parameters

问题 I’m trying to write a wrapper function in PowerShell that basically evaluates the first parameter and based on that runs a program on the computer. All the remaining parameters to the wrapper function should then be passed to the program that is ran as well. So it should look something like this: function test ( [string] $option ) { if ( $option -eq 'A' ) { Write-Host $args } elseif ( $option -eq 'B' ) { . 'C:\Program Files\some\program.exe' $args } } Now just adding $args does not work, so

问题 I have written a python script which calls a function. This function takes 7 list as parameters inside the function, something like this: def WorkDetails(link, AllcurrValFound_bse, AllyearlyHLFound_bse, AlldaysHLFound_bse, AllvolumeFound_bse, AllprevCloseFound_bse, AllchangePercentFound_bse, AllmarketCapFound_bse): where all the arguments except link are lists. But this makes my code looks pretty ugly. I pass these lists to this function because the function appends few values in all of these

问题 So the backend (not under my control) requires a query string like this: http://example.com/?foo=5&foo=2&foo=11 But axios uses JS object to send the request params: axios.get('http://example.com/', { foo: 5 }); And obviously such object can't have multiple fields with the same key. How can I send a request with multiple fields with same key? 回答1: From the axios documentation on the request config // `params` are the URL parameters to be sent with the request // Must be a plain object or a

问题 I have a gradle build script into which I am trying to include Eric Wendelin's css plugin - http://eriwen.github.io/gradle-css-plugin/ Its easy enough to implement, and because I only want minification (rather than combining and gzipping), I've got the pertinent parts of the build script looking like this: minifyCss { source = "src/main/webapp/css/brandA/styles.css" dest = "${buildDir}/brandA/styles.css" yuicompressor { lineBreakPos = -1 } } war { baseName = 'ex-ren' } war.doFirst { tasks

问题 I really like the way that ValidateSet works. It proposes the options as a list while you type your Cmdlet in the PowerShell ISE. I would like to know if it's possible to retrieve values from a CSV-file ( Import-CSV ) and use them in the Param block so they become available in the drop down box of the PowerShell ISE when constructing the Cmdlet arguments? A bit in the same way that $Type works now, but then with values from the import file. Function New-Name { Param ( [parameter(Position=0,

问题 I am trying to do some string concatenation/formatting, but it's putting all the parameters into the first placeholder. Code function CreateAppPoolScript([string]$AppPoolName, [string]$AppPoolUser, [string]$AppPoolPass) { # Command to create an IIS application pool $AppPoolScript = "cscript adsutil.vbs CREATE ""w3svc/AppPools/$AppPoolName"" IIsApplicationPool`n" $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/WamUserName"" ""$AppPoolUser""`n" $AppPoolScript +=

问题 I have a windows form that I am asking a user to enter a pcname in textbox1 and then trying to use SqlDataReader to the read from the database to get the pc ipaddress and then map the pc drive to my local pc. But for some reason when I use the textbox within the SQL parameter it's not working. But when I replace the textbox1.text with the actual pcname it works fine. Hopefully someone can help me find out why the parameter isn't working correctly. Here is my code: public void button1_Click

问题 The below is just an example of the functionality.
