如何签名使用cosign SOAP API的图形签名

Question

我想使用CoSign Web servies API签署pdf文件。我已经尝试过代码示例，并且能够成功签名。我正在使用开发者帐户，并且已经创建了多个图形签名，但生成的签名不包含任何图像（仅限文本信息），尽管我已将appearanceMask设置为图形图像。

这里是我使用的示例代码：

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; 
      }

     return true; 
    } 
}

既然你不是在您的帐户余弦单个图形签名，则必须注明默认的使用在你的SAPI代码签名。

一个简单的方法是通过提供缺省图形签名的名称作为配置值的一部分。将下面的代码片段添加到您的代码中：

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);
