目前,我可以使用以下正则表达式从任何URL中提取"域名":

/^(?:https?:\/\/)?(?:[^@\n]+@)?(?:www\.)?([^:\/\n\?\=]+)/im

但是我也得到了子域名,我想避免.例如,如果我有网站:

• www.google.com
• yahoo.com/something
• freds.meatmarket.co.uk?someparameter
• josh.meatmarket.co.uk/asldf/asdf

我目前得到:

• google.com
• yahoo.com
• freds.meatmarket.co.uk
• josh.meatmarket.co.uk

最后两个我想排除freds和josh子域部分,只提取真正的域meatmarket.co.uk.

我确实找到了另一个尝试在PHP中解决的SOF,不幸的是我不知道PHP.这可以翻译成JS(我实际上是使用Google Script FYI)吗？

  function topDomainFromURL($url) {
    $url_parts = parse_url($url);
    $domain_parts = explode('.', $url_parts['host']);
    if (strlen(end($domain_parts)) == 2 ) { 
      // ccTLD here, get last three parts
      $top_domain_parts = array_slice($domain_parts, -3);
    } else {
      $top_domain_parts = array_slice($domain_parts, -2);
    }
    $top_domain = implode('.', $top_domain_parts);
    return $top_domain;
  }

我很好奇是否有人知道如何查询 Elasticsearch 索引中的多个子字段。例如记录：

{
  "foo": [
    {
      "bar": "Good example",
      "subfield":  32
    }
  ]
},
{
  "foo": [
    {
      "bar": "Good example",
      "subfield":  50
    }
  ]
},
{
  "foo": [
    {
      "bar": "Bad example",
      "subfield":  32
    }
  ]
}

我希望构建一个foo.bar = "Good example" AND foo.subfield = 32仅返回第一条记录的查询。欢迎使用 Elasticsearch 的查询 DSL 或查询字符串。

使用Powermockito和Mockito为连接池构建一些简单的单元测试时遇到以下错误,我将其包裹在Hikari CP中.测试的设置如下.令我感到困惑的是,我有一些未显示的单元测试,它们都使用相同的设置和方法.只是这一个单元测试继续失败并出现该错误.无论when我把什么陈述放在顶部,他们都找不到方法.

试图解决臭名昭著的SLF4J多重绑定问题。这里有大约一百万个针对Maven的解决方案，但是没有一个可以翻译成Gradle（显然不是Gradle专家）。我已经尝试了一些解决方案，configurations但是都没有正常工作。这是我遇到的错误（正如我提到的，我试图抑制警告）

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in     [jar:file:~/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-nop/1.7.22/3a4392836f875995446373b008e39cdb9a532fbe/slf4j-nop-1.7.22.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:~/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-slf4j-impl/2.7/382b070836b8940a02d28c936974db95e9bfc3a4/log4j-slf4j-impl-2.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.helpers.NOPLoggerFactory]

这是我的项目中唯一的SLF4J依赖项：

dependencies {
    compile group: 'org.slf4j', name: 'slf4j-nop', version: '1.7.+'
    ...
}

另外，如果有帮助，我在运行单元测试时也会遇到问题。

更新：找出了一种依赖关系是使用org.apache.logging，而org.apache.logging则使用了SLF4J。如果我排除了apache logger的组，则整个程序将失败，因为该依赖项会引发ClassNotFoundException。那么现在怎么办？
