WordPress使用WP-PostViews实现网站上显示文章的浏览量

WordPress的使用很方便，但是文章的点击浏览量默认是没有的，本文介绍用WP-PostViews实现网站上显示文章的浏览量的功能。效果如下图所示：

安装WP-PostViews插件

在插件界面中安装WP-PostViews插件，并且启用插件。

修改主题文件(Twenty Fourteen)

修改content.php，找到如下代码：

<div class="entry-meta">
	<?php
		if ( 'post' == get_post_type() )
			twentyfourteen_posted_on();

		if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :
	?>
	<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyfourteen' ), __( '1 Comment', 'twentyfourteen' ), __( '% Comments', 'twentyfourteen' ) ); ?></span>
	<?php
		endif;

		edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );
	?>
</div><!-- .entry-meta -->

<?php

if ( 'post' == get_post_type() )

twentyfourteen_posted_on();

if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :

<?php

endif;

edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );

</div>

在后面添加：

<?php 
	/*View Counter for  wp-postviews*/
	if(function_exists('the_views')) { the_views(); } 
?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

修改后的结果如下：

<div class="entry-meta">
	<?php
		if ( 'post' == get_post_type() )
			twentyfourteen_posted_on();

		if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :
	?>
	<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyfourteen' ), __( '1 Comment', 'twentyfourteen' ), __( '% Comments', 'twentyfourteen' ) ); ?></span>
	<?php
		endif;

		edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );
	?>
	<?php 
		/*View Counter for  wp-postviews*/
		if(function_exists('the_views')) { the_views(); } 
	?>
</div><!-- .entry-meta -->

<?php

if ( 'post' == get_post_type() )

twentyfourteen_posted_on();

if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :

<?php

endif;

edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

</div>

修改主题文件(Twenty Fifteen)

修改content.php，找到如下代码：

<footer class="entry-footer">
	<?php twentyfifteen_entry_meta(); ?>
	<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>
</footer><!-- .entry-footer -->

<?php twentyfifteen_entry_meta(); ?>

<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>

</footer>

在后面添加：

<?php 
	/*View Counter for  wp-postviews*/
	if(function_exists('the_views')) { the_views(); } 
?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

修改后的结果如下：

<footer class="entry-footer">
	<?php twentyfifteen_entry_meta(); ?>
	<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>
	<?php 
		/*View Counter for  wp-postviews*/
		if(function_exists('the_views')) { the_views(); } 
	?>
</footer><!-- .entry-footer -->

<?php twentyfifteen_entry_meta(); ?>

<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

</footer>

LMbench 3.0移植到Android并测试内存带宽

LMbench是个可移植的，用于评价系统综合性能的多平台开源benchmark，能够测试包括文档读写、内存操作、进程创建销毁开销、网络等性能。通过以下步骤操作，即可将LMbench移植到Android上。

下载LMbench源码

下载地址http://sourceforge.net/projects/lmbench/
也可在本站下载

修改LMbench代码

1.解压缩到指定的目录，保证最终的目录如下：

├── lmbench3/

│ ├── jni/

│ ├── doc/

│ ├── result/

│ ├── scripts/

│ ├── src/

│ ├── ACKNOWLEDGEMENTS

│ ├── CHANGES

│ ├── COPYING

│ ├── COPYING-2

│ ├── hbench-REBUTTAL

│ ├── Makefile

│ ├── README

2.修改“src/bench.h”的38行，40行，注释掉“#include <rpc/rpc.h>”，“#include <rpc/types.h>”，然后添加如下定义

#ifndef S_IREAD 
#define S_IREAD S_IRUSR
#endif

#ifndef S_IWRITE
#define S_IWRITE S_IWUSR
#endif

#ifndef S_IREAD

#define S_IREAD S_IRUSR

#endif

#ifndef S_IWRITE

#define S_IWRITE S_IWUSR

#endif

3.添加根目录下面Android.mk，jni/目录下面内容如下：

Windows下VirtualBox直接使用物理硬盘作虚拟机磁盘

目前VirtualBox只能用命令行来建立磁盘才可以使用物理硬盘。

我们假定VirtualBox安装在“D:\Program Files\Oracle\VirtualBox”这个目录下面，要在“D:\Users\VirtualBox VMs\Ubuntu\”目录下面生成文件，则执行如下命令：

"D:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands createrawvmdk -filename "D:\Users\VirtualBox VMs\Ubuntu\Ubuntu.vmdk" -rawdisk \\.\PhysicalDrive1

1	"D:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands createrawvmdk -filename "D:\Users\VirtualBox VMs\Ubuntu\Ubuntu.vmdk" -rawdisk \\.\PhysicalDrive1

\.\PhysicalDrive1 表示机器上的第二块硬盘，\.\PhysicalDrive0是第一块，\.\PhysicalDrive2是第三块，以此类推。

在Windows 的磁盘管理中能看到硬盘的分区路径。如下图所示：

然后新建虚拟机，选择"使用已有的虚拟硬盘文件"，找到刚刚创建的 Ubuntu.vmdk 即可。

对于Windows 8.1/10系统，以上的命令需要以管理员启动命令行的方式下启动并执行，否则会报告找不到磁盘。另外启动Virtual Box的时候，同样需要以管理员的身份运行，否则会出现VERR_ACCESS_DENIED错误，如下图所示：

VERR_ACCESS_DENIED

使用grunt压缩代码&配置多个任务

grunt是node环境下一个压缩、合并 js、css代码的工具，还可以做一下代码美化等。体验了一下压缩合并，还是不错的，大概流程如下：

在工程下建一个grunt目录，写两个文件 package.json-工程依赖Gruntfile.js-压缩任务

package.jsn:

{
  "name": "xxx",
  "version": "v0.1.0",
  "devDependencies": {
    "grunt": "^0.4.5",
    "grunt-contrib-concat": "~0.5.1",
    "grunt-contrib-cssmin": "~0.12.3",
    "grunt-contrib-jshint": "~0.10.0",
    "grunt-contrib-nodeunit": "~0.4.1",
    "grunt-contrib-uglify": "~0.5.0",
    "grunt-htmlhint": "~0.9.2"
  }
}

{

"name": "xxx",

"version": "v0.1.0",

"devDependencies": {

"grunt": "^0.4.5",

"grunt-contrib-concat": "~0.5.1",

"grunt-contrib-cssmin": "~0.12.3",

"grunt-contrib-jshint": "~0.10.0",

"grunt-contrib-nodeunit": "~0.4.1",

"grunt-contrib-uglify": "~0.5.0",

"grunt-htmlhint": "~0.9.2"

}

Gruntfile.js:

module.exports = function(grunt) {
    // 配置参数
    grunt.initConfig({
        pkg:grunt.file.readJSON('package.json'),
        // 代码合并
        concat:{
            options:{
                separator: ";",
                stripBanners: true
            },
            dist:{
                src:[
                    "../focusManager/base.js",
                    "../focusManager/tween.js",
                    "../focusManager/widget.js",
                    "../focusManager/yunos.js"
                ],
                dest: "dest/focusManager.js"
            }
        },
        // 代码压缩
        uglify:{
            options:{

            },
            dist:{
                files:{
                    "dest/focusManager-min.js" : "dest/focusManager.js"
                }
            }
        },
        // css压缩
        cssmin: {
            options: {
                keepSpecialComments: 0
            },
            compress:{
                files:{
                    "dest/default.css": [
                        "../focusManager/base.css",
                        "../focusManager/reset.css"
                    ]
                }
            }
        }

这个Gruntfile很容易理解，想要压缩的文件以及目标文件写好就行，还有另一种自动化的写法，后面再说。

之后运行命令，grunt

出现了一个错误，网上解释

Note that installing grunt-cli does not install the grunt task runner! The job of the grunt CLI is simple: run the version of grunt which has been installed next to a Gruntfile. This allows multiple versions of grunt to be installed on the same machine simultaneously.

So in your project folder, you will need to install (preferably) the latest grunt version:

也就是说，之前装的grunt-cli只是grunt的运行环境，在工程目录下，还需要装一下grunt，运行一下命令：

$npm install grunt --save-dev

Option --save-dev will add grunt as a dev-dependency to your package.json. This makes it easy to reinstall dependencies.

$npm install grunt --save-dev

Option --save-dev will add grunt as a dev-dependency to your package.json. This makes it easy to reinstall dependencies.

之后再次运行grunt命令，又出现错误：

好吧，没有装这三个插件？原来是grunt一样，也要在工程下装，分别运行 npm install装一下，运行，成功：

工程复杂之后，肯定不会一个一个手动填文件，grunt也可以通过逻辑自动压缩js css文件，Gruntfile.js写法：

module.exports = function(grunt) {
    // 任务配置
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        // 压缩JS

逻辑也很简单，就是把src里面的文件，压缩，生成文件会经过rename函数处理。

这里面需要注意的地方有

src: ['*.js', '**/*.js'],

1	src: ['.js', '/.js'],

如果只写一个*.js，是不会递归cwd目录下的所有文件的，要递归几级写到数组中就可以了，如果不想添加什么文件，加！符号-‘！*.min.js’。

当然，这次也没有一帆风顺，运行的时候遇到错误：

报错在最后一句，

grunt.registerTask('default', ['uglify', 'cssmin']);

1	grunt.registerTask('default', ['uglify', 'cssmin']);

查了半天也没找到这里有什么错误，网上搜了一下，大多数是中括号里的uglify没有引号，跟我的情况也不一样。后来仔细检查了一下代码，发现了两处拼写错误，改了后就运行通过了，也就是说，其他错误都会报到最后一句。

做了一个小小的试验，写一个空模块

(function(){
    // for test
})();

(function(){

// for test

})();

压缩后是这样的：

对，什么都没了。

最近有新的需求，压缩不同版本的文件，就需要开多个contact uglify任务，琢磨了一会，搞出来了，同时对grunt有了进一步的认识。

配置多任务是这么写的

};

r简单看一下配置文件

contact

首先配置了option，option中配置了不同文件中间增加;分隔符。

这个是contact所有任务的全局配置

后面又写了三个合并任务，分别配置下src和dest就可以了。

合并顺序就是 src中配置的顺序，*.js则按照字母排序。

uglify

uglify中配置了三个压缩任务，

压缩contact的文件

压缩所有文件并生成.min.js

最后运行

grunt.registerTask('default', ['concat', 'uglify']);

1	grunt.registerTask('default', ['concat', 'uglify']);

会自动加载contact和uglify中的所有任务。
