Dynamic Web TWAIN常见问题（六）：编程问题-如何使用SSL？

Dynamic Web TWAIN正式版

问题1：如何上传到Web服务器/strong>

答：代码如下

DWObject = document.getElementById("dwtcontrolContainer"); = document.getElementById("dwtcontrolContainer");//dwtcontrolContainer is the id of the Dynamic Web TWAIN on the page (An object or an embed).//dwtcontrolContainer is the id of the Dynamic Web TWAIN on the page (An object or an embed).function btnScan_onclick() function btnScan_onclick(){{DWObject.SelectSource();DWObject.SelectSource();DWObject.OpenSource();DWObject.OpenSource();DWObject.AcquireImage();DWObject.AcquireImage();}}function btnUpload_onclick() function btnUpload_onclick(){{var strActionPage;var strActionPage;var strHostIP;var strHostIP;var CurrentPathName = unescape(location.pathname); // get current PathName in var CurrentPathName = unescape(location.pathname); // get current PathName inplain ASCIIvar CurrentPath = CurrentPathName.substring(0, CurrentPathName.lastIndexOf("/") var CurrentPath = CurrentPathName.substring(0, CurrentPathName.lastIndexOf("/")+ 1); + 1);strActionPage = CurrentPath + "SaveToFile.aspx"; //the ActionPage's file path= CurrentPath + "SaveToFile.aspx"; //the ActionPage's file pathstrHostIP = "localhost"; //The host's IP or name = "localhost"; //The host's IP or nameDWObject.HTTPPort = 80; DWObject.HTTPPort = 80;DWObject.HTTPUploadThroughPost(strHostIP,0,strActionPage,"imageData.tif");DWObject.HTTPUploadThroughPost(strHostIP,0,strActionPage,"imageData.tif");if (DWObject.ErrorCode != 0)if (DWObject.ErrorCode != 0)alert(DWObject.ErrorString);(DWObject.ErrorString);else //succeedelse //succeedalert("Image Uploaded successfully");("Image Uploaded successfully");}}

问题2：如何使用ADF们希望将每个文档保存在单独的文件中。

答：代码如下

var iDocumentCounter =0; iDocumentCounter =0;function BeginScan(){function BeginScan(){    DWObject.OpenSource();DWObject.OpenSource();    DWObject.IfShowUI = false;DWObject.IfShowUI = false;    DWObject.IfDisableSourceAfterAcquire = true;DWObject.IfDisableSourceAfterAcquire = true;    If(DWObject.Duplex != EnumDWT_DUPLEX.TWDX_NONE)If(DWObject.Duplex != EnumDWT_DUPLEX.TWDX_NONE)        DWObject.IfDuplexEnabled = true; //enable duplexDWObject.IfDuplexEnabled = true; //enable duplexDWObject.IfFeederEnabled = true;DWObject.IfFeederEnabled = true;    if (DWObject.IfFeederEnabled == true){if (DWObject.IfFeederEnabled == true){         DWObject.XferCount = -1;DWObject.XferCount = -1;         if(DWObject.IfFeederLoaded == True)if(DWObject.IfFeederLoaded == True)             DWObject.AcquireImage();DWObject.AcquireImage();    }}}}function DWObject_OnPosttransfer(){function DWObject_OnPosttransfer(){iDocumentCounter = iDocumentCounter + 1;= iDocumentCounter + 1;if(DWObject.SaveAsBMP("C:\Image\" + iDocumentCounter + ".bmp", 0) == false)if(DWObject.SaveAsBMP("C:\Image\" + iDocumentCounter + ".bmp", 0) == false)    alert( DWObject.ErrorString);( DWObject.ErrorString);}}

问题3：如何使用SSL/strong>

答：您可以使用IfSSL属性。以下JavaScript示例显示了如何使用IfSSL属性。

function btnUpload_onclick()  btnUpload_onclick(){{   DWObject.HTTPPort = 80; DWObject.HTTPPort = 80;   DWObject.IfSSL = false; // if 80 is the port number of DWObject.IfSSL = false; // if 80 is the port number ofnon-secure port-secure port   /* /*   DWObject.HTTPPort = 443;   DWObject.IfSSL = true; // if 443 is the port number of secureport   */   DWObject.HTTPUploadThroughPost("127.0.0.1", 0, DWObject.HTTPUploadThroughPost("127.0.0.1", 0,"/SaveToFile.php", "imageData.jpg");"/SaveToFile.php", "imageData.jpg");   if (DWObject.ErrorCode != 0)if (DWObject.ErrorCode != 0)      alert(DWObject.ErrorString);(DWObject.ErrorString);   else //succeedelse //succeed     alert("Successful");("Successful");}}
