如何簽名使用cosign SOAP API的圖形簽名

Question

我想使用CoSign Web servies API簽署pdf文件。我已經嘗試過代碼示例，並且能夠成功簽名。我正在使用開發者帳戶，並且已經創建了多個圖形簽名，但生成的簽名不包含任何圖像（僅限文本信息），儘管我已將appearanceMask設置爲圖形圖像。

這裏是我使用的示例代碼：

package trial; 

import com.arx.sapiws.dss._1.*; 
import java.io.File; 
import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.net.MalformedURLException; 
import java.net.URL; 
import oasis.names.tc.dss._1_0.core.schema.*; 
import oasis.names.tc.saml._1_0.assertion.NameIdentifierType; 

public class CosignHelloWorld { 

    public static void main(String[] args) throws MalformedURLException { 

     String fileName = "D:/demo - Copy.pdf"; 
     String signerUsername = ""; 
     String signerPassword = ""; 

     System.out.println("Trying to sign '" + fileName + "' by '" + signerUsername + "' with password '" + signerPassword + "' ..."); 
     if (!checkFile(fileName)) { 
      System.out.println("Cannot find '" + fileName + "' or it is read/write protected. Aborting."); 
      return; 
     } 

     //set document properties 
     DocumentType.Base64Data corePDFBytes = new DocumentType.Base64Data(); 
     byte[] fileBytes = getPDFBytes(fileName); 
     corePDFBytes.setValue(fileBytes); 
     corePDFBytes.setMimeType("application/pdf"); 
     DocumentType myDoc = new DocumentType(); 
     myDoc.setBase64Data(corePDFBytes); 

     // set signer - USERNAME/DOMAIN 
     NameIdentifierType cosignUserProps = new NameIdentifierType(); 
     cosignUserProps.setValue(signerUsername); 
     cosignUserProps.setNameQualifier(" "); 

     // set signer - PASSWORD 
     CoSignAuthDataType cosignPassword = new CoSignAuthDataType(); 
     cosignPassword.setLogonPassword(signerPassword); 

     // set signer - USERNAME+PASSWORD 
     ClaimedIdentity cosignUser = new ClaimedIdentity(); 
     cosignUser.setName(cosignUserProps); 
     cosignUser.setSupportingInfo(cosignPassword); 

     //set signature field settings 
     SAPISigFieldSettingsType sigFieldSettings = new SAPISigFieldSettingsType(); 
     sigFieldSettings.setName("SigField"); 
     sigFieldSettings.setInvisible(Boolean.FALSE); //visible 
     sigFieldSettings.setX(150); 
     sigFieldSettings.setY(110); 
     sigFieldSettings.setWidth(150); 
     sigFieldSettings.setHeight(50); 
     sigFieldSettings.setDependencyMode(DependencyModeEnum.INDEPENDENT); 
     sigFieldSettings.setSignatureType(SignatureTypeEnum.DIGITAL); 
     sigFieldSettings.setAppearanceMask(11L); 
     sigFieldSettings.setEmptyFieldLabel(""); 
     sigFieldSettings.setPage(1); 

     //initiate request components 
     RequestBaseType.InputDocuments inputs = new RequestBaseType.InputDocuments(); 
     inputs.getOtherOrDocumentHashOrTransformedData().add(myDoc); 

     RequestBaseType.OptionalInputs optInputs = new RequestBaseType.OptionalInputs(); 
     optInputs.setSignatureType("http://arx.com/SAPIWS/DSS/1.0/signature-field-create-sign"); 
     optInputs.setClaimedIdentity(cosignUser); 
     optInputs.setSAPISigFieldSettings(sigFieldSettings); 
     optInputs.setReturnPDFTailOnly(Boolean.TRUE); 

     //initiate connection to COSign SAPI service 
     DSS service = new DSS(new URL("https://prime.cosigntrial.com:8080/sapiws/dss.asmx")); 
     DSSSoap port = service.getDSSSoap12(); 

     //initiate request 
     SignRequest request = new SignRequest(); 
     request.setOptionalInputs(optInputs); 
     request.setInputDocuments(inputs); 
     request.setRequestID("DummyRequestId"); 

     //make the call 
     DssSignResult result = port.dssSign(request); 

     //CHECK RESULT: 
     ResponseBaseType.Result rc = result.getResult(); 
     String errmsg = rc.getResultMajor(); 
     if (errmsg.compareTo("urn:oasis:names:tc:dss:1.0:resultmajor:Success") != 0) { 
      System.out.println("Cannot sign '" + fileName + "' got: " + rc.getResultMessage().getValue()); 
      return; 
     } 

     System.out.println("Trying to append signature to '" + fileName + "' ('" + signerUsername + "') ..."); 

     // IF OK Get the signature: 
     DssSignResult.SignatureObject sigObj = result.getSignatureObject(); 
     DssSignResult.SignatureObject.Base64Signature sigBase64 = sigObj.getBase64Signature(); 

     try { 
      FileOutputStream fos = new FileOutputStream(fileName, true); 
      fos.write(sigBase64.getValue()); 
      fos.close(); 
     } catch (Exception e) { 
      System.out.println("Error writing to PDF file: " + e.getMessage()); 
      return; 
     } 

     System.out.println("Signature of '" + signerUsername + "' appended to '" + fileName + "'."); 
    } 

    private static byte[] getPDFBytes(String FileName) { 
     byte[] pdf; 
     // READ THE FILE INTO BUFFER 
     try { 
      File file = new File(FileName); 

      if (!file.canRead()) { 
       return null; 
      } 

      if (!file.canWrite()) { 
       return null; 
      } 

      pdf = new byte[(int) file.length()]; 
      FileInputStream fos = new FileInputStream(file); 
      fos.read(pdf, 0, (int) file.length()); 
      fos.close(); 

     } catch (Exception e) { 
      return null; 
     } 
     return pdf; 
    } 

    private static boolean checkFile(String fileName) { 
     try { 
      File file = new File(fileName); 

      if (!file.canRead()) { 
       return false; 
      } 

      if (!file.canWrite()) { 
       return false; 
      } 
     } catch (Exception e) { 
      return false; 
     } 
     return true; 
    } 
}

既然你不是在您的帳戶餘弦單個圖形簽名，則必須註明默認的使用在你的SAPI代碼簽名。

一個簡單的方法是通過提供缺省圖形簽名的名稱作爲配置值的一部分。將下面的代碼片段添加到您的代碼中：

ArrayOfConfValueType confValArray = new ArrayOfConfValueType(); 
ConfValueType confVal = new ConfValueType(); 
confVal.setConfValueID(ConfIDEnum.GR_SIG_PREF_NAME); 
confVal.setStringValue("{GRAPHICAL_IMAGE_NAME}"); 
confValArray.getConfValue().add(confVal); 
optInputs.setConfigurationValues(confValArray);
