Question

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，我能够成功签名。我使用的是开发者帐户，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appearanceMask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);

        optInputs.setSAPISigFieldSettings(sigFieldSettings);
        optInputs.setReturnPDFTailOnly(Boolean.TRUE);

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

        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 {

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

一种简单的方法是通过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);

如何使用docusign SOAP API使用图形图像签名进行签名
