小编bos*_*ari的帖子

这是我的代码 -

import subprocess
import sys

HOST="xyz3511.uhc.com"
# Ports are handled in ~/.ssh/config since we use OpenSSH
COMMAND="uptime"

ssh = subprocess.Popen(["ssh", "%s" % HOST, COMMAND],
                       shell=True,
                       stdout=subprocess.PIPE,
                       stderr=subprocess.PIPE)
result = ssh.stdout.readlines()
if result == []:
    error = ssh.stderr.readlines()
    print (sys.stderr, "ERROR: %s" % error)
else:
    print (result)

这是我得到的错误-

错误: [b"'ssh' 不是内部或外部命令，\r\n"，b'可运行的程序或批处理文件。\r\n']。

不知道我在这里做错了什么。另外，我没有提到任何端口。我想要的只是使用子进程并连接到远程服务器，执行一个简单的命令，如ls. Python 版本是 3.x。

我正在尝试从 https 调用获取响应，该调用已在其端安装了证书。这是我的代码

import requests
import urllib3

urllib3.disable_warnings()

cert_file_path = "/path/output-crt-file-name.crt"
key_file_path = "/path/output-key-file-name.key"
passwd = 'secretpass'
print(passwd)
url = "https://url/to/fetch/response"
params = {"AppID": "xxxx", "Safe": "xxxx", "Folder": "Root",
          "Object": "xxxx"}
cert = (cert_file_path, key_file_path, passwd)
r = requests.get(url, params=params, cert=cert, verify=True )
print(r.text)

这会引发错误

由 SSLError('客户端私钥已加密，需要密码'引起)

请建议。

只是数据.状态选项卡中的数据库大小应为0 MB.
是否有任何API可以完成工作,如果我尝试使用unix命令清除所有目录,该怎么办？推荐吗？

如何从查询控制台找到可能的查询？

我知道时间段。

它在历史仪表板中不像在历史仪表板中那样可用。我只能看到过去 10 分钟的长时间运行的查询。

也许如果我能获得正确的 URI 来探索应用程序服务或计量数据？

始终建议使用xdmp:estimate而不是fn:count.我知道如何在cts中使用它:搜索但不确定可搜索的XPath表达式.例如,我试图search:facets在执行后返回返回的计数search:search,就像这样 -
xdmp:estimate($search-result/search:facet/search:facet-value)但是
XDMP-UNSEARCHABLE-- Expression is unsearchable在使用fn:count工作时我得到错误.
救命!

我有480个值的序列.我想一次总计8个值并返回总和.对于前者 可以说我有一系列的价值观 -

我希望查询返回1到8个值的总和,然后返回第9到16个值,依此类推.

假设我有一个XML-

<SearchPage ID="123" version="1.3" xmlns="http://some/path">
   .....some child elements
</SearchPage>  

如何从中获取所有属性名称？

我有一段代码,我想返回特定林中的文档总数.我想确定林文档计数是0还是更多.

 declare function local:forest-doc-count($db-name,
                                        $f-id as xs:unsignedLong) as xs:integer {
  let $_ := xdmp:log(xdmp:describe(fn:concat("$db-name -->", $db-name), (),()))                    
    let $query := 'xquery version "1.0-ml";
                    declare variable $f-id as xs:unsignedLong external;
                   xdmp:estimate(cts:search(fn:doc(), (), (), (), $f-id))'
    let $count := xdmp:eval($query , (),
                    map:entry("f-id",   $f-id),
                    map:entry("database", xdmp:database($db-name))
                    )
    return $count
};

其中$ f-id是林ID,$ db-name是数据库名称.现在我得到了

未定义的变量$ f-id

我正在根据时间戳从米数据库中提取 uri 列表。这是代码 -

cts:uris( (),  (),  cts:and-query((
                cts:collection-query("meters") ,
                cts:element-value-query(xs:QName("mt:period"), "raw"),
                cts:element-range-query( xs:QName("mt:end-time"),  ">=", xs:dateTime("2018-02-17T05:37:00") ),
)
                 )
                              ))
