截圖機-VB

本demo展示如何使用Visual Basic程式語言呼叫線上截圖機API。

安裝

首先，您需要在 www.screenshotmachine.com 網站上建立免費/進階帳戶。註冊後，您將在您的用戶個人資料中看到您的客戶金鑰。這裡還保留了秘密短語。當您的 API 呼叫是從公開網站呼叫時，請始終使用秘密短語。

在腳本中設定您的客戶金鑰和秘密短語（如果需要）：

    Dim customerKey As String = "PUT_YOUR_CUSTOMER_KEY_HERE"
    Dim secretPhrase As String = "" REM leave secret phrase empty, If Not needed 

網站截圖API

設定附加選項以滿足您的需求：

    Dim options As New Dictionary( Of String , String )
    REM mandatory parameter
    options.Add( "url" , "https://www.google.com" )
    REM  all next parameters are optional, see our website screenshot API guide for more details
    options.Add( "dimension" , "1366x768" ) REM Or "1366xfull" For full length screenshot
    options.Add( "device" , "desktop" )
    options.Add( "format" , "png" )
    options.Add( "cacheLimit" , "0" )
    options.Add( "delay" , "200" )
    options.Add( "zoom" , "100" )

有關選項的更多資訊可以在我們的網站螢幕截圖 API 中找到。

範例程式碼

 Imports System.Net

Public Class Client

    Public Shared Sub Main(args() As String )
        Dim customerKey As String = "PUT_YOUR_CUSTOMER_KEY_HERE"
        Dim secretPhrase As String = "" REM leave secret phrase empty, If Not needed

        Dim options As New Dictionary( Of String , String )
        REM mandatory parameter
        options.Add( "url" , "https://www.google.com" )
        REM  all next parameters are optional, see our website screenshot API guide for more details
        options.Add( "dimension" , "1366x768" ) REM or "1366xfull" for full length screenshot
        options.Add( "device" , "desktop" )
        options.Add( "format" , "png" )
        options.Add( "cacheLimit" , "0" )
        options.Add( "delay" , "200" )
        options.Add( "zoom" , "100" )

        Dim sm As ScreenshotMachine = New ScreenshotMachine(customerKey, secretPhrase)
        Dim apiUrl As String = sm.GenerateScreenshotApiUrl(options)
        REM use final apiUrl where needed
        Console.WriteLine(apiUrl)
    End Sub

End Class

產生的apiUrl連結可以放置在<img>標記中或稍後在您的業務邏輯中使用。

如果您需要將擷取的螢幕截圖儲存為影像，只需呼叫：

    Dim apiUrl As String = sm.GenerateScreenshotApiUrl(options)

    REM or save screenshot directly
    Dim client As New WebClient()
    Dim output As String = "output.png"
    client.DownloadFile(apiUrl, output)
    Console.WriteLine( "Screenshot saved as " + output)

擷取的螢幕截圖將作為output.png檔案保存在目前目錄中。

網站轉 PDF API

設定 PDF 選項：

    Dim options As New Dictionary( Of String , String )
    REM mandatory parameter
    options.Add( "url" , "https://www.google.com" )
    REM  all next parameters are optional, see our website to PDF API guide for more details
    options.Add( "paper" , "letter" )
    options.Add( "orientation" , "portrait" )
    options.Add( "media" , "print" )
    options.Add( "bg" , "nobg" )
    options.Add( "delay" , "2000" )
    options.Add( "scale" , "50" )

有關選項的更多資訊可以在我們的 PDF API 網站中找到。

範例程式碼

 Imports System.Net

Public Class ClientPdf

    Public Shared Sub Main(args() As String )
        Dim customerKey As String = "PUT_YOUR_CUSTOMER_KEY_HERE"
        Dim secretPhrase As String = "" REM leave secret phrase empty, If Not needed

        Dim options As New Dictionary( Of String , String )
        REM mandatory parameter
        options.Add( "url" , "https://www.google.com" )
        REM  all next parameters are optional, see our website to PDF API guide for more details
        options.Add( "paper" , "letter" )
        options.Add( "orientation" , "portrait" )
        options.Add( "media" , "print" )
        options.Add( "bg" , "nobg" )
        options.Add( "delay" , "2000" )
        options.Add( "scale" , "50" )

        Dim sm As ScreenshotMachine = New ScreenshotMachine(customerKey, secretPhrase)
        Dim pdfApiUrl As String = sm.GeneratePdfApiUrl(options)

        REM save PDF file
        Dim client As New WebClient()
        Dim output As String = "output.pdf"
        client.DownloadFile(pdfApiUrl, output)
        Console.WriteLine( "PDF saved as " + output)
    End Sub

End Class

捕獲的 PDF 將作為output.pdf文件保存在當前目錄中。
