An external system calls up the URL of the Labordatenbank Webservice with username and password and gets back the data record of the evaluation.
To make an evaluation available as web services for external systems, go to Edit evaluation and select "Activate HTTP authentication" (see figure) and assign a user name and password for HTTP authentication (Information on HTTP authentication).
Once data retrieval via HTTP authentication is enabled, data can be retrieved from an external system using the following URLs (replacing the X
in the URL with the number of the evaluation).
https://labordatenbank.com/demo/stats/view/X/https
https://labordatenbank.com/demo/stats/view/X/https_json
https://labordatenbank.com/demo/stats/view/X/https_json/VAR0/VAR1/VAR2/VAR3/VAR4/DATE/
The following values are possible for the variable DATE
: today, yesterday, last_3_days, this_month, last_month, last_6_month, last_12_month, this_year, last_year
The data format is defined in the evaluation. See: Create SQL reports
If a transformation code is stored, the result of the transformation is transmitted.
The following is a sample code of how the retrieval of the evaluation could be implemented by an external system:
$url = "https://labordatenbank.com/demo/stats/view/**X**/https_json";
$username = '**abc**';
$password = '**
//Retrieve evaluation
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERPWD, "$username:$password");
$json_data = curl_exec($curl);
curl_close($curl);
echo $json_data;
The support of any scripts is not part of the standard support of the laboratory database. The examples included here are for assistance only and do not guarantee success.
Example 1
### Settings ###
$downloadDirectory = ".\download\"
$uri = "http://labordatenbank.com/demo/stats/view/1/https_json"
$user = "testuser"
$pass = "testpassword"
#####################
$b64 = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("${user}:$pass"))
$headers = @{
"Authorization" = "Basic $b64"
}
$download = Invoke-WebRequest -Uri $uri -Headers $headers -UseBasicParsing
$content = [System.Net.Mime.ContentDisposition]::new($download.Headers["Content-Disposition"])
$fileName = $content.FileName
$fullPath = Join-Path -Path $downloadDirectory -ChildPath $fileName
Invoke-WebRequest -Uri $uri -Headers $headers -OutFile $fullPath
Example 2
### Settings ###
$downloadDirectory = "XXX"
$uri = "https://labordatenbank.com/XXX/stats/view/XXX/https_json"
$user = "XXX"
$pass = "XXX"
$logFileName = "auswertungen.log"
$fullLogPath = Join-Path -Path $downloadDirectory -ChildPath $logFileName
Start-Transcript "$fullLogPath" -Append
Base64 decoding¶
$b64 = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("${user}:$pass"))
$headers = @{
"Authorization" = "Basic $b64"
}
Download¶
$download = Invoke-RestMethod -Uri $uri -Headers $headers -UseBasicParsing
if($downloadDirectory){
foreach($entry in $download){
$downloadLink = $entry.'Download-Link'
$fileName = $entry.Dateiname
$fullPath = Join-Path -Path $downloadDirectory -ChildPath $fileName
Write-Host "<--- $fileName --->"
if(![System.IO.File]::Exists($fullPath)){
Invoke-WebRequest -Uri $downloadLink -OutFile $fullPath
if($fullPath){
Write-Host "$filename Downloaded successfully." -ForegroundColor Green
} else {
Write-Host "Error when downloading the file." -ForegroundColor Red
}
} else {
Write-Host "The file $fileName already exists!" -ForegroundColor Red
}
}
} else {
Write-Host "The path could not be found!" -ForegroundColor Red
