We know that the most common use of jquery is the selector, we look at the selector in Jqueryapi-basically there are 5 kinds of situations class, ID, Element, *, and there is a multiple selector, here we think about the CSS style
CSS styles also have several conditions: 1. Class style 2.id style 3. Label style,
If there is a class of a AA, then we define the style of AA to be written as. aa{}
If there is a
Comments: Disable port 21 \ 23 \ 25 in Windows. Sometimes, to ensure security, we need to disable port 21 for FTP (File Transfer Protocol) services.Port Description: port 21 is mainly used for the FTP (File Transfer Protocol) service. The FTP service is mainly used to upload and download files between two computers, one computer acts as the FTP client, and the other computer acts as the FTP server. you can log on to the FTP server using anonymous logon and authorized username and password logon.
