Docusign系列(四) - Docusign的嵌入式签名


之前谈到的Dicusign,都是发送一封邮件给到收件人,然后收件人完成签名的一个过程,那么有的时候,当我们需要直接在页面上打开用户签名的界面,而不是通过邮件的形式,那么就需要开启Docusign的嵌入式签名过程

整体步骤参考 Docusign系列(三)- SOAP方式调用Docusign,本质上来讲,嵌入式签名的形式,即将发送到用户的那封信件的链接,在页面上完成跳转,所以我们首先写一个页面按钮:打开Docusign签名链接(图左),当你点击按钮,会直接跳转到Docusign的签名页面(图右)

 

 

 

 页面代码很简单,通过按钮调用Docusign的SOAP接口

<apex:page controller="ShowButtonCtrl" showHeader="false" sidebar="false">
    <apex:form >
        <apex:pagemessages />
        <apex:pageBlock >
            <apex:commandButton value="打开Docusign签名链接" action="{!testFunction}"/>
        </apex:pageBlock>
    </apex:form>
</apex:page>
public class ShowButtonCtrl {
    
    public String testFunction(){
        String docusignurl = DocusignDemo2.sendWithDocusign('8002w000000HXkJ');
        return docusignurl;
    }
}

那么关于Docusign部分的代码该怎么做呢?

首先是关于收件人,需要添加新的参数

// 设定一个 Client User Id
String signer_user_id = '1';

// 第一个签字
DocusignApi.Recipient firstSigner = new DocusignApi.Recipient();
firstSigner.ID = 1;
firstSigner.Type_x = 'Signer';// 收件人类型 - Signer表示需要签字
firstSigner.RoutingOrder = 1;// 签字顺序
firstSigner.Email = 'XXXXXXX';
firstSigner.UserName = '第一个签字';
firstSigner.RequireIDLookup = false;

// 嵌入式签名的参数
firstSigner.CaptiveInfo = new DocuSignAPI.RecipientCaptiveInfo();
firstSigner.CaptiveInfo.ClientUserID = signer_user_id;
firstSigner.CaptiveInfo.EmbeddedRecipientStartURL = 'SIGN_AT_DOCUSIGN';

然后在通过Docusign生成EnvelopeID之后,获取需要跳转的链接:

// 第一步:创建assertion
DocuSignAPI.RequestRecipientTokenAuthenticationAssertion assertion  = new DocuSignAPI.RequestRecipientTokenAuthenticationAssertion();
assertion.AssertionID = '1';
assertion.AuthenticationInstant = Datetime.now();
assertion.AuthenticationMethod = 'Password';
assertion.SecurityDomain = 'DS_Recipe_Signer_View_Controller';

// Salesforce 环境域名
String baseUrl = URL.getSalesforceBaseUrl().toExternalForm();
String signer_return_url = baseURL + '?cId=' + recordId;

String return_url_base = signer_return_url;

if(return_url_base.contains('?')) {
    return_url_base += '&event=';
}else {
    return_url_base = return_url_base += '?event=';
}

System.debug(LoggingLevel.INFO , '**** return_url_base:' + return_url_base);

// 第二步:为电子签名的不同结果创建重定向URL
DocuSignAPI.RequestRecipientTokenClientURLs urls = new DocuSignAPI.RequestRecipientTokenClientURLs();        
urls.OnSigningComplete  = baseURL + '/apex/welcome?conId=' + recordId;
urls.OnViewingComplete  = return_url_base + 'viewing_complete';
urls.OnCancel           = return_url_base + 'cancel';
urls.OnDecline          = return_url_base + 'decline';
urls.OnSessionTimeout   = return_url_base + 'session_timeout';
urls.OnTTLExpired       = return_url_base + 'ttl_expired';
urls.OnException        = baseURL + '/apex/welcome?conId=' + recordId;
urls.OnAccessCodeFailed = return_url_base + 'failed_access_code';
urls.OnIdCheckFailed    = return_url_base + 'failed_id_check';
urls.OnFaxPending       = return_url_base + 'fax_pending';

System.debug(LoggingLevel.INFO , '**** return_url_base:' + return_url_base);

String signer_view_url;
Boolean no_error = true;

try {
    // 第三步:调用Docusign请求
    signer_view_url = dsApi.RequestRecipientToken(envelopeId, signer_user_id, firstSigner.UserName, firstSigner.Email, assertion, urls);
    System.debug(LoggingLevel.INFO , '**** Received signer_view_url:' + signer_view_url);
} catch ( CalloutException e) {
    System.debug(LoggingLevel.INFO , '**** Exception - ' + e );
    String error_code = 'Problem: ' + e;
    String error_message = error_code;
    no_error = false;
}

在搞定上面的内容之后,当Docusign签订完成会跳转到 'welcome' 这个自定义页面,

 

 整体来看,在SOAP的接触上使用嵌入式签名还是很简单的,这样就可以让Docusign能在更多的地方被使用,比如在我们发送出去的Email中,或者其他自定义页面上,赋予了这种电子签名更广泛的应用空间

需要注意的是,这种嵌入式签名的有效期仅仅五分钟,同时在默认情况下,Docusign不会发送之前我们看到的Docusign请求签名的邮件给收件人,这一点从需求上不难理解,毕竟在页面上把合同啥的都签了,也不需要额外的邮件提醒了,不过Docusign也不是完全关闭了这样的通道,在Docusign的管理员界面中,选择Signing Setting页签

 

 在这里,你可以关闭或者启用是否要在嵌入式场景下发送邮件给签名者,同时设置一个 CaptiveInfo 参数(参数说明

最后,附上DocusignDemo2 类的完整代码

public class DocusignDemo2 {
    public static String USERID = 'XXXXX';
    public static String ACCOUNTID = 'XXXXX';
    public static String PASSWORD = 'XXXXXX';
    public static String INTEGRATORKEY = 'XXXXXX';
    public static String ENDPOINT = 'https://demo.docusign.net/api/3.0/dsapi.asmx';
    
    public static String sendWithDocusign(String recordId){
        Contract con = [SELECT id FROM Contract WHERE Id=:recordId];
        
        DocusignApi.DSAPIServiceSoap dsApi = new DocusignApi.DSAPIServiceSoap();
        dsApi.endpoint_x = ENDPOINT;
        
        //Set Authentication
        String auth = '<DocuSignCredentials>'
                        + '<Username>'+ USERID + '</Username>' 
                        + '<Password>' + PASSWORD + '</Password>' 
                        + '<IntegratorKey>' + INTEGRATORKEY + '</IntegratorKey>' 
                    + '</DocuSignCredentials>';
        System.debug('Setting authentication to: ' + auth);
            
        dsApi.inputHttpHeaders_x = new Map<String, String>();
        dsApi.inputHttpHeaders_x.put('X-DocuSign-Authentication', auth);
        
        // 发送Docusign中的模板
        DocuSignAPI.TemplateReference templateReference = new DocuSignAPI.TemplateReference();
        templateReference.Template = 'XXXXXXXXX';
        templateReference.TemplateLocation = 'Server';
        
        DocusignApi.ArrayOfTemplateReference templateReferences = new DocusignApi.ArrayOfTemplateReference();
        templateReferences.TemplateReference = new DocusignApi.TemplateReference[]{templateReference};

        // 启用嵌入式的同时启用远程签名
        firstSigner.CaptiveInfo = new DocuSignAPI.RecipientCaptiveInfo();
        firstSigner.CaptiveInfo.ClientUserID = signer_user_id;
     // EmbeddedRecipientStartURL –这是发件人提供的用于重定向收件人的有效URL字符串。
     // 使用此选项时,嵌入式收件人仍会像远程收件人一样从DocuSign接收电子邮件,但是当单击电子邮件中的文档链接时,
     // 收件人将通过DocuSign重定向到该URL以完成其操作
     // 路由到URL时,由发送者的系统(服务器响应URL)决定是否请求接收者令牌启动签名会话。
     // 如果此节点使用值SIGN_AT_DOCUSIGN,则收件人将直接在DocuSign上定向到嵌入式签名或查看过程。
     // 签名或查看操作由DocuSign系统启动,并且交易活动和完成证书记录将对此进行反映。在所有其他方面,
