修复Robolectric 4.6.x报错Failed to transform bcprov-jdk15on-1.68.jar
参照 Android Studio 3.6.3/4.0/4.1/4.2配置Robolectric-4.5.1,Powermock-1.6.6单元测试环境 配置执行单元测试。
项目使用 Android Studio 4.1.3 ，Android Gradle构建工具（AGP）版本
com.android.tools.build:gradle:4.1.3
单元测试使用的 Robolectric 从 4.5.x 升级到 4.6.x ，编译时产生如下报错：
Failed to transform bcprov-jdk15on-1.68.jar (org.bouncycastle:bcprov-jdk15on:1.68) to match attributes {artifactType=processed-jar, org.gradle.category=library, org.gradle.libraryelements=jar, org.gradle.status=release, org.gradle.usage=java-runtime}.

Reason: IllegalArgumentException, message: Unsupported class file major version 59. (Run with --stacktrace for more details.)
问题排查了一下，发现 Robolectric 4.6.x 引入了 bcprov-jdk15on-1.68.jar ，这个库是使用 Java 15 编译的。
如果项目在 gradle.properties 中配置了 android.enableJetifier=true （目的是转换第三方不支持 AndroidX 的依赖，用以使整个工程升级到 AndroidX ）, 当 Jetifier 小于等于 Jetifier 1.0.0-beta10时，无法反编译高于 Java 13 编译的代码库，进而引起上面的报错。
目前（2021/07/22）最新的 Android Studio 4.2.2 ，Android Gradle构建工具（AGP）版本
com.android.tools.build:gradle:4.2.2
依旧没有完成适配工作。
官方回复是 Android Gradle构建工具（AGP） 7.x版本修复，估计要到Android Studio 4.3 版本了。
目前的解决方法是在 gradle.properties 中配置 Jetifier 忽略 bcprov 库。比较庆幸的是 bcprov 库跟 AndroidX 没什么关系，因此忽略这个库是安全的。
如下：
android.enableJetifier=true android.jetifier.blacklist=org.robolectric.*,bcprov # Android Studio 4.2 版本开始使用 android.jetifier.ignorelist 替代 android.jetifier.blacklist

关于Android Studio单元测试中“Method d in android.util.Log not mocked.”问题的解决
关于Android Studio单元测试中“Method d in android.util.Log not mocked.”问题的解决。
一般发生在 Robolectric 3.x 版本上，比如 Robolectric 3.8
解决方案：
打开对应模块的build.gradle文件

buildToolsVersion '27.0.3'
testOptions {
unitTests.returnDefaultValues = true
}

Android Studio 4.2.2 解决库依赖冲突问题
最近在引入某些库的时候，发现额外的库被引入，造成编译冲突，想具体知道是由于哪个库引起的。参照原来的Android Studio(Gradle)解决库依赖冲突问题 提示信息比较模糊，不方便定位，尤其是只在测试模块中引入某些库，业务代码不引入的情况下。
比如我们在 Android Studio 4.2.2 单元测试引入了 Robolectric 4.3.1/4.5.1，结果在业务代码不使用任何的 AndroidX 依赖的情况下，编译会报错
This project uses AndroidX dependencies，but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry. following AnroidX dependencies are detected: androidx.test:monitor:1.2.0, androidx.annotation:annotation:1.0.0
这个依赖是通过 Robolectric 4.3.1/4.5.1 引入的，解决方法是调整到 Robolectric 3.8。
Android Studio 4.2.2 自带的 Project Structure 提示更加详细，可以明确的指出到底是哪个库引入，如下图：

WordPress绑定多个域名，多个域名可同时独立访问
在未修改wp-config.php之前WordPress博客默认是不能实现多个域名独立访问的，即使我们绑定了多个域名，访问时也会自动跳转到安装站点时默认的域名，就连同一个域名带www和不带www都是自动跳转到默认域名。（这一点的不便之处深有体会，我找了几天才找到这个解决办法）
那如果我们需要WordPress绑定多个域名，并且都能度独立访问怎么办？
要想实现WordPress绑定多个域名，并且都能度独立访问也不难。我们只需修改wp-config.php文件即可，在站点根目录找到“wp-config.php”文件，然后根据自己需要添加下面任意一段代码即可。
一、实现任意域名访问
说明：在wp-config.php文件中加下面代码，就能实现绑定解析的域名都能正常访问博客，而且不会串联到其他域名。
define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST']);
二、限制特定域名访问
也可以只指定某些域名可以访问。注意把`$domain = array('linqingmaoer.cn', 'www.linqingmaoer.cn');`括号内的域名改成你自己需要绑定的域名。这样就可以设置成你添加的这几个域名能正常访问。而其他未添加的域名则无法访问。
$domain = array('linqingmaoer.cn', 'www.linqingmaoer.cn');
if(in_array($_SERVER['HTTP_HOST'], $domain)) {
define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST']);
}
2. 在完成上面的工作以后，你的网站已经可以实现多域名访问了，但是还是有一个问题，那就是静态资源，在wordpress上传的图片插入文章里面，地址是固定的，修改域名以后，并不会修改图片的域名，所以还需要修改静态文件地址，使用以下代码可以解决：
define( 'WP_CONTENT_URL', '/wp-content');
把这段代码加入上面的代码下面即可。
注意上述代码需要添加在
/** Sets up WordPress vars and included files. */ require_once(ABSPATH . 'wp-settings.php');
的前面。
注意，上述配置之后，可能会出现跨域相互访问问题，需要配置跨域访问属性，如下：
指定多个域名（http://client1.xxx.com、http://client2.xxx.com等）跨域访问，则只需在server.php文件头部添加如下代码：
$origin = isset($_SERVER['HTTP_ORIGIN'])? $_SERVER['HTTP_ORIGIN'] : '';
$allow_origin = array(
'http://client1.xxx.com',
'http://client2.xxx.com'
);
if(in_array($origin, $allow_origin)) {
header('Access-Control-Allow-Origin:'.$origin);
}

WordPress 5.7.2多域名指向同一网站根据来源域名不同返回不同的网站标题
以前备案了多个独立网站，每次注册的时候，提交备案域名的网站标题都是不同的。现在多个网站同时指向了同一台服务器，现在就需要根据来源域名的不同，返回不同的网站标题信息，解决方法就是写自定义的拦截插件。
<?php
// 根据域名的来源不同，返回不同的网站标题
function domain_page_title($title)
{
$domain = $_SERVER['HTTP_HOST'];
if((0 == strcasecmp('www.mobibrw.com',$domain)) || (0 == strcasecmp('mobibrw.com',$domain))) {
$title['title'] = '深海游弋的鱼'; //网站描述
}
return $title;
}
add_filter('document_title_parts', 'domain_page_title', 10, 1);
?>
在主题functions.php中添加如上代码，用来自定义分隔符号和对已生成的title标题进行二次修改。

Shell while循环修改外部变量无效
工作中想遍历文件中的每行，并且赋值给一个变量，使用下面写法，但是循环遍历后变量依然为空，值没有变化。如下：
$ cat temp.txt
http://www.baidu.com
http://www.jd.com
http://www.huawei.com
$ cat temp.sh
#! /bin/bash
file_path=temp.txt
new_var=''
cat ${file_path} | while read line
do
new_var="${new_var}${line};"
echo ${line}_____
done
echo "${new_var}+++++"
$ source temp.sh
http://www.baidu.com_____
http://www.jd.com_____
http://www.huawei.com_____
+++++
上面未赋值成功是因为使用了管道符，将值传给了while，使得while在子shell中执行，子shell中的变量等在循环外无效。
可以写为：
$ cat temp.sh
#! /bin/bash
file_path=temp.txt
new_var=''
while read line
do
new_var="${new_var}${line};"
echo ${line}_____
done <<< "$(cat ${file_path})"
echo "${new_var}+++++"
$ source temp.sh
http://www.baidu.com_____
http://www.jd.com_____
http://www.huawei.com_____
http://www.baidu.com;http://www.jd.com;http://www.huawei.com;+++++
或者：
$ cat temp.sh
#! /bin/bash
file_path=temp.txt
new_var=''
while read line
do
new_var="${new_var}${line};"
echo ${line}_____
done < ${file_path}
echo "${new_var}+++++"
$ source temp.sh
http://www.baidu.com_____
http://www.jd.com_____
http://www.huawei.com_____
http://www.baidu.com;http://www.jd.com;http://www.huawei.com;+++++
或者指定换行符读取：
#! /bin/bash IFS=" " for LINE in `cat /etc/passwd` do echo $LINE done
或者用read读取文件重定向：
#! /bin/bash while read LINE do echo $LINE done < /etc/passwd
