我正在尝试使用 CoSign Web 服务 API 签署 pdf 文件。我已经尝试了代码示例，并且能够成功签名。我正在使用开发人员帐户，并且我创建了几个图形签名，但生成的签名不包含任何图像（仅文本信息），尽管我已将外观掩码设置为图形图像。

这是我正在使用的示例代码：

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

        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 + "'.");

由于您的 CoSign 帐户中有多个图形签名，因此您必须指明用于登录 SAPI 代码的默认签名。

一种简单的方法是提供默认图形签名的名称作为配置值的一部分。将以下代码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);
