如何使用CoSign Signature Soap API添加图形图像签名

Question

如果可能，请添加一些代码片段。我用Java编码。

DSS：我想使用CoSign Signature Soap API添加多个图形图像签名，我该如何实现它？如果可能的话，添加一些代码片段。

这里是在Java代码示例，演示如何使用余弦签名SOAP API添加图形签名：

public static void AddGraphicalImage(String username, String domain, String password, byte[] imageBuffer, String imageName) throws Exception { 
    try { 
     SignRequest request = new SignRequest(); 

     RequestBaseType.OptionalInputs optInputs = new RequestBaseType.OptionalInputs(); 

     // Set signature type 
     optInputs.setSignatureType("http://arx.com/SAPIWS/DSS/1.0/set-graphic-image"); 

     // Set user credentials 
     ClaimedIdentity claimedIdentity = new ClaimedIdentity(); 
     NameIdentifierType nameIdentifier = new NameIdentifierType(); 
     nameIdentifier.setValue(username); 
     nameIdentifier.setNameQualifier(domain); 
     CoSignAuthDataType coSignAuthData = new CoSignAuthDataType(); 
     coSignAuthData.setLogonPassword(password); 
     claimedIdentity.setName(nameIdentifier); 
     claimedIdentity.setSupportingInfo(coSignAuthData); 
     optInputs.setClaimedIdentity(claimedIdentity); 

     // Set graphical image data 
     GraphicImageType graphicImage = new GraphicImageType(); 
     graphicImage.setGraphicImage(imageBuffer); 
     graphicImage.setDataFormat(Long.valueOf(6)); //JPG 
     graphicImage.setGraphicImageName(imageName); 
     optInputs.setGraphicImageToSet(graphicImage); 

     request.setOptionalInputs(optInputs); 

     // Initiate service client 
     DSS client = new DSS(new URL("https://prime.cosigntrial.com:8080/sapiws/dss.asmx")); 

     // Send the request 
     DssSignResult response = client.getDSSSoap().dssSign(request); 

     // Check result 
     String errmsg = "" + response.getResult().getResultMajor(); 
     if (errmsg.compareTo("urn:oasis:names:tc:dss:1.0:resultmajor:Success") == 0) { 
      System.out.println("Graphical image was added successfully!"); 
      return; 
     } 
     else { 
      throw new Exception(response.getResult().getResultMessage().toString()); 
     } 
    } 
    catch (Exception e) { 
     System.out.println("Error: " + e.getMessage()); 
     e.printStackTrace(); 
    } 
}
